Despite the minimal increase in power the car is said to quaff 12 percent less fuel resulting in an average consumption of 22.4mpg. One of the components credited for this is the Speedshift MCT 7-speed gearbox found in the SL63 AMG. It has four driving modes namely Controlled Efficiency, Sport, Sport Plus and Manual.
The standard car comes wearing 18-inch AMG alloys with size 255/40 front and 285/35 rear tyres. There is an optional 19-inch rim available. In terms of exterior cosmetics the big AMG gets LED daytime running lights, a more aggressive front spoiler, a rear diffuser and four tailpipes as per current AMG standard issue.It is expected that the new E63 AMG sedan will go on sale in the UK in September. It is also expected that the public will get first live glimpse at the 2009 New York International Auto Show next week.
[Editor's Note] Press release first mentions 6.3-liter V8 engine and then later states 6208 cc. To comply with German law, Mercedes-Benz is required to round up the displacement figure to 6.3 when used for marketing purposes.
