The RS7 is equipped with twin turbo eight-cylinder petrol engine that produces a respectable 560 hp and 516 lb-ft torque with an eight-speed tiptronic automatic transmission. The RS7's twin-turbo V8 gains an extra 37 hp to 595 hp and 36 lb-ft of extra torque on over-boost, enough to send it from 0-100 kmh in just 3.7 seconds. This acceleration is 0.2 seconds faster than the regular RS models they're based on, and is faster than several supercars. Audi claims RS Performance cars can reach 200 kmh in just 12.1 seconds. Top speed is 305 kmh for the sleek RS7. Fuel consumption remains unchanged at 9.48 litres/100 kms travelled. Engine The new RS performance model is equipped with the most powerful version of the free-revving V8 bi-turbo power unit with a displacement of 3,993 cc. Power output has been increased by 37 hp (597 hp), which is available between 6,100 and 6,800 rpm. The maximum rpm has thus also been increased by 200 revs. A constant 516.3 lb-ft of torque is available between 1,750 and 6,000 rpm. On top of this the engine has an over-boost function allowing the driver to temporarily draw on up to 553.2 lb-ft between 2,500 and 5,500 rpm. Overboost is activated automatically under full load if the engine/transmission setting is set to “dynamic” mode. The boost pressure indicator in the RS menu turns red when over-boost is active. Audi uses a cylinder on demand (COD) system so at low to moderate load and engine speed, this de-activates cylinders two, three, five and eight by closing their valves and shutting off fuel injection. The high-performance power unit then runs as a four-cylinder engine until the driver presses firmly down on the gas pedal again. The only thing the driver notices is significantly reduced fuel consumption. Drivetrain The standard eight-speed tiptronic has been designed for maximum sportiness in the new RS 7 Sportback performance. All gear changes are superfast and flexible. The driver can choose between the modes D and S or change gears manually either by tapping the selector lever or by using the shift paddles on the RS multifunction sport leather steering wheel. In manual mode, a shift indicator in the driver information system (DIS) or optional head-up display indicates the rev limit. While the lower gears of the tiptronic are closely spaced for sporty response, eighth gear is tall to reduce fuel consumption. “Quattro” permanent all-wheel drive delivers the power to the road and distributes torque as needed via the center differential. In the standard configuration, 40 percent flows to the front axle and 60 percent to the rear axle. The wheel-selective torque control intervenes as necessary. On request, Audi will combine quattro all-wheel drive with the optional sport differential on the rear axle: It uses two superposition gears to steplessly vary the distribution of the power at the rear axle between the wheels. In fast curves, it literally pushes the RS performance model into the radius. The new RS performance model come standard with 21-inch cast aluminum wheels. Wheels with a 5-double-arm design are reserved exclusively for the RS 7 Sportback performance. These are also in matt titanium look with a gloss turned finish. Both wheels are optionally available in silver or gloss anthracite black, gloss turned finish. The four internally ventilated brake rotors have a weight-saving wave design, shaving nearly three 6.6 lb compared with a brake system with conventional rotors. The front rotors measure 15.4 in diameter and are gripped by six-piston calipers. Audi also offers optional carbon fibre-ceramic brake discs, which all together reduce weight by an additional 22 lb. Electronic Stabilization Control (ESC) has a Sport mode that can be de-activated altogether if need be. Interior and Equipment The RS 7 Sportback performance come standard with RS sport seats with pronounced side bolsters and integrated head restraints. Audi offers the seats in the colour combination black and blue with the optional RS performance design package. This includes new seat upholstery in an Alcantara/leather combination with a honeycomb pattern and matching contrasting stitching on the armrests, control elements and floor mats. Rounding out this interior combination are knee pads in Alcantara and Carbon twill blue inlays. This sophisticated and exclusive carbon material is interwoven with a blue thread. The RS performance model feature a generous list of standard equipment, which includes four-zone automatic air conditioning, MMI navigation plus with touchpad control (MMI touch) and the Audi sound system. Optional high-end features range from a head-up display and the Bang & Olufsen Advanced Sound System to the driver assistance systems, including adaptive cruise control with Stop&Go function and the night vision assistant.
