Jeremy Clarkson and James May investigate an increasingly popular type of tall hatchback often referred to as a 'crossover'. After deducing that these cars are designed entirely to appeal to caravanners, the pair pick examples from Mazda and Volkswagen then use them to spend a couple of days living like the kind of person who would buy one. Meanwhile, Richard Hammond is in Italy driving a pair of Lamborghinis, the sensational Aventador Roadster and a 2 million pound, 570 horsepower riot of carbon fibre and space age styling called the Sesto Elemento. Plus, James May is at the test track to drive a modern recreation of the classic Porsche 911 and Aerosmith legend Steven Tyler is the rock star in the Reasonably Priced Car.
