SLS AMG Gullwing

The Mercedes-Benz SLS AMG was unveiled at the 2009 Frankfurt Motor Show as AMG's first independently developed car, rather than a modified version of a standard Mercedes model. The project, internally designated C197, was a deliberate homage to the 1954 Mercedes-Benz 300 SL, featuring the same dramatic gullwing doors and a long-hood, short-deck proportion. Unlike the 300 SL, which used gullwing doors out of structural necessity (the tubular spaceframe prevented conventional doors), the SLS adopted them as a design statement, with the aluminum spaceframe specifically engineered to accommodate them.

The M159 6.2-liter naturally aspirated V8 was derived from AMG's M156 engine but extensively revised. Hand-built at Affalterbach, it produced 571 hp at 6,800 rpm and 650 Nm of torque at 4,750 rpm, with a dry-sump lubrication system that allowed a lower engine mounting position. The engine was positioned behind the front axle in a front-mid configuration for optimal weight distribution (47/53 front/rear). A seven-speed dual-clutch transmission was mounted at the rear in a transaxle layout, further aiding balance. The chassis was an aluminum spaceframe weighing just 241 kg, with double-wishbone suspension at all four corners.

The SLS AMG was available in multiple variants: the standard Gullwing coupe, the Roadster (with conventional side-opening doors), the GT (with revised suspension and more power), the Black Series (with 631 hp and aggressive aero), and the SLS AMG Electric Drive, which at its launch was the most powerful electric car in production. The car competed successfully in GT3 racing and spawned a customer motorsport program that demonstrated its genuine competition potential.

The SLS AMG cemented AMG's reputation as a manufacturer of genuine supercars rather than merely a tuning division. Its naturally aspirated V8, gullwing doors, and hand-built character give it a personality that turbocharged successors struggle to replicate. Values have remained strong, with the Black Series commanding significant premiums. The car represents a unique moment when AMG had the freedom to create their vision of the ultimate sports car without compromise.
