Audi has launched the mighty RS 7 Sportback in South Africa, but don't let its beautiful looks fool you of the beast that lies within.The RS 7 Sportback is a large five-door coupe from Audi powered by a twin-turbo 4.0-litre TFSI V8 unit pushing out 412kW between 5 700 and 6 700rpm, along with 700Nm available between 1 750 and 5 500rpm.Audi says the high-revving four-litre engine has been rigorously designed for low load-change and flow losses, hence it develops power quickly and spontaneously. The two twin-scroll turbochargers, are located with the intercooler in the inside V of the cylinder banks. Switchable flaps in the exhaust system make the engine sound even louder at the push of a button or during heavy acceleration. And if that still isn’t enough, there’s also an optional sport exhaust system.Image gallery: Audi RS 7 SportbackThe car jolts from zero to 100km/h in 3.9 seconds, with a top speed limited at 250km/h and 305km/h when fitted with the Dynamic Package Plus. Average fuel consumption is rated at 9.8 litres/ 100km. The automaker says its most innovative efficiency technology in the RS 7 Sportback is the cylinder on demand (COD) system: "This works with low to medium loads and engine speeds, it deactivates cylinders 2, 3, 5 and 8 by closing their valves via electromechanical actuators. The engine then runs as a four-cylinder unit until the driver puts more foot to the throttle."The standard eight-speed tiptronic is specially tuned to the sporty nature of the RS 7 Sportback. Drivers can choose between D and S modes or change gears themselves using the shift paddles on the steering wheel or the selector lever.The Audi RS 7 Sportback comes standard with quattro permanent all-wheel drive along with a centre differential with a high lock rate and separate oil cooler to regulate its temperature. Audi adds that the torque vectoring supports the work of the differential at the cornering limit with minimal braking of the wheels that are under a reduced load. There’s also an optional sport differential for the rear axle, which uses two superposition gears to actively distribute the power between the wheels. It comes with adaptive air suspension which lowers the car by 20mm, making the car sporty, yet still comfortable. The body includes up to 20% aluminium and includes many high-strength and ultra high-strength steels. Some specific design details give the car a sporty edge such as distinctive bumpers and a high-gloss black protective grille with honeycomb structure at the front of the car as well as add-on parts in matt aluminium, says Audi. At the rear there’s an extended spoiler, diffuser and the two large, elliptical tailpipes while the car sits on 21” forged aluminium wheels in a five-spoke blade design and 19” braking system. There’s also a dual-branch RS exhaust system and LED light clusters.INTERIOR TO MATCHInside the car the dial instruments have black faces, white scales and red needles along with a 3D RS 7 logo in the tachometer. RS badges are shown off on the flat-bottomed, three-spoke leather steering wheel, illuminated door entry sills and the displays for the MMI and driver information system. Carbon inlays are standard, with the headlining in black cloth. Other standard goodies include RS sport seats with integrated head restraints and RS 7 logos; the black Alcantara and leather seats can be alternatively be covered in honeycomb-quilted Valcona leather in either black or lunar silver. Boot space ranges from 535 to 1 390 litres depending on the position of the rear seat backs.The Audi RS 7 Sportback is priced at R 1 450 500 including all taxes and the standard five-year or 100 000km Audi Freeway Plan.
