quattro generation IV

[citation needed]

Starting from 1996 on Audi A4 / S4 / RS4 (B5 platform), Audi A6 / S6 / allroad / RS6, Audi A8 / S8 with both manual and automatic transmissions. Also on VW Passat B5, where it was initially referred to as syncro, but by the time it reached US soil, it had been re-christened 4motion. Also used on the Volkswagen Phaeton and Volkswagen Group D platform sister vehicles; also the Volkswagen Touareg where they use separate transmissions, PTUs and front axles.

The manually locking rear differential from the earlier generations was replaced with a conventional open differential, with "Electronic Differential Lock" (EDL) (which detects wheelspin via ABS road wheel speed sensors, and applies brakes to the one spinning wheel, thus transferring torque via open differential to the opposite wheel which has more traction). EDL works at speeds up to 80 km/h (50 mph) on all quattro models (on non-quattro models: up to 40 km/h (25 mph).

System type: Permanent four-wheel drive.

Torsen T-2 centre differential, 50:50 'default' split, automatically apportioning up to 67% of torque transfer to either front or rear axle.

Open rear differential, Electronic Differential Lock (EDL).[4]

Open front differential, Electronic Differential Lock (EDL).[4]
