Audi A6

Inside, Audi has spent some time ensuring the new Avant is more flexible than its predecessor. Two rails on either side of the floor of the load area can be used for securing loads or, alternatively, provide mounting points for a bike rack or a telescopic bar to hold your shopping in place. For the most part the system works well.

However, it isn't perfect. The bar can be awkward to slide back and forward, and it's a shame most of the adaptable parts aren't standard kit. Our car came with the telescopic bar and a retaining strap, which costs an extra ΂£85.

The boot itself is big enough for most people's needs, though, with 65 litres more space than BMW's 5-Series. Elsewhere, the cabin is superb, offering stunning build quality and a spacious rear. The back seats are easy to fold, although they won't go totally flat.

The A6 Avant still lacks the dynamic qualities of the 5-Series, but as a fashionable premium executive estate it'sa worthy contender in this class.
