Test Drive Le Mans is the official game of the internationally famous Le Mans auto race, which dates back to 1923. Players can select from among a series of Le Mans circuit tracks that wind through the Sarthe region of France, and choose from among over 40 cars that reach speeds approaching 200 mph. Also, race fans can compete in GT and prototype classes, and choose from officially licensed racing teams.

Along with distinct engine sounds, the cars also exhibit realistic engine conditions, so that racers need to factor a pit strategy into their racing. Lighting effects around the tracks mimic the race's 24-hour cycle from day to night to day. Precise road conditions and collision effects allow for realistic crashes, spinouts, and flips. The Le Mans mode allows players to compete in a 24-hour race, or compress it into 10-minute, 30-minute, one-hour, or six-hour modes. Up to four players can compete simultaneously via a split screen.
