E63 Wagon - After 2 years, it's back!

A forum member over at BenzBoost.com claims to have obtained a leaked copy of the model year 2012 Mercedes-Benz E-Class dealer ordering guide, revealing a few surprises.

Not only does the guide confirm the updated E350 and E550 engines we reported on last week, but it appears that after a two-year absence from the States, the E63 AMG wagon will join the already confirmed E63 sedan for the 2012 model year. The wagon will also receive AMG’s new 5.5-liter turbocharged V8 rated at 518 horsepower and 516 pound-feet of torque. The addition of the AMG Performance Package boosts the numbers to a CTS-V rivaling 550 hp/590 lb-ft.
And not only will the new AMG wagon haul more cargo than the sedan, but it should haul it faster; our past 0-60 mph tests of previous-generation AMG E-classes reveal that the wagon is usually 0.1 to 0.2 seconds faster than the sedan. How? Because the wagon has just enough additional weight in the rear to help the tires grip better and transfer all that power to the ground. The ordering guide estimates a 4.1 second 0-60 time for the sedan and 4.3 for the wagon, but OEM test results tend to be on the conservative side.
The ordering guide also states that the E550 will only be available in a 4Matic (four-wheel drive) variant for both the sedan and wagon. We’re not sure why, but we expect to get an explanation closer to its launch this coming fall 2011 (same goes for the E63 wagon).
