2015 Porsche 911 991 - total new turbo era

Porsche 911 991-series to go turbo across the range? To combine acceptably low CO2 emissions with the power that its customers desire, Porsche will extend turbocharging to the 911 Carrera (the current model is pictured), always normally aspirated up until now. It is expected that for the “Gen 2” 911 – the mid term engineering update on the 991-series – both the Carrera and Carrera S will receive new turbo engines.

Reports say the present base Carrera engine of 3.4 litres will drop to 2.9, but with forced induction will produce just over 400bhp and around 400lb ft torque – increases of 15 and 40 per cent respectively. The development on the Carrera S looks especially fascinating, as its engine capacity is expected to remain at 3.8 litres, and once turbocharged will take power from around 400bhp to 530bhp and torque from 325lb ft to over 510lb ft.

Neither car will be badged “Turbo”, but precisely where this leaves the actual 911 Turbo, which at the moment is under these figures, is an obvious question. While the “mainstream” 911s become turbocharged (and less CO2 emitting), a future GT3 is likely to retain a normally aspirated engine. But this too is going to need a power increase from its present 468bhp in order to slot into the range logically.
