Background
Porsche has unveiled the 2011 911 GT3 RSR at the "Night of Champions"
party in Weissach.
Essentially an evolution of the previous RSR, the updated model features a
new front lip spoiler, wider front wheels (that measure 12J x 18 ET 34), and
an optimized rear wing. Other goodies include a modified rear fascia and LED
taillights that mimic the ones on road-going 911s.
Under the hood, the 4.0-liter six-cylinder produces 455 PS (335 kW / 449 hp)
and 450 Nm (332 lb-ft) of torque. Despite the minor 5 PS (4 kW / 5 hp) increase
in output, the engine boasts a new ECU, a redesigned exhaust, and a modified
air intake.
Currently available for order, the 911 GT3 RSR will be priced from euro410,000
($541,080 / £342,740).
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 season.
