The entry-level 3.0-litre diesel engine gives the A6 Allroad a decent turn of speed, but we prefer the extra flexibility of the more powerful version. The flagship bi-turbo BiTDI engine makes the Allroad almost indecently quick. Every version comes with a slick-shifting automatic gearbox.
Audi A6 Allroad ride & handling
Like the A6 Avant it’s based on, the Allroad is an accomplished motorway cruiser, and feels secure and composed on sweeping main roads. Once the road gets tighter, though, you can’t escape the car’s sheer bulk. Likewise, the ride is at its best at speed, where it’s mostly comfortable; it’s a little firm around town, so you feel bumpy surfaces more than you’d like.
Audi A6 Allroad refinement
The two lower-powered diesel engines are smooth and quiet, while the BiTDI engine has an almost addictive sporty exhaust note. The one serious black mark is the amount of wind noise the Allroad generates at motorway speeds.
