Dynamism, agility and performance – these three attributes characterise the standard all-wheel drive of the new AMG GLA 35 4MATIC. The variable AMG Performance 4MATIC combines the best possible traction with plenty of driving enjoyment. The torque distribution is infinitely variable to suit the dynamic handling requirements. The spectrum ranges from front-wheel drive only to a 50:50 percent distribution to the front and rear axles. A multi-disc clutch integrated into the rear axle differential is responsible for variable torque distribution between the front and rear axles. It is controlled electro-mechanically. The influencing factors for torque distribution are not only the driving speed, the lateral and longitudinal acceleration and the steering angle, but also the difference in rotational speed between the individual wheels, the gear selection and the accelerator position.
The main advantages of electro-mechanical control over an electro-hydraulic system relate to more refined driving dynamics – primarily due to the significantly faster response and speed-independent actuation of the discs over the entire adjustment range.
As long as ESP® is activated, the 4MATIC system stays in “Comfort” mode. As soon as the driver presses the “ESP® SPORT Handling” or “ESP® OFF” button, the 4MATIC system switches to “Sport” mode – for even more agile handling and even higher stability limits.
