All of that power is channeled through the E63 S wagon's 9-speed MCT (multi-clutch technology) automatic transmission to a 4MATIC+ all-wheel-drive system. The result is a wagon suitable for draggin' with a claimed 0-60 mph time of 3.4 seconds. This is an improvement of about 0.2 seconds over the last E63 wagon, and only a tenth behind the new E63 S sedan.
The E63 S wagon's all-wheel-drive system, like in the E63 S sedan, can also vary the amount of torque front and rear. It can even shift 100 percent of the torque to the rear, where an electronic limited slip differential also lurks. As is the current fashion, electronic trickery can give the wagon a "drift mode," just like in the sedan. The feature is activated when the car is in "RACE" drive mode, stability control switched off, and the 9-speed transmission set to manual shifting.
In addition to the E63 S wagon's tire-slaying equipment, there is an adjustable air suspension that can vary stiffness based on driving conditions and driver preference, plus ventilated and drilled 15.4-inch front disc brakes matched to 14.2-inch rotors in the back. The front rotors are stopped by six-piston calipers while the rears make do with single-piston units. The rotors can also be upgraded to optional carbon ceramic versions.
The E63 S wagon will make its official debut at this year's Geneva auto show in March, just as the E400 wagon reaches US dealers. The standard wagon will be joined by the AMG model by this fall. Mercedes has not released pricing for either wagon.
