The CLS 55 AMG already had no direct competitors back in 2004. The first four-door performance Coupe inspired other automotive manufacturers and over the years has come to be copied many times. The successor model presented in 2006, the CLS 63 AMG with an AMG 6.3-litre V8 engine, and the current CLS 63 AMG with the 5.5-litre V8 biturbo engine available since 2011, have consistently continued this strategy.
The AMG 5.5-litre V8 biturbo engine impresses with a combination of direct petrol injection with spray-guided combustion, piezo injectors, biturbocharging, air/water intercooling, generator management and ECO start/stop function. The eight-cylinder engine is the embodiment of pure dynamism and high efficiency: offering power output and torque levels of 525 hp and 700 Nm respectively, the effortless superiority of the CLS 63 AMG Shooting Brake can be enjoyed by the driver over every single kilometre. In conjunction with the Edition 1 these figures are pushed to 557 hp and 800 Nm. Both variants offer driving performance of the highest calibre: accelerating from zero to 62 mph takes 4.4 and 4.3 seconds respectively, and the top speed is 155 mph (electronically limited).
Despite offering dynamism similar to that of a sports car, the consumption figures are maintained at a low level. Fuel consumption of 27.9 mpg (NEDC) corresponds to a CO2 output of 235 g/km and is identical for both power units. The driving experience in the CLS 63 AMG Shooting Brake is characterised by high levels of agility through all engine speed ranges. The absolutely effortlessly superior power delivery can also be heard by the driver too: the sports exhaust system with chrome twin tailpipes emits a sonorous eight-cylinder engine sound typical of AMG.
The AMG eight-cylinder engine is not the only highlight – the AMG SPEEDSHIFT MCT 7-speed sports transmission also boasts exciting levels of performance and efficiency. Equipped with four individual transmission modes as well as automatic double declutching and RACE START functions, its power delivery is characterised by responsiveness and maximum variability. In "Controlled Efficiency" (C) mode, the ECO start/stop function is always enabled and switches the eight-cylinder engine off when the vehicle is at a standstill. In "S" (Sport), "S+" (Sport plus) and "M" (Manual) transmission modes, the engine and transmission are significantly more responsive: short, precisely defined interruptions of ignition and injection result in faster gear changes under full load.
The suspension, steering and braking system of the CLS 63 AMG Shooting Brake 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 effect of this is 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 three-stage ESP® with SPORT Handling mode also enables three individual control strategies to be selected at the press of a button.
The elegant design idiom of a vehicle design is combined in the CLS 63 AMG Shooting Brake with a distinctly sporty sense of dominance. Its high levels of performance are visibly expressed in such elements as the powerful AMG front apron with cross strut finished in high-gloss black, the AMG radiator grille with single slat and the AMG-specific design of the bonnet.
Further dynamic highlights also include the original, broader front wings with "V8 BITURBO" lettering, the AMG-specific rear apron with diffuser look and the AMG sports exhaust system with two chrome twin tailpipes. High-performance LED headlamps including Intelligent Light System and adaptive Highbeam Assist are fitted as standard.
From the quality of materials and workmanship through to the exclusive atmosphere, the interior of the CLS 63 AMG Shooting Brake meets the very highest of standards. AMG sports seats in Nappa leather with multicontour seat and memory functions, AMG Black Piano lacquer trim and the AMG-specific analogue clock featuring an IWC design all help to create a unique aura. The driver is also kept perfectly and fully informed too thanks to the AMG instrument cluster with AMG main menu including RACETIMER and AMG start-up screen.
The transmission modes, suspension setup, ESP® functions and the AMG program can all be configured via the AMG DRIVE UNIT with E-SELECT selector lever – a special feature exclusive to AMG – which is integrated into the centre console and angled towards the driver. Visually striking, ergonomic and reassuringly tactile: the AMG Performance steering wheel in Nappa leather features a three-spoke design with flattened top and bottom sections, perforated leather finish and silver coloured aluminium shift paddles. A newly introduced feature on all AMG vehicles is the chrome-look electronic key with AMG emblem.
