The 2014 Mercedes CLS63 AMG gets a performance upgrade and introduces an entirely new model to its lineup with the model year 2014 CLS63 AMG S-Model which boasts the performance-oriented AMG 4MATIC all-wheel drive and comes equipped with the AMG 5.5-liter V8 biturbo engine generating a maximum output of 585 hp and 590 lb.-ft. of torque. The M157 AMG 5.5-liter V8 biturbo engine continues to be the absolute pinnacle of efficiency: the combination of high performance and low fuel consumption remains unrivaled by any other competitor in the segment worldwide.

Mercedes-Benz AMG is also premiering high-performance sedans and coupes with an AMG engineered version of the all-wheel-drive system known as 4MATIC. This system which is geared to driving dynamics offers customers a level of performance never seen in the segment.. Alongside the successful SUVs – ML63 AMG, GL63 AMG and G63 AMG – the E-Class and CLS-Class model ranges comprised of five unique models are now available from Mercedes- BenzAMGwith this performance AMG 4MATIC system as standard.

“The S-Models in particular represent the most attractive proposition in the segment,” notes Ola Källenius, CEO of Mercedes-AMG GmbH. “With its superlative power and torque ratings and the new performance-oriented AMG 4MATIC all-wheel drive, the CLS 63 AMG is without parallel in its Coupe and Shooting Brake variants. Our AMG 5.5-liter V8 engine remains the most efficient series production V8 engine in the world. The new, customized model variants provide greater scope than ever for individual solutions.”





Displacement 5.5-liter 5.5-liter
Rated power output 550 hp at 5,250 – 5,500 rpm 577 hp at 5,500 rpm
Peak torque 531 lb.-ft. at 1,750- 5,000 rpm 590 lb.-ft. at 2,000 – 4,500 rpm
Acceleration 0-100 km/h 3.7s (prelim) 3.6s (prelim)
Top speed 155 mph (electronically limited) 186 mph (electronically limited)

Acceleration 0-60 mph in 3.6 seconds clearly places the CLS63 AMG S-Model 4MATIC at the top of the competitive line-up. In addition to the increase in power, the special edge of the S-Model is also attributable in no small part to the performance-oriented all-wheel drive with a power distribution ratio of 33 to 67 percent (front/rear axle).

Perfect traction during acceleration effectively prevents slip-induced losses. The top speed stands at 186 mph (electronically limited).

On the new CLS63 AMG S-Model the AMG 5.5-liter V8 biturbo engine generates a maximum output of 577 hp and peak torque of 590 lb.-ft., an increase of 27 hp over the AMG Performance Package which was previously available as an option for the coupe. This enhanced performance and power results from adaptation of the engine application, an increase in peak pressure and a rise in the boost pressure from 0.9 to 1.0 bar. (At 550 hp and 531 lb.-ft. of torque, the CLS63 AMG model also boasts an increase of 32 hp over its predecessor.)

Despite added power and enhanced performance, all models offer high efficiency, low fuel consumption and low exhaust emissions. The AMG 5.5-liter V8 biturbo engine remains the most efficient series production V8 engine around – with substantially more displacement than its direct competitors.

AMG SPEEDSHIFT MCT 7-Speed sports transmission for a personal setup

Maximum individuality and custom-tailored dynamics are the strengths of the AMG SPEEDSHIFT MCT 7-Speed sports transmission. Four drive programs, “C” (Controlled Efficiency), “S” (Sport), “S+” (Sport plus) and “M” (Manual), provide each driver with a personal setup. In “C” mode the ECO start/stop function is active and shuts off the eight-cylinder engine when the car is at a standstill. In addition, the driver experiences smooth transmission characteristics with comfortable and early gearshifts. In “C” mode the car generally starts in second gear.

In the “S”, “S+” and “M” transmission modes the engine and transmission are significantly more agile and the ECO start/stop function is deactivated. Perfectly tailored to a sporty driving style is the partial suppression of the cylinders during gear changes. A brief and precisely defined retardation of ignition and injection under open throttle results in even faster and acoustically more emotional gearshifts. An automatic double-clutching function for downshifts and the RACE START function are also part of the standard features of the AMG SPEEDSHIFT MCT 7-Speed sports transmission.

Performance-oriented all-wheel-drive for maximum dynamics

The performance-oriented AMG 4MATIC all-wheel drive distributes the engine torque at a ratio of 33 to 67 percent (front/rear axle). The rear-biased torque split provides for signature AMG high driving dynamics and superlative driving pleasure. The 3-stage ESP® has been tailored specifically to the permanent all-wheel drive system. In “SPORT Handling” mode, the Torque Vectoring Brake performs selective braking interventions on individual wheels in the interest of high agility, thereby preventing unwelcome understeer during turn-in. A targeted brief brake intervention on the inside rear wheel results in defined cornering of the vehicle.

The AMG 4MATIC all-wheel drive provides optimal traction by using a multiplate clutch with a locking force of 37 lb.-ft., which particularly highlights the powerful transfer of torque on all four wheels.

The technical basis of the all-wheel drive is provided by a transfer case for the additional power take-off to the driven front axle. This transfer case is compactly integrated into the AMG SPEEDSHIFT MCT 7-Speed sports transmission and requires virtually no additional installation space. The torque is transferred from the power take-off via a propellershaft to the front axle. The power is sent from the front-axle differential to the front-left drive shaft via an intermediate shaft that passes through an encapsulated shaft duct in the engine oil pan. The compact and weight-optimized design results in a comparatively low additional weight for the all-wheel-drive system of only 155 lbs.

CLS63 AMG S-Model with limited-slip rear differential

Mercedes-AMG goes even one step further on the CLS63 AMG S-Model. In keeping with its philosophy of “Driving Performance,” a limited-slip rear differential is fitted on the rear axle as standard. This high-tech package increases traction even further. The effect is even better vehicle dynamics and more driving pleasure, in particular on the racetrack.

All CLS63 AMG models feature the AMG Adaptive Sports Suspension which featuresan electronically controlled damping system. The front axle employs a steel-spring suspension system, while the rear axle is fitted with a fully loadbearing air suspension system. Pressing the button marked with a shock absorber icon in the AMG DRIVE UNIT is sufficient to switch the electronics from “Comfort” to “Sport” or “Sport Plus”. The three-link front suspension has undergone further optimization for the S-Model and the CLS63 AMG with all-wheel drive. In conjunction with the newly developed aluminum axle components, these optimization measures result in markedly enhanced grip and agility combined with a high level of neutrality during fast cornering. The markedly more performance-oriented elastokinematics are exclusive to the S-Model, and offer the driver maximum neutrality and even better feedback and grip at the critical limits. The CLS63 AMG’s 2.4 centimeter (0.9″) wider track on the front axle offers substantially greater stability at higher cornering speeds and improved road feel. Increased negative camber on both axles additionally boosts lateral dynamics.

Electromechanical AMG speed-sensitive steering complements the vehicle’s set-up to perfection. The direct steering ratio of 14:1 ensures extremely agile handling in bends in conjunction with the variable power assist dependent on the selected suspension mode. The CLS63 AMG is fitted as standard with triple-spoke AMG light-alloy wheels painted titanium gray with a high-sheen finish. Tires in size 255/35 R 19 are mounted on 9.0 x 19 wheels at the front, while the 10 x 19 rear wheels carry size 285/30 R 19 tires. Only the high-performance S-Model features exclusive 10-spoke light-alloy wheels painted matte titanium gray with a high sheen rim flange.

Optional AMG ceramic high-performance composite brake system

As you would expect from an AMG vehicle, the CLS63 AMG is equipped with an AMG high-performance braking system. The front and rear axles sport ventilated and perforated brake discs in ample 14.2 inch format. The discs, which are subject to particularly high levels of stress and strain on the front axle, feature the compound rotor braking technology which has been tried and tested in the field of motorsport. Calipers with a silver painted finish and white AMG lettering and-incorporating six pistons (front) and four pistons (rear) provide for spontaneous, fading-resistant deceleration and the shortest stopping distances.

An AMG ceramic high-performance composite brake system is exclusively available for the S-Model as an optional feature – recognizable by the even larger 15.8 inches brake discs and the “AMG Carbon Ceramic” logo on calipers sporting a the signature bronze metallic paint finish. This ceramic system is around 40 percent lighter, reducing unsprung masses and enhancing handling, agility and ride comfort. The superior hardness of the ceramic brake discs leads to a longer service life and greater resistance to extreme stress and heat.

S-Model with subtly different design features

In terms of exterior design, the CLS63 AMG S-Model is distinguished from the other models by red brake calipers and the AMG logo on the trunk lid sporting an “S” in contrasting black. The the standard black Premium leather interior of the S-Model features gray contrasting stitching on the AMG sports seats, the center door panels, the door armrests, the steering wheel, the center console and is accented by silver seat belts. The rim of the AMG Performance steering wheel in black Premium leather is flattened at the top and bottom and boasts grip areas in Alcantara® . The front head restraints of the AMG sports seats exclusively feature the AMG crest embossed directly into the Premium leather. emblems. The AMG instrument cluster has some design cues unique to the S-Model and features an “S AMG” logo on the speedometer that is accompanied by red accents on the dials. Illuminated AMG door sill panels with white backlighting round off the exclusive range of equipment and appointments of the S-Model.

Bang & Olufsen BeoSound AMG high-end surround sound system

A particular highlight in the selection of optional equipment for all CLS variants is the Bang & Olufsen BeoSound AMG high-end surround sound system. Mercedes-Benz and AMG have created a high-end sound system with renowned Danish audio specialist Bang & Olufsen. The sound system is capable of Dolby Digital 5.1 playback and provides an exclusive music experience with unparalleled sound. The basis for this is not only the 1,200-watt amplifier and the 14 high-end speakers with neodymium drivers, but also the distribution of the music signals that is precisely controlled by the sound processor. This integrated digital sound processor (DSP) provides drivers with the option of selecting a special B&O sound menu on the COMAND system. In True Image™ mode individual sound settings for the front, center and rear can be selected. The effect: a realistic sound experience at the selected listening position. The “Sound Mode” menu also has various preset sound modes that allow choices between a high-end “Reference” studio sound and a spacious surround sound. While “Reference” puts the focus on the reproduction of the artist’s sound, the special surround sound mode delivers a spacious sound experience. In particular live recordings or concertos result in a unique panoramic sound in the vehicle without altering the naturalness of the recording.

Illuminated 50-watt tweeters with acoustic lens technology, arranged in the mirror triangle, add special highlights. High-end speaker covers in silver chrome with Bang & Olufsen logo additionally signal the exceptional position of the high-end surround sound system.

The market launch of the CLS63 AMG 4MATIC and the newthe CLS63 AMG SModel 4MATIC will commence in August.
