Walter Rohrl doesn't need an introduction either, but we'll give him one anyway. He's the bloke that used to race those phenomenally fast Audi Sport Quattro S1 rally cars of the eighties. He's also renowned for competing, and winning, classic rally races in scary-old 911s nowadays, too. But making up the largest piece of the hero cake is what he does for a crust; he's the chief test driver at Porsche. He knows how to throw one around. Why are you still reading this anyway, surely you've already jumped straight to the video below?
Need we say more. It's the most powerful 911 to date; the 2010 Porsche 911 GT2 RS. And to give you an idea of what it's made of, here's a video of Walter Rohrl whipping it around a track. 470kW, 3.8-litre, twin turbocharged flat six. Rear-wheel drive. 0-100km/h in 3.5 seconds.
