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.
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.
Today, in that same competitive spirit, quattro® all-wheel drive continues to be refined. In Audi vehicles with a longitudinal engine configuration, quattro® is essentially a mechanical system with a self-locking center differential and continuously variable torque distribution. quattro® instantly responds to wheel speed differences and dynamically adjusts power to the wheels with the best traction. It is supported by advanced electronic control systems that together offer numerous benefits over other all-wheel drive systems. Featuring a 40:60 rear torque bias, the latest version of quattro® offers sports car-like performance and handling with uncompromised all-wheel drive traction.
power of quattro® is its ability to inspire driver confidence, giving
you traction when you need it, where you need it, regardless of road
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.
