Part 1: Part 2: "The new episodes of TOP GEAR will take viewers on a wild ride from the backcountry of Arizona into the Grand Canyon, through the Appalachian Trail and even to the Autobahn in Germany for the ultimate high-speed road trip. Adam, Tanner and Rutledge never fail to stand up to every limit, no matter where they are in the world. The guys do everything from testing extreme ways to plow through snow, drag race in muscle cars at the Gatornationals and test how much abuse a car can withstand and still run. Even more exciting are the one-of-a-kind experiences, such as testing the most expensive and aggressive Camaro ever built, and racing the exclusive Bowler EXR-S street legal rally car against an enduro bike in the Scottish Highlands."
