This fast-paced, stunt-filled motor show tests whether cars, both mundane and extraordinary, live up to their manufacturers' claims. The hosts travel to locations around the world, performing extreme stunts and taking part in some unusual challenges to see what the featured cars are capable of. Celebrity guests also appear on some of the episodes to help test out the vehicles. However, things don't always go as planned, with broken bones and mechanical mishaps sometimes part of the experiments.
