  • Servicing could be pricey

The A6 Allroad is a big, powerful estate car with Quattro all-wheel drive, so it’s not going to be the cheapest to run. That said, both the 45 TDI and 50 TDI engines claim up to 37.7mpg, and we found well over 40mpg is achievable on a long, relaxed motorway run.

The Allroad isn’t really a car best suited to being driven in Dynamic mode where it’ll consume more fuel, so it’s entirely possible you could regularly see around 40mpg, and be able to cover over 500 miles on a tank of diesel.

In terms of CO2 emissions, both versions of the V6 diesel produce 153g/km in Sport specification with 19-inch alloys. Those with larger 20-inch items on Vorsprung models emit 156g/km.

Is it reliable?

  • No recalls for the A6 Allroad so far
  • Looks to be solidly put together
  • Lots of tech, but should be dependable

The Allroad comes packed with a vast array of advanced technology that’s only been fitted to Audi models for a couple of years at the time of its launch, but old gremlins with previous versions of the firm’s Virtual Cockpit look to have been eradicated with the newer system. Similarly, we haven’t experience any issues with the new touchscreen interface either.

Sometimes the driver assistance tech can become disrupted and throw up warning lights that sensors aren’t working or cameras can’t be used, but that can be down to weather conditions such as fog. If it persists then get it checked, but we’ve not seen any big issues yet.

Otherwise, the Allroad should prove to be a dependable family workhorse. The interior quality feels top-notch and the mechanical components are fitted to many other cars in the range. If anything does go wrong early days, the A6 comes with a three-year, 60,000-mile warranty.
