The Mercedes-Benz 190SL was a two door grand touring convertible with a removable hardtop. It was produced by Mercedes-Benz from May, 1955 to February, 1963. A prototype was first shown at the New York Auto Show of 1954.
The 190SL was sold alongside the faster, more expensive Mercedes-Benz 300SL, which it closely resembled both in its styling and in its fully independent suspension, with both cars having double wishbone suspensions at the front and swing axles at the rear. However, the 190SL did not use the 300SL's purpose-built tubular spaceframe W198 platform, but was instead built on the shortened monocoque R121 platform, which was modified from the W121 small saloon platform.[2]
The 190SL was powered by a completely new, slightly oversquare 1.9L straight-four SOHC engine (Type M121 BII), that developed 105 PS (104 hp/77 kW) (or 120 gross hp) that earned itself a reputation for not running that smoothly[3] mostly due to the difficulty in propperly synchronising the twin-choke dual Solex carburetors, and that, in detuned form, was later also used in the W120 180 and W121 190 models. The car was available either as a soft-top convertible (initially priced at DM 16,500/$ 3,998[4]) or with removable hardtop (DM 17,650/$ 4,295). A nice option to be had, was the third-passenger transversal seat that could even fit an adult. In its early life, the 190SL could also be had as a sports-racing model with small perspex windscreen and aluminum doors. In 1959, the hardtop's rear window was enlarged.
The 190SL was also referred to as the Nitribitt-Mercedes after the scandal surrounding the murder of the call girl Rosemarie Nitribitt, who owned a 190SL.
Both the 190SL and the 300SL were replaced by the Mercedes-Benz 230SL in 1963.
