Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 31 - 50 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

The Audi A6 allroad running costs are relatively good considering the size of the car and the 3.0-litre engines available. In terms of fuel costs, the best model to go for is the 201bhp 3.0-litre diesel. This is capable of achieving an average 46.3mpg, according to Audi. Of course, you’re more likely to get something closer to 40mpg but that’s still a decent figure on a large estate that can handle more rough terrain.

Other costs may make things a little pricier. Servicing charges at Audi can be more expensive than the competitors.

Despite being an off-road adapted estate, the Audi A6 allroad emissions and economy figures are fairly respectable. The greenest option in the range is the 3.0-litre 201bhp diesel engine. This emits 159g/km of CO2, which helps it slide just beneath the acceptable figure for making a viable company car. The more powerful 242bhp version of this engine also performs admirably with emissions figures of 165g/km, while the range-topping 309bhp BiTurbo emits a little more at 176g/km of CO2.

The previous version of this car suffered few problems so we expect the Audi A6 allroad reliability record to be just as good. At the same time, many of the components and engines featured in the A6 allroad have been used extensively in other models so are well tested.

For the most part, the manufacturer has a strong record for the reliability of its vehicles. The only concern is that if something were to go wrong then you visiting an Audi dealership to get it fixed could prove costly if you are outside of the warranty period.
