The Mercedes-Benz SL is a grand tourer manufactured by Mercedes since 1954. The designation SL derives from the German Sport Leicht, or Sport Lightweight, 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 variations 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 2.3L mechanically fuel injected six cylinder engine. It featured a low waistline and big curved greenhouse windows, and a Coupe Roadster with detachable hardtop, whose distinctive roof line earned the nickname "pagoda top." The design was by Paul Bracq. Around 1967, the engine received a displacement increase and the model became known as the 250SL. Within a year the engine displacement was increased for the final time and the model designation became 280SL. Beginning with later versions of the 250SL changes were made to dashboard padding, switches and knobs, door pockets and steering wheel. In addition, the on the 280SL formerly separate center hub caps and wheel trim rings became full wheel-covers.

The SL received a face lift in 2008 featuring a new front end that evokes the classic 300SL with a large grille featuring a prominent 3-pointed star and twin "power domes" on the hood, the car also features new headlights with an optional "Intelligent Light System" and a new speed sensitive steering system.

In December 2011 Mercedes-Benz announced the all new SL-Class and was formally launched at the North American International Auto Show in January 2012. The new SL has been produced for the first time almost entirely from aluminum. The new aluminum body shell weighs around 110 kilograms less than it would using the steel technology from the predecessor. Although the Mercedes-Benz SL-Class has more assistance systems on-board than its predecessor and therefore does actually sacrifice some of the weight saved through the aluminum body-shell, the scales show some better figures: the SL 500weighs around 125 kilograms less and the SL 350 is 140 kilograms lighter than its predecessor.

New features include the unique Front-Bass system and adaptive windscreen wipe/wash system MAGIC VISION CONTROL, which supplies water from the wiper blade as required and depending on the direction of wipe. The R231 is also available with two different suspension systems, semi-active adjustable damping as standard. The optional active suspension system ABC is available as an alternative.
