Permanent all-wheel drive quattro® power is distributed as needed to all four wheels providing high levels of active safety, and dependable traction on most driving surfaces as well as excellent road holding, even in cross-winds.

Nearly 30 years ago, the notion of a car with permanent four wheel drive was revolutionary. Audi called it quattro® and its benefits would set a new benchmark for driver confidence and performance.

The simple, yet profound result of sending power to all wheels means that snow covered mountain passes, rain-slicked highways and gravel-strewn rural roads are no longer encountered with apprehension. While on smooth dry roads, quattro® offers a level of performance unachievable by two-wheel drive cars.

The advantage of all-wheel drive was most apparent when Audi introduced quattro® to the World Rally Championship. quattro® seemed to defy physics with startling acceleration and remarkable traction. The result was an astounding 24 wins and a number of World Championships. If that wasn't enough of an endorsement for quattro®, it was later deemed an "unfair advantage" and banned from road racing altogether after repeatedly dominating the field.

The power of quattro® is its ability to inspire driver confidence, giving you traction when you need it, where you need it, regardless of road conditions.

Additionally, Audi vehicles with a transverse engine configuration, such as the A3 and TT, feature the HALDEX version of quattro®. HALDEX is a hydraulic system with an electronically controlled multi-plate clutch. Utilizing an advanced control module that monitors road speed, cornering and traction, quattro® can anticipate wheel slip and quickly respond to any driving situation. This version of quattro® provides superlative traction at all times by dynamically sending power to the wheels with the most grip.
