Four driven wheels are a part
of what drives our progress.
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
®
oers 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.
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 dierential and continuously
variable torque distribution. quattro
®
instantly responds to wheel speed dierences and dynamically adjusts power to the
wheels with the best traction. It is supported by advanced electronic control systems that together oer numerous benefits
over other all-wheel drive systems. Featuring a 40:60 rear torque bias, the latest version of quattro
®
oers sportscar-like
performance and handling with uncompromised all-wheel drive traction.
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.
