The Audi A6 Avant is a comfortable, quiet and technologically advanced estate that's beautifully built. A BMW 5 Series Touring is better to drive and has a more user-friendly infotainment system, though.
Upgrading to Vorsprung trim adds 21in alloys, keyless entry, heated rear seats, a panoramic sunroof, soft-close doors, adaptive cruise control and black ash interior wood trim, but it also carries a huge price premium, so we wouldn’t bother.
The S6 has a 3.0-litre V6 diesel under the bonnet with 339bhp to give 0-62mph in 5.0sec dead. It has lots of low down urgency and can crack 40mpg according to official figures, too.
