The Mercedes-Benz SL is a roadster manufactured by Mercedes since 1954. The designation SL derives from the German Sport Leicht, or Sport Light � and was first applied to the 300SL 'Gullwing' named also after its "gullwing" or upward-opening doors. The term SL-Class refers to the marketing iterations of the vehicle, including the numerous engine configurations spanning five design generations.

The 300SL roadster succeeded the Gullwing in 1957. The 4-cylinder 190SL was more widely produced with 25,881 units, starting in 1955. Cars of the open SL-Class were available as a coupe with a removable hardtop or as a roadster with convertible soft top or with both tops. Production for the 190SL and 300SL ended in 1963. Next came the SL-Class 230SL, a new design with a low waistline and big curved greenhouse windows, and a Coupe Roadster whose distinctive roofline earned the nickname "pagoda top." Around 1968 the engine received a displacement increase and the model became known as the 250SL. The last two years of production as the 280SL saw minor changes to switch knobs, and wheel trim rings became full hubcaps.
