2018 Porsche GT3 Features

The engine of the new 911 GT3 is not meant as a friendly Swabian gesture, but as a throwing down of the gauntlet. To everyday life. To physics. But, above all, to all the other drivers on the racetracks of this world.

Brief for the new engine: naturally aspirated engine from motorsport, low down in the rear, six cylinders, horizontally opposed pistons. A full four liters of displacement. And high performance potential with unadulterated sound.

The new drive unit was developed – where else? – in Flacht. Particularly robust and powerful, it is based on the engine fitted in the 911 GT3 Cup.

The oil supply principle, which uses a separate engine oil tank, and the concept of four valves per cylinder with cam followers and rigid valve train have also been derived directly from motorsport.

From its impressive capacity of 3,996 cm³, the engine draws a maximum power output of 368 kW (500 hp). With Porsche Doppelkupplung (PDK), fitted as standard, the sprint from 0 to 100 km/h takes just 3.4 seconds and top track speed is 318 km/h. With the optional 6-speed GT sports manual transmission*, the time is 3.9 seconds. Top speed? Not reached until 320 km/h.

At Porsche, natural aspiration also means a high-revving concept. The needle in the 911 GT3 doesn’t hit red until 9,000 rpm. Maximum torque is 460 Nm – some 20 Nm more than is offered by the predecessor model. It is available at 6,000 rpm, while maximum power output is achieved at 8,250 rpm.

As far as the efficiency of the engine – and its power output – is concerned, direct fuel injection (DFI) makes a decisive contribution. It does so with millisecond precision and a pressure of up to 200 bar. For optimum mixture formation and combustion in the combustion chamber. And, relative to the engine’s high power output, it helps to achieve favourable fuel consumption and comparatively low CO2 emissions.
