Mercedes-Benz E63 AMG
The E 63 AMG is now even more powerful and efficient. As part of the "AMG Performance 2015" model strategy, the high-performance vehicle now benefits from the new 5.5-litre V8 biturbo engine. This unit, already familiar from the CLS 63 AMG, delivers an output of 386 kW (525 hp) to 410 kW (557 hp), together with an impressive reduction in fuel consumption: the E 63 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. An important contribution is also made here by the newly developed electromechanical AMG speed-sensitive sports steering system, which only draws power when the vehicle is actually being steered. Additional assistance systems now raise occupant safety to a whole new level.
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. With a displacement of 5461 cc, the eight-cylinder engine develops a peak output of 386 kW (525 hp) and torque of 700 Nm. In conjunction with the optional AMG Performance package, these figures increase to 410 kW (557 hp) and 800 Nm. Both variants of the E 63 AMG achieve exceptional performance: acceleration from zero to 100 km/h takes 4.3 and 4.2 seconds respectively (Estate: 4.4 and 4.3 seconds), and the top speed is 250 km/h (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 charge pressure from 1.0 to 1.3 bar. Visible differentiation is provided by the exceptionally high-quality engine cover in genuine carbon fibre. The AMG Performance package also includes the AMG Performance steering wheel with black Alcantara in the grip area, red-painted brake callipers and, in the case of the Saloon, the genuine carbon fibre AMG spoiler lip on the boot lid and the electric rear window blind.
A major contribution to the car's exemplary consumption figures is also made by the AMG SPEEDSHIFT MCT 7-speed sports transmission. In place of a conventional torque converter, this uses a compact wet start-up clutch. The E 63 AMG also features a stop/start function as standard: this is active in the Controlled Efficiency ("C") transmission mode and switches the eight-cylinder engine off when the vehicle comes to a standstill. The stop/start function can be activated or deactivated using the ECO button on the centre console. When in transmission mode "C", the vehicle will always start up in second gear. The system will also change gears noticeably early and avoid high engine speeds. Demand-driven delivery of fuel and a generator management system with braking energy recuperation during deceleration add further to the economic use of fuel.
"S" (Sport), "S+" (Sport plus) and "M" (Manual) enhance the car's agility quite noticeably. Shorter response times, higher engine speeds and more spontaneous gear changes demonstrate the full potential of the new AMG V8 biturbo engine. In all three transmission modes, not only is the stop/start system deactivated but, at full load, the engine management system partially suppresses the cylinders. This carefully managed interruption to ignition and injection results in faster gear changes and an emotive acoustic effect. The automatic double-declutching function in reverse gear provides the perfect complement.
Externally, the E 63 AMG with the new M157 engine is identifiable by its new light-alloy wheels and by the "V8 BITURBO" lettering on its distinctive, wider front wings. Further characteristic features to aid recognition include AMG bodystyling with a specific design for the front and rear, along with AMG side sill panels and an AMG sports exhaust system with two chrome-plated twin tailpipes.
