Debut for the newest generation of the Porsche 911 GT3 R

Debut de la nueva generación del Porsche 911 GT3 R

El nuevo Porsche 911 GT3 R se presentará al público en las 24 Horas de Spa-Francorchamps de este año. Comenzando con la Rolex 24 At Daytona, los equipos de clientes de Porsche pueden promocionar el nuevo vehículo de carreras en eventos de automovilismo en todo el mundo que se adhieren a las regulaciones de GT3. El vehículo se basa en el último 911 de la generación 992. En comparación con su predecesor, el nuevo 911 GT3 R cuenta con un motor más grande que produce hasta 565 CV (416 kW), un rendimiento aerodinámico más constante y un equilibrio del vehículo optimizado.

Con la última generación del 911 GT3 R, Porsche presenta un nuevo auto de carreras para clientes. El nuevo retador de la serie GT3 en todo el mundo se basa en la actual generación 992 de la icónica plataforma 911 y estará listo para competir a principios de la temporada 2023. El desarrollo comenzó en 2019. Se dio prioridad a mejorar aún más la capacidad de conducción para los conductores con varios conjuntos de habilidades, así como a aprovechar mayores reservas de rendimiento para diferentes clasificaciones de Balance of Performance (BoP). Otro enfoque fue optimizar el manejo del auto de carrera para los equipos y reducir los costos de funcionamiento. Porsche Motorsport ahora ofrece el nuevo 911 GT3 R a los clientes norteamericanos a un precio de $567,210 y extras opcionales. En los Estados Unidos y Canadá, el nuevo corredor solo está disponible a través de Porsche Motorsport North America.

“En América del Norte, GT3 es la categoría superior de las carreras de GT, como pronto lo será en todo el mundo”, comentó Volker Holzmeyer, presidente y director ejecutivo de Porsche Motorsport North America. “Esto hizo que la nueva generación del 911 GT3 R fuera especialmente importante para nuestro mercado. Su desarrollo, que incorpora no solo las lecciones aprendidas de la generación anterior del GT3 R, sino también del monomarca de la Copa GT3 y del 911 RSR, ha hecho que este coche sea muy atractivo para los equipos de nuestros clientes. La capacidad de conducción es muy importante para la amplia gama de conductores que tenemos compitiendo aquí y ese fue el enfoque del modelo 992 911 GT3 R. Ya hemos tenido un gran interés en el automóvil y estamos ansiosos por verlo girar por primera vez. aquí pronto. Después de que la clase GT3 fuera anunciada como una categoría profesional en el Campeonato IMSA WeatherTech SportsCar de América del Norte, el Campeonato Mundial de Resistencia (WEC) de la FIA hará lo mismo. A partir de 2024, los autos de carreras GT3 como el nuevo 911 GT3 R podrán participar en las 24 Horas de Le Mans por primera vez.

“Dimos en el blanco con el predecesor enormemente exitoso. En consecuencia, el listón para su sucesor es alto”, enfatiza Sebastian Golz, Gerente de Proyecto 911 GT3 R en Porsche Motorsport. “Nuestra tarea consistía menos en hacer que el nuevo 911 GT3 R fuera aún más rápido: la clasificación dentro de las ventanas de rendimiento establecidas por el BoP anula rápidamente esta ventaja. Para nosotros, se trataba principalmente de que nuestros clientes pudieran conducir el auto de carreras rápido durante más tiempo. Esto requiere durabilidad y es por eso que nos enfocamos principalmente en mejorar la capacidad de conducción. Esto se refleja en la banda de revoluciones utilizable más amplia del nuevo motor de 4.2 litros, una aerodinámica más estable y constante y menores cargas en los neumáticos traseros, lo que permite que su potencial dure más tiempo”.

Motor basado en el 911 generación 992

En el núcleo del nuevo auto de carreras se encuentra el motor casi estándar basado en el motor 911 de la generación 992. Como en el modelo anterior, se trata de un motor bóxer de seis cilindros refrigerado por agua con tecnología de cuatro válvulas e inyección directa de gasolina. La principal novedad es el desplazamiento. Al igual que el 911 RSR, la capacidad del nuevo 911 GT3 R ha aumentado un cinco por ciento, de 3.997 a 4.194 cc. Esto ha aumentado la potencia máxima del motor a alrededor de 565 HP (416 kW). Sin embargo, lo que es más importante, Porsche ha optimizado la curva de par y potencia en todo el rango de revoluciones. En consecuencia, el nuevo seis cilindros y 4,2 litros se adapta mejor a una gama más amplia de experiencias de conducción.

El seis cilindros de altas revoluciones continúa sin turboalimentación y se sienta en la posición trasera clásica, mejorando así la tracción y el frenado. Sin embargo, se ha inclinado hacia adelante 5,5 grados, creando más espacio para el difusor debajo de la carrocería. Los componentes auxiliares, como el alternador y el compresor del aire acondicionado, se movieron significativamente hacia adelante y hacia abajo en un espacio frente al motor y la caja de cambios, lo que tiene un efecto positivo en el equilibrio de peso del 911 GT3 R. El concurso secuencial de seis velocidades La caja de cambios de malla se deriva del actual auto de carreras 911 GT3 Cup. Las paletas de cambio controlan un actuador de tambor de cambio electrónico que permite cambios de marcha particularmente rápidos y precisos.

Suspensión modificada en muchos detalles.

La suspensión del nuevo 911 GT3 R (muchos detalles de la cual se han modificado) favorece la facilidad de conducción, permite una dirección más precisa, garantiza un menor desgaste de los neumáticos traseros y reduce el tiempo dedicado a los cambios de configuración. Para ello, se tomaron numerosos componentes y soluciones técnicas del 911 RSR. En el eje delantero, un diseño de doble horquilla de última generación controla las ruedas. El eje trasero luce un diseño multibrazo. Los amortiguadores KW se mejoraron aún más y ofrecen cinco configuraciones de ajuste. Las modificaciones de configuración se realizan con las llamadas cuñas. Estas placas permiten ajustes de precisión sin necesidad de volver a alinear la suspensión después, lo que requiere mucho tiempo.

 

La posición optimizada de los puntos de pivote centrales en el eje delantero libera espacio para el concepto aerodinámico de “carrera bajo el suelo”. Al igual que en el 911 RSR, esta parte inferior de la carrocería elevada permite un flujo de aire limpio hacia el difusor trasero y reduce la sensibilidad de cabeceo del coche de carreras, es decir, una gran inclinación al frenar. Las ruedas traseras se han movido más hacia atrás, lo que amplía la distancia entre ejes de 2459 a 2507 milímetros (8,0 pies a 8,22 pies). Esto también reduce la carga sobre los neumáticos traseros y mejora la consistencia del rendimiento de los neumáticos en períodos más largos.

Pinzas de freno de competición del especialista AP

Además de las pinzas de freno de carreras monobloque de aluminio, los discos de freno del nuevo 911 GT3 R ahora también son suministrados por la empresa especializada AP. Los discos delanteros de acero ranurados y ventilados internamente miden 390 mm (15,35 pulgadas) de diámetro y son activados por seis pistones. En la parte trasera se montan pinzas de cuatro pistones y discos de 370 mm (14,56 pulgadas). Una sofisticada aplicación de software para el ABS de carreras de quinta generación reduce el desgaste de los neumáticos y los frenos. El sistema de control de tracción de Porsche también recibió un mayor desarrollo.

El nuevo 911 GT3 R es el segundo coche de carreras de Porsche Motorsport basado en el modelo actual 992 911 después del 911 GT3 Cup. Su carrocería liviana con un diseño inteligente compuesto de aluminio y acero se basa en el modelo de producción, aunque con importantes modificaciones para su uso en el 911 GT3 R. Casi todos los paneles de la carrocería están hechos de fibra de carbono liviana, incluidas las tapas delantera y trasera, puertas, laterales paneles, alerón trasero y techo. Los pasos de rueda están hechos de fibras de aramida.

Cuerpo ligero con un diseño compuesto de aluminio y acero

En un vehículo como el nuevo 911 GT3 R, la funcionalidad es clave. Sin embargo, Grant Larson de Style Porsche volvió a tener éxito en la creación de formas particularmente impresionantes y armoniosas. Acentúan la herencia del Porsche 911 y la combinan con una eficiencia sofisticada. En particular, esto se refleja en la aerodinámica. Los puntos clave incluyen una parte inferior elevada por delante del eje delantero, por primera vez junto con una bandeja inferior lisa y un difusor trasero. Esta combinación mejora la carga aerodinámica sin un aumento significativo en la resistencia. El alerón trasero ahora cuenta con una montura de cuello de cisne. Esto asegura un flujo de aire limpio debajo del ala y, por lo tanto, mejora la eficiencia aerodinámica del componente.

El interior del nuevo automóvil continúa con el tema de la eficiencia y la evolución. El asiento se ha movido más cerca del centro del automóvil. Esto permitió a Porsche adaptar de manera óptima la posición más ergonómica del asiento a la jaula antivuelco mejorada y a los nuevos mandatos de protección contra impactos laterales de la FIA. Al igual que en el predecesor, el volante y los pedales se pueden ajustar longitudinalmente para adaptarse al conductor manteniendo un asiento fijo. Los especialistas de Porsche volvieron a examinar de cerca el arnés de seis puntos. Las lengüetas ahora se deslizan aún más rápido en el cierre a través de rampas especiales, ahorrando alrededor de un segundo durante las paradas en boxes para los cambios de conductor. El diseño del volante también recibió más mejoras en el modelo anterior. Incorpora elementos que han demostrado su eficacia en los coches de carreras 911 GT3 Cup y 911 RSR de última generación. La pantalla de 10,3 pulgadas, por ejemplo,

Los faros LED de alto rendimiento del 911 GT3 R se basan en la tecnología de colimador, que Porsche desarrolló para el nuevo prototipo IMSA GTP y WEC LMDh 963, entre otros. Este dispositivo funciona como una lupa, solo que al revés. Ilumina un área particularmente grande de la pista de carreras y es una mejora significativa con respecto al modelo anterior, que había sido considerado líder de su clase.

Debut for the newest generation of the Porsche 911 GT3 R

Debut for the newest generation of the Porsche 911 GT3 R

The new Porsche 911 GT3 R will be unveiled to the public at this year’s 24 Hours of Spa-Francorchamps. Beginning with the Rolex 24 At Daytona, Porsche customer teams can campaign the new racing vehicle in worldwide motorsport events that adhere to the GT3 regulations. The vehicle is based on the latest 992-generation 911. Compared to its predecessor, the new 911 GT3 R features a larger engine producing up to 565 HP (416 kW), a more constant aerodynamic performance and an optimized vehicle balance.

With the latest generation of the 911 GT3 R, Porsche unveils a new customer racing car. The new challenger for GT3 series around the world is based on the current 992 generation of the iconic 911 platform and will be ready to race at the beginning of the 2023 season. Development began in 2019. Priority was given to further improving the drivability for drivers with various skillsets, as well as tapping larger performance reserves for different Balance of Performance (BoP) classifications. Another focus was on streamlining the handling of the race car for the teams and reducing the running costs. Porsche Motorsport now offers the new 911 GT3 R to North American customers at a price of $567,210 and optional extras. In the United States and Canada, the new racer is only available through Porsche Motorsport North America.

“In North America, GT3 is the top category of GT racing, as it soon will be around the world,” commented Volker Holzmeyer, president and CEO of Porsche Motorsport North America. “This made the new generation of the 911 GT3 R especially important to our market. Its development, which incorporates not only lessons learned from the previous generation GT3 R but also from the GT3 Cup one-make car as well as the 911 RSR, has made this car very appealing to our customer teams. Drivability is remarkably important to the wide range of drivers that we have competing here and that was a focus of the type 992 911 GT3 R. We have already had overwhelming interest in the car, and we are looking forward to seeing it turn its first wheel here soon.” After the GT3 class was announced as a professional category in the North American IMSA WeatherTech SportsCar Championship, the FIA World Endurance Championship (WEC) will follow suit. Beginning in 2024, GT3 racing cars such as the new 911 GT3 R will be eligible to take part in the 24 Hours of Le Mans for the first time.

“We hit the bull’s eye with the enormously successful predecessor. Accordingly, the bar for its successor is high,” emphasizes Sebastian Golz, 911 GT3 R Project Manager at Porsche Motorsport. “Our task was less about making the new 911 GT3 R even faster – the classification within performance windows set by the BoP quickly cancels out this advantage. For us, it was primarily about our customers being able to drive the racing car fast for longer. This requires durability and that’s why we focused predominantly on improved drivability. This is reflected in the new 4.2-liter engine’s broader usable rev band, more stable and constant aerodynamics and lower loads on the rear tires, which allow their potential to last longer.”

Engine based on the 911 generation 992

At the core of the new racing car is the near-standard engine based on the 992-generation 911 powerplant. Like in the previous model, it is a water-cooled flat-six engine with four-valve technology and direct fuel injection. The main new development is the displacement. Like the 911 RSR, the capacity of the new 911 GT3 R has increased by a five percent from 3,997 to 4,194 cc. This has boosted the engine’s peak output to around 565 HP (416 kW). More importantly, however, Porsche has optimized the torque and power curve across the entire rev range. Consequently, the new 4.2-liter six-cylinder is better suited for a wider range of driver experience.

The high-revving six-cylinder continues without turbocharging and sits in the classic rear position, thus enhancing traction and braking. However, it has been tilted forward by 5.5 degrees, creating more space for the underbody diffuser. Auxiliary components such as the alternator and the air conditioning compressor were moved significantly forward and further down into a space in front of the engine and gearbox, which has a positive effect on the weight balance of the 911 GT3 R. The sequential six-speed contest-mesh gearbox is derived from the current 911 GT3 Cup race car. Shift paddles control an electronic shift drum actuator that enables particularly rapid and precise gear changes.

Suspension modified in many details

The new 911 GT3 R’s suspension – many details of which have been modified – supports driveability, allows more precise steering, ensures less wear on the rear tyres and reduces the time spent on set-up changes. For this, numerous components and technical solutions were taken from the 911 RSR. At the front axle, a state-of-the-art double wishbone layout controls the wheels. The rear axle sports a multi-link design. The KW shock absorbers were further improved and offer five adjustment settings. Set-up modifications are done with so-called shims. These plates enable precision adjustments without the need for the time-consuming re-alignment of the suspension afterward.

The optimized positioning of the central pivot points at the front axle frees space for the aerodynamic “race underfloor” concept. Like in the 911 RSR, this elevated underbody allows for a clean flow of air to the rear diffuser and reduces the pitch sensitivity of the racing car – i.e. a high rake under braking. The rear wheels have been moved further back, which extends the wheelbase from 2,459 to 2,507 millimeters (8.0 feet to 8.22 feet). This also reduces the load on the rear tires and improves the consistency of the tires’ performance over longer stints.

Racing brake callipers by the specialist AP

In addition to the aluminum monobloc racing brake calipers, the brake discs on the new 911 GT3 R are now also supplied by the specialist company AP. The internally vented and slotted front steel discs measure 390 mm (15.35 inches) in diameter and are activated by six pistons. Fitted at the rear are four-piston calipers and discs measuring 370 mm (14.56 inches). A sophisticated software application for the fifth-generation racing ABS reduces wear on the tires and brakes. Porsche’s traction control system also received a further development.

The new 911 GT3 R is the second racing car from Porsche Motorsport to be based on the current type 992 911 after the 911 GT3 Cup. Its lightweight body with an intelligent aluminum-steel composite design draws on the production model, albeit with major modifications for use in the 911 GT3 R. Almost all body panels are made of lightweight carbon fiber, including the front and rear lids, doors, side panels, rear wing and roof. The wheel arches are made of aramid fibers.

Lightweight body with an aluminium-steel composite design

In a vehicle like the new 911 GT3 R, functionality is key. Nevertheless, Grant Larson from Style Porsche again succeeded in creating particularly stunning and harmonious shapes. They accentuate the heritage of the Porsche 911 and blend it with sophisticated efficiency. Most notably, this is reflected in the aerodynamics. The key points include an elevated underbody ahead of the front axle, for the first time in conjunction with a smooth undertray, and a rear diffuser. This combination improves downforce without a significant increase in drag. The rear wing now features a swan-neck mount. This ensures clean airflow under the wing and thus improves the aerodynamic efficiency of the component

The interior of the new car continues the theme of efficiency and evolution. The seat has moved closer to the center of the car. This enabled Porsche to optimally adapt the more ergonomic seat position to the improved roll cage and the newly developed FIA side impact protection mandates. Like in the predecessor, the steering wheel and pedals can be adjusted longitudinally to suit the driver while maintaining a fixed seat mount. Porsche specialists took another close look at the six-point harness. The tongues now slide even faster into the clasp via special ramps – saving about a second during pit stops for driver changes. The steering wheel design also received further upgrades on the previous model. It incorporates elements that have proven themselves in the latest generation 911 GT3 Cup and 911 RSR race cars. The 10.3-inch display, for example, comes from the successful one-make cup racer, with the multi-switch concept adopted from the Le Mans class winner.

The high-performance LED headlights on the 911 GT3 R rely on collimator technology, which Porsche developed for the new IMSA GTP and WEC LMDh 963 prototype, among others. This device works like a magnifying glass, only in reverse. It illuminates a particularly large area of the race track and is a significant improvement on the previous model, which had been regarded as the class leader.Detailed information on the new 911 GT3 R is available on the Porsche website at this link.

However, it has been tilted forward by 5.5 degrees, creating more space for the underbody diffuser. Auxiliary components such as the alternator and the air conditioning compressor were moved significantly forward and further down into a space in front of the engine and gearbox, which has a positive effect on the weight balance of the 911 GT3 R. The sequential six-speed contest-mesh gearbox is derived from the current 911 GT3 Cup race car. Shift paddles control an electronic shift drum actuator that enables particularly rapid and precise gear changes.

Suspension modified in many details

The new 911 GT3 R’s suspension – many details of which have been modified – supports driveability, allows more precise steering, ensures less wear on the rear tyres and reduces the time spent on set-up changes. For this, numerous components and technical solutions were taken from the 911 RSR. At the front axle, a state-of-the-art double wishbone layout controls the wheels. The rear axle sports a multi-link design. The KW shock absorbers were further improved and offer five adjustment settings. Set-up modifications are done with so-called shims. These plates enable precision adjustments without the need for the time-consuming re-alignment of the suspension afterward.

The optimized positioning of the central pivot points at the front axle frees space for the aerodynamic “race underfloor” concept. Like in the 911 RSR, this elevated underbody allows for a clean flow of air to the rear diffuser and reduces the pitch sensitivity of the racing car – i.e. a high rake under braking. The rear wheels have been moved further back, which extends the wheelbase from 2,459 to 2,507 millimeters (8.0 feet to 8.22 feet). This also reduces the load on the rear tires and improves the consistency of the tires’ performance over longer stints.

Racing brake callipers by the specialist AP

In addition to the aluminum monobloc racing brake calipers, the brake discs on the new 911 GT3 R are now also supplied by the specialist company AP. The internally vented and slotted front steel discs measure 390 mm (15.35 inches) in diameter and are activated by six pistons. Fitted at the rear are four-piston calipers and discs measuring 370 mm (14.56 inches). A sophisticated software application for the fifth-generation racing ABS reduces wear on the tires and brakes. Porsche’s traction control system also received a further development.

The new 911 GT3 R is the second racing car from Porsche Motorsport to be based on the current type 992 911 after the 911 GT3 Cup. Its lightweight body with an intelligent aluminum-steel composite design draws on the production model, albeit with major modifications for use in the 911 GT3 R. Almost all body panels are made of lightweight carbon fiber, including the front and rear lids, doors, side panels, rear wing and roof. The wheel arches are made of aramid fibers.

Lightweight body with an aluminium-steel composite design

In a vehicle like the new 911 GT3 R, functionality is key. Nevertheless, Grant Larson from Style Porsche again succeeded in creating particularly stunning and harmonious shapes. They accentuate the heritage of the Porsche 911 and blend it with sophisticated efficiency. Most notably, this is reflected in the aerodynamics. The key points include an elevated underbody ahead of the front axle, for the first time in conjunction with a smooth undertray, and a rear diffuser. This combination improves downforce without a significant increase in drag. The rear wing now features a swan-neck mount. This ensures clean airflow under the wing and thus improves the aerodynamic efficiency of the component

The interior of the new car continues the theme of efficiency and evolution. The seat has moved closer to the center of the car. This enabled Porsche to optimally adapt the more ergonomic seat position to the improved roll cage and the newly developed FIA side impact protection mandates. Like in the predecessor, the steering wheel and pedals can be adjusted longitudinally to suit the driver while maintaining a fixed seat mount. Porsche specialists took another close look at the six-point harness. The tongues now slide even faster into the clasp via special ramps – saving about a second during pit stops for driver changes. The steering wheel design also received further upgrades on the previous model. It incorporates elements that have proven themselves in the latest generation 911 GT3 Cup and 911 RSR race cars. The 10.3-inch display, for example, comes from the successful one-make cup racer, with the multi-switch concept adopted from the Le Mans class winner.

The high-performance LED headlights on the 911 GT3 R rely on collimator technology, which Porsche developed for the new IMSA GTP and WEC LMDh 963 prototype, among others. This device works like a magnifying glass, only in reverse. It illuminates a particularly large area of the race track and is a significant improvement on the previous model, which had been regarded as the class leader.Detailed information on the new 911 GT3 R is available on the Porsche website at this link.
