AMG Power
Powerful hand-built AMG engines power the two AMG versions of the SL. The SL63 gets a twin-turbocharged 5.5-liter AMG V8 that produces 577 horsepower and 664 lb-ft of torque at 2250 rpm, combined with the AMG SPEEDSHIFT MCT 7-speed sports transmission to handle the power transfer to the rear wheels. Engine and transmission software have been revised to deliver faster shifts than the previous model, especially in Sport Plus mode and manual shifting. A twin-turbocharged 6.0-liter AMG V12 powers the SL65, producing 621 horsepower and 738 lb-ft of torque, combined with the AMG SPEEDSHIFT PLUS 7G-TRONIC designed to handle the massive torque. Mercedes-Benz figures indicate the SL63 will accelerate from zero to 60 mph in 4.0 seconds, with the SL65 slightly quicker at 3.9 seconds. Both cars are electronically limited to a top track speed of 186 mph.
