On an Audi vehicle, the term indicates a specific type of all-wheel drive (AWD) system. This drivetrain technology distributes engine power to all four wheels, offering enhanced traction and control compared to front-wheel or rear-wheel drive systems. An example is an Audi A4 labeled with the term, signifying that it utilizes this AWD system.
The system’s importance lies in its ability to improve handling and stability, especially in challenging driving conditions such as snow, ice, or rain. Its benefits include increased grip, reduced wheel spin, and enhanced cornering performance. Developed in the late 1970s and first introduced on the Audi Quattro rally car, it has become synonymous with performance and reliability in AWD technology.
