"Season four of Top Gear goes bigger and faster than ever before as Tanner, Rutledge and Adam continue their quest to test the world's most incredible vehicles in the most outrageous ways. They race from New York to Los Angeles in exotic super cars, attempt an open-water crossing in home-made amphibious cars, test some of the most powerful American cars ever built, and travel alongside the Mississippi in the biggest cars the USA has ever produced. They travel through remote Alaska in home-made convertibles, and a motorbike road trip to Sturgis proves that fewer wheels doesn’t make Adam a better driver. From a high-speed race among a jet boat, rally car and super-car to a review of the brand new Corvette Stingray, this season of Top Gear has got it all and more as our hosts go big or go home in the most action-packed season to date."
"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."
