The facelifted Mercedes S63 AMG loses AMG’s 5.4L M113 in favor of the newer M156 6.2L V8 used in the S63 AMG, CLK63 AMG and C63 AMG. It produces 525 PS at 6800 rpm and 630Nm of torque at 5200 rpm. It can accelerate from rest to 100 km/h (62mph) in 4.6 second going up to a limited top speed of 250km/h (155mph). Also the Mercedes S63 AMG has the new AMG developed 7-speed MCT Multi Clutch Technology semi-automatic transmission. The new MCT transmission is essentially the 7G-Tronic transmission without a torque converter. Instead of a torque converter, it uses a compact wet startup clutch to start the car off, and also supports computer-controlled double declutching. The MCT (Multi-Clutch Technology) acronym refers to a planetary (automatic) transmission’s multiple clutches and bands for each gear. The MCT is fitted with four drive modes:“C (Comfort), S (Sport), S+ (Sport plus) and M (Manual) and boasts 100 millisecond shifts in M mode. the new car features the new AMG DRIVE UNIT with innovative Race Start function. The AMG DRIVE UNIT is the central control unit for the AMG SPEEDSHIFT MCT 7-speed sports transmission and all driving dynamics functions. The driver can change gears either using the new AMG selector lever with its leather/ carbon-fibre finish, or by nudging the AMG steering-wheel shift paddles. The new Race start Function is basically a launch control system which enables the Mercedes S63 AMG driver to call on maximum acceleration, while ensuring optimum traction of the driven wheels. A modified version of the Mercedes S63 AMG is the safety car for the 2008 Formula One season.
