The enlightenment of lightness.
Nearly 140 kg lighter than its previous generation, the sophisticated body structure of the 2018 SL is crafted almost entirely from diecast, chilled-cast, hydroformed and extruded aluminum. With 20% greater rigidity, it tips the scales in favor of greater safety, comfort, and most of all, athletic performance.
Four tires on a mission: Corner-carving confidence
With rigid yet lightweight components, the 4-wheel multilink suspension teams with semi-active damping for crisp handling with silky smoothness. Industry-advancing Active Body Control (ABC) adds innovative curve-tilting on the SL 550 or as an SL 450 option. The AMG Sport Suspension, also based on ABC, is honed to even sharper, track-tuned edge.

 Even the most advanced safety systems may not be sufficient to avoid an accident. It is the driver’s responsibility at all times to be attentive to traffic and road conditions, and to provide the steering, braking and other driving inputs necessary to retain control of the vehicle. Drivers are cautioned not to wait for system alerts before braking or taking evasive action, as that may not afford sufficient time and distance. See Operator’s Manual for system’s operating speeds and additional information and warnings.
