The SL-Class has been a convertible icon for decades. Three twin-turbo engines are on the menu: a 429 hp 4.6 litre V8, a 530 hp 5.5 litre V8 (SL63 AMG – 557 hp with the “Performance Pack”) and the 621 hp 6.0 litre V12 (SL65 AMG). The retractable rigid roof can be equipped with the “Magic Sky Control” glass, with driver-controlled opacity. No all-wheeldrive versions for the SL-Class, but many electronic driver aids are offered depending on trim.
