The A8’s blend of performance, comfort and serenity are wedded to a beautifully built, practical and well-equipped interior. In fact, by a whisker, it beats the Mercedes S Class, which shows just how good to drive and be driven the Audi A8 is .Having  larger 19 in wheels, Matrix LED headlights with LED rear lights, front sports seats and rear privacy glass. This 3.0-litre V6 petrol is smooth and quiet, if not quite as refined as the 400d engine in the rival Mercedes S Class. It is a powerful engine and  performance is more than adequate and there’s a healthy swell of acceleration available from low revs.
