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 2015â€³ 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).
