Six-Decade SL Heritage: A Legacy of Innovation
For over six decades, the SL has held a prominent position in the Mercedes-Benz lineup. The original SL, the 1952 300SL, was a purebred race car, initially conceived without a road-going counterpart. With its groundbreaking tubular space frame, aerodynamic teardrop-shaped aluminum body featuring iconic gullwing doors, and direct-fuel-injection engine, the 300SL was remarkably advanced for its time. Its racing pedigree was quickly established with victories at the 24 Hours of Le Mans and the Carrera Panamericana in its debut season.
Responding to the urging of Max Hoffmann, the U.S. Mercedes-Benz importer, a road-going version of the 300SL was engineered and fittingly debuted in New York. The car became affectionately known as the “Gullwing” due to its distinctive doors, a design necessitated by the space-frame chassis. Alongside the 300SL, the 190SL, a smaller and more accessible convertible, was introduced in 1955, further expanding the SL lineage. The 2016 Mercedes-Benz SL continues this remarkable heritage, embodying the enduring spirit of innovation, performance, and luxury that has defined the SL for generations.
