Mercedes-AMG combines performance SUV with the power of a V8, and AWD.

  • Mercedes-AMG GLC 63 4MATIC+ and GLC 63 4MATIC+ Coupé
Back in 1999, with the ML 55, Mercedes-AMG set a milestone – not just in its own 50-year history. For the combination of high-performance engine in the skin of an SUV opened up an entirely new market segment. Also with the new GLC 63 4MATIC+ and the GLC 63 4MATIC+ Coupé, Mercedes-AMG once again occupies an exceptional position in the marketplace. 
For the first time, a mid-size SUV is now also available with the powerful eight-cylinder biturbo in two output variants. The basis for this is provided by the AMG 4.0-litre V8 engine with 350 kW (476 hp) or 375 kW (510 hp) in the GLC 63 S and GLC 63 S Coupé variants. 
The Performance SUVs also feature air spring suspension with adaptive adjustable damping, AMG Performance 4MATIC+ all-wheel drive with fully variable torque distribution, a rear-axle limited-slip differential and a high-performance braking system. 
As a visual indication of their links with Mercedes-AMG sports cars, the new models sport the AMG Panamericana grille, which was previously reserved for the AMG GT family. 
In addition, the new models offer all the advantages of a Mercedes-SUV: ample room for passengers and luggage, comprehensive array of safety equipment and superior traction, also in the wet or in wintry road conditions.
The new Mercedes-AMG GLC 63 4MATIC+ and Mercedes-AMG GLC 63 4MATIC+ Coupé occupy exceptional positions in their respective markets on every front. They are the only vehicles in their segment to be powered by an eight-cylinder biturbo engine.
Mercedes-AMG thus meets the wishes of those customers who, also in a mid-size Performance SUV, are looking for a combination of superior power delivery along with a highly emotive, unmistakable engine sound.
Unique offering in the segment with V8 biturbo engine
SUV and Coupé are available as basic and S-model variants: the proven AMG 4.0-litre V8 biturbo engine puts out 350 kW (476 hp) or 375 kW (510 hp) with a max. torque of 650 or 700 Nm. The top speed is 250 km/h (electronically limited).
V8 biturbo closely related to engine in the Mercedes-AMG GT
The 4.0-litre eight-cylinder biturbo engine is already used in numerous AMG Performance vehicles. It is also installed in the AMG GT sports car with dry sump lubrication. A characteristic feature is that the two turbochargers are positioned not on the outside of the cylinder banks, but inside the cylinder "V". 
The main advantages of this design are the compact engine construction, optimal response and low exhaust gas emissions. One mechanic assembles each engine in the engine shop in Affalterbach according to the "one man ‑ one engine" principle.
Short shift times, high efficiency: the AMG SPEEDSHIFT MCT

9-speed transmission
The new GLC 63 4MATIC+ and GLC 63 S 4MATIC+ feature the AMG SPEEDSHIFT MCT 9-speed transmission, which made its debut in the Mercedes-AMG E 63 4MATIC+. The driver benefits from extremely short shift/response times. Fast multiple downshifts and the double-declutching function make for a highly emotive gearshift experience. A start-off wet clutch replaces the torque converter. This saves weight and optimises the response to the driver's accelerator pedal input, particularly on acceleration and during load changes.
AMG Performance 4MATIC+ variable all-wheel drive
After the E-Class from Mercedes-AMG, the GLC, too, now comes with AMG Performance 4MATIC+ all-wheel drive. This intelligent system unites the advantages of different drive concepts: the fully variable torque distribution to the front and rear axles ensures optimal traction right up to the physical limit. 
The driver is also able to rely on high driving stability and handling safety under all conditions, both in the dry and in the wet or in snow. The transition from rear-wheel to all-wheel drive and vice versa is seamless, because intelligent control is integrated into the overall vehicle system architecture.
An electromechanically controlled clutch connects the permanently driven rear axle fully variably to the front axle. The best possible torque distribution is continuously computed according to the driving conditions and driver's input. Transitions are seamless and based on a sophisticated matrix. Alongside traction and lateral dynamics, the all-wheel drive also improves the longitudinal dynamics for even more powerful acceleration.
For a personalised experience: AMG DYNAMIC SELECT drive programs
The four AMG DYNAMIC SELECT drive programs "Comfort", "Sport", "Sport Plus" and "Individual" allow the driver to extensively influence the characteristics of the GLC E 63 4MATIC+. This modifies key parameters, such as the response of engine, transmission, suspension, steering, ESP® and all-wheel drive. 
Independently of the DYNAMIC SELECT drive programs, the driver has the option of pressing the "M" button to switch directly to manual mode, in which gearshifts are executed exclusively using the shift paddles on the steering wheel. The suspension settings can also be specially selected if required.
"Comfort" is the balanced drive program with a comfort-oriented suspension and steering set-up as well as a fuel-efficient powertrain configuration with early upshifts – including smooth gearshifts and a restrained engine sound. The ECO start/stop function and coasting function are activated. 
This is how it works: When the driver releases the accelerator in a speed range between 60 and 160 km/h, the clutch of the MCT transmission opens and the engine is decoupled from the powertrain. The electronics lower the engine speed to idle and driving resistance is reduced by the compression and friction forces of the engine on overrun.
The DYNAMIC SELECT "Sport" and "Sport Plus" drive programs are designed for high driving dynamics. This results from an agile accelerator pedal characteristic with direct set-up and emotively appealing gearshifts with shorter shift times and double-clutching function on downshifts. The increased idle speed in "Sport Plus" also enables especially fast pull-away and acceleration from rest.
The GLC 63 S 4MATIC+ has an additional "RACE" drive program, in which all the parameters are configured for maximum performance. With a total of five drive programs, the Performance SUV once again offers the widest choice in the segment.
Exhaust system with flap technology for variable engine sound
The as-standard typical V8 engine sound comes courtesy of an exhaust system with flap technology. It is controlled by a map and automatically operated depending on the AMG DYNAMIC SELECT drive program, the power demanded by the driver and the engine speed. Optionally available is the Performance exhaust system, which allows the sound to be modulated at the press of a button. In any case, the exhaust systems are so designed that all noise limits are complied with irrespective of the flap position.
Specific suspension for maximum lateral and longitudinal dynamics
The agility, highly dynamic lateral acceleration and maximum grip of the new models are also thanks to the new AMG suspension with fully supporting multi-chamber air suspension, which ensures exceptionally high levels of camber stability, driving dynamics and steering precision.
The front axle features a four-link design with special steering knuckles, optimised elastokinematics and radial brake connections. Independent wheel control and wheel suspension elements enable higher lateral acceleration with minimal torque steer.
The concept for the rear axle was carried over from the E 63 4MATIC+ and specially matched to the requirements of the GLC. The model-specific multi-link concept impresses with highly precise wheel control and increased stiffness. 
The AMG-specific rear axle carrier makes the wider track possible in comparison with the GLC from Mercedes-Benz, while the contact surfaces of the wheel bearings have also been moved further outwards. Other measures include AMG-specific wheel carriers, stiffer elastokinematic tuning and higher negative camber.
Individual driving experience thanks to three-chamber air suspension system
Thanks to a sporty spring and damper set-up and continuously variable damping, the new three-chamber air suspension system combines exemplary driving dynamics with excellent road roar and tyre vibration characteristics. 
The stiffness of the air springs can be adjusted over a wide range by activating or deactivating individual air chambers, making for perceptibly enhanced comfort and handling.
There are three degrees of spring tuning, depending on the selected drive program and current driving status. The spring rate is hardened automatically in the event of sudden load changes, fast cornering, heavy acceleration or heavy braking, this effectively reducing roll and pitch while stabilising the Performance SUV.
The adaptive damping can be set in three stages – "Comfort", "Sport" and "Sport Plus" – to choose between relaxed comfort on long journeys and maximum sportiness. The rebound and compression levels are adjusted independently of each other, and the freely programmable maps permit a wide spread between minimum and maximum damper force. The difference between the comfortable and sporty suspension settings is made more refined and is clearly perceptible – depending on driving style.
The GLC 63 4MATIC+ is shod as standard with 10-spoke light-alloy wheels 8.0 J x 19 (front) and 9.0 J x 19 (rear) painted in titanium grey with a high-sheen finish and with tyres of size 235/55 R 19 (front) and 255/50 R 19 (rear). The dimensions for the GLC 63 S 4MATIC+ are 265/45 R 20 (front) and 295/40 R 20 (rear) on 5-twin-spoke light-alloy wheels painted in titanium grey with a high-sheen finish in 9.5 J x 20 (front) and 10.0 J x 20 (rear). There are other, optional wheel/tyre combinations as well as forged wheels, up to sizes of 265/40 R 21 on 9.5 J x 21 on the front axle and 295/35 R 21 on 10.0 J x 21 wheels on the rear axle.
Rear-axle limited-slip differential: optimal traction under all conditions
For improved traction and driving dynamics, the GLC 63 4MATIC+ comes with a mechanical rear-axle limited-slip differential, while the GLC 63 S 4MATIC+ uses an electronic rear-axle limited-slip differential. Both differentials reduce the slip on the inside wheel when cornering, without control interventions by the brakes. 
The result: allows the driver to accelerate out of corners earlier thanks to the improved traction. The vehicle remains more stable when braking from high speed, while the limited-slip differential also improves traction from rest. Overall, the rear axle has been specially matched to the higher driving dynamics of the new Performance SUVs.
The greatest benefit of the electronic rear-axle limited-slip differential is the even more sensitive and faster control, which pushes the critical threshold higher, making it even easier to drive at the vehicle's limits. The three-stage ESP® with "ESP ON", "ESP SPORT Handling Mode" and "ESP OFF" settings works in perfect unison with the rear-axle limited-slip differential and is optimally tuned to the outstanding dynamics.
Precise, agile handling: speed-sensitive sports steering
The electromechanical, speed-sensitive sports steering makes for precise, agile handling with authentic feedback. The driver benefits from the variable steering ratio and optimised response.
The steering also features variable power assistance with the two modes "Comfort" and "Sport". The power steering is dependent not only on the vehicle's speed, but also on the instantaneous lateral acceleration, selected AMG DYNAMIC SELECT drive program and setting of the adjustable damping.
With 360-millimetre perforated and internally ventilated brake discs at front and rear, the high-performance braking system on the GLC 63 4MATIC+ ensures short stopping distances along with excellently controllable braking force. The GLC 63 S 4MATIC+ is fitted with 390-millimetre compound brake discs at the front to allow for the increased performance.
Expressive front end with Panamericana grille
A striking characteristic of the exterior design is the expressive front end: the new GLC 63 4MATIC+ is the first Mercedes-AMG Performance vehicle to feature the Panamericana grille, which was previously reserved for the AMG GT family of sports cars. 
This design statement affirms the consistently dynamic design of the new Performance SUV and Coupé. A wide front apron inspired by the design of a jet wing, with a large front splitter, impressively embodies the power of the new models. 
By dispensing with a fine-meshed grille, it gives a view of the cooling technology – a typical attribute from the world of motor sport and a further differentiation from the other GLC models. Wider wheel arch claddings at front and rear lend emphasis to the muscular looks.
The new side sill panels make the SUV and Coupé appear to sit lower on the road while elongating the overall lines. On the S-model variant, matt iridium silver inserts make for a distinctive appearance. The muscular rear end is dominated by the wide rear apron and diffuser in grained black. The trim on the diffuser board of the S-model variant is in matt iridium silver. The SUV is for the first time provided with a spoiler lip on the roof, while the spoiler lip on the Coupé is familiar from the GLC 43 4MATIC. The exhaust system is terminated by two high-gloss chrome-plated twin tailpipe trims.
Interior also with a consistent focus on driving dynamics
The interior underscores the leadership ambition of the new mid-size Performance SUVs in terms of driving dynamics. Driver and front passenger are enclosed as standard in sports seats in ARTICO man-made leather, combined with DINAMICA microfibre, which unite excellent lateral support with functional ergonomics tailored to the job of driving.
The instrument panel is trimmed in black ARTICO man-made leather with contrasting topstitching. The high-grade look is underlined by aluminium trim. The touchpad is flanked by the AMG DYNAMIC SELECT switch and numerous AMG-specific controls, such as the button for the 3-stage AMG RIDE CONTROL suspension, 3-stage ESP® or optionally the button for the AMG Performance exhaust system with flap control.
The S-model variant comes with an even more extensive equipment package, including a Performance steering wheel in black nappa leather / DINAMICA microfibre, AMG badges in the front head restraints in combination with leather appointments and AMG instrument cluster with red highlights.
Exclusive optional extras
The AMG Performance Studio offers technical and design highlights to make the Mercedes-AMG GLC 63 4MATIC+ even sportier, more exclusive and more individual. The following provides just a selection:
  • AMG Performance exhaust system with flap control at the push of a button
    • Greater differentiation of the sound characteristics by two additional exhaust flaps

Exclusive "Edition 1" special model at market launch
The SUV and Coupé variants of the Mercedes-AMG GLC 63 4MATIC+ and GLC 63 S 4MATIC+ are also available at launch as an "Edition 1" special model: the exclusive combination of equipment details turn the special model into the flagship of the range.
In both body variants, the Night package in high-gloss black enhances the racing-inspired looks. The sports stripes on the sides of the vehicle are in matt yellow or graphite grey, depending on the paint colour. The matt black 21-inch cross-spoke forged wheels are provided with highlights in the form of yellow or high-sheen rim flanges. The Aerodynamics package, too, draws its inspiration from the world of motor sport.
The racing feel is carried over into the interior. The sports seats are upholstered in black nappa leather and reprise the colour yellow in the contrasting topstitching of the specific diamond pattern. Black nappa leather with yellow contrasting topstitching also enhances the door centre panels, armrests and centre console.

Geneva debuts the next all AMG model, the four door AMG GT Concept.

  • AMG Future Performance: Sports car brand presents hybrid show car
As part of its 50th anniversary Mercedes-AMG is this year celebrating not only the successful past and present; above all it is looking forward. 
With the show car Mercedes-AMG GT Concept the sports car and performance brand is giving an indication of the alternative drive configurations AMG is designing. 
Over and above this the four-door coupé heralds the further extension of the AMG GT family. The third model series after the SLS AMG and AMG GT is now being completely autonomously developed at the company’s headquarters in Affalterbach. 
The designation and fundamental design elements on the front and tail end denote the family affiliation to the AMG GT. The"EQ Power+" identifier on the mirror cam indicates the increased performance that can be expected from hybridisation at AMG.
"With the Mercedes-AMG GT Concept we are giving a preview of our third completely autonomously developed sports car. And extending the attractive AMG GT family to include a four-door variant. 
Plus the GT Concept - like the AMG Hypercar, which we are presenting at the International Motor Show in Frankfurt - illustrates how we are defining performance of the future at AMG. 
Impressive driving dynamics coupled with high efficiency, resulting from an innovative drive system and tailored to the vehicle segment in question – that is Future Performance made by AMG. 
With our AMG GT Concept that means a combination of an ultramodern V8 petrol engine and a high-performance electric motor. Both intelligently networked and with a modular battery concept with a combination of extremely powerful yet light batteries. This performance hybrid powertrain offers an impressive electric range and the opportunity to generate a system output of up to 600 kW in its last level of development. 
It covers the sprint from 0-100 in less than three seconds – which corresponds to a super sports car level" says Tobias Moers, Chairman of the Board of Management of Mercedes-AMG GmbH.
The four-door sports car from Affalterbach will seamlessly continue the success story of the AMG GT. The dynamic fastback will also be highly suitable for everyday use thanks to the large tailgate and the variable interior and luggage compartment. 
The new coupé thus blends the high functionality of the performance cars with the sportiness of the AMG GT sports cars. The show car gives a sneak preview of the exterior design of the coming series production model.
Muscular proportions, large volume and clear surface designs
With the aid of the unmistakeable design idiom with a deeply drawn bonnet and powerfully raked windscreen, the AMG GT Concept is recognisable at first glance as a genuine AMG GT. 
The exterior design stands out with extremely muscular proportions, a large volume plus sensuous and simultaneously reduced surface styling. The concept car represents the design philosophy of Sensual Purity and lends it the added performance characteristic of AMG.
"The GT Concept embodies the most extreme expression of our design idiom and underlines anew the autonomous profile of AMG as a performance brand", said Gorden Wagener, Chief Design Officer Daimler AG. "Through perfect proportions it creates a puristic design with the emphasis on its surfaces, featuring sensuous shapes and is hot and cool at the same time."
Advanced AMG GT characteristics
The Panamericana grille with vertical ribs painted red on the sides, the new configuration of the extremely slim main headlamps and the side air gills with their dominant design in the front apron are hallmark AMG GT design characteristics which have been advanced to a new level here and express pure power. 
The bonnet reaching right to the wheel arches underscores the decidedly sports car genes together with the two power domes. This is also expressed in the extravagant paintwork in the colour shade hot red with a finish that shimmers in the light like liquid metal thanks to a special formulation.
The Mercedes-AMG principle that fascination is always linked with function also applies to the study. Proof of this includes the moving radiator shutters in the centre and side air intakes, which improve the aerodynamic and thermal efficiency and are inspired by the active air control system AIRPANEL in the AMG GT R.
Pioneering: "Nano active fibre technology" for daytime running lamps and tail lamp showcasing
With the "nano active fibre technology" Mercedes-AMG is presenting future-oriented daytime running lamps for the first time. This is produced by a special bright light system in a freely styled light cord. The three-dimensional illumination effect lends the AMG GT Concept an autonomous light signature, which is flanked by numerous further measures in the high-tech headlamp. The turn signal light function is integrated at the top edge. The serial turn signal pulse ("flashing light indicator") has again been enhanced and impresses with its extremely rapid sequence. Two tubular rod lights illuminate the road surface directly in front of the car and constitute the driving light together with the large LED main headlamp and its lens system. A golden sail-shaped badge supplements the individual impression, and a red AMG logo denotes attention to detail. Overall the front headlamp is a three-dimensional multilayered high-tech component which underscores the technical standards of the performance study with features in gunmetal grey and brushed aluminium.
Rear assembly in hallmark AMG GT look
The width-biased rear assembly also cites the unmistakeable AMG GT look with the extremely slim horizontal tail lamps and the shape of the tailgate. The tail light also has the new light technology, which is located beneath the three-dimensional lens of the rear lamps. A ribbed cooling module is integrated into the lens to guide the waste heat to the exterior.
Further design elements at the tail end are the wide carbon-fibre diffuser curved downwards at the sides and the centrally arranged tailpipe trim reminiscent of the Mercedes-AMG GT R.
The crouched, dynamic greenhouse with its steeply sloping roof line and the slim layout of the frameless side windows emphasise the dynamic forwards thrust of the AMG GT Concept when seen from the side. The tapered side drop and the broad rear shoulder in the area of the flared wheel arches reinforce the muscular expression. The function of the exterior mirrors on the study is taken care of by aerodynamically favourable miniature cameras, known as mirror cams. The roof, the A-wing of the front spoilers, the rear diffuser and the side sill panels in high-quality yet light carbon fibre make the connection with motorsport.
The very expressively styled wheels in a fine-spoke design allow a good view of the AMG ceramic high-performance compound brake. The brake callipers are painted in a bronze colour and bear the "AMG Carbon Ceramic" lettering.
AMG Future Performance: forward-thinking hybrid drive system
The drive system of the AMG GT Concept represents a completely new development. With the SLS AMG Electric Drive back in 2010 Mercedes-AMG proved that a super sports car with a battery/electric drive system can be realised – with astounding performance and maximum driving pleasure. Formula 1 driving dynamics and efficiency are promised by the planned AMG Hypercar. It gives a sneak preview of the ultimate that is currently feasible with hybrid technology.
Based on this experience, the AMG GT Concept study conveys an impression of the alternative drive configurations Mercedes-AMG is designing. Following the AMG brand pledge "Driving Performance" Mercedes-AMG will in future develop segment-specific hybrids with an impressive performance gain which not only ensure an incomparable output, but also maximum efficiency.
Innovative combination of combustion engine and electric motor
After the Formula 1 vehicle, the show car is the second AMG model to bear the new designation "EQ Power+", which all performance hybrids from Mercedes-AMG will be given in future.
The performance hybrid system combines the powerful 4.0-litre V8 biturbo engine with an additional powerful electric machine and thus ensures extremely immediate response and offers an extraordinarily high system performance. The sprint from 0-100 km/h can be mastered at a super sports car level by the AMG GT Concept in less than three seconds.
Characteristically for the brand, the maximum Driving Performance in the form of extremely high driving dynamics is the Affalterbach engineers´ focus. This is why the AMG GT Concept has a balanced axle load distribution. The fully variable AMG performance 4MATIC+ all-wheel drive is also supported by the electric motor. It drives the rear wheels directly and has the effect of an additional booster. Besides this, according to the principle of Torque Vectoring, every wheel can be allocated torque individually. The result: the driver directly experiences a tangible increase in performance.
The scalable performance battery
It is set to extend the portfolio of Daimler AG to include a performance-oriented alternative: The energy storage unit is more powerful than conventional hybrid batteries, but at the same time more compact and lighter – further proof of the systematic way in which the AMG Lightweight Performance Strategy is being implemented. On a modular basis the system is scalable upwards, so that the performance and capacity of the battery can be adjusted to meet specific requirements of customers or certain markets.
The charging of the battery during the journey occurs on the one hand via brake recuperation, but on the other hand also with the aid of the combustion engine if the battery charge has dropped beneath a certain threshold value.
Power from two drive systems: performance operating strategy from Formula 1
The operating strategy of the AMG GT Concept is derived from the hybrid powerpack of the MERCEDES PETRONAS AMG Formula 1 racing car. As in the champions league of motorsport, the battery is also charged whilst the vehicle is being driven so as always to have the full amount of electrical power available – and for instance to be able to accelerate out of bends in a flash with full thrust. The transfer of knowledge works through the cooperation with the development engineers at Mercedes-AMG HPP (High Performance Production GmbH), meaning that the operating strategy of future performance hybrids from AMG will be perceptible all the time.
The electric drive unit
Three operating modes can be preselected via the electric drive unit: the AMG GT Concept either drives purely electrically or only with the combustion engine or it optimally combines both drive sources with one another as a hybrid.
The manifestation of the operating strategy, the definition of the drive programs and fundamental hybrid components are exclusive AMG developments, which all pursue the same aim: to facilitate a unique dynamic driving experience with Driving Performance in future, too.
