4.0This series of the world's biggest motoring show continues as Chris Evans, Matt LeBlanc and Sabine Schmitz buy cheap second-hand cars and head for Venice. The aim? To prove road travel can be more luxurious than taking the train. Elsewhere, Rory Reid heads to New York to sample the all-electric Tesla Model X, while Chris Harris dons his race helmet to drive the most powerful Aston Martin of all time - the fearsome Vulcan. Bear Grylls and Brian Cox are this week's Stars in a Rally Cross Car.
