The Magic of Audi's Quattro Technology

12 May, 2009 : The term Quattro means four in Italian language. It is used by Audi for four-wheel drive systems that come on Audi vehicles. Presently, all Audi models feature the Quattro all-wheel drive setup.
Audi’s quattro technology was first introduced in 1980 at the Geneva Motor Show in Switzerland. Since then the word quattro is been used for all Audi 4WD vehicles. After the introduction of the Quattro technology, it posted many motor-sport victories. Drivers such as Michele Mouton, Stig Blomqvist, Hannu Mikkola and Walter Rohrl brought the Audi quattro four world championship titles in 1980s. Soon, cars with permanent all-wheel drive started making a mark in racing circuit, including an overall win in the 1988 American TransAm series. In 1996, the A4 quattro Super Touring competition car received the winner's title in all seven national touring car championships that it entered.
The quattro technology not only established itself in motor sports, but in cars that are used on roads daily. Along with better performance, quattro provides high levels of safety, dynamism and improved traction on all kinds of surfaces. On cars with longitudinally installed engines, a differential sends power and makes up for differences in wheel rotation when cornering. If the car has a transverse engine, a Haldex clutch performs these tasks.
Since 1980, over 1,800,000 cars with permanent all-wheel driveline have been developed. In 1982, Audi introduced five all-wheel-drive variants - the Audi Coupe, the Audi 80/90 and the Audi 100/200. The Audi 100/200, like its predecessor, was also available as an Avant. Conceived as a front-wheel-drive car, all these models could be easily converted to permanent all-wheel drive without much effort and expense. They reflected Audi's fundamental policy to offer a quattro variant in every model line. In the light of Audi's motorsport successes, they all were well-received by car buffs. In 2004 alone, Audi came up with 209,469 quattro vehicles.
For 1987 model year, another vital new feature was added to the quattro concept - the Torsen differential, a self-locking worm, and gear unit that replaced the manual differential lock. This device redistributes engine torque steplessly as required for traction, so that in extreme situations the axle with the better traction receives up to 75 percent of the available torque. The Torsen differential develops its locking action only under load and the vehicle's anti-lock braking system can take effect when needed. Today, advanced technologies such as electronically controlled differential locks in the axles and the ESP stabilisation program match the action of the Torsen differential.
