High-revving engine with 510 PS
The heart of the new Speedster is adopted from the 911 GT3. The naturally aspirated six-cylinder boxer engine with four-litre displacement is a pure GT engine. The peak power of 375 kW (510 PS) is reached at 8,400 rpm, with the maximum engine speed at 9,000 rpm. The engine delivers a maximum torque of 470 newton metres at 6,250 rpm. The new 911 Speedster accelerates from zero to 100 km/h in 4.0 seconds and reaches a top speed of 310 km/h.
Compared 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 (EU6 DG). However, the four-valve engine still manages ten PS more. This is due to improvements to detail such as the high-pressure fuel injectors with optimised spray pattern as well as a modified intake system with individual throttle valves, which enable a more spontaneous response to throttle commands. The newly developed lightweight stainless steel sports exhaust system weighs 10 kilograms less – including the two particulate filters.
Befitting its status as a driver’s car, Porsche only offers the 911 with a manual six-speed sports transmission. It features an auto-blip function which precisely and independently compensates differences in engine speed between the gears when downshifting through automatic throttle blips. Auto-blip can be activated at any time, in other words also independently from the chosen PASM (Porsche Active Suspension Management) variable damping system setting. A mechanical rear differential lock with asymmetric locking action rounds off sporty power transmission.
The GT philosophy behind the new Speedster is also reflected in its chassis. With its sporty rear-axle steering and dynamic engine mounts, the chassis is based on the technology of the 911 GT3 and 911 R. Control systems such as Porsche Torque Vectoring (PTV), Porsche Stability Management (PSM) and PASM with sports tuning and lowering by 25 millimetres have been precisely adapted to the new requirements. The open-top two-seater runs on 20-inch forged Speedster alloy wheels with central locks. The standard equipment includes PCCB brakes (Porsche Ceramic Composite Brake) with internally vented and perforated ceramic composite brake discs.
