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 25 - 39 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 two diesels give decent fuel economy figures, though the petrols (launched in 2007) are much thirstier. Depreciation will largely be in-line with the standard estate and diesels command a healthy premium over petrols. Audi maintenance does tend to be pricey, but servicing every two years/20,000 miles helps to spread the burden.

The Allroad scores badly on the eco front. With an average of 245g/km CO2 across the line-up, its emissions are quite high for a 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 quite thirsty, averaging 29mpg.

The A6 Allroad impresses throughout with its quality. Top-rate materials are used and it has a feeling of solidity. It’s based on the A6 saloon, which was launched in 2004 and has yet to show any major problems.
