2012 Mercedes-Benz E 63 AMG

2012 Mercedes-Benz E 63 AMG

The Mercedes-Benz E 63 AMG is now even more powerful and efficient. As part of the "AMG Performance 2015" model strategy, the high-performance car now benefits from the new AMG 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. As a result the E 63 AMG, which is available in Saloon and Estate variants, is the most efficient vehicle in its class. An important contribution to this is also made by the AMG SPEEDSHIFT MCT 7-speed sports transmission, and the newly developed electromechanical AMG speed-sensitive sports steering system. Additional assistance systems now also 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 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).

A quick glance at the technical data reveals the tremendous accelerating power of the eight-cylinder biturbo engine: no less than 700 Nm of torque can be called upon across a broad engine speed range from 1750 to 5000 rpm. When combined with the AMG Performance package, the driving experience becomes even more impressive: now precisely 800 Nm of torque is available between 2000 and 4500 rpm. The result is effortlessly superior power delivery, which can be enjoyed in manual "M" transmission mode in particular.

Fuel consumption reduced by 2.8 litres per 100 km

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. Fuel consumption, at 9.8 litres per 100 kilometres according to NEDC combined, corresponds to CO2 emissions of 230 grams per kilometre (Estate: 10.0 l/100 km; 234 g/km). Both variants achieve the same consumption and CO2 figures either with or without the AMG Performance package. As a result, the E 63 AMG takes the lead in a competitive comparison.

The improvement in output and torque that comes with the AMG Performance package is due primarily to an increase in the maximum charge pressure from 1.0 to 1.3 bar. Visible differentiation is provided by the 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.

AMG SPEEDSHIFT MCT 7-speed sports transmission helps save fuel

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.

Driving dynamics certainly don't suffer as a result: the transmission modes "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 function 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.

AMG RIDE CONTROL sports suspension and new steering system

The E 63 AMG features the AMG RIDE CONTROL sports suspension with a specially designed front axle: the track has been widened by 56 millimetres compared with the E 500, and includes independent wheel carriers, for increased negative camber at the front, giving clear benefits in terms of grip when driving fast through bends. Further features include steel suspension struts on the front axle and air suspension struts on the rear axle, with an automatic level control system. Also standard here is an electronically controlled damping system, which automatically adjusts the damping characteristics depending on the driving situation and reduces the roll angle of the body. The result: lightning-fast adjustment between optimum driving comfort and the best possible agility. The driver can switch between the suspension modes of "Comfort", "Sport" and "Sport plus" at the touch of a button.

The steering system on the E 63 AMG is also new: the electromechanical AMG speed-sensitive sports steering features a more direct ratio of 14:1 and variable power assistance that adapts according to the suspension mode. The result: extremely agile handling through bends. The steering also helps to reduce fuel consumption, since the power assistance system only draws power when the vehicle is actually being steered.

As well as the 3-stage ESP® system with SPORT handling mode, the standard equipment package includes an AMG high-performance braking system, with composite technology on the front axle. An even more powerful AMG ceramic high-performance composite braking system, 40 percent lighter in weight, is available as an option. Optimum grip comes courtesy of the new 18-inch AMG light-alloy wheels in a 10-spoke design, fitted with 255/R 40 R 18 tyres on the front and 285/35 R 18 on the rear. The "flowforming" production process already used with the SLS AMG and the CLS 63 AMG optimises the durability of the light-alloy wheels, while also reducing weight by up to 0.8 kilograms per wheel. The reduced unsprung masses help to improve both driving dynamics and ride comfort.

Significantly upgraded interior

A striking feature of the interior is the new AMG Performance steering wheel in a three-spoke design. The rim of this wheel, which is already used in the CLS 63 AMG, is flattened at both top and bottom to facilitate even better control of the vehicle. Further identifying features of the new steering wheel: aluminium shift paddles, the perforated leather in the grip areas and the three-dimensional design of the airbag cover with its "Silver Shadow" metallic trim element. This is complemented by the new E-SELECT shift lever with embossed AMG badge on the centre console.

Similarly adopted from the CLS 63 AMG is the three-dimensional full-colour TFT display in the centre of the speedometer. The driver is welcomed by a striking AMG logo that shows here as soon as the door is opened.
