2014 Audi RS7 Sportback revealed at Detroit Auto Show.

2014 Audi RS7 Sportback
Audi has just added the RS 7 Sportback to its lineup. The large five-door coupe was revealed at the 2013 Detroit Auto Show.

The Audi RS 7 uses a 4.0 TFSI engine producing 560 bhp and 516 lb-ft of torque.The sprint from 0-62 mph takes just 3.9 seconds, and the speed governor can be deactivated upon customer request to permit higher top speeds. Top speed with the optional dynamic package is 172 mph and 190 mph with the dynamic package plus. The Audi RS 7 Sportback consumes on average just 24 mpg.

The most innovative efficiency technology in the new Audi RS 7 Sportback is the cylinder on demand (COD) system. At low to medium loads and engine speeds, it deactivates cylinders 2, 3, 5 and 8 by closing their valves via electromechanical actuators. The 4.0 TFSI then runs as a four-cylinder engine until the driver accelerates more strongly again.

The standard eight-speed tiptronic is specially tuned to the sporty character of the Audi RS 7 Sportback. Drivers can choose between the modes D and S or change gears themselves using the shift paddles on the steering wheel or the selector lever, which sports a unique RS design. While the lower gears of the tiptronic are closely spaced for sporty response, eighth gear is tall like an overdrive to reduce fuel consumption.

The Audi RS 7 Sportback comes standard with quattro permanent all-wheel drive for its decisive advantage in traction and driving safety compared with its two-wheel-drive competitors. At the heart of the quattro system is a center differential with a high locking rate and a separate oil cooler to regulate its temperature. It distributes the power as needed within a wide range between the front and rear axles. In the standard configuration, 60 percent flows to the rear and 40 percent to the front.

The Audi RS 7 Sportback comes standard with polished, 20-inch forged lightweight wheels in a seven twin-spoke design. The five-door high-performance coupe also rolls on optional 21-inch cast wheels in a choice of three designs.
Powerful brakes are located behind the large wheels. The four internally vented discs feature a weight-saving wave design and measure 390 millimeters (15.35 in) in diameter up front. Pins decouple the steel friction rings from the aluminum brake caps. Black painted six-piston calipers – optionally available in red – grip the discs. Audi also offers optional 420 millimeter (16.54 in) carbon fiber ceramic discs with anthracite gray calipers. The electronic stabilization control (ESC) has a Sport mode and can also be deactivated entirely.

Equipped with the air suspension, which harmonizes perfectly with the dynamic character of a sport coupe, the new RS 7 Sportback is sporty, yet still comfortable. The RS 7 adaptive air suspension lowers the body by 0.79 inches. Adaptive damping, another of the system’s features, adjusts the suspension’s response to the condition of the road, the driver’s style and the mode selected in the Audi drive select system, with which the driver can alter the function of key components in multiple steps.

Audi offers the taut sport suspension plus with dynamic ride control (DRC) as an alternative to the air suspension. It uses steel springs and three-stage adjustable dampers that are connected to one another via diagonal oil lines and a central valve. Another option, which can also be integrated into Audi drive select, is the dynamic steering with its steplessly variable steering boost and ratio. As with the standard electromechanical steering, its characteristics are specially tailored for the RS 7 Sportback.

The body of the Audi RS 7 Sportback includes up to 20 percent aluminum and includes many parts of high-strength and ultra high-strength steels.

The Audi RS 7 Sportback comes with a few driver assistance systems. One of these is the adaptive cruise control with stop & go function including Audi pre sense front. This keeps the car at the proper distance from the vehicle ahead and in many situations can help to avoid accidents or mitigate their consequences. Audi active lane assist helps the driver to keep the RS 7 Sportback on course. The park assist handles the steering when parking. The night vision assistant with highlighting of detected persons reduces the stress of driving in the dark. Audi side assist and the speed limit display are other features.
