A new version of the GT3 RSR has been announced, with a number of improvements to help it meet new class regulations in GT2.
The previous car saw race victories at the Nürburgring 24 hrs and the American Le Mans Series, so accordingly the new model applies the famous Porsche strategy of subtle, evolved changes rather than a radical redesign.
On the outside, louvres on the nose panel are designed to alter air-ducting for the radiators. At the rear, there are changes to the undercar aerodynamics and a modified rear wing allowing for greater adjustment.
The most significant change is to the flat-six engine, which has been bored out from 3.8 to 4.0-litres. But strangely, due to the changes in class regulation, power output actually drops from the previous incarnation's 465bhp down just over 3% to 450bhp.
However, Porsche has revised the torque curve to make the best of the situation, claiming that compared with its predecessor, the new RSR actually requires less revs to achieve the same levels of power. Peak power now comes at 7,800rpm, with maximum torque unchanged from the last car at 317 lb/ft, available at 7,250rpm.
The race-focussed toys on the car have gotten even more impressive, with the addition of what Porsche call a 'programmable multi-function on-board supply system control device'. What does it do, you ask? It's, er, self-explanatory. Ahem.
You can now also adjust the frequency of the blinking lights on the front apron of the car, to help pit crews identify the car in low visibility conditions, and there's a new air-jack system with an over-pressure valve. The wiring loom has been lightened, and the brakes have been weight-optimised to allow for the various changes.
The revised RSR is not cheap at approximately £413,529 (including VAT) at today's exchange rate, but it is considerably faster than a 3-bed semi in a quiet suburb. And they certainly don't have an oil-refill system with fast-filling function, relocated to the rear lid for convenience...
