The new 2012 Mercedes-Benz E63 AMG has been unveiled at the New York Auto Show. The new E63 AMG is now even more powerful and efficient. As part of the AMG Performance 2015″ model strategy, the high-performance E-Class now features the new 5.5-litre V8 bi-turbo engine. Familiar from the 2012 CLS63 AMG this new engine can produce either 518 hp or 550 hp, together with an impressive reduction in fuel consumption – 22% less based on the European driving cycle. Also responsible for improved fuel economy is the newly developed electromechanical AMG speed-sensitive sports steering system which only draws power during steering wheel movements.


This V8 powerhouse, designated internally as the M157, boasts a combination of innovative high-tech components such as spray-guided direct gasoline injection with piezo injectors, a full aluminium crankcase, 4-valve technology with camshaft adjustment, air/water intercooling, generator management and an Eco Stop/Start system. With a displacement of 5,461 cc the eight-cylinder engine develops a peak output of 518 hp and torque of 516 lb-ft. In conjunction with the optional AMG Performance Package, these figures increase to 550 hp and 590 lb-ft. Both variants of the E63 AMG achieve exceptional performance: acceleration from zero to 60 mph takes 4.4 and 4.3 seconds respectively and the top speed is 155 mph or 186 mph with the AMG Performance Package (electronically limited).

The improvements in output and torque that come with the AMG Performance Package can be attributed primarily to an increase in the maximum boost pressure from 14.5 to 18.8 psi. The obvious differentiation of E63 AMG is provided by a carbon fibre engine cover, AMG Performance steering wheel with black Alcantara side grips, red-painted brake callipers and a carbon fibre trunk lid spoiler.
