2012 model year Mercedes-Benz E63 AMG is now even more powerful and efficient. The high-performance vehicle now benefits from the new 5.5-litre V8 biturbo engine. This unit also found in the new CLS 63 AMG, delivers 525 hp to 557 hp with theoptional AMG Performance package.

The E63 AMG consumes 9.8 litres per 100 kilometres (Estate 10.0 litres) according to NEDC combined, in other words 22 percent less than its predecessor with the AMG 6.3-litre V8 naturally aspirated engine.

This eight-cylinder powerhouse, designated internally as the M 157, boasts a combination of innovative high-tech components: in addition to spray-guided direct petrol injection with piezo injectors, these include a full aluminium crankcase, four-valve technology with camshaft adjustment, air/water intercooling, generator management and a stop/start system.

Acceleration from zero to 100 km/h takes 4.3 and 4.2 seconds with the optional AMG performance package (Estate: 4.4 and 4.3 seconds), and the top speed is electronically limited to 250 km/h.

Despite its increased output, higher torque and improved performance, the new E 63 AMG shows an improvement of 2.8 litres in fuel efficiency compared with the previous model with V8 naturally aspirated engine.
