Two special Top Gear episodes presented by Jeremy Clarkson, Richard Hammond and James May. In 'Polar Special' the Top Gear team set out on their most ambitious and arduous challenge to date - a race starting in Canada and finishing at the North Pole. In 'US Special', with a budget of $1000 dollars, each of the team have to buy a car for an epic road trip, stopping along the way to compete in a series of challenges which range from driving across Alabama without getting shot to preparing and eating road kill whilst camping out for the night.
