The new Audi RS 6 Avant stands for pioneering performance. It is lighter and more efficient than the predecessor version and its performance has improved once more. The RS 6 Avant accelerates from 0 to 100 km/h (62.14 mph) in just 3.9 seconds. If the customer wishes, its top speed can be 305 km/h (189.52 mph). Its 4.0 TFSI develops 412 kW (560 hp) while averaging just 9.8 liters of fuel per 100 kilometers (24.00 US mpg). The new Audi RS 6 Avant is a high-performance sports car for everyday use and leisure. Its character and thoroughly sporty design is the work of quattro GmbH, a wholly owned subsidiary of AUDI AG. RS models boast powerful engines and constitute the dynamic spearhead of the Audi portfolio. The abbreviation “RS” represents many things: the most powerful engine within a model line, quattro permanent all-wheel drive, extremely dynamic performance, an understated look and comprehensive everyday practicality.
Pioneering and strong – the new Audi RS 6 Avant
The new Audi RS 6 Avant unites 412 kW (560 hp) of power and 700 Nm (516.29 lb-ft) of torque with unrestricted practicality for everyday use and leisure. Developed and built by quattro GmbH, a wholly owned subsidiary of AUDI AG, this high-performance Avant offers superior performance and groundbreaking efficiency. Its twin-turbo V8 averages 9.8 liters of fuel per 100 km (24.00 US mpg) over a combined cycle. Aluminum and high-end steels in the body have reduced the vehicle’s weight.
The new Audi RS 6 Avant is self-assured and powerful. From a displacement of 3,993 cc, the direct-fuel-injection twin-turbo V8 delivers 412 kW (560 hp) and a constant 700 Nm (516.29 lb-ft) of torque between 1,750 and 5,500 rpm. Positioned in the cylinder banks’ 90-degree V, two twin-scroll turbochargers ensure that considerable torque is generated quickly. This large Avant accelerates from 0 to 100 km/h (62.14 mph) in just 3.9 seconds. On request, Audi will increase the car’s top speed from 250 km/h (155.34 mph) to 280 km/h (173.98 mph) or even 305 km/h (189.52 mph). Average fuel consumption is 9.8 liters per 100 kilometers (24.00 US mpg) – 30 percent less than the previous model.
The cylinder on demand (COD) system, which temporarily switches off four cylinders during part-load operation, is a deciding factor in this efficiency. Active engine mounts apply targeted counterpulses to attenuate the minor vibrations that occur during these phases. COD technology reduces standard fuel consumption by around five percent; driving at moderate speeds can achieve up to twelve percent.
Thanks to a sportily tuned eight-speed tiptronic with a tall eighth gear, the power of the 4.0 TFSI is transferred to the quattro permanent all-wheel drive, which makes use of a refined center differential. Torque vectoring, an intelligent software solution, aids the quattro drivetrain. If desired, Audi will supplement quattro with a sport differential to actively distribute power between the rear wheels.
Standard equipment for this new high-performance Avant also includes RS adaptive air suspension. This firmly tuned suspension with controlled damping lowers the vehicle body by 20 millimeters (0.79 in). It is managed by the Audi drive select dynamics system, as are the sport differential and dynamic steering, which adjusts the steering ratio to the vehicle’s speed. The driver can switch between several modes of operation. Audi offers a taut RS Sport suspension plus with Dynamic Ride Control (DRC) as an alternative to the RS adaptive air suspension.
The new Audi RS 6 Avant boasts 20-inch forged wheels fitted with 275/35 R 20 tires as standard. 21-inch wheels with 285/30 R 21 tires are also available. Six-piston brake calipers encircle the front brake discs in a wave design and measure 390 millimeters (15.35 in) in diameter. Audi offers optional 420-millimeter (16.54 in) carbon-fiber ceramic discs for the front axle. Electronic Stabilization Control (ESC) features a sport mode that can be completely deactivated.
Lightweight and stable: The body
The body of the new Audi RS 6 Avant consists of high-tech steels and approximately 20 percent aluminum. Thanks to Audi’s lightweight excellence, this new top-of-the-line model weighs nearly 100 kilograms (220.46 lb) less than its predecessor. The body nevertheless excels with respect to crash safety and torsional rigidity.
The exterior of this high-performance Avant includes matt aluminum applications, a high-gloss black protective grille, the bumpers, extensions on the sills and wheel arches. An RS roof spoiler, a diffuser and the RS exhaust system’s two tailpipes make it clear that the RS 6 Avant is the sporty high-end vehicle of this model line. An optional RS Sport exhaust system is available with black tailpipe trims and a more distinctive sound profile. Two optional styling packages – matt aluminum or carbon – further customize the appearance. Xenon plus headlights with LED daytime running lights and LED rear lights are standard. LED headlights with shaded trim are optional.
The interior of the new Audi RS 6 Avant is dominated by sporty black. The instrument dials are white and the needles red. The RS-specific three-spoke leather sport steering wheel is flat-bottomed and has an especially thick, well-contoured rim. Trim elements in aluminum look or Piano finish, illuminated door sill trims with RS 6 badges and decorative carbon inlays accentuate the look. RS sport seats with pronounced side bolsters and integrated head restraints are standard. The seats are covered in a combination of black Alcantara and leather. The center sections featuring diamond quilting are a highlight. The RS 6 Avant comes standard with two pronounced rear bucket seats featuring integrated head restraints which are matched to the look of the front seats. A three-person rear bench seat is also available.
Standard equipment in the new Audi RS 6 Avant also includes four-zone automatic air conditioning, MMI navigation plus with MMI touch and the ten-speaker Audi sound system. High-end options range from a head-up display through a Bang & Olufsen advanced sound system through to driver-assistance systems. Other options include adaptive cruise control with Stop&Go function and the night vision assistant, which highlights detected pedestrians. Audi connect including car phone, complements the MMI navigation plus by delivering online services to the car. Passengers can surf the web via a Wi-Fi hotspot.
Customer deliveries of the Audi RS 6 Avant will begin in Germany in the second half of 2013. The basic price will be 107,900 euros.

Engine
The Audi RS 6 Avant 4.0 TFSI handsomely illustrates Audi downsizing strategy. The V8 biturbo draws impressive power from its 3,993 cc of displacement in every driving situation. Its peak output of 412 kW (560 hp) occurs between 5,700 and 6,600 rpm, with a constant 700 Nm (516.29 lb-ft) of torque available from 1,750 to 5,500 rpm.
Every detail is an expression of the high-end character of the charged eight-cylinder engine. The aluminum-silicon crankcase is manufactured in a low-pressure permanent mold casting, which ensures a high level of material uniformity. The bedplate – a stable frame for the crankshaft bearing bridges – further enhances the block’s rigidity. The chain drive is located on the back to save space. The engine’s compact construction reduces its length to 497 mm (19.57 in); bore and stroke measure 84.5 and 89.0 mm (3.33 and 3.50 in), respectively. Even with all key add-on parts, this engine weighs just 224 kilograms (493.84 lb).
An unthrottled intake system supplies the four-liter V8, which has a specific engine management system, with air; the Audi FSI direct injection meters the fuel. Switchable flaps in the intake ports mix the incoming air in a cylindrical motion to enhance charging and combustion. The directly injected and intensively swirled fuel cools the combustion chambers. This method enables the high compression ratio of 10.1:1.
Two turbochargers generate up to 1.2 bar of relative boost pressure. The twin-scroll technology, in which the exhaust gas of every two cylinders flows to the turbine wheel via separate exhaust ports, avoids undesirable interactions between the gas columns. The end effect is an early and steep torque buildup.
The large turbochargers and their air-to-water heat exchanger are located in the inside V of the cylinder banks rather than in the usual location outside next to the crankcase. This layout enables short gas flow paths with minimal flow losses and spontaneous engine response. Elaborate and effective insulation of hot components ensures thermally stable conditions in the inside V.
Sound flaps in the dual exhaust system make the engine’s sound profile even more resonant. They are controlled independently from engine load, engine speed, the mode in the Audi drive select dynamics system and the eight-speed tiptronic operating level. An optional RS sport exhaust system is available from quattro GmbH.
Extensive package: technologies from the modular efficiency platform
The 4.0 TFSI has many technologies from Audi modular efficiency platform – including the start-stop-system. Innovative thermal management controls coolant flow through the engine while it is warming up so that the engine oil heats as quickly as possible. A regulated oil pump varies oil pressure in two stages. At the Audi plant in Győr, Hungary, high-end technologies such as the panel honing of cylinder barrels are used during assembly of the V8 engine. The piston pins have a fine, diamond-like carbon (DLC) coating.
Another pioneering innovation is the cylinder on demand (COD) technology that is based on the Audi valvelift system (AVS). It reduces standard fuel consumption by around five percent; driving at moderate speeds can achieve up to twelve percent.
At low to moderate load and engine speed – up to around 250 Nm (184.39 lb ft) and 3,500 rpm – the COD technology deactivates cylinders 2, 3, 5 and 8 by closing the valves and stopping fuel injection and ignition to them. Efficiency in the active cylinders increases because the operating points are displaced toward higher loads. Immediately before closing, the combustion chambers are once again filled with fresh air – this solution ensures relatively low internal pressures in the cylinders.
The switchover occurs within hundredths of a second via sleeves that move axially on the camshafts; they are moved by pins that are electromagnetically extended into spiral-shaped slots on the outside of the sleeves. This transition process runs so smoothly that the driver practically only notices the four-cylinder operation by the message in the instrument cluster display. The cylinders are reactivated as soon as the driver presses the accelerator pedal more firmly.
While the V8 is temporarily running as a V4, ignition only takes place at every 180 degrees of crankshaft angle. Its crankshaft drive produces higher rotational oscillations – the active engine mounts counteract this effect. Utilizing electromagnetic oscillation coil actuators, they induce phase-offset counter oscillations which largely cancel engine vibration. The active engine mounts are also operational during idling.
