Why it matters

The 300 SL had the world’s first four-stroke production engine with direct fuel injection. Its doors open upwards because the tubular space frame needed high sills – not as a styling gimmick. 29 coupés were built with aluminium bodies.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

The 300 SL Coupé was presented at the International Motor Sports Show in New York on 6 February 1954. Max Hoffman, Mercedes-Benz’s importer for the eastern United States and from late 1953 its general agent for the whole country, is credited by magazines with pushing for the car; Mercedes-Benz’s own text credits him with the 190 SL and the 1957 300 SL Roadster. The launch price in Germany was DM 29,000. After the coupé, 1,858 300 SL Roadsters were built.

How it differs from the standard 300 SL Coupé “Gullwing” (W 198)

Only 29 of the 1,400 Gullwings were built with an all-aluminium body, to customer order in Mercedes-Benz’s racing department at Untertürkheim – most of them in 1955.

The aluminium body saved roughly 80–107 kg depending on the source. Rudge centre-lock wheels were standard, and many cars had the NSL high-performance engine (240 instead of 215 PS). The aluminium body added $1,307 to the US base price.

Identifying a genuine Mercedes-Benz 300 SL “Alloy” Gullwing

RM Sotheby’s, citing factory records, gives 24 cars in 1955 and 5 in 1956; Sports Car Market (2008) gives 26 and 3. Both agree on 29 in total.
