Porsche 718 Cayman GT4 RS Clubsport
Porsche has revealed the new 718 Cayman GT4 RS Clubsport at the 2021 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. The most significant change is the 4.0 litre six-cylinder boxer engine. 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. The standard 7-speed dual-clutch transmission (PDK) fitted to the car now uses all seven forward gears, rather than six. 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. The homologated vehicle is track-ready ex factory and can be used in SRO racing series around the world without further modifications. The starting price of the vehicle is 196.000 Euro (229.000 Dollar), not including specific tax.
«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. A total of 421 units were built prior to 2018. The next generation model, which was based on the 718 Cayman GT4, debuted in 2019. It was also an extremely success car, with around 500 units produced to date. One of the reasons for the strong demand for these vehicles is due to the low running costs. The use of well-proven series production technology combined with racing-specific components significantly reduces the costs for customer teams.
The Porsche 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. The new engine revs up to 9,000 rpm. It develops 465 newton metres (Nm) at 6,000 rpm instead of the previous 425 Nm at 6,600 rpm. The result is a much wider usable speed band, which makes driving the car much easier for pro-racers and amateur drivers alike.
Modifications to the chassis have also improved the handling of the Porsche 718 Cayman GT4 RS Clubsport. The damper technology has been revised from the ground up in order to achieve an optimised vehicle responsiveness and a further improvement in body control. This has had a significant impact on the overall performance of the vehicle and handling. Upgrades include the use of two-way adjustable shock absorbers with improved characteristics, in addition to adjustable sword-type anti-roll bars front and rear. Vehicle height, camber and toe are also adjustable. Furthermore, three different spring rates for front and rear axle are now available. Special NACA ducts in the bonnet are designed to direct the air flow more efficiently to the large racing braking system fitted with 380 millimetre steel brake discs. The Porsche Stability Management System (PSM) is designed specifically for motorsports and includes a switch for traction control (TC), ABS and an updated stability control system.
Excellent aerodynamics ensure that the precise and controllable handling of the 718 Cayman GT4 RS Clubsport remains well-balanced even in fast curves. Front dive planes and an extended front spoiler lip increase downforce at the front axle. 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 swan neck rear wing has now been given a 20 millimetre long Gurney flap and an adjustment range extended by two additional stages.
