(from Porsche Press
Release) Debut for the 2011 version of the world’s most
successful GT race car
Stuttgart. The Porsche 911 GT3 RSR takes off into the new motorsport
season with extensive modifications. The 2011 version of the world’s
most successful GT race car celebrated its international premiere at
the “Night of Champions” party held at the R&D Centre in Weissach to
mark the end of the motorsport season. Priority in the further
development of the GT3 RSR was given to the newly designed
aerodynamics at the front and rear, changes to the suspension
kinematics and to the engine.
The 4.0-litre, six-cylinder boxer engine now delivers 455 hp (335
kW) at 7,800 revs, five horsepower more than its predecessor. The
power increase results from an engine management system which adapts
even better to different fuel grades, as well as a redesigned
exhaust system and a modified air intake housing. Moreover, the
driveability of the famously efficient engine has undergone further
improvements. Maximum revs remain unchanged at 9,400 rpm.
Clearly visible are the modifications to the front. A new front lip
provides higher downforce at the front axle. The front wheels are
now wider with the rims growing from 11 to 12 inches giving
additional grip and less of an understeering tendency. The position
of the rear wing and the shape of the wing mounting also underwent
optimisation and were adapted to the new rear fairing with
additional air outlet louvers. The rear lid was also redesigned for
optimised air ducting. Like the 911 GT3 Cup and the GT3 R, the RSR
has now been equipped with the LED rear lights taken from the latest
911 road-legal cars.
The 911 GT3 RSR joins the 911 GT3 R and the 911 GT3 Cup as the top
model of Porsche Motorsport’s product range. The successful long
distance racer from Weissach can be ordered now at a price of
410,000 Euro plus country-specific value added tax. All 2011
modifications are available as a kit for GT3 RSR cars from the 2010
