Quattro is a permanent all wheel drive system used on Audi brand automobiles. Quattro was first introduced in 1980 on the Audi Quattro Coupé based on the Audi 80 and has since been deployed to most of the models that Audi sells. Four wheel drive or 4x4, is a type of four wheeled vehicle drivetrain configuration that enables all four wheels to receive power from the engine simultaneously in order to provide maximum traction. ...

Audi 80 The Audi 80 was an automobile from Audi produced between 1972 and 1995 and initially shared its platform with the Volkswagen Passat. ...

In the original Quattro system, where the engine and transmission are situated in a longitudinal position, power is sent from the transmission to a mechanical center Torsen differential which splits it between the front and rear axles. Under ideal conditions power is split 50/50 front to rear. The 50/50 split helps prevent wheel slip from starting, which is better than systems that can only react after wheel slip starts. In extreme cases, up to 67% of the engine's power can be directed to a single axle. The power split between left and right wheels has progressed through open, lockable and eventually limited slip differentials with electronic control. An engine is something that produces some effect from a given input. ... Transmission is the following: Generally, transmission is the act of passing something on. ... The term, longitudinal means front-to-back or top-to-bottom as opposed to transverse which means side-to-side. In automotive engineering, the term, longitudinal refers to an engine in which the crankshaft is oriented along the long axis of the vehicle, front to back. ... Transmission is the following: Generally, transmission is the act of passing something on. ... Torsen, a contraction of torque-sensing, was invented by an American company called Gleason Corporation. ... In this differential, input torque is applied to the ring gear (blue). ...

In some recent Audi models using a transverse engine and transmission positioning, power is sent primarily to the front axle, however an electrohydraulic center Haldex limited slip coupler may divert up to 100% of the power to the rear axle as conditions warrant. This action causes a sudden jolt which may break traction on the wheels that still have it. The power split between left and right wheels is achieved through limited slip differentials with electronic control. This system is also available in most Volkswagen vehicles under the name 4motion.
