Exploring the topics of danger, food, and accommodation, and visiting everywhere from the Polar Ice caps to the Middle East.
A look at some of the boys' attempts at re-engineering as they get their hands dirty modifying everything from motorbikes that ride on water to a 60 meter bridge, and time to revisit some of James May's hilarious motoring mishaps around the globe.
Revisit some of the boys' races, taking place in alarmingly unsuitable vehicles, in equally unsuitable locations! We also look at some extreme driving - from risking life and limb on Bolivia's Death Road to crossing hippo-infested waters in Botswana.
