Background
The new Porsche 911 GT3 RSR is ready to race. The top model of Porsche Motorsport's
customer racing vehicles will head into the 2012 season with extensive modifications.
Particularly striking at first glance are the changes to the body: the width
of the new GT3 RSR has grown by 48 millimetres. Built to conform to the A.C.O.
"LM" GTE regulations, the 911 represents the crowning pinnacle of
a range of successful customer sport race cars that are based on the 997 type
911 GT3 RS street sports car.
Powering the new 911 GT3 RSR is a particularly efficient six-cylinder boxer
engine with a four-litre capacity. With a mandatory air-restrictor, it generates
460 hp (338 kW) and drives the 310 millimetre wide rear wheels. The diameter
of the front wheels has increased by 30 mm to now measure 680 millimetres.
The Porsche sequential six-speed gearbox is operated via paddle shifts on
the steering wheel.
The nose and rear panels are adapted to the flared front and rear wheel arches,
as are the door sill and the wheel arch coverings. The aerodynamic concept
is complemented by a new ducting of the intake air. Openings in the rear side
sections, as known from the turbo variants of the Porsche 911, replace the
air scoop on the engine hood, which is very similar to the 911 GT2 RS street
sports car.
The new 911 GT3 RSR can be raced at the Le Mans 24 Hours, the FIA World Endurance
Championship, the Le Mans Series, the American Le Mans Series as well as the
International GT Open and in other series and races.
The new Porsche 911 GT3 RSR will be delivered to customer squads around the
world from January 2012. The selling price is 498,000 Euro plus value added
tax of the respective countries.
