The Show - Next Episode

On the next show, the presenters take a stroll down Electric Avenue, the latest supercars from the USA and Europe slug it out on the test track, and Frost/Nixon and Damned United star Michael Sheen, pops in for a chat.

Our three unlikely eco-warriors set about saving the planet by building their very own 'green' electric vehicle. Not only do they have to accomplish this without accidentally running a few thousand volts through James May, they also have to contend with the rigours of the new car testing process.

Meanwhile, out on the test track it's the fight of the blue-collar brawler and the Teutonic technocrat as the Corvette ZR1 and Audi's new ten-cylinder R8 go toe-to-toe.
