Porsche?s new quickie is Down Under

Porsche will be releasing only 35 of the GT3 RSR globally.

The potent Porsche GT3 RSR has received aerodynamic upgrades for 2008. Only 35 of the thoroughbred coupes are being released globally.

At a price tag of $600,000 a pop, the GT3 RSR is very much at the top of the 911 pecking order.

Some of the upgrades run off the back of Porsche's highly successful RS Spyder program, which was raced to devastating effect in the American Le Mans Series last season under the leviathan Penske Racing organisation.

There are some aerodynamic refinements, a more optimised suspension and a clever new sequential transmission with software passed down from the RS Spyder LMP2 prototypes.

The GT3 RSR has a new front end and is unmistakable with its over-the-top 'flicks' on the front bumper.

Newly designed side air outlets give the car more stability through less drag and better down force.

It is more the scientific improvements that have embellished the RSR as the nerve centre remains the same with the 3.8-litre boxer engine remaining at 342kW of power at a screaming 8000rpm with 430Nm of torque at 7250rpm. The rev limit is set at 9400rpm.

Among other changes the sequential gearbox is said to be considerably lighter than the one it replaces.

The GT3 RSR comes out of the Weissach facility in Germany which also produces the awesome RS Spyder, 911 GT3, 911 GT3 RS, 911 GT3 Cup car and the yet-to-be-released 911 GT2.

Among its more notable exploits on the racetrack the 911 GT3 RSR's resume is headed by a win at the Le Mans 24-hour last year in the GT2 class and in the Nurburgring 24-hour.
