New Cayman GT4 Clubsport Revealed
Porsche has unveiled a successor to its popular 981 Cayman GT4 Clubsport, the new Cayman GT4 Clubsport competition car precedes a forthcoming road car of the same ilk and importantly retains a naturally-aspirated six-cylinder engine. The 3.8-litre engine produces 425hp, a 40hp increase over its forebear, and revs to 7,800rpm – it sends power to its rear wheels through a six-speed PDK dual-clutch gearbox and also boasts a mechanical locking rear differential. The new car has the internal Porsche chassis code ‘982’, though its model code remains ‘718’ – the current Cayman and Boxster road car designation.
The first production racing car ever with body panels made from natural-fibre composites, the new Porsche features doors and a rear wing made of an organic fibre mix sourced primarily from agricultural by-products, such as hemp fibres, the material has similar properties to that of carbon fibre in terms of weight and rigidity. The fixed rear wing has an integrated carbon fibre Gurney flap to maximise aerodynamic balance. Lightweight front suspension has been lifted from the new GT4’s big brother – the 911 GT3 Cup car. Steel brake discs appear on all four corners, these measure 380mm in diameter. Delivered with an FIA certified weld-in roll cage, a Recaro racing bucket seat and six-point harnesses, the GT4 Clubsport majors on lightness, tipping the scales at 1,320kg thanks in part to 9- and 10×18-inch single-piece forged alloy wheels – these accept 25/64-18 and 27/68-18 Michelin slick or wet weather tyres.
Porsche will produce two versions of the new mid-engined racer, a ‘Trackday’ model and a ‘Competition’, the former aimed at drivers wishing to take part in occasional track day usage, the latter variant being tailored for national and international motor racing. Note that only the ‘Competition’ edition will be offered in the UK for the time being. This version features shock absorbers that can be adjusted in three stages. A safety fuel tank with a capacity of 115-litres – making it suitable for long-distance events, a brake balance system allowing the balance bias to be infinitely adjusted between the front and rear axle, an integrated air jack system, a quick-release racing steering wheel (pinched from the 911 GT3 R), and an automatic fire extinguisher system.
The new GT4 Clubsport also features a bonnet and rear deck lid with quick-release fasteners together with an FIA standard roof escape hatch. Inside the dashboard has a Cosworth instrument cluster with integrated data logger, an emergency cut-off switch (both inside and out), and centre console switches for the adjustment of the ABS, ESC and TC systems – PSM (Porsche Stability Management) with ABS, traction Control (TC) and Electronic Stability Control (ESC) are all able to be completely deactivated. For comfort during longer races an air conditioning system has been retained.
“The new Porsche 718 Cayman GT4 Clubsport possesses significantly more racing genes than its successful predecessor,” said Porsche’s head of motorsport, Fritz Enzinger. “The power of the engine has increased considerably. At the same time, we were able to increase the downforce and the cockpit is now even better suited to drivers’ needs. I’m confident that we can build on the excellent sales figures of the predecessor, of which we have delivered 421 cars.”
The 982 Cayman GT4 Clubsport ‘Competition’ is priced at £130,300 (plus VAT) and is available to order now from Porsche Cars GB’s Motorsport department – deliveries to teams and drivers areexpected from February.
