Costs, insurance groups, MPG and CO2
Fuel economy is also competitive, although, more often than not, an equivalent 5 Series emits less CO2, making it slightly cheaper to run as a company car.
Equipment, options and extras
Entry-level Sport trim gets you most of the luxuries you’re likely to want, including heated front seats, part-leather upholstery, keyless start and 18in alloy wheels.
Upgrading to S line trim brings 19in alloy wheels, sportier looks, tinted rear windows and leather and Alcantara seats, while Black Edition adds even larger 20in alloys along with bespoke styling touches.
Meanwhile, range-topping Vorsprung trim is ludicrously well equipped, with whopping 21in alloys and a panoramic glass roof fitted as standard. It's very expensive, though, so we'd stick with Sport or S line.
Although we don’t yet have specific reliability data for the latest A6, Audi finished a mediocre 20th in the 2019 What Car? Reliability Survey – behind Volvo, but ahead of BMW, Jaguar and Mercedes.
Mind you, the A6 Avant is covered by a warranty that lasts for three years or 60,000 miles, whichever comes first, whereas BMW, Jaguar and Mercedes all provide three-year warranties with no mileage limit.
Safety and security
All versions of the A6 Avant come with a minimum of six airbags and a host of electronic driver aids, including an automatic emergency braking system that can recognise pedestrians as well as reduce the chances of you running into the car in front.
Those features helped it secure a five-star (out of five) rating from Euro NCAP, with high scores for both adult and child occupant crash protection. Range-topping Vorsprung trim get extra safety aids, including blind spot monitoring, although these can be added to other trim levels.
An alarm, engine immobiliser and deadlocks (which prevent a door from being opened, even if the window is smashed) are fitted to every A6 Avant to ward off thieves.
