Unveiled at the 1954 New York Auto Show, the 300 SL coupé arrived with doors that opened toward the sky — a solution born from a tubular spaceframe chassis that left no room for conventional hinges.
Beneath the gullwing bodywork sat a fuel-injected inline-six derived from Mercedes-Benz's racing program, propelling the 300 SL to speeds few production cars of the 1950s could approach.
In 1957 the gullwing gave way to an open roadster, built alongside it in far greater numbers. By the time production ended in 1963, Mercedes-Benz had built 3,258 examples of the 300 SL — a car that remains the benchmark for 1950s performance and design.
Every model.
4 distinct series across US model years 1955–1963 — from the alloy-bodied gullwing coupé to the roadster that replaced it, each identified by its chassis and engine numbers.
