The Porsche 911 GT3 RSR has been updated for 2009. From the outside, you’ll notice the larger air outlets on nose, which feed air into the radiators. On the rear you have a rear wing with a wider adjustment range. The brakes and wiring harness have also been “weight-optimised” (lightened) to improve handling.
The engine bay has gone through some big changes. For one, the 3.8 litre boxer-6 engine is now 4.0 litres, thanks to an increased stroke of 80.4mm compared to 76.4mm in the previous car. Peak engine power is now actually lower, putting out 450hp at 7,800rpm compared to the old car’s 465hp at 8,000rpm. The rev limiter is fixed at 9,000rpm although the engine has a maximum speed of 9,400rpm. Peak torque remains the same, with 430 Newton meters achieved at 7,250rpm. Porsche says the engine now makes more power at low revs, so for each RPM range the new GT3 RSR actually puts out more power despite the peak numbers getting a slight drop.
The interior has a new multi-function display located above the dashboard which can indicate optimum shift timing. The car is quite programmable, for example even the blinking frequency of the lights in the front apron can be infinitely adjustable to help pit crew recognise their car when it rolls in during a night race. For easier pit crew work, the new RSR also features an air-jack system. The oil filler has been moved to the rear lid, which provides for easier access.
