After the road going 991 GT3 and the 997 GT3 R, Porsche now reveals the RSR racing version of the Porsche 911 (991). The 2014 model comes a whole host of upgrades over the previous model, but it is not exactly a looker, which is a shame because the 997 RSR was a properly handsome race car.

The new 911 GT3 RSR is set to compete at the World Endurance Championship (WEC) and the Le Mans 24 Hours. It is powered by a 460 hp, 4.0-litre six-cylinder boxer engine was taken from the predecessor and optimised in detail.

Where this car has the edge over the old model is in terms of aerodynamics, lightness, and weight balance. The car uses carbon fiber in abundance, as the front and rear mudguards, front and rear lids, doors, underbody, wheel arches, rear wing, dashboard and center console are constructed from this light yet strong material. What’s more, all windows are made of particularly thin and light polycarbonate, and it uses a lithium-ion battery instead of a normal heavy one.

The GT3 RSR has a six-speed racing sequential gearbox operated via steering column-mounted paddle shifters. The new model has a longer wheelbase than its predecessor, and wider tracks, and it also uses a new wishbone front suspension in place of the old McPherson struts.

The driver lineup for the new Porsche 911 GT3 RSR in its European and American adventures include Porsche works drivers Marc Lieb, Richard Lietz, Romain Dumas, Joerg Bergmeister, Patrick Pilet and Timo Bernhard.
