The Mercedes-Benz 220 SL Prototyp was a testbed for what would become the iconic Pagoda series. It used a 2.2-liter inline-six engine adapted from the 220 S sedan, producing approximately 100–110 hp. The prototype featured an early version of the independent suspension and experimental chassis refinements, blending touring comfort with sportier dynamics. Only a handful were built for evaluation and testing.

Design

Visually, the Mercedes-Benz 220 SL Prototyp featured elements that foreshadowed the W113 “Pagoda.” It had a lower-slung body, more squared lines than the 190 SL, and styling cues that looked toward the future. The interior was experimental, blending 300 SL minimalism with luxury sedan comfort. Exterior proportions were elegant, purposeful, and noticeably modern for the late 1950s.

Historical Significance

Though never mass-produced, the Mercedes-Benz 220 SL Prototyp was a critical stepping stone between the 190 SL and the 230 SL. It helped Mercedes engineers refine the mix of comfort, safety, and performance that would define the next generation. Its influence was fully realized in 1963 with the launch of the 230 SL “Pagode.”

Quirks and Pop Culture

Only a few photos and internal documents exist of the Mercedes-Benz 220 SL Prototyp, making it a bit of a unicorn in Mercedes history. It’s occasionally featured in museum exhibitions but never saw road use or pop culture fame. Among collectors and historians, it’s a “what might have been” legend.

Display and preservation

The vehicle was exhibited at the Oldtimer-Meeting Baden-Baden in 2022. Set in the elegant spa gardens of Baden-Baden, this open-air event is one of Germany’s most atmospheric classic car gatherings. The 2022 edition marked the 46th year of the meeting and featured over 350 carefully selected vintage vehicles from across Europe. With its picturesque backdrop and festive ambiance, the event draws thousands of visitors who stroll among historic automobiles, enjoy live music, and take in themed displays. In 2022, American classics and convertibles were especially well represented, reflecting the event’s continued celebration of both international and domestic automotive heritage.

Conclusion

The 1957 Mercedes-Benz 220 SL Prototyp is one of those rare pieces of automotive history that shaped the future without ever going on sale. It represents the quiet genius of Mercedes-Benz’s development path toward the beloved SL lineage.
