2011 Audi A7 Sportback

The Audi A7 Sportback is pure high-tech. Its body is very lightweight thanks to numerous aluminum components. The elegant interior shows a craftsman's level of workmanship. The four V6 engines combine refined power with groundbreaking efficiency. The 3.0 TDI with 150 kW (204 hp) and multitronic has CO2

emissions of just 139 grams per kilometer (223.70 g/mile). The sporty chassis comes with new solutions, such as electromechanical power steering. When it comes to assistance and infotainment systems, the luxury-class coupe exhibits all of the innovative power expected of Audi

Audi offers a wide range of the latest-generation driver assistance systems. They are tightly networked with one another and other systems in the vehicle, making them extremely capable and versatile. The respective control units are connected via the fast and modern FlexRay bus system, allowing the driver assistance and chassis systems to be precisely controlled.

The heart of the driver assistance systems is the new adaptive cruise control with stop & go function (ACC). It uses the data from four radar sensors, a video camera and the ultrasonic sensors, incorporates navigation data and analyzes a multitude of additional signals, from the activity of the turn signals to the steering angle to trailer detection. Its functions range from automatic stop & go in rush-hour traffic to the electronic monitoring of high-speed highway driving at speeds of up to 250 km/h (155.34 mph).

The driver uses the MMI system to determine how the vehicle should behave in ACC mode. The choices are "dynamic" - powerful acceleration when the roads are clear, spontaneous and direct when following traffic; "standard" - balanced in all situations; or relaxed and fuel-efficient cruising in "comfort" mode Another high-end system is Audi side assist, which from speeds of 30 km/h (18.64 mph) upwards warns the driver of

critical situations when changing lanes. It uses radar to monitor the space behind the Audi A7 Sportback. The speed limit display detects important traffic signs and their supplemental signs with a camera and shows them in the instrument cluster display or in the optional head-up display. The night vision assistant uses a thermal

 imaging camera and highlights persons that it detects in front of the vehicle. It projects its black-and-white images onto the instrument cluster display. If it detects a potentially hazardous situation, it marks the person red and optionally displays a warning symbol in the head-up display.

The Audi pre sense safety system is available in a number of different versions in the Audi A7 Sportback. It uses the highly networked systems on board and initiates preventive measures in the event of an imminent collision. In the version Audi pre sense basic, the system reacts when it detects an instable driving situation

. The front seatbelts are electrically tensioned; the sunroof and the side windows are closed, leaving just a small gap; and the traffic behind is warned
