Their pure character will appeal to sports car enthusiasts who delight in unadulterated driving pleasure and appreciate a high level of agility and an almost intimate proximity to the centre of power. The perfectly balanced mid-engine concept offers all this. For the first time ever, the 718 Spyder and the 718 Cayman GT4 share a technical base. This includes the newly developed four-litre six-cylinder naturally aspirated engine, together with a six-speed manual transmission. The boxer engine generates 309 kW (420 PS; fuel consumption combined 10.9 l/100 km; CO2 emissions combined 249 g/km) in both models. Whilst the GT4 represents the entry-level GT road model from Porsche, the Spyder lends itself to all kinds of curves. Both rely on highly efficient aerodynamics, a full GT chassis and powerful brakes.


High-revving and highly emotional naturally aspirated engine

At the heart of both models is the new four-litre six-cylinder boxer engine. The naturally aspirated engine is based on the same engine family as the turbo engines in the current 911 Carrera model series. The new high-revving engine generates 309 kW (420 PS) – 35 PS more than in the GT4 predecessor models. The third generation of the Spyder even has 45 PS more. It delivers a maximum torque of 420 newton metres at between 5,000 and 6,800 rpm. The manual transmission sports cars can both break the 300 km/h barrier: the 718 Spyder has a top speed of 301 km/h, whilst the 718 Cayman GT4 can reach 304 km/h. Both models accelerate to 100 km/h in 4.4 seconds from a standing start. The correlated fuel consumption of the mid-engine sports cars is 10.9 l/100 km according to the New European Driving Cycle (NEDC). The fascinating character of this naturally aspirated engine combines a modern gasoline particulate filter emission control system with the linear power delivery and the immediate response of a GT engine. It has a maximum engine speed of 8,000 revolutions. The unparalleled boxer sound remains untouched. New additions include technical highlights such as adaptive cylinder control. In part-load operation, it temporarily interrupts the injection process in one of the two cylinder banks, thus reducing fuel consumption.

Piezo injectors are used for direct fuel injection for the first time ever in a high-revving engine. They split each injection process into up to five individual injections. This supports a complete – and therefore emissions-friendly – combustion process. A variable intake system with two resonance valves ensures optimum gas exchange in the cylinders.


Aerodynamic efficiency: more downforce, the same drag

Among the striking features of the 718 Cayman GT4 is the comprehensively improved aerodynamics concept. It produces up to 50 percent more downforce, without adversely affecting drag – proof of outstand...
