CHALLENGE: The Race for the Universe

James and Richard go camping with a selection of cabriolets to see which is the best. Naturally they choose the wettest place in Britain, Buttermere in Cumbria. Jeremy drives the Alpha Romeo 147 GTA and the Nissan 350Z and a Klingon, a Darlek, a Cyberman, Ming the Merciless and Darth Vader race each other around the track in a souped-up Honda Civic. Jodie Kidd shows the men how to drive the Liana - properly.

Jeremy Clarkson, Richard Hammond and James May go head-to-head against their opposite numbers from Australian Top Gear in a car-based version of The Ashes. With disciplines including rallying, drifting and an Aussie version of double-decker car racing it's an all-out grudge match that will almost certainly end in tears. Also in the show, Jeremy is on the test track in Ferrari's new 599 GTO and Boris Becker is the Star in a Reasonably Priced Car.
