Audi quattro four-wheel drive system now has its own technical title for each four-wheel drive version.

From the perspective of quattro S 1, we can see that Audi's quattro four-wheel drive system has a certain history. Nowadays, the quattro system appears in various Audi production cars, which means that the technology is mature and extra points.
Most quattro systems today are not what they used to be. Most models are designed with electronically controlled multi-disc clutches, which have been modified for the sake of manufacturing cost and emission. Because too many urban SUVs use electronically controlled four-wheel drive, it seems that this "gecko" is no longer so pure.

It can adjust the distribution of front force and rear axle force more reliably than any electronic control technology.
Crown gear differential When the wheel idles or leaves the ground, the driving force on the idling side of the wheel is transmitted to the wheel that can bear the force, and the crown gear differential will transmit up to 85% of the torque to the rear axle. When the adhesion of the rear axle wheel decreases, it will also transmit up to 70% of the torque to the front axle. Foreign Audi four-wheel drive TOP 10 ranking, you can watch the following video.

Audi Q5L Matching quattro ultra Four-wheel Drive System Now quattro systems don't all use Torsten central differential, just like Q5L uses Torsten central differential, but now Q5L is replaced by quattro ultra Four-wheel Drive System, which uses multi-disc clutch differential to transmit power by pressing friction plates.
Audi quattro has a special logo. We should understand quattro as a trademark of brand technology, not a specific form. The Tolson differential is not unique to Audi.
