Audi A7 gets automatic emergency braking system to prevent rear-end collisions

Article by Christian Andrei, on July 14, 2011

To prevent rear-end collisions, the Audi A7 has been fitted by Robert Bosch GmbH with an automatic emergency braking system that made its debut on the A8. The system detects objects in front by using a video camera and radar.

Bosch system's sensor data analyzes and determines whether braking has to be applied and if so, in what amounts. When a collision is possible, the brakes are prepared for use and a warning alarm will sound.

If the warning is not heeded, maximum braking occurs about half a second prior to the impact. The electronic stability control of Bosch will then help bring the vehicle to an orderly stop. The A7 is Audi’s second liftback model. This vehicle competes against the Jaguar XF and the Mercedes-Benz CLS.

It comes with a selection of four V-6 engines, which would be two gasoline and two diesel. These four engines all possess brake regeneration and stop-start systems.

Also, depending on the engine, clients may choose between two transmissions -- a sporty seven-speed all-wheel drive or a multitronic front-wheel drive.

The A7 shares much of its innovative features with the A8. The company manufactures the A7 at its Neckarsulm facility in Germany. Prices begin at 48,900 euros in the German brand's home market.

The new five-door Audi A7 Sportback should allow the German premium carmaker to target a new market segment with its sporty charm, emotional design and advanced technology. After all, the Audi A7 Sportback should appeal to those seeking the comfort of a sedan, the sportiness of a coupe and the practicality of a station wagon. Featuring a lightweight body laden with aluminum components, the new Audi A7 Sportback has dimensions of 4.97 meters (16.31 ft) in length, 1.91 meters (6.27 ft) in width and 1.42 meters (4.66 ft) in height.

This new five-door owes its dynamic presence to its long hood, long wheelbase, short front overhang and flowing C-pillars, as well as its sharply dropping rear. This new offering from Audi comes standard with Bi-xenon headlights and LED tail lights, but could be fitted with the optional LED headlights that provide all light functions with while minimizing energy consumption. The headlights feature all-weather light function, thereby getting rid of the classic fog lights. The new Audi A7 Sportback could be powered with any of the available four powerful and efficient V6 engines. For instance, the 3.0 TDI engine mated to a multitronic transmission could develop up to 150 kW (204 hp) of output while emitting only 139 grams of carbon dioxide per kilometer (223.70 g/mile).

Complementing the dynamics and efficiency of these engines is a sporty chassis that is equally blessed with an array of efficient technologies like electromechanical power steering. This chassis also contributes a lot to the comfort of passengers, especially when they are on a long trip. Outstanding vibrational comfort is made possible by implementing systematic hydraulic damping in the axle and drivetrain bearings and tuning all related components.

Audi also employed an extremely stiff yet very lightweight body mostly made of aluminum and high-tech steels. Passenger comfort is also helped by the fact that the Audi A7 Sportback features a very low interior noise level even when moving at highway speeds, with the V6 engine providing impressive audio feedback.

Customers should welcome the practicality offered by the Audi A7 Sportback with its 535-liter (18.89 cu ft) luggage compartment that is very accessible through its large rear hatch. This capacity could be expanded to a max of 1,390 liters (49.09 cu ft) when the rear seat backrests are folded down.

On the other hand, the interior of the new Audi A7 Sportback reveals a sporty yet welcoming cabin that features the so-called "wrap-around," a horizontal line that seemingly hugs the front occupants as well as the wave-shaped application strip on the dashboard. Moreover, the new A7 Sportback comes with advanced MMI operating system that has been made more intuitive and logical, thanks to the fewer number of buttons and the addition of the central menu button.

This system may be availed with the new optional head-up display that shows the most relevant information on the windshield. Additionally, the MMI touch system is a welcome fusion of a hard drive navigation system and touchpad technology. This touchpad can be used to execute several functions. For instance, a driver could just use a finger to write the phone number or letters of the destination on the touchpad. Customers may avail of optional features like climate-control and massage functions for the front leather seats and the available ambient lighting. Audi will commence sales of the new Audi A7 Sportback this fall at a starting price of €51,600.
