quattro® HAS MAINTAINED ITS GRIP ON OUR THINKING AND THE ROADS WE TRAVEL.

For more than 30 years, Audi has been

focused on quattro® all-wheel drive.

During that time, it has evolved into

an overarching idea of performance, a

technological system of ratios, power

delivery and driving dynamics work-

ing seamlessly together, orchestrated

through the drivetrain, providing power

where and when it is needed most. In

many ways, this has been a three-decade drive, from the Alps to the autobahn—

and points beyond. You’ve seen quattro® capabilities in the way we dominated

the World Rally Championship for years, in the grip you have in inclement weath-

er, and in the variable power distribution you enjoy in good conditions.

For more

than 30 years, and with over ﬁve million quattro® systems on the road, we have

continued to reﬁne the technology, developing an available rear sport dieren-

tial to help maximize performance and available torque vectoring to assist with

cornering traction while helping to improve handling. We’ve boldly stuck to what

worked while the world was trying to catch up, and we built on it.

Torque is distributed to

all four wheels in vary-

ing amounts_

Impressive stability, more assured

road-holding, enhanced agility and

improved steering precision_

quattro® directs the amount

of torque required to suit the

job at hand_

Torque vectoring_

By independently braking the inside corner-

ing wheels, torque is then transferred to

the outside cornering wheels. This intelli-

gent application of power, known as torque

vectoring, is available on select quattro®

models and helps promote neutral handling

by calculating the driver’s steering input

and desired level of acceleration.

Sport dierential_

To help ensure high cornering agility, the

available sport dierential uses torque

vectoring, and then adds to that by me-

chanically applying additional torque to the

outside rear cornering wheel. Through an

electrohydraulic multiplate clutch pack and

gear-set, the outside rear cornering wheel

speed is increased by as much as 10%.

When we think of

a good idea, it sticks.

1 When driving during cold, rainy, snowy or icy weather conditions, ensure that your vehicle is equipped with appropriate all-season or winter tires. Even with appropriate tires, you must always

drive in a manner appropriate for the weather, visibility and road conditions.
