Quattro® All-wheel Drive.

Permanent all-wheel drive systems are not created equal. And they certainly don’t perform that way, either. quattro is essentially a mechanical system devised around a torque-sensing, self-locking, center differential that shifts torque instantaneously to where it’s needed. This means quattro is adjusting power between front and rear axles more than 100 times a second, helping ensure torque is delivered to the wheels where traction exists. Under normal driving situations, quattro distributes the power between each axle by sending 40 percent to the front wheels and 60 percent to the rear wheels, enhancing the driving dynamics while helping maintain optimum control. Constantly assessing grip, quattro ensures the best possible combination of traction and handling, regardless of the road conditions.

FSI® Direct Injection.
Audi Fuel Stratified Injection, or FSI®, offers the benefits of increased performance and fuel efficiency. FSI direct injection delivers a precise amount of fuel directly into the engine cylinders as opposed to the engine intake runners. This advanced process helps ensure a more complete combustion, thereby diminishing waste and increasing power.

Additionally, the specially designed piston heads compress the fuel-air mixture in a spiraling motion, creating the most efficient combustion possible. Making the most of these technologies allows for greater efficiency in the combustion process.
