The top-of-the-range version of the new CLS four-door coupe is equipped with the newly developed AMG V8 biturbo engine, featuring a peak output of up to 557hp and 590 lb-ft of torque, as well as the AMG SPEEDSHIFT MCT 7-speed sports transmission. On top of this, the vehicle's fuel consumption of 24mpg US represents an improvement of 32 per cent compared with the previous model (all figures provisional).
The combination of an AMG RIDE CONTROL sports suspension with an 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. The model's standard specification also includes innovative LED High Performance headlamps.
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-liter V8 biturbo boasts a combination of innovative high-tech components which, in addition to spray-guided direct fuel injection with piezo injectors, also include an aluminum crankcase, four-valve technology with camshaft adjustment, air/water intercooling, generator management and stop/start system.
With a displacement of 5461cc, the eight-cylinder engine develops a peak output of 525hp and torque of 516 lb-ft. In conjunction with the AMG Performance package, these figures increase to 557hp and 590 lb-ft.
Both variants of the CLS 63 AMG achieve exceptional performance: acceleration from 0-62 mph takes 4.4 and 4.3 seconds respectively, and the top speed is 155mph (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 AMG Performance package features a special high-quality carbon fiber engine cover.
Contact with the road is provided by titanium grey-painted AMG wheels featuring a new triple-spoke design and fitted with 255/35 R19 tires on the front and 285/30 R19 on the rear.
Like the SLS AMG, the CLS 63 AMG is also fitted with doors featuring a full aluminum construction. They consist of deep-drawn aluminum panels with extruded sections, and are around 53 lb lighter compared with conventional steel doors. In addition, the hood, front fenders, trunk lid, parcel shelf, various support sections as well as major parts of the chassis and engine are all made from aluminum.
The CLS 63 AMG is the first passenger car in the world to offer LED High Performance headlamps, which combine the exciting color elements of LED technology - similar to those of daytime running lamps - with the performance, functionality and energy efficiency of today's bi-xenon generation. Fitted as standard, for the first time ever this new light system provides the Intelligent Light System already proven in Mercedes models fitted with bi-xenon headlamps in combination with LED technology. The headlamps, with their 71 LED lamps in total, underline the unmistakable appearance of the CLS 63 AMG. The light specialists from Mercedes-Benz have for the first time been able to use LED technology in the Adaptive Highbeam Assist, resulting in an entirely new level of safety when driving at night.
In contrast to the first vehicles equipped with LED headlamps, no compromises are now necessary with respect to the functionality and performance of the lighting technology. There are further arguments for the new, LED-based lighting technology: the average operating life of an LED is around 10,000 hours, around five times longer than that of a xenon light; moreover, LED headlamps most closely approximate the color temperature of daylight. This means that LED light is in keeping with normal human perception patterns. Studies have shown that the closer the color of artificial light comes to daylight, the less strain there is on the eyes. With a color temperature of 5500 kelvin, LED light is closer to daylight (6500 K) than xenon light (4200 K). The LED daytime driving lights specific to AMG are also presented in two characteristic light strips integrated into the AMG front apron.
When viewed from the front, the new CLS 63 AMG evokes associations with the SLS AMG - the radiator grille in particular, with its large Mercedes star and wing-shaped horizontal slats, appears to have been inspired by the gullwing.
The CLS distinguishes itself from the other variants with its distinctive hood, wider flares with "V8 BITURBO" logo and a specific AMG front apron with black painted crossmember.
Eye-catching features at the rear include the diffuser insert, the AMG spoiler lip on the trunk lid, the AMG sports exhaust system with dual twin chrome tailpipes, and - as also featured on the SLS AMG - integrated rear foglamp. The AMG body styling perfectly matches the typical CLS outline, which is essentially characterized by the elegantly long proportions, the lateral dropping line and the muscular sports car-like shoulder line above the rear axle.
