Self Study Program 962103 – Audi quattro
VAG SSP 962103. Over 20 years ago, Audi brought all-wheel drive to the sports car market with the Audi quattro. The Audi quattro did not use a transfer case like the other all-wheel or four-wheel drive vehicles of its time. Instead, a central differential was added to the 016 5-speed manual transmission. This design was much lighter than a transfer case.
Three separate differentials were used in the Audi quattro so that each wheel could turn at its own speed when cornering. This reduced power loss and tire life by minimizing “tire scrub.”
The all-wheel drive system offered the same advantages back then as it does today:
- Traction on slippery surfaces
- High speed stability
- Traction on steep hills
- Excellent stability under load change conditions
