4Matic (stylized as 4MATIC) is the marketing name of an all-wheel drive system developed by Mercedes-Benz. It is designed to increase traction in slippery conditions. With the introduction of the 2017 E 63 S sedan, Mercedes-AMG announced a performance-oriented variant of the system called AMG Performance 4MATIC+.
The 4MATIC system includes the 4-wheel Electronic Traction System (4-ETS). That means individual sensors and breaks on every wheel. So when only one of your wheels has traction, the 4MATIC system can keep you rolling. Furthermore, the wheels can spin at different speeds.18 sept 2018

Turbos offer better fuel efficiency than conventional engines with the same power output, and they also produce less emissions.3 sept 2019
