Sportlich. Leicht. Perfected.

Beneath the styling sat engineering theatre: an automatic roll bar that deployed in 0.3 seconds when sensors detected an imminent overturn, electrically adjustable seats with integrated belts, and adaptive damping on the flagship models.
Over thirteen years Mercedes-Benz built 213,089 examples, spanning everything from the six-cylinder 300 SL to the 7.3-liter V12 SL 73 AMG — the largest engine fitted to a production Mercedes-Benz of its era.

23 distinct series across 1990–2002 — from the six-cylinder 300 SL to the 7.3-liter SL 73 AMG, each identified by its chassis, engine and transmission numbers.
