Revealed barely months after the launch of the new E-Class sedan, the 2010 Mercedes Benz E63 AMG marks a departure from the usual AMG formula. A big horsepower, big block V-8 -- in this case the AMG-designed 6.2L M156 V-8, which punches out 518 hp and 465 lb-ft of torque -- remains the heart of the car. But Mercedes-AMG boss Volker Mornhinweg promises a radical improvement in handling as well. Canyon carving agility, rather than brute horsepower, is the new mantra at AMG (at least for its smaller sedans). The new E63 therefore boasts an entirely new front suspension, with a track that's been widened 2.2 in. over the standard E-Class.
Other changes include steel front springs (more sensitive than air springs, which are retained at the rear for ride height control, says AMG), a tubular stabilizer bar, new control arms, new wheel bearings, new bushing geometry and kinematics, and new wheel location for more negative camber. The rack-and-pinion steering features a 14:1 ratio, 22 percent quicker than the regular E-Class. The new E63 also gets the latest version of the Speedshift wet clutch seven-speed transmission that debuted last year in the SL63. The transmission has four modes -- "C" (for "controlled efficiency," says Benz, not comfort), "S" (sport), "S+" (sport plus) and "M" (manual). In full-commando manual mode, the transmission switches ratios in 100 milliseconds. And it offers launch control.
Mornhinweg claims the E63 will sprint from 0 to 60 mph in 4.4 sec. Top speed is limited to 155 mph, though if you order the optional AMG Performance Package, they'll re-flash the computer to allow you to reach 186 mph. The Performance Package (as if the regular E63 is soft-core) also buys you lightweight 19-in. forged alloy wheels (standard wheels are 18 in.), stiffer springs, and a trick locking rear diff. Oh, and a three spoke steering wheel. The E63 AMG makes its U.S. sales debut in November.
