Taking cues from the Gullwing, Wilfert and Häcker designed the body of the 190 SL to look sporty, yet elegant, without compromising on performance. An innovative spirit shaped the car from the outside in, introducing new tools in the Mercedes-Benz arsenal. These included a monocoque sports car chassis, a low-pivot rear suspension, an overhead camshaft-driven engine, winding windows, an all-synchromesh four-speed manual transmission and independent heating controls for driver and passenger.
