Top Gear - Season 4

The guys compete over which is the best new police car to replace the Crown Vic in a series of madcap challenges around Detroit, Mich.

Small cars work in the rest of the world but will they ever work here? The guys try to answer the question and travel to Louisiana to take them out of their natural home on the narrow city streets of New Orleans and deep into Cajun Country where they have to hunt and survive alongside the locals. Whoever did the worst in their car suffers the humiliation of having to drive the world s smallest car for a day in their home town.

Could you own a classic car and not know it? The guys each get a car that they think is seriously undervalued and set out to reestablish its reputation before creating a live commercial in San Diego and attempting to make money on it. The two losers have to entertain two celebrities in a crazy race in equally crazy vehicles, and it gets out of control fast.

How far can you get on one tank of gas? The guys find out as they race from Portland, Oregon to San Francisco without being able to fill up. Whoever makes it closest gets the chance to drive the toughest off road machine in the world in a high-octane race in the remote Colorado mountains.

The guys head to rural California and attempt to help a farmer with three of the biggest tractors on the market. It quickly descends into chaos as they try to transport livestock and heavy equipment and complete farm chores. We then review the fastest "tractor" of them all--the new Lamborghini Aventador--and see how its claims stack up in a race against a crop dusting plane.

Do you really need an expensive 4x4 to go off road? The guys don't think so and to prove their point use three classic rental cars and attempt to complete and epic journey on some of the toughest terrain in the country from Monument Valley to Moab.
