The island nation of Cuba has the most unique car culture in the world. For over 50 years a strict embargo has made it illegal to import cars, parts, and tools from the U.S. This trapped classic American automobiles in a time capsule. In an unprecedented opportunity, the Top Gear hosts visit Cuba to find out how these cars from the golden age of American manufacturing are still on the road. They test and modify three classic American cars, then attempt to make history by competing in a government-sanctioned drag race and become the first Americans to legally race in Cuba in half a century.
