The Mercedes-Benz SL is a luxury roadster classified in the G/H segment. The first generation debuted in 1989, shortly after its unveiling at the Geneva Motor Show. This model introduced several innovative features, including an electro-hydraulically operated soft top and a wind deflector system designed to enhance passenger comfort in convertible mode. It was also among the first SL models to come standard with ABS brakes.
Initially, the SL was offered in several variants: the 300 SL (powered by the M103 engine with a displacement of 2960 cm³ and 190 hp), the 300 SL-24 (featuring the M104 engine with 2960 cm³ and 231 hp), and the 500 SL (equipped with the M119 engine delivering 4973 cm³ and 326 hp). In October 1992, the range expanded with the introduction of the 600 SL, powered by the M120 V12 engine producing 5987 cm³ and 408 hp.
Following a nomenclature update in 1993 and the discontinuation of the M103 engine, the 300 SL and 300 SL-24 were renamed SL 280 and SL 320, respectively. Later that year, Mercedes-Benz launched the SL 60 AMG—the first AMG-modified version of the SL to be offered as a series production model.
In September 1995, a refreshed version of the SL-Class was unveiled at the Frankfurt Motor Show. This update featured redesigned front and rear bumpers, new side skirts, a six-slat grille, and an optional transparent panoramic roof. A further facelift in April 1998 introduced oval side mirrors, upgraded interior materials, redesigned gauges and steering wheel, and body-colored door handles. That same year, the SL 60 AMG was discontinued and replaced by two new AMG variants: the SL 55 AMG (with the M113 engine, 5439 cm³, 354 hp) and the SL 73 AMG (featuring the M120 engine, 7291 cm³, 525 hp).
The original tyre sizes for the Mercedes-Benz SL include: 225/55 R16, 245/40 R18, 255/40 R18, 255/35 R19, 255/45 R17, 285/35 R18, 285/30 R19, and 295/35 R18.
Optional tyre sizes that can be fitted are: 235/45 R17, 245/45 R17, 255/40 R17, and 275/35 R18.
