The Audi V8 was the first Audi to combine quattro all-wheel drive with an automatic transmission.
The Audi V8, produced from 1988, was Audi’s first production car with a V8 engine and its flagship luxury sedan. It paired permanent quattro four-wheel drive with a four-speed ZF 4HP24A automatic transmission, an important distinction from earlier Audi quattro applications that were generally associated with manual gearboxes.
The car was based on an enlarged version of the Audi 100 and 200 bodyshell, but it received a distinct luxury design, larger engines and upgraded drivetrain technology. Early cars used a 3.6-litre V8; later versions received a 4.2-litre engine.
This fact is often confused with the Audi A8 because the A8 replaced the V8 in 1994 and continued Audi’s luxury, quattro-equipped tradition. However, the pioneering combination in this question belongs specifically to the Audi V8.
