Audi RS6 Avant is a super wagon with insane power
Audi RS6 Avant has 600PS and 800Nm
The concept of the super-fast Avant is moretightly woven into the Audi DNA than virtually any other hallmark of Vorsprungdurch Technik, and that concept has been refined yet again in the creation ofthe new, fourth generation Audi RS6 Avant.
The 4.0 TFSI in the new Audi RS6 Avant delivers 600PS and 800 Nm 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 ata speed of between 34 and 99mph, the drive management selects one of twooptions: Depending on the driving situation and setting in the standard Audidrive select dynamic driving system the new Audi RS6 Avant recovers energy orcoasts for up to 40 seconds with the engine switched off.
Re-applying pressure on the acceleratorinstructs the belt alternator starter to restart the engine. MHEV technologyallows for start/stop operation at speeds of up to 13mph. Fuel savings of up to0.8 litres per 100 kilometres are possible in everyday driving.
Another key efficiency-focused component isthe cylinder on demand (COD) system, which at low to intermediate loads andspeeds deactivates cylinders 2, 3, 5 and 8 in the high gears by switching offinjection and ignition and closing the intake and exhaust valves.
In four-cylinder operation the operatingpoints in the active cylinders are displaced toward higher loads in areas ofthe characteristic map with higher efficiency, while the deactivated cylinderslargely run without losses, like gas springs. When the driver presses theaccelerator 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 withoptimised shift times and a new Launch Control function transmits the power ofthe 4.0 TFSI to the quattro permanent all-wheel drive. The drive forces aredistributed to the front and rear axle in a ratio of 40:60 via theall-mechanical centre differential. If one wheel slips, more drive torqueautomatically goes to the axle with the better traction. Up to 70 percent canbe channelled to the front wheels and up to 85 percent to the rear wheels.
The wheel-selective torque controloptimises the agile and safe handling of the new RS6 Avant – it brakes thewheels with reduced load on the inside of a bend slightly before they can beginto spin. The quattro sport differential shifts the drive torque when corneringat speed as required between the rear wheels, thus improving traction,stability and dynamics.
In the new Audi RS6 Avant the front andrear axles use a five-link design to handle the induced longitudinal andtransverse forces separately. The linkages and the subframes are made largelyof aluminium. The track width is 1,668 millimetres at the front and 1,651millimetres at the rear.
The body of the new RS6 Avant is 20millimetres lower than in the Audi A6 Avant with standard suspension; at speedsof 74mph and above, it is lowered by another 10 millimetres. At the other endof the scale, a lift mode is available to raise the vehicle by 20 millimetresfor low speed driving. The very wide spread of the RS sport air suspensionoffers the driver a free choice between long-distance comfort and maximumperformance.
The new Audi RS6 Avant features progressivesteering with its direct ratio as standard. The system develops significantlyhigher return forces with increasing steering angle for precise steeringfeedback. Its newly developed power assistance directly connects the driver androad.
The driver can change the character of theRS6 Avant using the Audi drive select dynamic handling system. Six profiles areavailable: comfort, auto, dynamic, efficiency, and the individuallyconfigurable RS-specific RS1 and RS2 modes, which can also be activated directlyusing the “RS MODE” steering wheel button. This automatically opensthe RS-specific displays in the Audi virtual cockpit.
The Audi drive select dynamic handlingsystem influences the engine and transmission management, the power steering,the suspension, the dynamic all-wheel steering, the quattro sport differential,the engine sound and the characteristics of the automatic air conditioning. TheRS2 mode exists specifically to influence the Electronic Stabilisation Control(ESC) directly at the push of a button.
The new RS6 Avant is fitted standard with21-inch cast aluminium wheels in 10-spoke star design, which are shod with275/35 size tyres. An RS-specific wheel in 22-inch 5-V-spoke trapezoid designwith 285/30 tires will be available on the Vorsprung specification. The newlydeveloped RS ceramic brake system weighs around 34 kilograms less than itssteel counterpart, thus reducing unsprung masses. The Electronic StabilisationControl (ESC) features a sport mode or can be switched off entirely.
The pioneering interior design accentuatesthe character of the new Audi RS6 Avant with its driver orientation and inlaysin matt brushed dark aluminium. With its horizontal alignment and its tiered,three-dimensional structure, the instrument panel appears light and sleek. Theuser interface of the all-digital operating system harmonises with the clearblack-panel design. The top MMI touch response display is incorporated almostinvisibly into the black-panel architecture. The “RS Monitor” displayprovides the driver with the option to see an overview of the temperaturestatus of the drive components, the maximum g acceleration figures along withinformation on tire pressure and temperature in the top display.
In the Audi virtual cockpit, special RSdisplays provide information on tyre pressure, torque, power output, engine oiltemperature, boost pressure, lap times, acceleration measurements and g forces.The shift light display prompts the driver to upshift when the maximum enginespeed is reached.
The fully perforated and flat-bottomedsport leather steering wheel features new large RS shift paddles made ofaluminium and multifunction buttons that allow the driver to also directlyselect the new Audi drive select RS1 and RS2 modes. RS and RS6 logos adorn theinterior on the steering wheel, seats and the illuminated front door silltrims. The Audi Sport emblem is projected onto the road when the front or reardoors are opened.
The RS sport seats come in perforatedValcona leather with honeycomb pattern and RS embossing. Their perforation alsoallows ventilation for the first time.
The new Audi RS6 Avant is even roomierinside. 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, 14millimetres larger than the previous model. The split-folding rear seat benchin the ratio 40:20:40 can be released and folded conveniently from the luggagecompartment – the luggage compartment length has grown to 1.99 metres as aresult.
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.
