The new version of the Mercedes-Benz E63 AMG packing upgraded features and a completely new engine, with added performance. 6.2-liter V8 engine that has powered the E63 AMG since 2009, now comes the same twin-turbocharged, 5.5-liter V8 mill found in the CLS63, the S63 and the CL63 AMG. The blown unit kicks out 518 hp, or the same as the old engine, although peak power is now developed earlier in the range, at 5,250 rpm. Torque grows to 516 lb-ft at just 1,700 rpm, or 3,500 rpm earlier than before.
