The hard facts on Porscheís hardest car 911 GT2 RS:

WE GAVE you a glimpse last month, but now we have every detail of Porscheís fastest-ever 911. The big numbers first. Porsche is asking $645,400 for the GT2 RS. Yes, thatís almost double the price of a 911 GT3, and even more than the $610K Ferrari Australia charges for its 812 Superfast, replete with 588kW V12. But you canít buy one of those, so letís move on.

Packing a monstrous 515kW and 750Nm from its twin-turbocharged 3.8-litre flat six, the GT2 RS tips the scales at 1470kg and will accelerate from 0-100km/h in 2.8 seconds before sailing on to a top whack of 340km/h. You know it gets a seven-speed dual-clutch as mandatory; no manual. Rear-wheel steering, carbon-ceramic brake discs and a suitably lairy PSM stability control tune are also standard, along with some serious boots Ė 265/35ZR20 at the front and 325/30ZR21 at the rear.

The outrageous body features front guards, bonnet, wheel housing vents, mirror shells, air intakes on the rear side sections and parts of the rear end made from carbonfibre-reinforced plastic, as are many of the interior components.

The carís centre of gravity is lowered thanks to the lightweight magnesium roof panel.

So yes, itís expensive, even more so if you add the Weissach package for extra lightness and added cool factor. Still, if thereís one thing weíve learned about RS-badged Porsches itís that Ė longer term at least Ė youíre not going to lose your shirt on one. So when you consider what these cars will change hands for and factor that into your calculations, the GT2 RS could be one of Australiaís cheapest cars to run.
