A New Heart

Koenigsegg’s first effort at engine development was so successful it saw the company awarded a Guinness World Record. The Koenigsegg CC8S replaced the McLaren F1 as the car with the most powerful production engine in the world.

The next Koenigsegg engine achieved a similar feat when the CCR took the world production car top speed record, again from the McLaren F1. In 2014, we announced the Koenigsegg One:1 with a twin-turbo V8 producing 1,360 hp, enough to make the One:1 the first production car in history with a 1:1 power-to-weight ratio. With 1 megawatt of power, the One:1 was the world’s first Megacar.

That record-breaking tradition continues……

Jesko – the all-new megacar from Koenigsegg – is powered by a newly designed, 1280hp (1600hp on E85 in some markets), twin-turbocharged V8 engine that benefits from significant changes to the Agera engine it replaces.

At the core of the newly designed engine is the world’s lightest V8 crankshaft. Weighing just 12.5 kilos, Koenigsegg’s new flat-plane 180-degree crankshaft allows Jesko to produce more power, with greater efficiency, while achieving a higher 8500rpm rev limit.

The crankshaft is milled by a small manufacturing house located in southern Sweden. It is made to Koenigsegg’s in-house design from a single solid steel billet.

The flat-plane design allows even firing across engine banks and an even more visceral engine sound. Koenigsegg has countered the tendency that flat-plane engines have towards greater vibration by designing new super-light connecting rods and pistons.

The connecting rods were designed by Koenigsegg’s engine architect, Dr. Thomas Johansson. The connecting rods are made from premium Swedish steel. At just 540g – including bolts – they’re as light as previous generations made from titanium, but even stronger.

The piston’s curved face shapes the combustion chamber in such a way so as to reduce peak pressure while maintaining high average pressure. The ceramic coating on the face of the piston prevents hot spots and detonation when the engine runs at maximum power. The piston weighs just 290 grams. Minimal weight is important because Koenigsegg engines have a very long stroke and at 8500rpm, efficiency of movement becomes critical.

Suspension and Steering

The Koenigsegg Jesko was designed as the ultimate road-friendly track car.

As such, we’ve re-engineered what was already a class-leading chassis, equipping it with a host of new technologies to make driving easier around town and much faster on the circuit.

A STRONG CORE

At the core of every Koenigsegg is its carbon fibre monocoque.

Jesko uses an all-new monocoque, designed with the experience of vehicles past but with the requirements of our future customers in mind. The new tub is 40mm longer and 22mm higher, which allows for more legroom, headroom, a more spacious cabin feel and a clearer view through the wrap-around windscreen.

The tub retains its industry-best torsional rigidity, at 65,000 Nm per degree. The Koenigsegg chassis has long proven to be an outstanding base for chassis tuning. It’s also extremely strong and safe, with both the Agera RS and Regera passing crash tests for both EU and USA homologation in recent years.

The monocoque is a carbon fibre and aluminium sandwich construction with integrated fuel tanks, rollover bars and reinforcement using Dyneema – the strongest fibre in the world – an industry first. It is assembled in our factory in Ängelholm, Sweden.

TRIPLEXTENDED

Koenigsegg developed the Triplex Suspension system for the Agera in 2010. A third, horizontal damper added at the rear allowed the car to employ natural physics to combat squat – the tendency for the car’s rear to lower itself under hard acceleration.
Jesko is equipped with a second Triplex unit in the front suspension, extending this capability to the front of the car.

Jesko has over 1,000 kilograms of downforce available. The forward Triplex unit helps to keep the front of the car level, maintaining optimal ride height during high aerodynamic loading without compromising grip and handling at lower speeds.

ACTIVE REAR STEERING

Koenigsegg has equipped Jesko with an adaptive, active rear steering system that increases responsiveness and heightens the senses at both high and low speeds.

Using inputs such as speed, throttle and brake positions, steering and slip angles and other parameters, the steering system can turn the rear wheels up to three degrees in either direction for quicker cornering and increased stability.

At low speeds, the system counter-steers the rear wheels. This gives Jesko a faster turn-in, effectively shortening the turning circle of the car.

At high speeds, the rear wheels turn with the front wheels, a virtual lengthening of the wheelbase. This improves cornering performance on the track and provides increased stability on the road.

Faster cornering, better maneuverability, improved steering feel, more grip and increased confidence.

Interior and Equipment

The new Koenigsegg Jesko is unapologetically designed to be the most capable track-oriented car ever made for the road. It is engineered for prodigious speed – both straight-line and lateral – with total driver control.

That doesn’t mean one has to be uncomfortable, however.

Jesko is equipped with a full suite of creature comforts and a level of convenience more befitting a grand tourer than your typical track weapon.

The simple push of a button on the elegant Koenigsegg remote control operates Autoskin, the pioneering body opening system first shown on the Regera. Minituarised hydraulics that were initially designed to operate aerodynamic systems now engage to open the car’s doors and hoods, allowing true touchless entry.

Koenigsegg’s signature dihedral synchro-helix door hinge has also been re-designed. It now opens slightly outwards and upwards compared to the original. This provides even more room for ingress and egress, and reduces the danger of scraping high curbs. The Autoskin system includes sensors to protect both automated doors from opening where an obstruction is detected.

The interior is swathed in luxury materials – leather, alcantara, carbon fibre, aluminium and glass.

Jesko’s electrically operated seats can be finished in the customer’s choice of leather or alcantara, with an almost endless variety of colour and contrast options. The sport bucket seats are built around a carbon fibre seat shell, resulting in a seat that is both extremely light and comfortable. Controls for seat position and heating are available via the SmartCenter touchscreen. Drivers can find the perfect driving position by matching their seat position with the fully adjustable steering column and pedal box.

SMARTWHEEL ADDED TO KOENIGSEGG’S SMART ARCHITECTURE

Koenigsegg has developed new driver controls using touchscreen technology built into both the new SmartCenter and SmartWheel.

SmartWheel sees two small touchscreens embedded into Jesko’s steering wheel, making a suite of features accessible with just a touch or a swipe. The screens’ default configurations enable functions such as audio control, phone control, ride height control and cruise control. The screens are context sensitive, however, and other options may show or be configured into the system. SmartWheel’s screens feature haptic feedback, allowing ease of use without the need for constant visual connection.

Jesko features a new, racing-inspired and very compact SmartCluster instrument screen. The screen is mounted directly behind the steering wheel and turns as the steering wheel turns. The new 5-inch SmartCluster is extremely compact – it measures just 108mm x 64.8mm – but it contains all the information the driver needs in a neat, logical layout.
