The high-performance end of the range (supercharged SL55 AMG, V12 SL65 AMG, and tuner builds like Brabus T12 and Renntech) is treated as a different animal: brutally fast, traction-limited, and a relative bargain against an SL65's price. Owners of modified cars caution respect for the throttle, and note the SL600's torque can out-launch even the more powerful SL65 due to traction.
AMG and tuner variants: SL55, SL65, Brabus, Renntech
