What Does Audi Quattro Mean? (And Why It Changed Driving)

The Origin of the Audi quattro

Used by Audi since 1980, the term “quattro” refers to Audi’s all-wheel drive system fitted to both road and performance models. Audi typically writes the system in lowercase (quattro), while the iconic original Group B rally car from the 1980s is written with a capital “Quattro”.

The Audi Quattro was a true revolution in motorsport. At a time when most competitors were using two-wheel drive, Audi introduced all-wheel drive to rallying and dominated the World Rally Championship, winning multiple titles. This success led Audi to introduce quattro technology across its road car range.

Today, quattro is most commonly associated with Audi’s performance models, including RS models such as the RS3, TT RS, and the R8 supercar.

How does the quattro system work?

Most all-wheel drive systems use a component called a transfer box, which sits after the gearbox and splits engine power between the front and rear axles. However, traditional systems can be heavy and take up significant space, making them less suitable for smaller vehicles.

Audi’s solution is a centre differential, which uses a set of gears to distribute engine torque between the front and rear wheels. This system can automatically adjust where power is sent, directing torque to the axle with the most grip.

Because it is more compact and efficient than a traditional transfer box, Audi’s system improves both performance and drivability. It is especially effective in slippery conditions, but also enhances stability and traction in everyday driving.
