instead of 300 SL's engine. Both 300 SL roadster and 190 SL have soft fabric folding top and optional removable hardtop. The production for 300 SL and 190 SL ended in 1963 with the introduction of W113 SL-Class. Model Range 300 SL (Gullwing): 1954–1957, 3.0 L I6 300 SL (Roadster): 1957–1963, 3.0 L I6 190 SL: 1955–1963, 1.9 L I4 W113 (1963—1971) Replacing both 300 SL and 190 SL, 230 SL was introduced in 1963 with distinctive concave roofline that earned the nickname "pagoda top". The W113 featured a low waistline, large curved greenhouse windows, detachtable hardtop, and a new 2.3-litre six-cylinder inline engine. For 1967, the engine was enlarged to 2.5 litres, and 230 SL was renamed as 250 SL. The changes were made to the interior with new dashboard padding, switches and knobs, steering wheel, and door pockets (US model only). The wheel covers fitted to 250 SL and 280 SL replaced the smaller hubcaps. A year later in 1968, the engine was enlarged again to 2.8 litres, and the 250 SL was changed to 280 SL. Model Range 230 SL: 1963–1967, 2.3 L I6 250 SL: 1966–1968, 2.5 L I6 280 SL: 1967–1971, 2.8 L I6 R107 (1971—1989) In 1971, R107 was introduced with new design language and safety features that spread to the subsequent Mercedes-Benz models. For the first time, the V8 engines were fitted to the SL-Class. With the production from 1971 to 1989, R107 was one of few longest-produced vehicles from Mercedes-Benz. R107 received a very minor update in 1972 with new rubber-edged wing mirrors from W116 and a major update in 1985 for 1986 model year. The engine options were updated in 1980 for the 1981 model year with new aluminium V8 engines from W126 S-Class introduced in 1979 while the 2.8-litre six-cylinder inline engine carried over. It was updated again in 1985 for the 1986 model year with new 3.0-litre six-cylinder inline engine from W124 and enlarged 4.2- and 5.5-litre V8 engines while the 5.0-litre V8 engine carried over. The SLC Coupe is much rarer, produced from 1971 - 1981, as 280, 350, 380 and 450 SLC. With the 450 SLC, 450 SLC 5.0 and 500 SLC models, Daimler-Benz took part in major rallies at the end of the 1970s such as the 30,000 km long Vuelta à la America del Sud (1977), the Safari Rally (1979) and the Bandama Rally.
