A ride up the famous Goodwood hillclimb with racing legend Rene Arnoux is not something you turn down.

Especially so today, given that he's driving the 320bhp Renault Twin'Run concept. With a V6 in the back and a six-speed sequential racing gearbox, the Twin'Run is never likely to make it into series production. Parts of it, however, like the modular digital dashboard, are said to echo the styling of the next Renault Twingo.

A typically jam-packed Goodwood schedule means we're running late getting down to the start line. A perfect chance for Rene to make up some time by giving it the beans, then. He doesn't need asking twice, and the Twin'Run certainly has plenty of beans to put down.

Down at the start line, we join the queue of supercars waiting to prove themselves on the famous course. Oddly, the Twin'Run's styling doesn't look out of place here, and a few blips of the V6's throttle by Rene quickly halt any rumblings that the Renault's place is anywhere but here.

I'm reminded of my trip to Le Mans a few weeks back, sitting in a traffic jam of rare and powerful exotica. We've got the GTA Spano in front - and as it screams off the line, we edge forward for our turn.
