In the first of a series of feature length Specials, Clarkson, Hammond and May take a one time only break from cars and set out on an epic journey across Cambodia and Vietnam…in boats.

But a bizarre challenge propels them to Madagascar where they must tackle the world’s toughest road.

Everyone's favourite trio are back and they're here to answer a very important question: What's going on with French cars? Join Clarkson, Hammond and May as they investigate the wonderfully weird world of French cars on their latest Grand Tour adventure.
