Mercedes-Benz 300 SL 0–60 Times

Across 4 verified tests spanning 1955 to 1992, the Mercedes-Benz 300 SL traces a clear performance arc from mid-century sports coupe to later grand-touring roadster. The earliest results come from the W198 era, where the M198 naturally aspirated gasoline six produced 215 hp and set the model's benchmark pace. The 1955 Gullwing Coupe remains the quickest 300 SL tested, reaching 60 mph in 7.4 seconds and covering the quarter-mile in 15.2 seconds at 94 mph. Other W198 tests keep that early series clustered around the same level, giving the generation a 7.87-second average to 60 mph.

After the W198 ended in 1963, the 300 SL name returned in the R129 period as a different kind of performance car. In tested form, the 1992 Roadster used the naturally aspirated M104 gasoline engine with 228 hp and recorded 8.8 seconds to 60 mph, making it slower than the earlier Gullwing-based cars but representative of the later model's roadster configuration and broader touring brief. That leaves the 300 SL's verified record defined by two gasoline-powered eras: the W198 as the faster and more competition-oriented phase, and the R129 as the final production chapter covered by the available tests.
