Audi option packages make it easy for you to customize your S4 exactly to your liking.
Audi quattro® with Sport DifferentialDifferentialWhen a vehicle turns a corner, the inside wheels cover a shorter distance than those on the outside. Differential
Audi quattro®quattro®Audi quattro® permanent all-wheel drive, has had over a 30-year-long tradition.quattro® all-wheel drive is part of a tradition of innovation that has lasted for more than 25 years. The original idea was simple: transfer power from front to back as needed. After all, a wheel spinning is wasted motion. Along with better performance, quattro® provides high levels of active safetyActive SafetyActive safety refers to everything designed to help prevent an accident from happening. Active Safety . and improved traction on virtually all surfaces.
The Sport Differential works to better distribute power and compensate for differences in wheel rotation when cornering. You can feel the difference at every turn.
Audi Parking SystemAudi Parking SystemThe Audi Parking System (APS) makes parking easier. Audi Parking System Advanced

Using ultrasonic sensors to measure distance, Audi parking system emits an intermittent warning tone to indicate how far the car is from an obstacle. As the distance decreases, the warning tone becomes faster. It first sounds when the car is a little over 5 feet from the obstacle, becoming continuous when only 20 centimetres away. Rear Audi parking system switches on automatically when the vehicle is in reverse.
The Audi Navigation Package
The Audi Navigation Package features a 7" full-colour LCD screen and MMI® control logic. This latest generation of MMI® is powered by a 40-GB hard drive, plus benefit from a colour driver information system and 3D topography graphics that include the buildings in many cities. Additional advantages include convenient voice control of navigation, telephone and entertainment.
Adaptive Cruise ControlAdaptive Cruise ControlAdaptive cruise control builds on the functionalities of the cruise control system and, within certain system limits, maintains the driver-selected comfort spacing from the vehicle in front automatically.Adaptive Cruise Control
The system uses a special radar sensor to measure the distance to the vehicle ahead. If the distance is too small, the system reduces speed moderately by easing the throttle or automatically applying the brakesBrakesA vehicle's brakes must be matched to its power, weight, and top speed. Brakes . Once the road ahead is clear again, adaptive cruise controlCruise ControlThis electronic aid keeps the car moving at a constant speed, reducing stress on the driver particularly where speed limits must be observed, when towing a trailer, and on long trips.Cruise Control accelerates the car up to the previously set speed.
7-speed S-tronic Transmission with Self-locking Crown-gear Centre Differential
The state-of-the-art dual-clutch automatic transmission allows the driver to make lightning fast gear changes, while the four-wheel drive system features the next evolutionary stage of quattro®. Only available with S-tronic, the new self-locking centre differential and electronically controlled torqueTorqueTorque is what causes rotational speed to change. Just as greater net forces cause greater linear accelerations, greater torques cause greater rotational or angular accelerations.Torque vectoring makes driving through bends now even more precise and dynamic.
