The concept of the super-fast Avant is more tightly woven into the Audi DNA than virtually any other hallmark of Vorsprung durch Technik, and that concept has been refined yet again in the creation of the new, fourth generation RS 6 Avant.
Bristling with the technological accomplishments already delivered by the new A6 Avant, the latest addition to the Audi Sport fold combines formidable twin-turbo eight-cylinder TFSI power with state-of-the-art efficiency features including mild hybrid drive and cylinder-on-demand technology, helping to deliver epic performance as responsibly as possible.
With the exception of the front doors, roof and tailgate, the exterior of the RS 6 Avant comprises exclusively RS-specific parts, and to look at the car at rest on its sizeable 21-inch wheels shrouded by broad flared arches that expand its width by 40mm on each side, this is immediately evident.
The new RS 6 Avant is one of the first Audi Sport models to feature the new RS design language. In addition to a new bonnet with powerdome, it also adopts the front headlights from the A7 model line which are not only slimmer and more sporting in style but also offer the RS Matrix LED laser headlight with darkened trims as an additional USP of the RS 6 Avant in the A6 family. Similar to the LED rear lights, they feature a dynamic indicator along with RS-specific sequencing when the vehicle is locked and unlocked.
The three-dimensional honeycomb structure within the Singleframe grille is finished in gloss black, and its surround and the quattro logo in the bumper have been removed in this latest incarnation of the design. Below the standard LED headlights, side air inlets open on the strikingly drawn new RS bumper and extend almost into the lower edge of the headlights. The designers have taken their cue for this application from the front-end of the Audi R8 supercar.
The characteristic Avant silhouette dominates in the side view – elongated front section, long, straight roofline and flat D pillars, which rest on the quattro blisters. RS-specific sills with black inserts also add emphasis to the flanks. The dynamic rear-end consists of the roof edge spoiler and an RS-specific bumper with rear diffuser and design elements in gloss black. In hallmark RS style, the RS exhaust system flows on both sides into oval chrome-coloured tailpipes.
The 4.0 TFSI in the new Audi RS 6 Avant delivers 600PS and 800 Nm (590.0 lb-ft) of torque, which is maintained at this high level between 2,050 and 4,500 rpm. In just 3.6 seconds the high-performance Avant sprints from zero to 62mph, and where conditions permit the driver can see 124mph by the time 12 seconds have elapsed. Top speed is electronically governed at 155mph.
Thanks to the 48-volt main electrical system the twin-turbo V8 combines maximum performance with high efficiency. A belt alternator starter lies at the heart of the mild hybrid system (MHEV). Up to 12 kW of power can be recovered during light deceleration and stored in a separate lithium-ion battery. If the driver lifts off the accelerator at a speed of between 34 and 99mph, the drive management selects one of two options: Depending on the driving situation and setting in the standard Audi drive select dynamic driving system the new RS 6 Avant recovers energy or coasts for up to 40 seconds with the engine switched off. Re-applying pressure on the accelerator instructs the belt alternator starter to restart the engine. MHEV technology allows for start/stop operation at speeds of up to 13mph. Fuel savings of up to 0.8 litres per 100 kilometres are possible in everyday driving.
Another key efficiency-focused component is the cylinder on demand (COD) system, which at low to intermediate loads and speeds deactivates cylinders 2, 3, 5 and 8 in the high gears by switching off injection and ignition and closing the intake and exhaust valves. In four-cylinder operation the operating points in the active cylinders are displaced toward higher loads in areas of the characteristic map with higher efficiency, while the deactivated cylinders largely run without losses, like gas springs. When the driver presses the accelerator pedal, they are reactivated instantly.
For all its efficiency the 4.0 TFSI remains a thoroughbred V8 in terms of character and sound. The driver can influence that sound using the Audi drive select system. In the new, customisable RS1 and RS2 modes accessible via Audi drive select, customers decide themselves whether the sound should be full-blooded or balanced.
The standard eight-speed tiptronic with optimised shift times and a new Launch Control function transmits the power of the 4.0 TFSI to the quattro permanent all-wheel drive. The drive forces are distributed to the front and rear axle in a ratio of 40:60 via the all-mechanical centre differential. If one wheel slips, more drive torque automatically goes to the axle with the better traction. Up to 70 percent can be channelled to the front wheels and up to 85 percent to the rear wheels.
The wheel-selective torque control optimises the agile and safe handling of the new RS 6 Avant – it brakes the wheels with reduced load on the inside of a bend slightly before they can begin to spin. The quattro sport differential shifts the drive torque when cornering at speed as required between the rear wheels, thus improving traction, stability and dynamics.
The pioneering interior design accentuates the character of the new RS 6 Avant with its driver orientation and inlays in matt brushed dark aluminium. With its horizontal alignment and its tiered, three-dimensional structure, the instrument panel appears light and sleek. The user interface of the all-digital operating system harmonises with the clear black-panel design. The top MMI touch response display is incorporated almost invisibly into the black-panel architecture. The “RS Monitor” display provides the driver with the option to see an overview of the temperature status of the drive components, the maximum g acceleration figures along with information on tire pressure and temperature in the top display.
In the Audi virtual cockpit, special RS displays provide information on tyre pressure, torque, power output, engine oil temperature, boost pressure, lap times, acceleration measurements and g forces. The shift light display prompts the driver to upshift when the maximum engine speed is reached.
The fully perforated and flat-bottomed sport leather steering wheel features new large RS shift paddles made of aluminium and multifunction buttons that allow the driver to also directly select the new Audi drive select RS1 and RS2 modes. RS and RS 6 logos adorn the interior on the steering wheel, seats and the illuminated front door sill trims. The Audi Sport emblem is projected onto the road when the front or rear doors are opened.
The RS sport seats come in perforated Valcona leather with honeycomb pattern and RS embossing. Their perforation also allows ventilation for the first time.
The new RS 6 Avant is even roomier inside. The luggage compartment has a capacity of between 565 and 1,680 litres, and the loading width between the wheel arches is now 1.05 metres, 14 millimetres larger than the previous model. The split-folding rear seat bench in the ratio 40:20:40 can be released and folded conveniently from the luggage compartment – the luggage compartment length has grown to 1.99 metres as a result. A power tailgate and luggage compartment cover are standard. In combination with the optional convenience key, sensor control allows the tailgate to be opened with a foot gesture. The optional swivelling trailer towing hitch features an electric release function. Also available as an option is the camera-based trailer assist, which helps the driver when reversing and manoeuvring with a trailer.
The paint range for the new Audi RS 6 Avant includes thirteen colours, including the two RS-specific colours Nardo grey and Sebring black, crystal effect along with a choice of five matt effect paint finishes. The Audi exclusive range offers numerous customisation options.
