Located just above the tarmac and positioned low down in the rear is the newly developed water-cooled six-cylinder aluminium engine with four valves per cylinder, VarioCam and a separate engine oil tank.
This high-revving concept promises exceptional power. The engine has a maximum speed of 9,000 rpm. Maximum torque of 440 Nm is available at 6,250 rpm and maximum power output is produced at 8,250 rpm. Particularly lightweight titanium connecting rods facilitate the unit’s impressive rpm capability.
The engine taps into its capacity of 3.8 litres to generate a maximum power output of 350 kW (475 hp). This corresponds to a power output per litre of 92 kW (125 hp). The new 911 GT3 tears acceleration limits asunder: it sprints from 0 to 100 km/h in just 3.5 seconds – 0.6 seconds faster than its predecessor. The 200 km/h mark is also reached 0.9 seconds sooner, after precisely 11.4 seconds.
How is that possible? Thanks to a weight-to-power ratio of only 4.1 kg/kW (3.0 kg/hp), a great deal of fine-tuning and the short transmission ratios of Porsche Doppelkupplung (PDK). These increase torque and acceleration potential in all seven gears. Limits? The new 911 GT3 accepts that only the other side of the 315 km/h mark is beyond its reach.
Direct fuel injection (DFI), fitted in a 911 GT3 model for the first time, makes a decisive contribution to the efficiency of the engine – and its power output. It does it with millisecond precision and a pressure of up to 200 bar. Not only does it provide optimum mixture formation and combustion in the combustion chamber, it reduces the fuel consumption and CO2 emissions.
