Porsche continue to find ways to increase power of the GT3 RS without going the route of turbo chargers. The latest Porsche 911 GT3 RS, unveiled at Geneva, uses an evolution of the 4.0-litre flat six and has the honour of being the most powerful normally aspirated engine to be fitted to a road-going Porsche 911. Power is established at 368kW with 520Nm – 20Nm up from its predecessor – while additional cooling vents have been factored into the engine’s greater requirements.

Despite the extra demand on traction, the GT3 RS remains rear-wheel driven but located in the middle of the drivetrain is a reworked version of the seven-speed dual-clutch transmission with a variable locking differential and torque vectoring.

Designed mostly for the track, the GT3 RS adopts a comprehensive aerodynamic package with prominent front wings and splitter, adjustable rear wing and air ducts that lower the pressure around the axles and reduce lift. Like the 911 Turbo, the GT3 RS is constructed predominantly from aluminium but with a magnesium roof structure. The bonnet and engine cover save weight through carbon reinforced plastic.

With these handful of changes, Porsche believe the GT3 RS will reach 100km/h in 3.3 seconds and 200km/h in 10.9 seconds. The angle of the rear wing determines top speed but Porsche are confident that the latest GT3 RS will reach a speed of 320km/h.
