The A6 Allroad comes with relatively large engines, so it’s an expensive car to buy. Those engines are pretty economical, though – over 40mpg in all the diesel-engined models – and resale values are strong (except on the petrol version), which will keep whole-life costs down. The trouble is an A6 Avant offers much the same abilities, but costs thousands less.
Audi A6 Allroad quality & reliability
This car is another example of why Audi has such a fine reputation for cabin quality. The materials, build and attention to detail are faultless throughout, and the overall ambience isn’t far off that of the pricier A8 luxury saloon. The A6 didn’t score particularly highly for reliability in our latest JD Power survey, but it didn't disgrace itself, either.
Audi A6 Allroad safety & security
The Allroad is brimming with safety equipment, including six airbags and stability control. Optional extras include rear side airbags and a system that steers you back on course if you start to wander from your lane on the motorway. The A6 saloon earned the maximum five stars in Euro NCAP crash tests, and the Allroad should be just as safe.
