The horsepower war between the major German automakers is over, they say. The reveal of an updated Mercedes E63 model for 2014, setting a new benchmark of 577 hp, suggests old rivalries are still strong.
Updated with a bold new look, this mid-cycle refresh for the AMG-tuned E-Class brings with it more changes than that, including the addition of all-wheel drive.
Powering both the sedan and wagon E63 models continues to be the brand's twin-turbo 5.5-liter V8 engine, with an output increase of 32 hp and 15 lb-ft of torque for a new total of 550 hp and 531 lb-ft. Those who want more (more than the BMW M5 or Audi RS6) can opt for the S-Model package, with the full 577 hp and a massive 590 lb-ft of torque. That car can hit 60 mph in just 3.5 seconds, while the standard version will do it in 3.6.
Helping put all that power to the ground is a 4MATIC all-wheel drive system, a first for an AMG car, with a rear-biased 33/67 power distribution. The AWD does, however, add an extra 154 lbs to the car's weight.
Being an AMG, the E63 boasts an AMG adaptive suspension, some big 19-inch wheels and upgraded brakes plus a faux-LSD torque vectoring braking system, while S-Models also gain a true limited slip differential in the rear.
And of course, it's hard to miss the new look for 2014 with larger front intakes and the new dual-headlights design, while the interior is the usual oasis of Nappa leather and Alcantara throughout.
