2019 Porsche 718 Cayman GT4 Clubsport
Three years after the premiere of the first Cayman GT4 Clubsport, Porsche now unveils its successor. The new 718 Cayman GT4 Clubsport represents a consequent further development of the successful model from Weissach.
In developing the new 718 Cayman GT4 Clubsport, the focus was put not only on further improved driveability and faster lap times but also on the sustainable use of raw materials. The 718 Cayman GT4 Clubsport is the first ever production race car to feature body parts made of natural-fibre composite material. The driver and passenger doors and the rear wing are made of an organic fibre mix, sourced primarily from agricultural by-products such as flax or hemp fibres and feature similar properties to carbon fibre in terms of weight and stiffness.
Powering the 718 GT4 Clubsport is a 3.8-litre flat-six engine producing 425 bhp (313 kW). Compared to its predecessor, this represents a 40 bhp increase in performance. The power is transferred to the rear wheels via a Porsche dual-clutch gearbox with six gears and mechanical rear axle differential lock. The lightweight spring-strut front suspension is taken from its big 911 GT3 Cup brother. The impressive racing brake system features steel brake discs all round measuring 380 mm in diameter.
Tipping the scales at 1,320 kg, the 718 Cayman GT4 Clubsport, delivered ex-works with a welded-in safety cage, a racing bucket seat as well as a six-point harness, is a real lightweight.
For the first time, the near-standard mid-engined racer comes in two versions ex-works for global track driving excitement: the “Trackday” model and the “Competition” variant for national and international motor racing. Only the “Competition” edition is offered in the UK.

PorscheThe “Competition” model – which is available in the UK via the Porsche Cars GB Motorsport department – features a raft of details relevant for racing. The shock absorbers can be adjusted in three stages. The safety fuel tank with a capacity of 115 litres is suitable for long-distance events. Thanks to a brake balance system, the balance bias can be infinitely adjusted between the front and rear axle. An integrated air jack system guarantees fast pit stops. The quick-release racing steering wheel adopted from the 911 GT3 R ensures a range of adjustment options for the individual needs of the drivers. An automatic fire extinguishing system adds another safety feature for the racetrack. The 718 Cayman GT4 Clubsport “Competition” is priced at £130,300.00 plus VAT, and is not homologated for road use.
“The new Porsche 718 Cayman GT4 Clubsport possesses significantly more racing genes than its successful predecessor,” says 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 car is available to order immediately and will be delivered to teams and drivers around the world from February.
