- AMG characteristic design features for the exterior and interior
Hot on the heels of the recently introduced GLC AMG SUV models comes their Coupé counterparts. These models now complete the successful midsize series from Mercedes-AMG and sets another highlight in the model portfolio with its combination of dynamic elegance and characteristic AMG features. Striking proportions and exciting surfaces underline its unmistakable appearance, complemented by the high-quality interior.
There are two powerful model variants to choose from: The GLC 63 S E PERFORMANCE Coupé is the brand’s first performance hybrid SUV coupé with 500 kW system output at the start. There is also the entry-level model, the GLC 43 4MATIC Coupé with 310 kW power and a short-term boost of 10 kW via the belt-driven starter generator (RSG). The extensive standard equipment with rear-axle steering, all-wheel drive, AMG SPEEDSHIFT MCT 9G transmission with wet starting clutch and AMG RIDE CONTROL suspension with adaptive damping supports the dynamic driving experience.
The hybrid powertrain exclusive to Mercedes-AMG in the GLC 63 S E PERFORMANCE is a technical masterpiece. It combines the AMG 2.0-litre turbo engine with an Electric Drive Unit (EDU) on the rear axle for an exhilarating driving experience with high efficiency. In addition to the clearly noticeable thrust, the independent hybrid layout also ensures a balanced weight distribution – benefiting driving dynamics and handling in equal measure. The immediate response of the electric drive on the rear axle, the fast torque build-up and the rapid power delivery are very special features.
Depending on the drive program and driving conditions, the electric motor boosts power and torque according to the situation, thus conveying either a particularly comfortable or a performance-oriented driving experience. Electric-only mode is also possible. The electric powertrain and the high-performance battery with 400 volts are AMG exclusive in-house developments. Just like in Formula 1™, the battery is specifically designed for fast power output and draw with innovative direct cooling of the cells. The combined system output is 500 kW, the combined maximum system torque 1020 Nm.
Another highlight is the fully variable AMG Performance 4MATIC+ all-wheel drive for even more driving pleasure. Added to this is the standard active rear-axle steering, which combines agility and stability.
Characteristic AMG elements for the exterior and interior ensure a sporty, refined appearance
On the outside and inside, numerous AMG-specific details underscore the dynamic and high-quality character of the new Mercedes-AMG GLC variants in equal measure. The sporty silhouette with a flowing transition to the rear is the main feature of the new Mercedes‑AMG GLC Coupé. The headlights connect to the top of the AMG-specific radiator trim and thus emphasise the width of the vehicle. The AMG front apron in jet wing design with large air inlets, vertical fins and additional flics sets striking, independent accents. Precise side edges emphasise the sporty proportions and the powerful wheel arches.
The two-part taillights visually widen the rear view with a black, dark red connecting element. The AMG‑specific rear apron in a diffuser look (GLC 43) or with an additional diffuser board (GLC 63 S) as well as the two double tailpipe trims (round on the GLC 43, trapezoidal on the GLC 63 S) reinforce the powerful impression.
In the interior, AMG seats in ARTICO man-made leather/MICROCUT AMG microfibre with distinctive graphics and upholstery add a sporty touch. Optional leather and nappa leather upholstery with embossed AMG crest in the front head restraints is available. The AMG Performance seats are also available as an option.
The AMG Performance steering wheel in nappa leather (GLC 43) or nappa leather/MICROCUT microfibre (GLC 63 S) is also fitted as standard. It is flattened at the bottom, perforated in the grip area and equipped with silver-coloured aluminium gearshift paddles. The two round AMG steering wheel buttons allow fast and unerring operation of various dynamic driving functions and of the AMG DYNAMIC SELECT drive programs. The sporty-luxurious atmosphere is rounded off by AMG sports pedals, AMG floor mats and illuminated door sill panels with AMG lettering.
The MBUX infotainment system includes various AMG-specific displays and functions. These include special displays in the instrument cluster, on the portrait-orientation multimedia central display in the centre console and on the optional head-up display. The AMG exclusive “Supersport” style offers the option of displaying various contents via a vertical structure. This includes a set-up menu that displays the current settings of the suspension or transmission. In addition, the driver can have a navigation map or consumption data displayed in “Supersport” style.
Also integrated is AMG TRACK PACE (standard in the GLC 63 S, optional for the GLC 43), the data logger for use on the racetrack. The software records more than 80 vehicle-specific data such as speed, acceleration and steering angle ten times per second while driving around a racetrack. Also informative are the display of lap and sector times as well as additional training and analysis tools.
AMG 2.0-litre four-cylinder with electric exhaust gas turbocharger
At the heart of the new Mercedes-AMG GLC models is the AMG 2.0-litre four-cylinder engine, which combines innovative technologies and high performance with exemplary efficiency. The power unit remains true to a tradition typical of the brand: Not only was it developed entirely at the company’s Affalterbach site, but it is also installed there in accordance with the “One Man, One Engine” principle. In doing so, Mercedes-AMG combines the craftsmanship of its highly qualified employees with the latest production methods of Industry 4.0 and a high degree of digitalisation.
The M139l engine, as it is known internally (l for longitudinal installation), is the only production engine in the world to date that is turbocharged with an electric exhaust gas turbocharger. The system is a direct derivative of the technology that the Mercedes-AMG Petronas F1™ Team has been using successfully in the premier class of motorsport for many years. The new form of turbocharging guarantees particularly spontaneous response across the entire rev range. This leads to an even more dynamic driving experience, while at the same time increasing efficiency.
The functional principle of the electric exhaust gas turbocharger in detail
An electric motor around four centimetres thin is integrated directly on the turbocharger shaft between the turbine wheel on the exhaust side and the compressor wheel on the intake side. This directly drives the shaft of the turbocharger and is electronically controlled, accelerating the compressor wheel before the exhaust gas flow takes over the drive conventionally.
This significantly improves the response directly from idle speed and across the entire rev range. The combustion engine responds even more spontaneously to accelerator pedal input, while the entire driving feel is significantly more dynamic. In addition, the electrification of the turbocharger allows higher torque at low revs. This also increases agility and optimises acceleration from a standstill. Even when the driver lifts off the accelerator or brakes, the technology is able to maintain boost pressure at all times. This ensures a continuously direct response.
Powered by the 48-volt on-board electrical system, the electric exhaust gas turbocharger operates at speeds of up to 175,000 rpm, which enables a very high air flow rate. The turbocharger, electric motor and power electronics are connected to the combustion engine’s cooling circuit to create an optimal temperature environment at all times.
Compared to the GLC 43, however, the turbocharger in the GLC 63 S is significantly larger. This delivers a higher air flow rate and thus more power. In addition, the integrated electric motor is driven by the 400-volt high-voltage system.
The closed deck design of the M139l ensures high rigidity at low weight. This enables peak combustion pressures of up to 160 bar. The areas around the cylinders are largely closed, and the cover plate is only pierced by smaller channels for the coolant and engine oil. Another outstanding feature of the engine is the two-stage petrol injection. In the first stage, particularly fast and precise piezo injectors deliver the fuel into the combustion chambers at pressures of up to 200 bar. The second stage adds intake manifold duct injection with solenoid valves, which is needed to achieve the engine’s high specific power output.
GLC 43 offer 310 kW output and 500 Nm torque enable dynamic driving performance
In the 2.0-litre four-cylinder in-line engine, the innovative technology helps the Mercedes‑AMG GLC 43 4MATIC to achieve a rated output of 310 kW at 6750 rpm. The maximum torque of 500 Nm is available at 5000 rpm. Depending on the situation, the system also briefly provides an additional boost of 10 kW by the belt-driven starter generator (BSG). The second-generation RSG acts as a mild hybrid, providing this temporary power boost as well as functions such as gliding and recuperation for maximum efficiency. At the same time, the 48-volt technology also increases comfort, as the transitions between the start/stop function and the gliding mode function are almost imperceptible.
The GLC 43 4MATIC accelerates from a standstill to 100 km/h in 4.8 seconds. The top speed is electronically limited to 250 km/h.
GLC 63 S E PERFORMANCE with 500 kW system output and up to 1020 Nm system torque
The M139l produces 350 kW at 6725 rpm. This makes it the most powerful series-produced four-cylinder engine in the world. The maximum combustion engine torque of 545 Nm is available at 5250–5500 rpm. In the performance hybrid, the 2.0-litre engine is combined with a permanently excited synchronous electric motor, a high-performance battery developed in Affalterbach and the fully variable AMG Performance 4MATIC+ all-wheel-drive system. The system output of 500 kW and the maximum system torque of 1020 Nm enable impressive driving performance: Acceleration from standstill to 100 km/h takes just 3.5 seconds and only ends at an electronically governed 275 km/h.
The 150 kW electric motor is positioned at the rear axle, where it is integrated with an electrically shifted two-speed transmission and the electronically controlled limited-slip rear differential in a compact electric drive unit (EDU). Experts refer to this layout as a P3 hybrid. The lightweight high-performance battery is also located in the rear above the rear axle. This compact design has numerous advantages:
The electric motor acts directly on the rear axle and can therefore convert its power more directly into propulsion – for that extra boost when moving off, accelerating or overtaking. The inherent design of the electric motor means that its power can kick in straight away at full torque, making particularly agile starting possible. In addition, the driver immediately experiences a noticeable performance increase thanks to the integrated, electronically controlled limited-slip rear differential: the hybrid model accelerates out of bends with great agility.
If slip occurs at the rear axle, the drive power of the electric motor is also transferred to the front wheels as needed for more traction. The mechanical connection of the fully variable all-wheel drive makes this possible by means of the propeller shaft and drive shafts of the front wheels. The positioning at the rear axle improves the weight and axle load distribution in the vehicle. This forms the basis for the compelling handling.
The AMG concept offers very high recuperation efficiency, as the system allows only minimal mechanical and hydraulic losses from the engine and transmission. The automated two-speed transmission at the rear axle with its specially calibrated gear ratio ensures the spread from high wheel torque for agile starting to safe continuous output at higher speeds. An electric actuator engages second gear at around 140 km/h at the latest, which corresponds to the electric motor’s maximum speed of around 13,500 rpm.
With the increase in performance due to the additional electric motor, the development team was also able to improve the efficiency of the entire vehicle in parallel – and achieve lower emissions as well as lower consumption.
Inspired by Formula 1™, developed in Affalterbach: the AMG high-performance battery
The development of the lithium-ion energy storage system is inspired by technologies proven in the Mercedes-AMG Petronas F1 Team’s Formula 1™ hybrid racing cars. During the development, the experts from the Formula 1™ engine shop High Performance Powertrains (HPP) in Brixworth exchanged ideas intensively with Mercedes-AMG in Affalterbach. The AMG high-performance battery combines high power that can be called up frequently in succession with low weight to increase the overall performance of the vehicle. Added to this are the fast energy draw and the high-power density. This means that during a brisk drive-in hilly terrain, for example, drivers can immediately call on the full power potential on uphill stretches, while recuperation is strong when driving downhill.
80 kW continuous output and 150 kW peak output
The high-performance battery in the GLC 63 S E PERFORMANCE offers a capacity of 6.1 kWh, 80 kW continuous power and 150 kW peak power for ten seconds. Charging takes place via recuperation or the installed 3.7 kW on-board charger with alternating current at a charging station, wall box or household socket. The battery is designed for fast power delivery and draw, not for the longest possible range. Nevertheless, the electric range of 12 kilometres allows a practical activity radius, for example for quiet and all-electric driving from the residential area to the outskirts of the city or to the motorway.
Operating strategy: electric power always available
The basic operating strategy is derived from the hybrid powerpack of the Mercedes-AMG Petronas Formula 1 racing car. As in the top class of motorsport, maximum propulsion is always available when the driver calls it up by kick-down – to accelerate powerfully out of corners or to overtake quickly. The electric power can always be called on and frequently reproduced via high recuperation performance and needs-based recharging.
Performance Hybrid Drive can control the traction of one wheel
The control of vehicle dynamics also benefits from the hybrid drive. Instead of braking intervention by ESP®, the electric motor can also control traction as soon as a wheel signals too much slip. To achieve this, the intelligent control system reduces the drive torque of the electric motor, which is transmitted to the wheel via the limited-slip rear differential. The result is that ESP® does not have to intervene at all, or only later. Advantage: The combustion engine can thus be operated at a higher torque. This improves agility afterwards and increases efficiency. In addition, the power otherwise “destroyed” during braking can be used to charge the battery.
AMG SPEEDSHIFT MCT 9G transmission with wet start-off clutch
The power is transmitted in both Mercedes-AMG GLC models via the AMG SPEEDSHIFT MCT 9G transmission (MCT = Multi-Clutch Transmission), in which a wet start-off clutch replaces the torque converter. It reduces weight and, thanks to its lower inertia, optimises response to accelerator pedal input, especially during spurts and load changes. The elaborately calibrated software ensures extremely short shift times as well as fast multiple downshifts if required. In addition, the double-declutching function in the “Sport” and “Sport+” drive programs delivers a particularly expressive shifting experience. There is also the RACE START function, which ensures optimal acceleration from a standstill. The ECO start/stop function is automatically activated in the “Comfort” drive program; the “Glide” function can be activated in “Individual” mode.
In the GLC 43, the AMG Performance 4MATIC all-wheel drive features a permanent power distribution between the front and rear axles of 31 to 69 percent. The rear-biased configuration provides for enhanced dynamic handling, including higher lateral acceleration and improved traction when accelerating. In the GLC 63 S, the AMG Performance 4MATIC+ fully variable all-wheel drive transmits the drive power to the road. The engine torque can be allocated continuously and as required from 50/50 between the front and rear axles up to 100 percent to the rear.
AMG DYNAMICS a standard component of the AMG DYNAMIC SELECT drive program selection
The AMG DYNAMIC SELECT drive programs (five for the GLC 43, eight for the GLC 63 S) enable a wide range of vehicle characteristics from comfortable to dynamic. The distinct driving modes offer an individual driving experience, precisely tailored to different driving conditions.
The integrated “AMG DYNAMICS” driving dynamics control system is added as part of the AMG DYNAMIC SELECT drive programs. This enhances the stabilising functions of the Electronic Stability Program ESP® with interventions to add agility to the steering characteristics and additional ESP® functions. When cornering at speed, for example, brief braking intervention at the inner rear wheel generates a defined yawing moment around the vertical axis for responsive and precise turn-in.
The extent and efficiency of these interventions depend on the AMG DYNAMIC SELECT program selected, whereby the driver can determine the set-up in “Individual” model. The ESP® can be adjusted in three stages. “On” is the standard selection that offers high safety, adapted to the sporty character of the overall vehicle. “Sport”, on the other hand, allows higher drift angles, while “Off” allows the system to be switched off completely for a particularly sporty driving style on closed-off racetracks.
AMG RIDE CONTROL suspension with Adaptive Damping System
Both models are equipped with the AMG RIDE CONTROL steel spring suspension with Adaptive Damping System. It combines sporty driving dynamics with high long-distance comfort. The basis for this is provided by the front axle, with specially developed steering knuckles and suspension joints on the spring control arm, and by the rear axle, which also features elasto-kinematics designed for driving dynamics. Complementing this, the Adaptive Damping System continuously adapts the damping at each individual wheel to the current demand – always taking into account the preselected suspension level, the driving style and the condition of the road surface. In addition to an improvement in ride quality and comfort, this leads, above all, to an increase in driving safety. There is a choice of three different damping maps (“Comfort”, “Sport” and “Sport+”).
AMG sports braking system and AMG exhaust system with sporty engine sound
The AMG sports brake system in the GLC 43 guarantees outstanding deceleration values and optimum control. Internally ventilated and perforated brake discs measuring 370 x 36 millimetres with 4-piston fixed callipers are fitted to the front axle and 360 x 26 millimetres with 1-piston floating callipers to the rear.
In keeping with the extreme power values and the associated performance, the AMG high-performance composite brake system with 6-piston fixed callipers at the front (internally ventilated and perforated brake discs 390 x 36 mm) and 1-piston floating callipers at the rear (internally ventilated and perforated brake discs 370 x 26 mm) comes as standard on the GLC 63 S. The brake system impresses with very short braking distances as well as maximum stability and fade-resistance under heavy use. In addition, it scores with a long service life and a particularly fast response.
