Engine 911 GT3

Porsche - Engine

Engine

Located just above the tarmac and positioned low down in the rear is the newly developed water-cooled six-cylinder aluminum 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 325 lb.-ft. is available at 6,250 rpm and maximum power output is produced at 8,250 rpm. Particularly lightweight titanum connecting rods facilitate the unit’s impressive rpm capability.

The engine taps into its capacity of 3.8 liters to generate a maximum power output of 475 horsepower. This corresponds to a power output per liter of 125 hp. The new 911 GT3 tears acceleration limits asunder: it sprints from 0 to 60 mph in just 3.3 seconds – 0.7 seconds faster than its predecessor. The 124 mph 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 6.6 lb/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 195 mph 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 2900 psi. Not only does it provide optimum mixture formation and combustion in the combustion chamber, it helps to reduce CO2 emissions of the new 911 GT3 to values around 16% lower than those of its predecessor.
