What's it like?
Climb aboard and, in isolation, the cabin is a wonderful place to be, although that hardly sets it apart in this class, and the vast array of buttons surrounding the low-slung driver’s seat offer a vast array of controls in a surprisingly intuitive manner. The small, stubby gearlever is a fiddle to work initially, but this is only a minor quibble.
The LED matrix lighting system is as as impressive as it sounds, providing incredible vision and effectively and automatically sensing and adapting to what's on the road ahead in fractions of a second. It is a genuine leap forward for lighting technology, although it is unlikely to swing the votes of many buyers on its own.
The V8 is a powerful, torque-laden unit that is beautifully effortless for town cruising and impressively sharp yet refined under hard acceleration. What’s more, quattro is now standard on all A8s, and the traction benefits are obvious, especially in the rain-sodden country lanes we chiefly road tested in. It’s refined, too, and the claimed economy is noteworthy against competitors.
The tweaked suspension offers some cause for hope as well. The ride is far more controlled than on the pre-facelifted car with pitch and dive under acceleration and braking reigned in and body control in corners decent, if not class-leading. The overall impression is that this a fast but secure car in which to make progress.
But these positives are undone by lacklustre steering feel. The electro-mechanical system is direct, but the weighting rarely transmits a true sense of what’s going on at the wheels. There is also an issue in dealing with larger road imperfections, which sends everything from an irritating patter to occasional thuds in to the cabin. Wind noise is also a minor issue at motorway speeds.
Should I buy one?
Those shortcomings are enough to leave the Audi in a bit of a hinterland for would-be buyers. This is not, as claimed, the sportiest car in its class (the soon to be facelifted Jaguar XJ is), and nor is it the finest riding or refined (which you suspect matters more to buyers anyway, and is an area where the S-class excels).
Ultimately, there’s no escaping that this facelifted Audi A8 sits in the same class as the new Mercedes S-class, which we recently declared the best car in the world alongside the incomparable Rolls-Royce Phantom. Where the S-class is an all-rounder par excellence, the Audi’s attributes hit too few highs and too many lows.
Even in revised form, the A8 is not a match for the S-class. Undoubtedly a good car though it is, in some areas it is not even close to the class leader.
For many buyers at this rarified end of the market that is where the discussion will begin and – swiftly – end.
