Audi launched its A6 Avant in 2011 and gave it a facelift in 2014. It's an elegant luxury estate car that's clever, classy and spacious - if not quite top of the class in terms of boot volume. It's laden with technology and bursting with high-quality features, but is it worth paying Audi's high prices? Find out in our full review.

Cabin layout

How we test ease of driving

To find out how easy a car is to drive, we assess cars across a number of areas from visibility and handling to the layout of the cabin and how smoothly the engine delivers its power.

Performance

Overall
In-gear acceleration
Brakes

How we test performance

We test braking distances and whether the effectivess of the brakes fade with repeat use. Performanc is based on in-gear acceleration.

Comfort and practicality

Overall
Entry and exit
Seat comfort
Ride quality
Quietness
Seat space
Boot space (large cars, SUVs and MPVs)

How we test comfort and practicality

Comfort and practicality includes how easy it is, or not, to get in and out of the car and the maximum height of occupants. We also measure road, wind and engine noise and assess how well the car deals with bumps from large potholes to jittery surfaces like cobble stones.

Euro NCAP

How we test euro ncap

Any car that receives a rating of two stars or less from Euro NCAP is made a Don't Buy. Any car that receives three stars can't be a Best Buy. If a car has been available for more than four years and has not been tested by Euro NCAP, it cannot be a Best Buy.

Safety kit

How we test safety kit

We factor in the safety equipment that’s factory-fitted or optional, along with how well the car protects its occupants and pedestrians in the event of an accident. We also test how easy it is to fit a variety of child car seats.
