Audi grandsphere concept – First class toward the future

Audi grandsphere concept

First class toward the future

The private jet for the road – At the IAA 2021, Audi is presenting the Audi grandsphere concept study. Like a first class flight, the 5.35 m (17.6 ft.) long grandsphere sedan combines the luxury of private travel in the greatest of comfort with a comprehensive onboard experience offering.

Level 4 automated driving makes new dimensions of freedom possible: in this mode, the interior turns into a spacious sphere of experience without a steering wheel, pedals, or displays. And the front seats become a first class lounge with maximum space, freer views, and access to all the functions of a holistic digital ecosystem that the Audi grandsphere is integrated into.

As the second of three “sphere” concept cars from the brand with the four rings, the Audi grandsphere has a special place. That is because the technologies and design features assembled in it will turn up again within a few years in future Audi series. The Audi grandsphere concept illustrates the brand’s claim that it is becoming the trendsetter at the top of the automotive industry for technological transformation and completely new, holistic mobility offerings.

The electrically driven roadster Audi skysphere concept debuted in August 2021 – it was a spectacular vision of an automatically driving GT that transforms into a self-driving sports car with a variable wheelbase. These two concept cars – as well as the Audi urbansphere, which will appear as the third part of the trio in 2022 – are linked by their overall concept, which is derived from their ability to drive automatically at level 4. Audi is working with CARIAD, the Volkswagen Group’s software think tank, toward introducing that technology in the second half of the decade.

Level 4: not only does it change the interior space of the traditional driver-oriented cockpit and passenger seats into a spacious lounge as soon as the steering wheel and pedals are reduced. At the same time, it opens up new levels of freedom for all the passengers. That is because the Audi grandsphere not only frees the driver from the tasks of driving whenever possible, but at the same time also offers everyone onboard a wide range of options to use that freedom for individually variable experiences: communication or relaxation, work or withdrawal into a private sphere as desired. The Audi grandsphere concept transforms from being strictly an automobile in an “experience device.“

Thanks to Audi’s own services and the ability to integrate digital services, the possibilities are nearly endless. These can be used to access a variety of service options related to the current trip – such as designing a spectacular scenic route, as well as restaurant or hotel options. The vehicle also takes care of everyday tasks that go beyond the ride itself. For example, the autonomous Audi grandsphere concept picks up its passengers with information about their current destination and independently handles parking and charging.

Customized infotainment options are also available, such as seamless integration of onboard streaming from music and video providers that have been used previously. In an additional step, Audi will keep personalized and exclusive options available in the future – concerts, cultural events, or even sporting events that customers are invited to.

The Audi grandsphere concept illustrates the brand’s claim that it defines the progressive luxury of the future: for Audi, that includes the option of new high-class experiences, enabled by digitalization, as well as a holistic approach to sustainability with the goal of carbon neutrality in the near future along the entire value chain.

First class for the future times three

Audi skysphere, Audi grandsphere, and Audi urbansphere are the three concept cars that the brand with the four rings is using to showcase its vision of progressive luxury. In the process, Audi is creating a vehicle experience that goes far beyond the purpose of merely spending time in a car to get from point A to point B, and even far beyond the driving experience itself.

These concept cars feature a new design that ultimately reimagines the interior, the passenger compartment, as the center of the vehicle and no longer subordinates the passenger experience to the requirements of the technology. This is reflected in the variable layout of the interior, the disappearance of the controls, and the sheer expanse of the cabin, in addition to linking them to new service offerings.

The design process – from the inside out

Even the “sphere” in the name sends a signal: the heart of the Audi skysphere, grandsphere, and urbansphere concept vehicles is always the interior. The drive system and the handling are no longer at the top of the design specifications in this new generation of cars. Instead, the starting point is the interior, the occupants’ living and experience sphere while traveling. Their needs and desires shape the space, the architecture, and the functions. With that reassessment, the design process itself changes. At the beginning of all discussions, the focus is directed toward the interior and its design. Only after that do we design the package, exterior lines, and proportions that shape the car into a total work of art, along with the technological premises.

Space, form, function – the interior

The doors of the Audi grandsphere concept are reversed so front and back touch; there is no B-pillar. The whole world of the interior opens up to passengers as soon as they climb in. But even before that, the Audi grandsphere has identified its passengers with a pathway identification – an innovative feature – that opens the doors and welcomes them with individually staged displays and ambient light. The driver and passenger positions are automatically detected and an array of personal comfort features – such as the climate control settings and the seats – are adjusted for the individual seats. At the same time, the infotainment system accesses the passengers’ most recently used services and seamlessly resumes them inside the car. For instance, a video that a passenger was streaming on a tablet is automatically played back over the display surface in the Audi grandsphere. On the driver’s side, on the other hand, the projection surface automatically picks up on displaying the news the occupant was reading before getting in.

In the interior, the lines on the decorative surfaces and functional elements are emphatically horizontal. The open, broad interior supports the impression of a unique space and the lack of a steering wheel, pedals, or conventional dashboard create a feeling of openness and breadth.

The large glass surfaces, expansive windshield, and transparent ceiling also emphasize that feeling. The same goes for the particular geometry of the side windows: their upper half is distinctively angled – the widest part is just slightly above eye level. It is a trick that Audi demonstrated for the first time in 2017 with its futuristic AI:CON concept car and which is now moving toward series production.

The change in the comfort zone is radical: if the boss’ seat is in the back in a conventional sedan, first class has now shifted forward into the front row. That is because it is no longer necessarily subordinated, first and foremost, to the driving function and the controls. In level 4 driving, the steering wheel and pedals disappear and the front area of the cabin becomes actual free space in all its breadth, with a perfect view through the large front and side windows, as well as maximum possibilities for movement.

The interior appears particularly wide when the two individual front seats are pushed all the way back. The Audi grandsphere is a 2+2-seater. An upholstered, two-person bench with an armrest that goes around the side is integrated as a seating option in the back, while both front seats are designed for first class comfort and space.

The seating surfaces and backs of the two seats with integrated belts are visually separate. The side bolsters of the seat backs are discreetly bent, thereby ensuring support while driving through curves. The possible seat positions are optimized for every use: in the upright position, the Audi grandsphere can be perfectly ergonomically controlled – as desired and outside level 4 zones. With the back tilted 40 degrees, passengers can relax and use the infotainment system. Finally, if the back is folded out to 60 degrees, it achieves a perfect resting position. The headrest can be bent 15 degrees forward. Outlets for air that is filtered and temperature controlled – even scented, as desired – as well as speakers that are inaudible to other passengers and allow for a private aural zone are all integrated into this area.

Between the front seats – normally concealed under metallic trim – there is a compact, onboard cooler with two glasses and a designed, elegant bottle for soft drinks. This is another sign of the Audi grandsphere concept’s first class claim.

No fittings, no screens: displays and operation

One surprise when looking around in the Audi grandsphere’s natural-colored, reduced-design interior: neither batteries of dial instruments nor black screens for virtual display concepts are visible before activating the driving functions – the oft-cited digital detox at its finest.

Instead, there are clearly articulated and sedate areas with materials of the highest quality. Wood and wool, synthetic textile fabrics and metal are visible and pleasant to touch as wall cladding, seat covering, and carpeting. Many of these materials, like the hornbeam veneers, come from sustainable cultivation or are made from recycled raw materials. There is no leather in the Audi grandsphere – even this is in keeping with a progressive understanding of luxury, which is always inseparable from sustainability.

Another surprise whenever the vehicle comes to life at the touch of a fingertip: there are displays – but they take the form of projections on the wooden surfaces under the windshield. Depending on the driving status – whether manual with a steering wheel or level 4 – they are either distributed across the entire width of the interior or segmented for the driver and front seat passenger. All the information that is necessary while traveling is there in high resolution and precisely readable.

Alternatively, the projection surfaces can also be used – in automated driving mode – as CinemaScope screens for infotainment content or even as screens for video conferences. In addition, a sensor bar is integrated under the projection surfaces for quick switching between content – for instance, for music or navigation. It shows all the functions and applications that are active in the car. Icons flash for the different menus.

One particular, extremely innovative control element is located near the door cut-out on the interior cladding: the MMI touchless response. If the driver is sitting in the active position behind the steering wheel, far toward the front in the interior, he or she can use that control to haptically select various function menus via a rotary ring and buttons and click through the different levels. A simple, intuitive operation.

If, on the other hand, the driver reclines the seat far to the back during level 4 driving, he or she does not have to do without these comfort items. That is because, at that point, a combination of eye tracking and gesture control are used. A sensor directed at the eye detects the line of sight when the control unit is to be engaged. And the passenger only needs to make analogous hand motions – without leaning over – that are similar to haptic operation and can use the system just as well that way – without touching a thing.

Whether it is eye tracking, gesture or voice control, handwritten input, or touch, the same thing applies to all operation modes: the Audi grandsphere concept adjusts to the individual user and learns his or her preferences and frequently used menus – and on that basis it can not only sensibly complete rudimentary commands, but also give personal proposals directly to the user.

Control panels are even integrated into the armrests on the doors. That way, the car always offers passengers invisible touch surfaces using an optic indicator to show its position. At the same time, there are VR glasses in the armrests on the left and right doors that can be used in conjunction with infotainment options – for instance for the holoride system.

Dynamic monolith – the exterior design

At 5.35 m (17.6 ft.) long, 2 m (6.6 ft.) wide, and 1.39 m (4.6 ft.) high, the Audi grandsphere concept’s measurements reveal this sedan as an unambiguous example of the luxury class automobile. The 3.19 m (10.5 ft.) wheelbase indicates top value, which even overshadows the long version of the current Audi A8. But even more striking than what these figures suggest is the visual impression that it makes upon seeing it for the first time. That is because the Audi grandsphere looks nothing like a traditional sedan, but rather more like a tightly drawn four-door GT with a line the comes straight from the wind tunnel. And it does that while doing without any decor or superfluous flourishes.

In the process, the Audi grandsphere consistently implements the specific conditions of the electric drive system right in the front end – a short overhang, a flat hood, and the windshield that projects far forward as the foremost limit of the large interior. Nonetheless, unlike many electric cars, it does not look futuristic at all, but rather emphasizes traditional beauty ideals. The top edge of the hood is drawn far into the side of the chassis in a horizontal line, suggesting a long engine compartment – all characteristics of a GT. In the rear, that line continues at the same height across the rear wheel well, encompassing the whole cabin and emphasizing its size.

A second horizontal line emanates from the bottom edge of the hood and runs under the side windows and likewise around the entire cabin. This subdivides the door surfaces into horizontally oriented shoulders and the convex verticals below them above the rocker panel. The wheel wells have a soft, yet distinctive shape – typical Audi. The slender rear behind the massive C-pillar is a quote from traditional streamlining. And the dynamically sloping arc of the roofline reveals the grandsphere as part of the Audi Sportback tradition. All lines and all surfaces seem to organically correlate, combining to form one monolithic body.

At 23 inches, the wheels of the Audi grandsphere concept quote an icon from the 1990s – the Audi Avus. At the same time, the six double spokes signal light construction and stability, recalling functional motorsport wheels and the Bauhaus tradition in brand design.

Visible technology – light

In the front end, there is an innovative interpretation of the Singleframe that defines Audi’s look: it is shaped like a flat hexagon. The interior surfaces, behind a transparent covering, are indirectly lit from above while driving – a distinctive, extremely three-dimensionally structured visual effect.

The headlight units on the upper side of the Singleframe look narrow, like focused eyes. The lighting units reference the four rings brand logo: they enlarge and isolate the intersection of two rings into a pupil – a new, unmistakable digital light signature. This means that the size of the light areas can be adjusted according to their function as daytime running lights or as dynamically staged blinkers – depending on the traffic situation – and thereby issue an obvious signal in the interest of safety. The same graphic is also in the rear lighting units – another significant characteristic of the Audi light design.

Drive system and charging

The technology platform of the Audi grandsphere – what is known as the Premium Platform Electric, or PPE – was conceived exclusively for battery-powered electric drive systems and therefore it takes full advantage of that technology. The key element of PPE is a battery module between the axles that holds around 120 kWh of energy in the grandsphere concept. A flat battery layout is possible because Audi uses the entire vehicle base between the axes.

Together with the large wheels, this produces basic proportions that are perfect not only from a design perspective. The core benefits include a long interior and therefore legroom in both rows of seats. Additionally, the absence of a gearbox cover and a cardan tunnel increases spatial comfort in electric cars.

Nonetheless, the Audi grandsphere does not forego the quattro drive system, which is essential to the brand. That is because the concept car has separate electric motors mounted on the front and rear axles that use electronic coordination to deliver all-wheel drive on demand and execute a perfect balance between driving dynamics and energy efficiency. The Audi grandsphere concept’s two electric motors are capable of delivering a total output of 530 kW and a torque of 960 Newton meters.

Fast charging, high range

The heart of the drive system is the 800 volt charging technology. Like the Audi e-tron GT before it, this technology ensures that the battery can be charged with up to 270 kW in a very short time at fast-charging stations.

This strategy makes charging times that approach a refueling stop for a car with a conventional engine possible. Just ten minutes are enough to charge the battery to a level sufficient to power the car more than 300 kilometers (186 miles). In less than 25 minutes, you can charge the 120 kWh battery from 5 to 80 percent.

Together with a range of more than 750 kilometers (466 miles) – depending on the selected drive system and power output – the Audi grandsphere concept is unconditionally suitable for long distances. Furthermore, its range and charging speed keep pace with those of combustion engines, making it the perfect universal car for everyday needs.

In terms of dynamic qualities, the Audi grandsphere concept – as is typical for an electric car – truly outshines its rivals with combustion engines. Thanks to the high torque that is available from the first revolution, acceleration from 0-100 km/h (62 mph) takes just over four seconds; maximum speed is limited in the interest of increased range.

Air suspension and active suspension for maximum comfort

The front wheels are connected via a five-link axle, specially optimized for electric vehicles. In the rear, there is a multi-link axle that, like the front, is made of aluminum. Despite the long wheelbase, the steerable rear wheels provide excellent maneuverability. The luxurious Audi grandsphere concept touring sedan utilizes Audi air suspension – a single chamber system with adaptive dampers. Quite well suited for dynamic driving when necessary it guarantees gentle comfort without noticeable vehicle body movements, under normal conditions.

The reason: the Audi grandsphere concept has active suspension. The high-tech system can separately pull up or push down on each wheel separately in milliseconds via electromechanical actuators. That makes it possible to actively control the state of the chassis in every driving situation and therefore significantly reduce pitching and plunging when accelerating or braking. Thanks to the front camera, which recognizes unevenness, the adjustments happen predictively. The navigation system’s topographical data are also used to integrate curve radii, gradients, and inclines into the system’s projection.

Audi skysphere concept – The future is wide open 2021

Audi skysphere concept (2021)

Audi has unveiled the first member of a new family of concept vehicles, a spectacular roadster. Audi skysphere concept is the name of the electric-powered, two-door convertible whose lines lead directly to the Audi design of tomorrow. With it, the brand is illustrating its vision for the progressive luxury segment of the future, in which the interior becomes an interactive space and the vehicle a platform for captivating experiences. This is being made possible thanks to autonomous driving, a revolutionary redesign of the interior, and a seamless digital ecosystem.

The Audi skysphere concept shows how the brand is redefining luxury in the future – it’s no longer just about driving. The concept car was designed with the clear objective of offering its occupants captivating and world-class experiences.

To give passengers the maximum amount of freedom, the Audi skysphere concept was designed for two different driving experiences: a grand touring experience and a sports experience. This makes use of a spectacular technical detail – the variable wheelbase. Electric motors and a sophisticated mechanism with body and frame components that slide into one another make it possible to vary the wheelbase itself and the exterior length of the car by 250 millimeters. At the same time, the vehicle’s ground clearance is adjusted by 10 millimeters to enhance comfort and driving dynamics.

With the touch of button, the driver can take advantage of their freedom and choose their own driving experience– either they pilot their 4.94-meter-long e-roadster themselves in “Sports” mode with a reduced wheelbase, while the rear-wheel steering ensures that the vehicle remains extremely agile despite its dimensions. Or they can choose to be chauffeured around in a 5.19-meter GT in the autonomous “Grand Touring” driving mode while enjoying the sky and the scenery, maximum legroom, and the services offered by a seamlessly integrated digital ecosystem.

In this mode, the steering wheel and pedals move into an invisible area; the feeling of space in the concept car opens up completely new realms of possibility for such a sporty convertible. Meanwhile, the Audi skysphere automatically keeps an eye on the road and traffic with its sensor system and drives the occupants safely to their destination.

Similar to how the interior design offers a new, contemporary interpretation of luxury, digitization and the ecosystem open up unprecedented levels of freedom and worlds of experience for the vehicle’s passengers. Thanks to Audi’s own services and the ability to integrate digital services, the possibilities are nearly endless. In addition, the passengers can share their experience on the road with friends via social media, with images of the interior and the surrounding area. The vehicle also takes care of everyday tasks that go beyond the ride itself. For example, the autonomous Audi skysphere concept picks up its passengers with information about their current destination and independently handles parking and charging.

Audi skysphere to be unveiled on its home turf in California

The Audi skysphere concept will make its public debut on August 13, 2021, as part of Monterey Car Week – on the legendary fairways of the Pebble Beach golf course. This means the vehicle’s unveiling in California is taking place more or less on its home turf. This is because the concept car was conceived and designed at the Audi Design Studio in Malibu, just a stone’s throw away from the Pacific Coast Highway, the legendary coastal road that connects the suburbs of Los Angeles with northern California. Studio manager Gael Buzyn and his team are the creative minds behind the project. A legendary classic model from the company’s own history – the Horch 853 roadster – served as the inspiration for the new groundbreaking model. The impressive convertible, which is also around 5.20 meters in length, was not only the definition of modern luxury in the 1930s, but also won the Concours d’Elegance in Pebble Beach in 2009.

But the visual inspiration from its predecessor is limited to the concept car’s dimensions and typical proportions with a rather compact cabin and long front end. A look under the hood of the Horch reveals an imposing straight-eight engine with a displacement of 5 liters. The Audi skysphere, on the other hand, mainly has electric drive components between the front axle and the windshield, such as the charger and the DC/DC converter, plus the actuators and electronic and mechanical components for the adaptive wheelbase. It also features a spacious trunk filled with two golf bags specially designed for the concept car.

The drive system: 465 kW of power

“New technologies like electrification, digitalization, and autonomous driving gave us the opportunity to create an experience that goes way beyond the one that typical roadsters offer today,” said design project manager Gael Buzyn.

An electric motor positioned on the powered rear axle is responsible for delivering power to the wheels of the Audi skysphere. A total of 465 kilowatts of power and 750 Newton meters of torque have an easy time with the roadster, which only weighs around 1,800 kilograms. The weight distribution of around 60 percent on the powered rear axle results in ample traction and acceleration from 0 to 100 km/h in just four seconds, if required.

The Audi skysphere’s battery modules are primarily positioned behind the cabin – an ideal configuration for the vehicle’s center of gravity and agility. Further modules can be found between the seats in the center tunnel of the skysphere interior – another position chosen in favor of vehicle dynamics. The battery’s capacity is expected to be more than 80 kWh, giving the car a range of more than 500 kilometers according to the WLTP standard, at least in the economical GT mode.

The chassis: rear-wheel steering and adaptive air suspension

The vehicle features double wishbone axles in the front and the rear. The upper and lower wishbones are forged or cast from aluminum. Steering takes place via a steer-by-wire system that controls both the front and the rear wheels. Because the system is not mechanically connected to the front axle, the driver can select different steering ratios and steering settings – all at the touch of a button. This allows the steering to be adjusted from extremely direct to comfortable, but also from high self-aligning forces to minimal self-aligning forces, for example when parking. The rear-axle steering and adaptive wheelbase also contribute to the car’s small turning radius.

A long-established Audi chassis technology ensures that the suspension delivers the necessary level of versatility – the latest evolutionary stage of Audi’s adaptive air suspension has been implemented in the concept car and features three independent air chambers to provide a comfortable base suspension. Individual chambers can be deactivated for a more sporty ride with fast acceleration. The result is that the characteristic curve of the spring becomes more progressive, reducing roll and pitch to a minimum. Lowering the body by 10 mm reduces aerodynamic drag – particularly relevant when driving long distances.

The Audi skysphere’s active suspension plays a key role in the versatility of the car’s handling characteristics. When simply coasting along, the individual wheels are selectively raised or lowered to compensate for unevenness and undulations in the road surface – the result of a symbiosis between the navigation system’s digital predictions and the active chassis’ sophisticated control and actuation systems. Mounted on aerodynamically styled 23-inch alloy rims, the 285/30 tires strike a perfect balance between suitability for long-distance trips thanks to minimal rolling resistance and a sporty, active driving style with high longitudinal and lateral acceleration.

Design Sketch

The exterior: reverence without retro

When it comes to their footprint – 5.23 meters in length versus 5.19; a width of 1.85 versus 2.00 meters – it is easy to see the similarity between the legendary Horch 853 convertible and the Audi skysphere. A striking difference, on the other hand, can be found in their height – the legendary Horch, with its iconic design, towered up to 1.77 meters depending on the body shape, while its autonomous descendant, the Audi skysphere, ducks down to the road in Sport mode at 1.23 meters flat, with an optimized center of gravity and aerodynamics. The concept car pays its respects to the classic model without merely remaining a retro imitation.

After all, apart from its dimensions, it’s the lines that make a real difference. With its wide curved and flared wheel arches typical of the brand, the skysphere emphasizes the wide track – a visible indication of its dynamic talents. Viewed from the side, the proportions are impressive with a long hood and – especially at the front – a short overhang. The surfaces of the wheel arches and front hood are organically curved. The rear end was developed in a wind tunnel and combines elements of a speedster and a shooting brake with large glass surfaces in a traditional streamlined design. Two overnight bags designed specifically for the Audi skysphere find space under the glass, and are held in place with straps that are stretched in a crosswise pattern.

The front end – although no longer serving as a radiator grill – clearly features the brand’s typical Singleframe and the three-dimensionally designed, illuminated emblem with the four rings. The entire Singleframe and also the adjacent surfaces on the sides are designed with white LED elements to literally act as a stage for visual effects – both functional effects as well as moving welcome sequences when the vehicle is opened and closed.

Detail

Gentle dimming and a structured, rhythmically pulsating light produce an elegant effect. The daytime running lights in the side front sections, in turn, give the lighting units a resolute, focused “gaze.” If the wheelbase is changed, the LEDs in the front and rear display a specially composed dynamic sequence.

The rear end is also dominated by a digitally controlled LED surface that extends across the entire width of the vehicle. Countless red LEDs are scattered like rubies across the vertical rear surface. Reflections create dynamic lighting and shadow effects when the lighting units are switched on and off.

Upon changing the wheelbase and thus the operating mode from GT to Sport, the light signature also changes and sends a clear indication of the changed character of the Audi skysphere concept, particularly in the area around the Singleframe.

A characteristic feature of the side view are the rocker panels, which seem to protrude into the rear wheel arch – a necessary feature when varying the wheelbase actually pushes it backwards. The rocker panel is attached to the front end of the car, and as it moves, the panel also slides to the rear under the fixed door. In the process, the wheelbase is reduced from the standard size of an A8 L to the significantly more compact size of the curve-compatible Audi RS 5 – 25 centimeters make all the difference. And not just technically, but also visually and, above all, in terms of the driving experience.

There’s no doubt that the Audi skysphere concept has two personalities – a GT and a luxury sports car. The key differences, however, can only be enjoyed in the interior, because here, behind the rear-hinged and wide-opening doors, the Audi skysphere offers highly contrasting experiences.

The interior: two spheres of experience in one

When it comes to the three upcoming concept cars Audi skysphere, Audi grandsphere, and Audi urbansphere, the brand is placing the space that surrounds the passengers (“sphere”) and which becomes an experience for them – the interior – at the center of its designs. This is because all three vehicles are designed for level 4 autonomous driving – meaning that in certain defined road and traffic situations, the driver can delegate complete responsibility to the car and no longer has to intervene.

As a result, control elements such as the steering wheel and pedals can be swiveled into an invisible position and thereby completely removed from the interior. And passengers, including the one in the front left seat, can enjoy a new form of freedom – the freedom to relax in the open air, enjoy the scenery and the wind, or interact with the Internet and the world thanks to the connection with the digital ecosystem in the Audi skysphere.

Free of controls, the interior appears as a light, spacious environment, inspired in many areas by the Art Deco universe. The comfortable seats boast the visual elegance of designer furnishings, yet they fulfill the functions of an car seat in driving mode without any compromises – side support and safety features are part of the package. They are upholstered in sustainably produced microfiber fabric and, thanks to their variable position in the interior, offer the kind of freedom to move and legroom that can otherwise only be experienced when flying first class on an airplane. Environmentally certified eucalyptus wood and synthetically produced imitation leather are other sustainably manufactured materials that contribute to creating an unparalleled experience in the vehicle’s interior.

Should the Audi skysphere concept be used in driver-operated mode, then the interior transforms into an ergonomically perfect driving machine cockpit. Together with the chassis and body, the instrument panel and the monitor panel on the center console also move to the rear. The driver finds all the controls, including the steering wheel and pedals, in the position that best suits them.

Large touch monitor surfaces – 1415 mm wide, 180 mm high – on the dashboard and in the upper area of the center console are used to operate the vehicle and infotainment systems. In Grand Touring mode, this can be used to display content from the Internet, video conferences, or streamed movies. Small touch panels in the doors are used to operate the air conditioning.

A high-quality sound system – befitting of this luxury convertible – delivers concert hall audio quality even when the vehicle is in motion. The speakers are hidden behind the door panels; a few more in the rear interior wall even produce surround sound. The shape of the headrests prevents turbulence and also annoying wind noise.

The vehicle experience: luxury without limits

Audi skysphere, Audi grandsphere, and, coming in 2022, Audi urbansphere are the three concept cars that the brand with the four rings is using to showcase its vision of progressive luxury. In the process, Audi is creating a vehicle experience that goes far beyond the purpose of merely spending time in a car to get from point A to point B, and even far beyond the driving experience itself.

These concept cars feature a new design that ultimately reimagines the interior, the passenger compartment, as the center of the vehicle and no longer subordinates the passenger experience to the requirements of the technology. This is reflected in the variable layout of the interior, the disappearance of the controls, and the sheer expanse of the cabin. In Grand Touring mode, this not only allows both passengers to enjoy a smooth and pleasant journey, but also combines it with new service offerings. These can be used to access a variety of service options related to the current trip – such as designing a spectacular scenic route, as well as restaurant or hotel options.

Customized infotainment options are also available, such as linking the on-board streaming service to music and video providers used at home. And in a further step, Audi also aims to provide personalized and exclusive options for users of its luxury cars in the future – such as concerts, cultural events, or even sporting events that are only available upon special invitation. In this way, a vehicle like the Audi skysphere concept will become a platform for experiences that expand horizons beyond the mere ride in just a few years.

“Porsche Unseen” provides a glimpse of unreleased concept cars

“Porsche Unseen” provides a glimpse of unreleased concept cars

Stuttgart, Germany. Under the title “Porsche Unseen”, Porsche is for the first time publishing design studies from 2005 to 2019 which have until now been kept under lock and key. The sports car manufacturer is showing spectacular visions of 15 different cars. The early studies cover the segments “Spin-offs“, “Little rebels“, “Hyper cars“ and “What’s next?”. In this way, Porsche is offering an exclusive insight into its design process – from the very first drawing to the finished model ready for series production.

“People all over the world love the timeless and innovative design of our sports cars,” says Oliver Blume, Chairman of the Executive Board at Porsche AG. “Visionary concept studies are the foundation of this success: they provide the pool of ideas for the Porsche design of tomorrow, and combine our strong tradition with trailblazing future technologies.”

The previously unpublished design studies are being presented exclusively by the Porsche Newsroom in a series of articles. The 911:Magazine web TV format has also dedicated an episode to selected studies and examines the connection between the studies and the current production models together with Porsche Chief Designer Michael Mauer. For fans of the brand, the book entitled “Porsche Unseen” is released today by the Delius Klasing publishing house. Interested readers are given a detailed look behind the scenes of Style Porsche. A selection of studies will also be on display later for fans to admire live: the Porsche Museum will be integrating the models in the exhibition in 2021.


The design process: from the first drawing to the drivable prototype
The design process starts with a sketch. This is visualised in the next step as a 3D model. As soon as an idea is to be developed further, small models are produced in a scale of 1:3, then followed by hard models in the scale 1:1. “The virtual world is the first step, but you especially have to experience the unusual models in reality in order to understand whether a car has small, large or surprising proportions,” says Michael Mauer, Vice President Style Porsche. In contrast to the development of a production model where several models are always developed with different styling formats, the vision projects, on the other hand, concentrate on a single vision model which serves as a protagonist for the central idea.


“Porsche intentionally has just a single design studio – located in the direct proximity of development,” says Michael Mauer. “Weissach is our epicentre. Instead of opening advanced design studios in the distant metropolises of North America and Asia, our designers come from all over the world to Porsche in Weissach in order to create the latest production sports cars and automotive visions at the heart of the brand. More than 120 designers, experts for interior, exterior, colours and materials, model builders, modellers and study engineers work in the Porsche Design Studio.

The design studies: on a journey of the mind into the future of mobility
“When it comes to the visions we develop, it is not about bringing every car onto the road. Instead, it is more a question of establishing creative space and a relationship with the future,” says Michael Mauer when describing the design process and adds: “There are two possibilities for continuing to develop as a brand: either you improve your products from the present, that is to say step-by-step. However, it is difficult to be really innovative in this process. Or you give free rein to your creativity. The idea is to let your thoughts jump to the day after tomorrow, and to then move back from there to tomorrow.”

Based on this idea, Porsche develops the product and brand identity which characterises and secures the appearance of all models in the long term. The design language for future models develops from the long-term vision. In this process, the higher-level goal is to combine the Porsche design DNA with state-of-the-art vehicle engineering. On the one hand, this secures the innovative capability of future Porsche models and, on the other, also provides an evolutionary reference to the rich history of Porsche. A closer look at some examples:

The Porsche 919 Street (2017; 1:1 clay model) was developed on the basis of the technology used in the Porsche 919 Hybrid, promising to make the exhilarating driving experience of the LMP1 race car available to amateur drivers. Under the outer shell are the carbon monocoque and powerful 900 PS hybrid racing drivetrain that helped the Porsche 919 to achieve numerous victories at Le Mans. The dimensions and wheelbase were also the same as on the race car.

With its spartan, puristic cockpit, the characteristic radiator grilles over the mid engine, red graphic elements and the suggested fins at the rear, the compact Porsche Vision Spyder (2019; 1:1 hard model) clearly calls to mind the Porsche 550-1500 RS Spyder from 1954. At the same time, the study was intended to further develop the design identity of Porsche and provide a pool of ideas for future details – for example, the ultra-modern roll bar.


The Porsche vision “Renndienst” (2018; 1:1 hard model) is the free interpretation of a family-friendly space concept for up to six persons. The design team designed a futuristic “space shuttle“ with exciting proportions. The study shows how the Porsche design DNA with its characteristic surface modelling can be transferred to an unknown vehicle segment for the brand. In the interior, passengers find a comfortable and modular travel cabin. The driver sits in a central driver’s seat. The all-electric drive technology is located in the underbody. As a result, passengers can enjoy an unexpectedly generous space and travel experience combined with Porsche-like flair.

The book “Porsche Unseen” is now available from retailers with the ISBN number 978-3-667-11980-3. The design studies are presented in detail over 328 pages with impressive photos from Stefan Bogner and informative text by Jan Karl Baedeker. It is published by Delius Klasing Verlag and is also available in the Porsche Museum shop.

BUGATTI BOLIDE – WHAT IF …

 Bugatti developed an extreme, track-focused hyper sports car with an unprecedented weight-to-power ratio of only 0.67 kg per PS?

Reduced, raw, authentic. With the technological concept of the Bugatti Bolide1, the French luxury car manufacturer is now providing the answer to the question what if Bugatti built a radically light vehicle around its iconic 8.0-litre W16 engine? The experimental study of the Bugatti Bolide is a track-oriented hyper sports car featuring a W16 engine derived from series production as powertrain combined with a minimal body for maximum downforce. It therefore promises to offer the ultimate Bugatti performance kick.

The idea – what if? An experiment.

“Bugatti stands for the continuous quest for technological innovations – in alignment with the company’s brand values of excellence, courage, dedication. And Bugatti never stands still. We are perpetually aiming for new and exciting goals, and the question that we always keep in mind is: what if?” says Stephan Winkelmann, President of Bugatti.

“We asked ourselves how we could realise the mighty W16 engine as a technical symbol of the brand in its purest form – with solely four wheels, engine, gearbox, steering wheel and, as the only luxury, two seats. Important aspects of our considerations were fine-tuning our iconic powertrain without any limitations as regards the weight-to-power ratio. These considerations resulted in the Bugatti Bolide. An uncompromising experiment, a thoroughbred, a Pur Sang that, in its brute exclusivity, impresses above all with high performance, low weight, and a driving experience in a whole new dimension. Driving the Bolide is like riding on a cannonball.”

The technology – powertrain designed specifically for the racetrack

“The Bolide is the ultimate answer to the question of what if Bugatti built a track-focused hyper sports car that met the FIA’s safety requirements. Designed around the W16 powertrain with the minimum body structure and unbelievable performance data. The result: the smallest possible shell for a breathtaking performance vehicle that allows the W16 to truly come into its own,” explains Stefan Ellrott, member of the Board of Management of Bugatti and Head of Technical Development. “All of Bugatti’s expertise has been condensed into the Bugatti Bolide. It is therefore an innovative information source for future technologies. The Bolide is thus more than just an intellectual exercise.

“In terms of technology and organisation, the Bolide was one of the most ambitious projects of my career,” says Frank Götzke. After playing a crucial role in the development of the Veyron 16.4 and the Chiron, the engineer was also responsible for the technical concept of the Bolide. In only eight months, he created a completely new vehicle around the well-known Bugatti W16 all-wheel powertrain, which was highly modified for the project.

The 8.0-litre W16-cylinder engine with 1,850 PS and 1,850 newton-metres of torque is at its heart. Bugatti has designed the drive specifically for use on the racetrack and has optimised the engine and gearbox in particular for higher engine speeds. Among other things, this includes dethrottling the intake and exhaust system to achieve an even faster, more spontaneous, and extreme response characteristic. The four newly developed turbochargers are fitted with optimised blades in order to build up more boost pressure and power at higher engine speeds. In order to achieve optimum lubrication even under extremely high centrifugal forces, the oil circuit, oil pressure, check valves, baffles, oil tanks, oil reservoirs, and pump design of the dry sump lubrication have been optimised. The weight of the drive system is also significantly reduced at the same time.

Instead of water-to-air intercooling, the Bugatti Bolide has air-to-air intercooling with water pre-cooling for optimal performance on the racetrack. The inflow takes place from the front via one internal and one external air duct on each side of the vehicle. The two water coolers, which are arranged in front of the front axle, provide a more effective radiator system in terms of flow than is customary even in Formula 1. Three air-cooled oil coolers for engine, transmission, and differential with water pre-cooling reduce the temperature even on dynamically demanding race laps. Newly developed and hybrid carbon titanium turbofan radial compressors ventilate and cool the high-performance racing brake system.

1,850 PS and 1,240 kilograms – weight-to-power ratio of 0.67 kg/PS

In order to achieve a dry weight of 1,240 kilograms, all the stops have been pulled out with regard to the materials and production processes used, both in terms of what is currently feasible and what will be possible in the future.

All the screw and fastening elements of the Bolide are made completely out of titanium. In addition, hollow, thin-walled functional components made of an aerospace titanium alloy are used in many places. These originate from a 3D printer and are extremely thin with wall thicknesses of up to 0.5 millimetres. However, they are still very stable with a tensile strength of 1,250 newtons per square millimetre. Hybrid components, such as the 0.5- metre-long auxiliary drive shaft, combine wound high-strength and ultra-stiff carbon fibres with 3D-printed titanium end fittings and can withstand a continuous operating temperature of up to 260 degrees Celsius. In this example, this reduces the weight by around half to 1.5 kilograms and, due to the reduction of the rotating masses, increases the revving ability of the engine at the same time. The forces acting on the front and rear wings are transferred by ultralight but very solid titanium elements. They weigh a mere 600 grams at the front and an astounding 325 grams at the rear.

A worldwide innovation is the morphable outer skin of the intake scoop on the roof, which provides active airflow optimisation. If the vehicle is driven at a slow speed, the surface of the scoop remains smooth. In contrast, a field of bubbles bulges out when driven at fast speeds. This reduces the aerodynamic drag of the scoop by 10 percent and ensures a 17 percent reduction in lift forces. In addition, the flow onto the rear wing is optimised. At 320 km/h, the downforce is at 1,800 kilograms at the rear wing and 800 kilograms at the front wing.

As in Formula 1, the Bolide decelerates with racing brakes with ceramic discs and coatings. The brake callipers weigh only 2.4 kilograms each. The front forged magnesium rims with central lock weigh 7.4 kilograms, while the ones at the rear weigh 8.4 kilograms – with a very wide tyre size of 340 millimetres on the front axle and 400 millimetres on the rear axle (Chiron: 285 mm at the front and 355 mm at the rear). A compressed-air-driven jack system with four rams makes tyre changing easier, a quick refuelling system allows pressure refuelling.

Among other things, a push rod kinematics system with horizontal dampers ensures precise handling. The oil reservoirs are arranged inside the dampers, which improves aerodynamics. Weighing only 100 grams, the push-rods are designed as a thin-walled and flow-optimised titanium lightweight construction with a buckling load of 3.5 tonnes, which corresponds to a dry weight of nearly two Chirons. The welded control arms made of aerospace-grade stainless steel have a tensile strength of 1,200 newtons per square millimetre and are also designed as wing profiles.

Light monocoque made of carbon

The Bugatti team developed a light monocoque made of carbon around the drive. The integral front end flanged to it is also made of high-strength carbon fibres, as are the fully aerodynamically effective underbody and the monocoque itself. The single-fibre tensile strength of the fibres used is 6,750 newtons per square millimetre, the single-fibre stiffness is 350,000 newtons per square millimetre. These represent figures that are only reached in the aerospace industry. The rear frame, designed as a welded steel assembly, offers a maximum tensile strength of 1,200 newtons per square millimetre, despite a wall thickness of only 1 millimetre – this is made possible by the use of high-strength stainless steel, which is otherwise only used in aviation.

With an overall height of only 995 millimetres, the Bugatti Bolide is exactly the same height as the historic Bugatti Type 35, depending on the steering wheel and truncated windscreen, and about 300 millimetres flatter than the Chiron. The wheelbase is 2.75 metres and the width 1.99 metres. Like in an LMP1 racing car, the occupants fold up the doors that are hinged at the front at an angle, sit on a sill that is only 70 millimetres wide, as in a Type 35, and then position their feet in the interior. Thanks to a side wall that is about 150 millimetres lower than that of the Type 35, the procedure is quick and easy – for drivers up to a body height of 2 metres.

Safety is ensured with safety equipment designed in accordance with FIA regulations. These include HANS device compatibility, an automatic fire extinguishing system, a towing device, pressure refuelling with fuel bladder, central locks for the wheels, lightweight polycarbonate windows, and a six-point harness system. The monocoque side floors with integrated carbon coolant pipes are simultaneously designed as side impact structures and structural reinforcement of the monocoque. The driver can see all the relevant data on a motorsport display. For an optimum sitting position, both the pedals and the passenger footrest can be moved by 150 millimetres.

The design – the quintessence of form follows performance

The experimental study of the Bugatti Bolide is also a very special project for Achim Anscheidt, Director of Design at Bugatti. “In my 16 years at Bugatti, I have never worked on a more extreme concept.” The design of the Bolide is radically tailored to the idea of lightweight construction, and the design principle therefore follows on from the overriding goal of achieving a fascinating weight-to-power ratio of 0.67 kilograms per PS.

“It is the very first time that my team had the freedom of creating an absolutely minimalistic design around the W16 engine. The result is the most provocative proportion of a modern Bugatti ever and the distilled quintessence of our Bugatti design ethos that form follows performance,” says Anscheidt. “The Bugatti Bolide, however, is a project more technically driven than shaped by style.”

The stylistic challenge was to transform the unyielding demands of aerodynamics and lightweight construction into an aesthetic that reflects the unique Bugatti DNA, but at the same time illustrates the ambition of an impressive weight-to-power ratio. The overall appearance is dominated by air ducts that are more reminiscent of aerodynamically sophisticated Formula 1 racing cars than classic sports cars. The seemingly filigree and half-open front end is a striking example of the combination of air duct expertise, lightweight construction requirements, and aesthetic dynamics.

The dramatic effect of the overall proportions is made clear by the aerodynamically favourable overall height of only 995 millimetres. The driver’s ultra-sporty seating permits the low-slung shape of an automotive low-flying aircraft. It is therefore not surprising that the appearance of the Bugatti Bolide invokes the so-called X-planes of aviation history and shows a clear X signature from every perspective. It is indirectly reminiscent of the Bell X-1 jet aircraft which was flown by Captain Charles “Chuck” Yeager 1947, the first person to break the sound barrier at Mach 1.06. The Bugatti Bolide “X-periment” has the shape of an aerodynamically optimised, uncompromising racing car and offers ultra-sporty, superlative performance – with no hint of luxury.

As with other Bugatti vehicles, the Bugatti design team also makes use of a colour split in the Bolide. Compared with other models, the share of visible carbon parts is increased by up to 60 percent. Only around 40 percent of the surfaces are painted – in a re-interpretation of the historic French Racing Blue.

“Fifteen years ago, Bugatti succeeded in creating a new segment with the Veyron 16.4: that of the superior hyper sports car. With the Chiron launched in 2016, we systematically developed this segment further. The models bear witness to power and elegance, uniquely combining technology, design, luxury, and quality in a hitherto unknown combination,” explains Anscheidt. “In contrast, the Bugatti Bolide is an absolute rebel. It is clear to see that its only aim is to convey the pure power of the W16 engine in a visually and technically unadulterated form. Reduced, raw, and authentic – like freshly-caught sashimi”.

The DNA – Bugatti Type 35

With the Type 35, Bugatti produced one of the most successful racing cars of all time. The open-top sports car achieved over 2,000 victories between 1924 and 1930. Today, the Type 35 is a legend in racing history. It was inimitable in terms of technology, design, and performance in its time – and still is today. Ettore Bugatti used a double roller bearing and triple ball bearing crank mechanism for the first time. This allowed the engine to rotate at up to 6,000 rpm to move the eight pistons. Two carburettors increased the power to an initial 95 PS. With this engine, the first Type 35 cars were able to reach speeds of over 190 km/h. In the later Type 35 B evolutionary models with a 2.3-litre eight-cylinder engine and compressor, the power output increased to 140 PS, and the Bugatti achieved a top speed of more than 215 km/h.

As well as their incredible power, the engines were primarily renowned for their reliability and endurance. And their lightness. Ettore Bugatti did not compromise when it came to lightweight construction and best possible driveability. He developed special smooth-running wheels to reduce the unsprung masses and, as a result, improve the response of the suspension. The new hollow-bored and forged front axle weighed only 10 kilograms and was nevertheless still stable. A race-ready Bugatti Type 35 weighed only around 750 kilograms. A masterpiece in terms of the weight-to-power ratio.

The verdict – a track-oriented thoroughbred of modern times

The Bugatti Bolide is the unrivalled technological concept of a track-focused Bugatti hyper sports car. The combination of 1,850 PS and 1,240 kilograms dry weight ensures an unbelievable weight-to-power ratio. This puts the Bolide with its W16 engine at the absolute pinnacle in terms of combustion engines used in automotive engineering. “For the first time, we are showing what the W16 engine is really capable of. We have freed the vehicle of all baggage and have illustrated and combined the engine with the lightest possible chassis to create the ultimate Bugatti and to ensure the ultimate driving experience. With the Bolide, we are presenting our interpretation of a Bugatti track car of modern times to Bugatti enthusiasts all over the world and finally make their most fervent wishes come true,” explains Stephan Winkelmann.

Whether the Bugatti Bolide will go into series production, has not been decided yet.
