The Le Mans Classic is a biennial vintage sports car event held on the grounds of the 24 Hours of Le Mans. The event consists of a series of races for cars which have competed at the 24 Hours of Le Mans or for similar cars of the same model. The traditional classes feature cars from prior to 1981 (originally 1979, but 1981 was the last year of the formula), with all cars being broken into six different eras.
