AMG Performance 4MATIC+ variable all-wheel drive

After the E-Class from Mercedes-AMG, the GLC also received the AMG Performance 4MATIC+ all-wheel drive. This intelligent system combines 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 handling stability and a high level of safety under all conditions, in the dry, in the wet or in snow. The transition from rear-wheel to all-wheel drive and vice versa is seamless, because the 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 split 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 driving modes

The four AMG DYNAMIC SELECT drive programs "Comfort", "Sport", "Sport+" 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 driving modes, the driver has the option of pressing the "M" button to switch directly to manual mode, in which gear shifts are executed exclusively using the paddle shifters on the steering wheel. If required, the suspension settings can be specially selected as well.

"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 gear shifts 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 disengages 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+" drive programs are designed for high driving dynamics. This results from an agile accelerator pedal characteristic with direct set-up and emotively appealing gear shifts with shorter shift times and double-clutching function on downshifts. The increased idle speed in "Sport+" 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.
