The stage is set for the new Mercedes-Benz SL 63 AMG. Planned to follow the U.S. debut of the new-generation SL550 roadster later this year, the latest version of the high-performance SL model features more power, lighter weight and approximately 30 percent better gas mileage.
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. 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 new SL 63 AMG is yet another masterpiece from Mercedes-AMG. Be it driving dynamics, lightweight construction or efficiency – the SL 63 AMG represents a giant leap forward. Following on from the SLS AMG Roadster and the SLK 55 AMG, our unrivaled roadster family is practically complete."
The SL 63 AMG is available with two power levels for the first time. Normally, the AMG 5.5-liter twin-turbocharged "biturbo" V8 delivers 530 horsepower and 590 lb.-ft. of torque. The optional AMG Performance Package raises these figures to 557 hp and 664 lb-ft, respectively.
The result is an acceleration from 0 to 60 mph in 4.2 seconds, and the top speed is electronically limited to 186 mph with the AMG Performance package. 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 twin tailpipes produces a distinctive engine sound.
