Mercedes-AMG combines Performance SUV with V8 expertise

April 5, 2017 • News

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.

“For us, the new GLC 63 4MATIC+ is a quite special vehicle. It is no easy job designing an SUV to be highly sporty and dynamic while at the same time offering inherent extreme driving stability and efficiency. This required us to put our heart and soul, along with our many years of SUV expertise, into the development of this vehicle. The result is an SUV that can be driven with high precision and agility and which, if required, is equally at home on a high-speed lap of the race track. With our V8 Biturbo engine, we hold a decisive USP in the Performance market. What is more, with SUV and Coupé, we offer the widest choice in the segment. Also, the technical closeness to our sports cars is visually underlined by the Panamericana grille, which was previously reserved for our AMG GT models,” says Tobias Moers, CEO of Mercedes-AMG GmbH.

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 bi turbo engine puts out 350 kW or 375 kW with a max. the 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 makes 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”, “Sports 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 the 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 “Sports 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 “Sports 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 comply 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 ELA Sto kinematics 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 ELA Sto kinematic 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 “Sports 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 shot 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 Sports 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.

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 motorsport 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 ingrained 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 unites 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.
