Thanks to its aluminum bodyshell (similar to the SLS AMG super sports car),
the weight of the new SL63 AMG has been reduced by 275 pounds. With a curb
weight of 4,059 pounds (estimated) and 530 horsepower, the new model boasts
unparalleled performance and an extraordinary driving experience.
Performance is also enhanced with a winning combination: AMG active suspension
(based on ABC Active Body Control), new AMG speed-sensitive sports steering, the
AMG high-performance compound brake system and the AMG SPEEDSHIFT MCT 7-speed
sports transmission. Topping off this impressive package is an enticing mix of
stylish design, extensive standard equipment and a high safety level.
Ola Källenius, CEO at Mercedes-AMG GmbH: "The 2013 SL63 AMG is yet another
masterpiece from Mercedes-AMG. Be it driving dynamics, lightweight construction
or efficiency - the SL63 AMG represents a giant leap forward. Following on from
the SLS AMG Roadster and the SLK 55 AMG, it now makes our unrivalled roadster
family practically complete."
For the first time, the SL63 AMG is available with a choice of two power
levels. Normally, the AMG 5.5-liter twin-turbocharged "biturbo" V8 delivers 530
horsepower and 590 lb-ft of torque. With the optional AMG Performance Package,
these figures rise to 557 hp and 664 lb-ft respectively.
The result is acceleration from 0 to 60 mph in 4.2 seconds and top speed is
electronically limited to 186 mph with the AMG Performance package, and thanks
to its new direct-injection V8 engine, gas mileage is a full 30 percent
(estimated) better than the outgoing model.
The new V8 powerplant in the SL63 AMG (identified internally as the M157)
features a combination of innovative high-tech components for high power output
and low fuel consumption. In addition to spray-guided direct injection, the
engine boasts an all-aluminum block, twin turbochargers, four valves per
cylinder with variable valve timing, air/water intercooling, alternator
management and an ECO stop/start system. The weight-optimized AMG sports exhaust
system with a pair of twin tailpipes produces a distinctive engine sound.
