Audi has finally revealed the Audi RS7, which has been in the rumormill for over two years now with reports ranging from its proposed powerplant options to its exterior design. The most recent was the spyshots of the RS7 without camouflage in a metropolitan area Brazil.
Well, Audi is set to jump in and compete with the recently unveiled BMW M6 Gran Coupe. The RS7 will be powered by a 4.0 TFSI engine producing 560hp. The sprint from naught to 100km/h happens in just 3.9 seconds while the speed governor can be deactivated upon customer request to permit a top speed of up to 305 km/h.
The powerhouse avails the 560hp between 5,700 and 6,700rpm and a constant 700Nm of torque are available between 1,750 and 5,500rpm. The powerplant is mated to a standard eight-speed tiptronic transmission matched with the latest evolution of the Audi’s quattro four-wheel drive system, offering the choice between D (drive), S (sport) and M (manual) modes.
Audi explains that the high-revving four-liter engine has been rigorously designed for low load change and flow losses and hence it develops this power quickly and spontaneously. The cylinder heads have the exhaust side on the inside and the intake side on the outside. The two twin-scroll turbochargers, which produce up to 1.2 bars of relative boost pressure, are located together with the intercooler in the inside V of the cylinder banks.
This is then complemented by the fact that the gas paths are very short and response very good. The RS-specific engine management and unthrottled intake system also contribute to the dynamic character of the twin-turbo V8. Switchable flaps in the exhaust system make the engine sound even fuller at the push of a button or under strong acceleration. A more aggressive sport exhaust system will also be offered.
Of course, the most innovative efficiency technology in the new Audi RS7 Sportback is the cylinder on demand (COD) system where at low to medium loads and engine speeds, it deactivates cylinders 2, 3, 5 and 8 by closing their valves via electromechanical actuators. This will ensure that the 4.0 TFSI runs as a four-cylinder engine until the driver accelerates more strongly again. The operating points in the active cylinders are displaced toward higher loads, increasing efficiency.
The adaptive air suspension is set to harmonize perfectly with the dynamic character of a sport coupe by lowering the body by 20 millimeters. 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.
Also part of the suspension is 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. The other option is the dynamic steering with its steplessly variable steering boost and ratio.
The exterior will feature a choice of ten exterior colors, including the new shade Nardo gray and the exclusive finish Daytona gray, matt effect. The two styling packages are matt aluminum and carbon where the front center air inlet also sports a quattro badge. With the carbon styling package, the front splitter and the diffuser are somewhat more boldly shaped.
The interior features dial instruments in black faces, white scales and red needles. A 3D RS7 logo in the tachometer is a further accent. It has a flat-bottomed, three-spoke leather steering wheel, illuminated door entry sills and the displays for the MMI and driver information system also sport RS badges. The driver information system includes a shift light, which indicates when the rev limit is reached. Other details include the displays for boost pressure and oil temperature.
The interior is further enhanced by the RS sport seats with pronounced side bolsters, integrated head restraints and RS7 logos are standard. They are covered in a combination of black Alcantara and leather, and the center sections feature diamond quilting. The seats can also be covered alternatively in high-grade, honeycomb-quilted Valcona leather in either black or lunar silver.
