Affalterbach – Exciting design, ultimate performance and groundbreaking efficiency: this is what the new Mercedes-Benz CLS 63 AMG is all about. The top-of-the-range version of the four-door coupé is equipped with the newly developed AMG V8 biturbo engine, featuring a peak output of up to 410 kW (557 hp) and 800 Nm of torque, as well as the AMG SPEEDSHIFT MCT 7-speed sports transmission. On top of this, the vehicle's fuel consumption of 9.9 litres per 100 km (NEDC) represents an improvement of 32 percent compared with the previous model (all figures provisional).
The combination of an AMG RIDE CONTROL sports suspension with electronically controlled damping system and new front axle, newly developed electromechanical AMG sports parameter steering, and also optional AMG ceramic high-performance composite braking system, is synonymous with maximum driving dynamics. Visually, the CLS 63 AMG impresses with its athletic appearance and distinctive exterior and interior design. The model's standard specification also includes innovative LED High Performance headlamps.
"The new CLS 63 AMG continues the success story of the previous models, the CLS 55 AMG and CLS 63 AMG, which have delighted our customers all around the world since 2004", according to Ola Källenius, Head of Mercedes-AMG GmbH. "The CLS 63 AMG is a unique high-performance car – it sets new standards in design, performance and efficiency."

Like the S 63 AMG and CL 63 AMG, drivers of the CLS 63 AMG will benefit from an eight-cylinder powerhouse, designated internally as the M 157: the new AMG 5.5-litre V8 biturbo engine boasts a combination of innovative high-tech components which, in addition to spray-guided direct petrol injection with piezo injectors, also 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 AMG Performance package, these figures increase to 410 kW (557 hp) and 800 Nm. Both variants of the CLS 63 AMG achieve exceptional performance: acceleration from zero to 100 km/h takes 4.4 and 4.3 seconds respectively, and the top speed is 250 km/h (electronically limited).
The major difference between both power units is the increase in the maximum charge-air pressure from 1.0 to 1.3 bar. In addition, the CLS 63 AMG with the AMGPerformance package features a special high-quality carbon fibre engine cover.
Quantum leap: fuel consumption reduced by 32 percent

fasteddy:
Despite a significant performance increase compared with the previous model, which had a naturally aspirated AMG 6.3-litre V8 engine producing 378 kW (514 hp) and 630 Nm of torque, the new CLS 63 AMG is some 4.6 litres, or 32 percent, more economical – which represents a quantum leap forward. The NEDC fuel consumption of 9.9 litres per 100 km equates to a CO2 output of 232 g/km. Thanks to these figures, the new V8 Coupé from AMG not only undercuts all of its direct competitors in the small but refined four-door high-performance coupé segment, but is also more fuel efficient than significantly lower-powered vehicles. Both performance variants have identical fuel
consumption and CO2 figures.

Exclusive: AMG SPEEDSHIFT MCT 7-speed sports transmission
A major contribution towards achieving the unrivalled consumption figures has been made by the AMG SPEEDSHIFT MCT 7-speed sports transmission, a component used exclusively at Mercedes-AMG. Unlike a conventional automatic transmission, the MCT transmission does away with the torque converter; instead, it makes use of a compact, wet start-up clutch. Also fitted as standard equipment is the stop/start function: it is permanently active in the transmission's Controlled Efficiency ("C") mode, and switches the eight-cylinder engine off when the car comes to a stop. At the same time, "C" mode also means a "soft" accelerator response set-up with convenient and early gearshifts; moving off generally takes place in second gear. A green "ECO" symbol in the AMG instrument cluster shows the driver that the stop/start function is active.
The engine and transmission come across as much more agile in the "S" (Sport), "S+" (Sport plus) and "M" (Manual) modes; in addition, the stop/start function is switched off. In "S" and "M" modes, the engine management system partially suppresses the cylinders: interrupting ignition and injection under full load leads to even faster gearshifts than before. The highly emotional vocals are an appealing side effect of this lightning-fast process. An automatic double-declutching function and RACE START function are also included as standard.
Autonomously developed AMG RIDE CONTROL sports suspension

fasteddy:
The suspension, steering and braking system of the new CLS 63 AMG complement the high-tech drive system perfectly. The AMG RIDE CONTROL sports suspension, with steel suspension struts on the front axle and air suspension struts on the rear axle, as well as automatic level control, is enhanced further by an electronically controlled damping system; it automatically adjusts the damping characteristics depending on the driving conditions 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 press of a button.
The autonomously developed front axle, with a track width which is 24 mm wider, is the perfect match for the newly developed electromechanical AMG sports parameter steering. It not only features variable power assistance which adapts according to the suspension mode, but also contributes towards reducing fuel consumption by up to 0.3 litre (7 g CO2) in the ECE fuel cycle, since the steering assistance system only draws power when the vehicle is actually being steered. The 3-stage ESP® also has individual setting options – thereby providing a definite advantage when it comes to combining driving pleasure with absolute driving safety.
