Mercedes-Benz E63 AMG Estate
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).
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 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.
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 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 three suspension modes of "Comfort", "Sport" and "Sport plus" at the touch of a button.
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.
A striking feature of the high-quality, exquisitely crafted 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.
With immediate effect, over a dozen driver assistance systems in the E 63 AMG help to avoid traffic accidents or mitigate the severity of an accident. Among the new systems are Active Blind Spot Assist and Active Lane Keeping Assist. Active Blind Spot Assist warns the driver if the short-range radar sensors detect that there is a risk of collision should the vehicle change lanes. If the driver ignores these warnings and comes dangerously close to the vehicle in the next lane, Active Blind Spot Assist will intervene. By applying braking force to the wheels on the opposite side of the vehicle, controlled through the 3-stage ESP® system, a yaw movement is created which counteracts the collision course.
Active Lane Keeping Assist is also linked to the 3-stage ESP®. This system kicks into action if the driver inadvertently drifts over a solid line to the right or left of a lane. In this case, Active Lane Keeping Assist brakes the opposite wheels and thereby prevents the vehicle from crossing the line. A display on the instrument cluster warns the driver at the same time. If broken lane markings are crossed, the system controls an electric pulse generator in the steering wheel which generates vibrations for a short time – a discreet but highly effective cue to countersteer immediately. Before the braking system intervenes, the steering wheel always vibrates to provide a warning.
