Jeremy Clarkson, Richard Hammond and James May engage in another collection of incredible adventures, assisted by their tame racing driver, The Stig. In this series, the presenters use the Aston Martin Vanquish, SRT Viper and Lexus LFA for an incredible American road trip that takes in Las Vegas, Los Angeles and a race against some fighter planes before ending with a hair raising run to the Mexican border. There’s also one of Top Gear’s epic journeys in which the presenters attempt to find the source of the River Nile using three rather tired estate cars and a sometimes sketchy knowledge of African geography!
