Mercedes-Benz has releases full details for the 2012 CLS 63 AMG model.
2012 Mercedes-Benz 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. With a displacement of 5461 cc, the eight-cylinder engine develops a peak output of 525 hp and torque of 700 Nm.
In conjunction with the AMG Performance package, these figures increase to 557 hp and 800 Nm. Both variants of the Mercedes-Benz CLS63 AMG achieve exceptional performance: acceleration from 0-62 mph takes 4.4 and 4.3 seconds respectively, and the top speed is 155 mph, electronically limited.
Fuel economy on the standard CLS 63 AMG now comes in at under 10 liter/100 km (a noteworthy achievement) - with a 9.9 liters per 100 km rating on the European cycle (NEDC).
The acceleration is astonishing – 4.4 seconds to 100 km/h and 4.3 with the performance package. The top speed is electronically limited to 250 km/h, but with removing the limiter, CLS63 AMG will easily go over 300 km/h.
In addition, the vehicle fuel consumption of 28.5 mpg is an improvement of 32 percent over the previous model (all figures are provisional).

AMG V8 biturbo engine consuming 9.9 litres per 100 km: CLS 63 AMG - the benchmark in design, performance and efficiency
San Diego (USA) - Exciting design, ultimate performance and ground-breaking 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 con-sumption of 9.9 litres per 100 km (NEDC) represents an improvement of 32 percent compared with the previous model. 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."
As with 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. The weight-optimized AMG sports exhaust system with dual twin chrome tailpipes ensures a distinctive engine sound. 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 AMG Performance package features a special high-quality genuine carbon fibre engine cover.
Quantum leap: fuel consumption reduced by 32 percent
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 231 g/km. Thanks to these figures, the new V8 Coupé from AMG not only undercuts all of its direct competitors in the 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
An important 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", "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.
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.
Perfect deceleration even when driving extremely briskly is provided by the AMG high-performance braking system with 360 mm, internally ventilated and perforated brake discs all-round. Particularly resistant, motorsports-tested composite technology is used on the front axle. The optional AMG ceramic high-performance composite braking system with yet larger brake discs guarantees an even higher level of braking performance as well as lower unsprung masses. Good contact with the road, meanwhile, is provided courtesy of the titanium grey-painted, high-sheen AMG light-alloy wheels featuring a new triple-spoke design and fitted with 255/35 R 19 tyres on the front and 285/30 R 19 tyres on the rear. The AMG light-alloy wheels are manufactured using the weight-optimized flow-forming process, as already used on the SLS AMG.
The CLS 63 AMG is the first passenger car in the world to offer LED High Performance headlamps as standard, which combine the exciting colour elements of LED technology - similar to daylight - with the performance, functionality and energy efficiency of today's bi-xenon generation. 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 - including the active light function with LED for the first time too. 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.
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 top-of-the-range AMG model distinguishes itself from the other CLS variants with its distinctive bonnet, wider mudguards with "V8 BITURBO" logo and a specific AMG front apron with black painted cross member. Eye-catching features at the rear include the diffuser insert, the AMG spoiler lip on the boot lid, the AMG sports exhaust system with dual twin chrome tailpipes, and - as also featured on the SLS AMG - integrated rear foglamp. The AMG bodystyling perfectly matches the typical CLS outline, which is essentially characterised by the elegantly long proportions, the lateral dropping line and the muscular sports car-like shoulder line above the rear axle.
This philosophy also continues through consistently into the interior. All of the AMG-specific design and appointment features ideally supplement the redesigned CLS interior. The wrap-around effect in the cockpit, with its high line which sweeps from the driver's door over the instrument panel support and across to the front passenger door, is generously flanked by high-quality trim elements - available in black piano lacquer as standard in the top-of-the-range AMG model. Quality materials and workmanship meet the very highest of standards and help to guarantee a particularly exclusive atmosphere. The extensive range of standard appointments also includes AMG sports seats in nappa leather, a new three-spoke AMG Performance steering wheel with aluminium shift paddles and flattened top and bottom sections, and the AMG DRIVE UNIT with compact E-SELECT selector lever.
More than a dozen driving assistance systems on the new CLS help to prevent traffic accidents and reduce the severity of an accident. The Active Blind Spot Assist and the Active Lane Keeping Assist are new.
Active Blind Spot Assist warns the driver if the short-range radar sensors detect that there is a danger of collision if the vehicle is about to change lanes. Should the driver ignore the warnings and come 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 via the Electronic Stability Program ESP®, a yaw movement is created which counteracts the collision course.
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.
