The new Audi A6 allroad has arrived at Audi dealerships, combining the familiar strengths of the allroad formula with more sophisticated all-wheel-drive technology and an expanded electrified powertrain lineup. Prices start at €77,250 for the six-cylinder diesel, while the new plug-in hybrid version starts at €80,250.

Designed to bridge the gap between a premium estate and a more capable all-weather vehicle, the Audi A6 allroad continues to focus on long-distance comfort, confident handling and traction across changing road conditions. At the heart of the latest model is Audi’s quattro ultra all-wheel-drive system, which is designed to deliver the traction benefits of quattro while reducing drivetrain losses when four-wheel drive is not required.
Audi A6 allroad gets a new plug-in hybrid option
The latest Audi A6 allroad is available with a 3.0-liter V6 TDI featuring MHEV plus technology and an electrically powered compressor. For the first time, however, customers can also choose a plug-in hybrid powertrain.
That addition broadens the A6 allroad’s appeal by combining electrification with the model’s established focus on long-distance versatility. Both the V6 TDI and plug-in hybrid versions use quattro ultra technology, giving the A6 allroad the ability to optimize power distribution according to the conditions.
The result is a drivetrain designed to balance efficiency with the instant availability of all-wheel-drive traction.
How Audi quattro ultra works
Unlike a conventional permanent all-wheel-drive system that continuously drives both axles, quattro ultra can temporarily disconnect the rear drivetrain when additional traction is not required.
The system uses an electronically controlled multi-plate clutch at the transmission output together with a second decoupling clutch integrated into the rear axle differential. When the vehicle is cruising under low load and there is little risk of wheel slip, both clutches can open.
This disconnects the driveshaft and rear drivetrain components, reducing mechanical friction and helping improve efficiency.
But the important point is that the Audi A6 allroad does not simply wait for the wheels to lose traction before engaging the rear axle. quattro ultra works predictively, constantly analyzing the vehicle’s behavior and the road ahead to determine when all-wheel drive will be advantageous.
Predictive all-wheel drive can react before wheel slip occurs
Audi’s quattro ultra system continuously evaluates a wide range of parameters, including steering angle, accelerator demand, transmission setting, lateral and longitudinal acceleration, body movements and the estimated coefficient of friction between the tires and road.

It also learns from the driver’s behavior and takes the selected Audi drive select mode into account.
The system can predict approximately 0.5 seconds in advance when all-wheel drive is likely to be required. Once a decision is made to engage the rear axle, the complete process takes around 200 milliseconds.
That means quattro can be ready before the driver actually needs the additional traction.
This approach is particularly useful when pulling away, accelerating hard, entering a corner at speed or encountering a low-grip surface such as wet asphalt, snow or loose gravel.
“The transition between different operating modes of the all-wheel-drive system is imperceptible to the driver. What the driver feels in any situation is the traction and driving dynamics associated with quattro,” said Rouven Mohr, Member of the Board of Management for Technical Development at AUDI AG.
Front-wheel drive when efficiency matters, quattro when traction is needed
During efficient driving conditions, the quattro ultra system can send 100 percent of available drive torque to the front axle. If conditions change, the electronically controlled multi-plate clutch progressively brings the rear axle into operation.
Torque distribution is continuously adjusted according to traction, driving dynamics and comfort.

Under heavy acceleration, Audi says more than 70 percent of available torque can be transferred to the rear wheels on dry roads. This allows the A6 allroad to retain the characteristic traction and dynamic behavior associated with quattro while still benefiting from reduced mechanical losses during less demanding driving.
The result is a system that attempts to provide the best of both worlds: front-wheel-drive efficiency when additional traction is unnecessary and all-wheel-drive capability when it matters.
Four decades of Audi quattro technology
The latest A6 allroad is also the newest chapter in a technology story that began with the original Audi quattro in 1980.
Over more than four decades, Audi has progressively developed its all-wheel-drive systems. The technology has evolved from the manually locking center differential of the original Ur-quattro to various generations of Torsen differentials and, ultimately, today’s electronically controlled systems.
Audi has now produced more than 15.6 million vehicles equipped with quattro. According to the company, that represents approximately one-third of all Audi vehicles produced since the introduction of the technology.
Few technologies are as closely associated with a premium automotive brand as quattro is with Audi, and the A6 allroad remains one of the clearest expressions of that philosophy.
A6 allroad combines comfort with all-weather capability
The Audi A6 allroad has traditionally occupied a distinctive position in the market. Rather than being a conventional luxury estate or a full-size SUV, it combines estate-car driving characteristics with increased versatility and all-weather capability.

The latest version continues that formula while adding a more sophisticated approach to all-wheel-drive efficiency.
The ability to disconnect the rear drivetrain during low-load driving can help reduce friction and consumption, while predictive engagement ensures that the driver does not have to manually select four-wheel drive when conditions deteriorate.
That makes quattro ultra particularly well suited to a vehicle intended for long-distance travel, where highway efficiency and predictable traction can be equally important.
