The new E-Class has already been revealed in spy photos, but now it is confirmed that when the E63 AMG debuts, it will do so with its own version of Mercedes’ 4Matic AWD.
The Mercedes 4Matic setup couldn’t simply be transferred into the AMG model as is, so it was tweaked to save weight, and to make sure the torque split was more sports-car oriented.
The standard split is 45/55 front/rear, but in adverse conditions, that can be changed to 30/70, or to 70/30, depending on the situation the car is in. In the AMG model, torque split can be adjusted only as far as 33/67, keeping the rear-wheel bias and the performance DNA of the car going. AMG says that with this AWD setup, the E63 will only gain around 44 lbs.
In the current E63, a 518 hp 5.5-liter twin-turbo V8 produces 516 lb-ft of torque, though you can opt for a performance package which makes 550 hp and 590 lb-ft of torque.
In the new E63 there will only be one option, a twin-turbocharged 5.5-liter V8 that produces 575 hp and an estimated 590 lb-ft of torque, which will be more usable now that the AWD system is in place. The previous E63 made the jump from 0-60 in about 3.8 seconds, but now with power going to all the wheels, .4 seconds has been shaved off for a total 3.4 seconds 0-60 sprint, according to AMG.
