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, 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.
The coupe and convertible set off a fireworks display of technical refinements. The completely redesigned four-liter boxer engine, now 420 hp strong (309 kW; fuel consumption combined 10.9 l/100 km; CO2 emissions 249 g/km), adopts important components from the new 911, including its electronics. The selective cylinder control cuts out three of the six combustion chambers during constant cruising, thereby lowering consumption considerably. Particle filters help comply with current emissions standards.The Spyder in particular ups the ante notably with the chassis, which—like the GT4—is based on many lightweight aluminum components from the 911 GT3 and the Cup race car. Newly developed ultra-high-performance tires ensure even greater grip with special rubber mixtures. And the Porsche Active Suspension Management (PASM) and Porsche Stability Management (PSM) driving dynamics systems are precisely adapted to work in lockstep with the new features. And, as in all GT models from Porsche, they can be completely switched off as well. Optional ceramic brakes reduce the unsprung masses per wheel by up to 4.75 kilograms, or almost 50 percent.
