The new Porsche 718 Cayman GT4 RS Clubsport
Porsche has revealed the new 718 Cayman GT4 RS Clubsport at the Los Angeles Auto Show. The mid-engined race car from Weissach is based on the new 718 Cayman GT4 RS road car which has also just been unveiled.
This high-revving powerplant has been taken directly from the 911 GT3 Cup race car and develops 500 PS in the 718 Cayman GT4 RS Clubsport – 75 PS more than the previous GT4 Clubsport model. In addition to many upgraded details, the focus in developing the new 718 Cayman GT4 RS Clubsport was on further improving overall performance. All gears feature shorter ratios than in the previous model. Depending on the track and series-specific regulations, the new 718 Cayman GT4 RS Clubsport can achieve lap times that are over two percent quicker than the previous model.
Faster lap times and further improvement in driveability
We have incorporated our experience of the last three years of running the previous GT4 Clubsport as well as customer wishes into the development of the new car,“ said Michael Dreiser, Manager of Sales and Distribution at Porsche Motorsport. “Faster lap times combined with a further improvement in driveability offer our customers a competitive product for the upcoming racing seasons in GT4 class racing competitions around the world.“ Porsche began offering the Cayman GT4 Clubsport of the 981 generation in 2016, entering into this new customer racing format early with a competitive car.
The 718 Cayman GT4 RS Clubsport continues this tradition and offers a further improvement in terms of its competitiveness. The 500 PS 4.0 litre six-cylinder boxer engine taken directly from the current 911 GT3 Cup racing car is almost 18 per cent more powerful than the 3.8 litre engine that was used in the previous model. Thanks to an optimised air intake, maximum power is achieved at 8,300 rpm – 800 rpm higher than the previous engine.
Excellent aerodynamics ensure precise handling
Wheel arch vents in the wings inspired by the 911 GT3 R and air curtains specifically designed to calm the air turbulence around the front wheels, while the fully enclosed underbody optimises air flow to the diffusor at the rear of the car.
The previous 718 Cayman GT4 Clubsport was the first ever series production race car to use body parts made of renewable natural-fibre composite material. In the case of the new GT4 RS Clubsport, even more extensive use of this material is made in the vehicle as a whole. In addition to the doors and the rear wing, the bonnet, the wings, the aerodynamic components at the front end and the steering wheel are now made of this material. The use of this flax-based fibre as an alternative to carbon fibre composite material can now be tested in motorsports for its use in road cars.
Der 718 Cayman GT4 RS Clubsport is ready for racing
The 718 Cayman GT4 RS Clubsport is equipped to meet all the prerequisites allowing it to compete in racing events directly from the factory. The new safety foam on the driver’s side meets the international requirements of the SRO racing series.
The FT3 safety fuel cell can take up to 115 litres of fuel, making it suitable for endurance racing.
