2019 Mercedes GLC 63 AMG 4Matic+ SUV – Performance And Sophistication. 2019 Mercedes AMG GLC63 4Matic+ – Drive, Interior and Exterior. Subscribe.
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.
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.
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.
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.
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.
