USA Supercar Road Trip

S15 E7: The Top Gear boys are once again let loose in the USA, this time for an epic road trip up the east coast. Jeremy Clarkson, Richard Hammond and James May are comparing the Mercedes SLS, the Porsche 911 GT3 RS and the Ferrari 458 Italia. Along the way they undertake a series of challenges culminating in a fight to find the fastest way into New York, all in the name of crowning the world's greatest sports car. There's a round up of car-related Christmas tat and Oscar-winning film director Danny Boyle takes to the track as the star in a Reasonably Priced Car.
