Audi A6 allroad Gains Its First Plug-In Hybrid, Diesel Stays On

Audi has started taking orders in Germany for the new A6 allroad, and for the first time in the model’s history the rugged estate can be specified with a plug-in hybrid powertrain. Rather than retiring diesel, the brand is keeping a 3.0-litre V6 oil-burner in the line-up, betting that buyers in this niche still want to pick between the two approaches. Both variants route their power through quattro ultra all-wheel drive.

The diesel makes 220kW and now benefits from mild-hybrid assistance plus an electrically driven compressor, a setup aimed at sharpening low-end response. The e-hybrid is the stronger of the pair at 270kW. The emissions gap between them is stark: the plug-in is rated at 53 to 64g/km of weighted CO2, while the diesel sits between 153 and 167g/km.

Pricing reflects the electrified option’s premium. The diesel starts at €77,250 (roughly US$90,383) and the e-hybrid at €80,250 (about US$93,893). Under the skin, quattro ultra is designed to save fuel by running the car in front-wheel drive whenever grip allows. It does this by opening one clutch at the gearbox output and another in the rear differential, disconnecting the rear driveline to cut friction losses. According to Audi, the system anticipates the need for all-wheel drive roughly half a second ahead and re-engages it in about 200 milliseconds.

Audi’s technical development chief Rouven Mohr framed the system’s behaviour as seamless: “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.”

The allroad formula has long mixed estate practicality with raised suspension and all-weather traction, so adding a plug-in option without abandoning diesel fits the model’s dual character. The technology behind quattro ultra dates back to 2016 and now appears on the A5, A6 and Q5 built on Audi’s combustion platform. It also feeds into a broader identity play: Audi has produced more than 15.6 million quattro vehicles, accounting for a third of its total output since 1980. For shoppers in this corner of the market, the new A6 allroad now offers a choice between low-emission electric running and the long-distance strengths of a refined diesel.
