The Porsche 718 Cayman GT4 RS has finally been unveiled, with the German marque saying the most hardcore variant of its mid-engined sports car is an “uncompromising driver’s car designed to impress with its lightweight construction, extremely agile chassis set-up, sophisticated aerodynamics and unique soundtrack”.

The first 718 to don the “RS” moniker, the flagship derivative is endowed with Porsche’s atmospheric flat-six engine. The mid-mounted unit, producing 386 kW and 450 Nm of torque, revs to a whopping 9 000 r/min. According to Porsche, these aforementioned figures are enough to propel the Cayman GT4 RS to 100 km/h from standstill in “just” 3.4 seconds. Top speed is rated at 315 km/h. A seven-speed PDK transmission transfers power and torque to the rear axle.

Thanks to its lightweight design, the Cayman GT4 RS weighs “only” 1 415 kg, 35 kg less than the PDK-equipped 718 GT4. To save weight, the RS-badged two-seater has been equipped with myriad carbon fibre-reinforced plastic components. These items can be found on the bonnet and front wings. Lightweight carpets also reduce weight, as does the deletion of insulation material. The rear window, meanwhile, is made from lightweight glass. 

For enhanced downforce (“approximately” 25 per cent more than the standard 718 GT4), the Cayman GT4 RS is equipped with a “highly efficient” fixed rear wing, which features a swan-neck attachment, and an array of additional aerodynamic fitment. The RS-badged model also rides 30 mm lower to the ground than its 718 GT4 sibling.
