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.
S line trim brings larger 19in alloy wheels, sportier looks, tinted rear windows and leather and Alcantara seats. We reckon it's the pick of the range.
A more powerful 261bhp version of the 2.0-litre petrol found in the 40 TFSI, the 45 TFSI comes exclusively with quattro four-wheel drive to help it crack 0-62mph in 6.0sec dead. Economy is mid-high thirties, though.
