When 500 PS (368 kW) from a high-revving mid-mounted engine meets a purist 1,415 kg kerb weight, it is time for the term ‘driving pleasure‘ to be redefined: the Porsche 718 Cayman GT4 RS is the new flagship model in the 718 family – an uncomp romising driver’s car designed to impress with its lightweight construction, extremely agile chassis set-up, sophisticated aerodynamics and unique soundtrack. Whether it is being driven on narrow, winding mountains roads or closed race tracks, the 718 Cayman GT4 RS is king of the compact mid-engined range. On the Nürburgring Nordschleife, it outperforms its sibling, the 718 Cayman GT4, by more than 23
seconds.
The naturally aspirated flat-six engine, familiar from the 911 GT3 Cup racing car and the 911 GT3 series production model, forms the centrepiece of a sports car that has been designed for maximum driving pleasure. The engine revs as high as 9,000 rpm. Compared to the 718 Cayman GT4, the 718 Cayman GT4 RS has an extra 80 PS (59 kW), resulting in a weight-to-power ratio of 2.83 kg/PS. Maximum torque has been increased from 430 to 450 Nm.
Among the striking features of the new, top-of-the-range 718 are the process air intakes behind the driver and passenger windows. The 718 Cayman normally has small side windows here. The new air intakes improve both the intake airflow and, at the same time, create a thrilling intake noise right next to the occupants' ears. The characteristic air intakes in front of the rear wheels have been retained and are used for engine cooling.
Like every modern RS model, the new 718 GT4 RS is exclusively available with the Porsche seven speed dual clutch transmission (PDK).
The sports low-ratio PDK underpins the incredible acceleration of this mid-engined sports car. The 718 Cayman GT4 RS sprints from 0 to 100 km/h in just 3.4 seconds (GT4 with PDK: 3.9 seconds) and has a top speed of 315 km/h (GT4 with PDK: 302 km/h), which it reaches in seventh gear.
In typical RS style, lightweight construction is a defining element of the new 718 Cayman GT4 RS design. The two-seater weighs only 1,415 kilograms, with a full fuel tank and without a driver as defined by the DIN standard, which is 35 kg less than a PDK-equipped 718 GT4. This weight reduction is achieved thanks to the use of carbon fibre reinforced plastic (CFRP) for components such as the bonnet and front wings. Lightweight carpets also save weight, as does reducing the amount of insulation material. The rear window is made of lightweight glass. Lightweight door panels with textile opening loops and nets are found on the storage compartments.
The new fixed rear wing, its swan-neck attachment and aluminium wing supports, are a distinctive element of the exterior design. This highly efficient wing principle is derived from the Porsche 911 RSR GT racing car and was first adopted in a Porsche series production car with the 911 GT3. In combination with the 30-millimetre-lower ride height compared to the 718 Cayman, the eye-catching vents on the front wheel arches, the aerodynamically optimised underbody panelling with connected rear diffuser, the multi-adjustable front diffuser and the new front spoiler lip with flow-around side blades, in the Performance mode reserved for use on race tracks the GT4 RS generates approximately 25 per cent more downforce than the GT4.
The optional Weissach package takes the dynamic design of the GT4 RS even further. The front luggage-compartment lid, process air intakes, cooling air intakes, airbox cover, exterior mirror upper trims and rear wing have a carbon-weave finish. The titanium tailpipes look similar to the exhaust system on the Porsche 935. The fitted roll cage at the rear is also made of titanium. The upper section of the dashboard is upholstered in Race-Tex material and a large Porsche logo is integrated into the rear window. With the Weissach package 20-inch forged magnesium wheels can be ordered at additional cost instead of the 20-inch forged aluminium wheels.
All of these enhancements compared to the 718 Cayman GT4 make the GT4 RS the most uncompromising and sharpest member of the 718 family. This is particularly evident on the Nürburgring Nordschleife. During the final phase of set-up adjustments, Jörg Bergmeister lapped the 20.832-kilometre track in 7m09.300s and the 20.6 km version in 7m04.511s – 23.6 seconds faster than the 718 Cayman GT4.
The new Porsche 718 Cayman GT4 RS is celebrating its world premiere at the Los Angeles Auto Show and can now be ordered at a base price of 141,338 euros (including 19 per cent VAT). Delivery begins in December. In addition, the GT4 RS is available with the optional Weissach package to further enhance its aerodynamics. The 718 Cayman GT4 RS Clubsport racing version is also celebrating its premiere in Los Angeles, and it will be launched in several national and international racing series starting in 2022.
