I’ve been watching a lot of racing lately. Not just Nurburgring 24, VLN, Porsche Supercup and Carrera Cup, but Blancpain Endurance and the ALMS series.

Blancpain from Silverstone on Motors TV the other night was interesting. In the wet, the little old 911 GT3 RS racecars were setting respectable times versus the latest McLarens and Mercedes SLS.

It made me wonder: how fast is the GT3 RS road car (sweet GT3 pic above) on a dry, twisty circuit versus the McLaren MP4-12C? Thankfully, my former clients at Autocar magazine have provided the answer in video.

It’s tempting to dismiss a review that starts: “venerable” Porsche 911 versus “dizzying” new McLaren. But this is Steve Sutcliffe, who has more than a clue. The results might surprise you, especially when considering the respective purchase prices: £193,000 approx for the McLaren.
