Engine 911 GT2 RS

Porsche 911 GT2 RS - Engine


Anyone can be unyielding. But whether they also make an impact depends on one crucial feature: charisma. The ability to lead and be ahead. The performance data of the new 911 GT2 RS show that many will follow in its wake – presumably because they cannot overtake it.

The source of its natural authority: the six-cylinder, twin-turbo boxer engine at the rear, four-valve technology, variable turbine geometry (VTG) with large turbochargers and newly designed charged air system, direct fuel injection (DFI) and VarioCam Plus. And transmission directly above the rear axle.

With a displacement of 3,800 cm³, the engine produces an impressive 515 kW (700 hp) at an rpm of 7,000. Maximum rpm is 7,200, and the maximum torque of 750 Nm is available from just 2,500 rpm. Sustainably unyielding – with sustainable performance.

A quick look at the speedometer. It goes up to 400 km/h. A figure that will bring tears of joy to the eyes of every sports car fan. And also sets the tone for the maximum speed: 340 km/h Vmax. How does the new 911 GT2 RS achieve this? Quickly, of course. It ticks the acceleration from 0 to 100 km/h box after just 2.8 seconds. It reaches the 200-km/h mark after only 8.3 seconds. And after 22.1 seconds, the 300-km/h mark is water under the bridge.

Variable turbine geometry (VTG)

The variable turbine geometry of the twin water-cooled turbochargers arranged in parallel directs the incoming exhaust gas towards the turbine wheel via electronically controlled, moveable vanes in such a way that the ratios of both a ‘small’ and ‘large’ turbocharger can be achieved. VTG therefore largely eliminates the target conflict of a normal turbocharger – and enables optimum aspect ratios to be achieved in every operational state.

At low revs, this results in a high turbine speed and thus a high charge pressure – for increased engine filling efficiency, greater torque and considerably improved performance. The torque curve reaches a higher level much earlier – and then maintains it. At high revs on the other hand, the full potential of a large charger can be utilised by adjusting the vanes – a lower exhaust back pressure for maximum performance. Thanks to the variable turbine geometry, the dynamic build-up of charge pressure produces an improved response.

VarioCam Plus

VarioCam Plus is a 2-in-1 engine concept for adjusting the intake camshafts and switching the lift of the intake valves.

The system differentiates between normal everyday and maximum performance requirements and adapts to the respective conditions. The switching is undertaken imperceptibly by the electronic engine management system. The result: spontaneous acceleration, extremely smooth running and exceptional pulling power.

Expansion intake manifold

Compared to conventional intake manifolds, the expansion intake manifold of the new 911 GT2 RS has a modified geometry: the distributor pipe is longer, with a smaller diameter and the intake pipes are shorter, meaning that the air vibrates differently. Consequently, the mixture in the combustion chamber is cooler – and ignites in a performance-optimised way. Intercoolers additionally enhance this effect.

Instead of more air as in a traditional resonance intake manifold, cooler air therefore ensures improved performance. The result: improved engine efficiency for increased engine performance. And better fuel consumption even under heavy loads at at high revs.


To complement the expansion intake manifold, two large intercoolers at the rear of the vehicle supply the engine with cooled charging air. Under extreme conditions, the newly developed spray system sprays atomised water on the intercooler networks, allowing a thermostable charging air feed.

Maximum output is therefore maintained for longer, even at high exterior temperatures. The tank holds 5 litres of water and is easily accessible in the luggage compartment. A display on the on-board computer shows you when it needs refilling.
