Audi expands its RS model line-up with the RS 7 Sportback, making its debut at the Detroit motor show.
The large coupe uses a twin-turbo four-litre V8 that produces 412kW/700Nm and enables it to sprint from 0 – 100kph in just 3.9 seconds.
The standard 250kph speed limit is in place, although the governor can be deactivated at the customer’s request. In those instances, where the dynamic package plus option is taken, top speed is a hair-raising 305kph. Top speed with the optional dynamic package is a mere 280 km/h.
Despite those rather intimidating performance figures, Audi still feels the need to mention fuel consumption, stating this Sportback uses an average of 9.8 litres/100km.
As expected, this RS is packed with a number of top tech tools. Chief among these, according to Audi, is its cylinder on demand system that, at low to medium loads and engine speeds, deactivates four of the eight cylinders by closing their valves via electromechanical actuators.
The V8 then operates as a four-cylinder, thereby increasing its efficiency, at least until the driver accelerates strongly again. It is estimated that savings of up to 10 per cent can be achieved when driving at moderate speeds with the COD system in operation.
Audi’s eight-speed tiptronic is standard on the sporty RS 7 and allows drivers to choose between D and S models or change gears via the shift paddles or the selector lever.
Quattro permanent all-wheel drive is standard to distribute power between the front and rear axles. In standard configuration, however, there’s a 60/40 split with bias to the rear axle. Audi also offers an optional sport differential for the rear axle that uses two superposition gears to distribute power between the wheels.
As for its appearance, the RS 7 is fitted with polished 20-inch forged lightweight wheels in a seven twin-spoke design with the option of 21-inch cast wheels in three designs.
Internally vented discs with black painted six-pot calipers are standard. Red calipers and carbon fibre ceramic brake discs with grey calipers can also be optioned.
The RS 7 is equipped with air suspension that lowers the body by 20mm, while adaptive damping adjusts the suspension’s response based on road conditions, the driver’s style and the Audi drive select mode in use.
The RS 7 Sportback will be available in South Africa by the end of 2013.
