“Out goes the familiar, naturally aspirated 6.2-liter V8 engine that has powered the E63 AMG since 2009. In comes the same twin-turbocharged, 5.5-liter V8 mill found in the CLS63, the S63 and the CL63 AMG.”
“The E63 was already among the fastest production sedans on sale in the U.S. market. With the switch to AMG’s latest engine, it not only gains a solid dose of added torque, but a further dimension in performance, with improved off-the-line acceleration, greater in-gear shove, more refined cruising traits and–as far as turbocharged powerplants go–a terrific baritone blare at full tilt.”
“With all of that torque concentrated so low in the range, you’re pretty much on top of it the moment you step away from the line. From there on, the performance builds in one linear surge all the way to redline. There’s no apparent turbo lag, and at pretty much any revs, in any gear, there is vast thrust. Speed builds quickly and, owing to the smoothness of the delivery, rather deceptively. “
“Those in the market for a rapid sedan will no doubt be tempted by the reworked E63. The changes AMG brought to its latest model make it a better everyday proposition while extending its haughty performance potential and providing it with impressive fuel economy when driven at posted limits.”
