Jay Kay

Jeremy, Richard and James take on three German motoring rivals (including Nurburgring legend Sabine Schmidt) and face their toughest challenge yet – not mentioning the war. James chauffeurs some exceedingly large sumo wrestlers in some exceeding strange Japanese cars, and Richard attacks the test track in Mazda’s remarkable Furai concept car.

Jeremy Clarkson has a high-voltage encounter with the Tesla, a battery-powered super-car and James travels to California to take a look at the hydrogen-powered Honda Clarity. The Star in the Reasonably Priced Car is Tom Jones.

[Season Finale] Matt LeBlanc drives an eight-wheeled rescue vehicle from Russia, Rory Reid turns the world's ugliest car into a luxury yacht and Chris Harris reviews the new Porsche Cayman. Jamiroquai frontman Jay Kay is the studio guest.

Jeremy Clarkson and James May identify, name and shame the world's worst car ever.
