Every earthly wish granted: three biturbo engines
The perfect complement to the lighter, tighter body of the SL are the new-generation V-8s in the SL550 and SL63 AMG, and the superlative SL65 AMG V-12. Twin turbos and an abundance of advanced technology deliver 429 hp, 32% more torque and 0-60 in just 4.5 seconds(†) from the SL550 V-8. The SL63 AMG's handcrafted biturbo V-8 raises the ante to 530 hp and 4.2 seconds, all with earth-friendlier efficiency and emissions. The SL65 AMG quickly goes all in, with a hand-built 621-hp biturbo V-12 that rushes you to 60 in just 3.9 seconds.
