Mercedes will be unveiling the high-performance AMG version of its E-Class sedan, the 2010 E63 AMG, at the New York Auto Show next week. They claim its performance, handling, and technology will closely mirror the SL63 AMG Roadster when it goes on sale this November at U.S. dealerships.
In addition to the expected collection of uber-luxury appointments and options - and some unexpected ones, like the newly standard ATTENTION ASSIST drowsiness detection system - the 2010 E63 AMG has significant mechanical changes that differentiate it from the previous model.
For one, fuel economy is up nearly twelve percent. By fitting the AMG SPEEDSHIFT MCT 7-speed sports transmission used in the SL63 AMG, they've eliminated the inefficiencies of a torque converter while simultaneously ensuring more sporting performance. On-demand delivery of fuel to the cylinders plus an aggressive alternator that takes advantage of engine power on overrun adds more efficiency to the 2010 E63 AMG.
But the E63 isn't about efficiency. It's a sharp-handling, tarmac-eating receptacle for the mighty 6.3-liter (well, actually, 6.2-liter) V-8 that whomps out 518 hp and 465 lb-ft torque in this application. Mercedes says that the 0-60 mph sprint occurs in a scant 4.4 seconds. The aforementioned Speedshift MCT transmission boasts rev-matched downshifts and a race start function that provides consistent stoplight sprints. Powertrain electronics stop the fun at 155 mph.
To manage all that power better than before, they've beefed up the suspension both front and rear. The front axle is shared with the C63 AMG and now features steel springs. It's 2.2 inches wider and features newly designed bushing geometry as well as more negative camber for greater grip at speed. The rack and pinion steering setup has been retuned with a quicker ratio and better feel. The rear axle retains Mercedes' air springs for maximum comfort and level control. The entire setup is graced with AMG Ride Control that allows the driver to adjust the ride/handling balance from the cockpit.
If all this isn't fast enough for you, check the option for the AMG Performance Package and enjoy the following additions to the 2010 E63 AMG:
• Lightweight, forged 19-inch AMG light-alloy wheels with 255/35 R19s
up front and 285/30 R19s in the rear
• Performance suspension with stiffer spring rates
• Rear axle locking differential with 40 percent locking action
• Performance steering wheel in a three-spoke design
• Top speed raised to 186 mph
