Kuato is the transliteration of English Quattro, which is the registered trademark of Audi's four-wheel drive technology under Volkswagen.

Quattro has always been the focus of Audi's publicity, and its performance is superior. It is worth noting that the key technologies of the four-wheel drive system cannot be completely and absolutely expressed only by Quattro and 4motion, because Audi, which belongs to Volkswagen, enjoys the same brand technology as Volkswagen, so the key technologies of the four-wheel drive systems of two different brands may be the same on some models.

the origin of the four-wheel drive system

the history of the four-wheel drive system can be traced back to 1977. At that time, Volkswagen made a four-wheel drive named lltis for the German military. With the four-wheel drive system, this model performed very well on various roads, which also made Piech, then Audi technical manager, have the idea of introducing the four-wheel drive system into cars.

Audi's quattro technology was unveiled in 198, and the first model equipped with quattro system was also named quattro. The first generation quattro system adopted the structure of open central differential (manual locking)+front axle open differential+rear axle open differential (manual locking).

the first generation quattro four-wheel drive system is equipped with a differential at the rear end of the gearbox, which is driven by a hollow transmission shaft, and the power is transmitted to the front axle differential through the hollow shaft, and then a transmission shaft is installed at the rear end of the central differential to transmit the power of the engine to the rear axle differential. In this way, the transfer box with large volume and heavy weight is omitted, thus effectively solving the space problem.
