What is miles per pound?

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 13 - 32 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.

Even though a diesel engine is available in two outputs neither version is particularly frugal so whichever model you go for fuel costs will be considerable. Insurance and road tax aren’t cheap either while Audi servicing tends to be expensive, especially at main dealers. It’s worth finding an independent specialist which should work out cheaper.

The Allroad is a polluting model. With an average of 286g/km CO2 across the model line-up, its emissions are high for a small 4x4. However, it’s worth noting that the line up has a high number of diesel models, bringing the average down and giving buyers more choices of low-emission versions. Diesels typically produce less CO2 than petrol engines with similar power outputs.

The range is disappointingly thirsty, averaging 24mpg.

Reliability in the A6 tends to be exemplary, with only occasional problems reported by owners since it was launched in 1997. Maintaining a full Audi service history will help this.
