Each episode focuses on a particular group of vehicles, such as best British car and best 1960s muscle car. The celebrities combine their automobile knowledge with their driving skills as they test cars to see which ones they think qualify as the best-of-class. The hosts also offer practical advice that viewers can take away from the episodes.

Leno explores different aspects of automobiles, including the history of iconic brands, testing supercars, checking out the latest innovations, and even offering consumer advice. He also talks with fellow gearheads, including celebrities, to learn about their collections. Leno says cars, to him, are "kinetic artwork" -- rather than being stagnant, it is art that is "rolling down the highway."
