The heart of a sports car

At the heart of the 300SL Roadster lies a formidable 3.0-liter inline-six engine, a direct descendant of the legendary powerplant that propelled its predecessor, the 300SL Gullwing, to victory on both road and track. This potent engine churns out an impressive 215 horsepower, delivering exhilarating acceleration and a top speed exceeding 140 mph. Mated to a responsive four-speed manual transmission, the Roadster offers a driving experience characterized by seamless power delivery and agile handling, ensuring thrills at every turn.

Bosch mechanical injection

One of the most significant technical innovations of the 300SL Roadster is its pioneering fuel injection system, a groundbreaking feature developed by Bosch. This system optimizes fuel delivery, enhancing both performance and fuel efficiency while simultaneously reducing emissions—a remarkable achievement for its time. Complementing this innovation is the Roadster’s advanced independent suspension setup, which provides exceptional ride comfort and stability, even when pushing the car to its limits.
