All driver assistance and safety systems of the A4 model series are available in the new A4 allroad quattro*.Playing a central role here is adaptive cruise control (ACC) Stop&Go including traffic jam assist. It relieves drivers in slow-moving traffic up to a driving speed of 65 km/h (40.4 mph) not only by assuming the tasks of braking and accelerating but also by steering on well-built roads. The predictive efficiency assistant, unique in this class, helps to save fuel in conjunction with MMI navigation or MMI navigation plus by giving relevant tips while driving. It evaluates GPS information in the immediate vicinity of the car. On highways it can improve fuel economy by up to ten percent in this way.
Moreover, Audi also offers an entire array of innovations that improve safety. Park assist uses twelve ultrasonic sensors to assist in parallel and perpendicular parking, so that the driver only has to operate the accelerator, shift gears and brake. Rear cross traffic assist helps in backing out of parking spaces with poor visibility and warns of approaching traffic – visually, acoustically and by a brake jolt.
Exit warning is activated as soon as the new Audi A4 allroad quattro comes to a stop. If other vehicles are then approaching from the rear, the system warns all occupants by lighting LED light conductors in the interior side trim if they begin to open the doors. Collision avoidance assist intervenes if the car has to drive around an obstacle to avoid an accident. Based on data from the front camera, ACC and radar sensors, it computes a recommended driving line within fractions of a second. Its first action is a warning jolt to alert the driver to the danger. As soon as the driver steers, the system assists in executing the necessary lane change with targeted steering torque interventions in the power steering system.
Turn assist performs monitoring of oncoming traffic when turning left over a driving speed range from two to ten km/h (1.2 - 6.2 mph). In a dangerous situation, it brakes the car to a stop. The system is active in the background as soon as the driver activates the turn signal to turn across the road.
The solution Audi pre sense city, which is standard, monitors for other vehicles and pedestrians up to a driving speed of 85 km/h (52.8 mph); in an emergency it can apply full braking power. The lineup is rounded out by other assistance systems such as camera-based traffic sign recognition, Audi active lane assist and Audi side assist.
If the new A4 allroad quattro is used as a tow vehicle, the optional trailer maneuver assist steers the car-trailer combination backwards in the direction the driver indicates with the rotary/push-button control of the MMI. It also manages turning the steering wheel in the opposite direction and stabilizes the trailer when driving straight ahead.
