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 19 - 34 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.

While it’s a little less than the equivalent Mercedes-Benz or BMW, you take a hit in depreciation as payback for the cheaper list price. The more economical diesel will also hold its value better and overall the A8 will make an appealing used buy (just like the previous model) as time progresses.

The A8 is a polluting model. With an average of 257g/km CO2 across the model line-up, its emissions are quite high for an executive saloon. 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 27mpg. The addition of the 2.8-litre model in late 2007 added a slightly greener option – it emits just 199g/km CO2.

Build quality is lasting, and engines should be pretty reliable, but with so much emphasis on the electrics supporting the A8 (suspension, safety aids, MMI), there could be some major problems should any of it fail.
