This is characterised by a more spontaneous response to throttle commands.Īnother new feature is the ultra-modern thin-wall exhaust gas system: this high-tech component benefits from innovative brazing technology and weighs ten kilograms less thanks to thanks to integrated front silencers and including both particulate filters. This is due to numerous improvements to detail such as the high-pressure injectors with up to 250 bar injection pressure and optimised spray pattern as well as a modified intake system with individual throttle valves. Yet the four-valve engine still manages ten PS more. This guarantees a superior dynamic temperament: The new 911 Speedster accelerates from zero to 100 km/h in 4.0 seconds, covers the quarter mile (400 m) from standstill in 11.9 seconds and reaches a top speed of 310 km/h.Ĭompared with the previous 911 GT3, the engine in the Speedster is fitted with two gasoline particulate filters (GPF) and complies with the emission standard Euro 6d TEMP-EVAP-ISC. With an unladen weight of 1,465 kg, the power-to-weight ratio comes in at an extremely sporty 2.87 kg/PS. The engine delivers the maximum torque – 470 newton metres – at 6,250 rpm. The peak power of 375 kW (510 PS) is reached at 8,400 rpm, with the maximum engine speed at 9,000 rpm. The fact that it is a pure and highly emotive GT engine is proven by its high-revving concept. The heart of the new Speedster is the naturally-aspirated six-cylinder boxer engine with four-litre displacement, adopted from the 911 GT3.
