Audi's new A8, official pictures of which were released today, may well share its drivelines and platform with Volkswagen's Phaeton, currently accounting for whole forests as motoring magazines world-wide analyse VW's first attempt at taking on BMW's 7 and Mercedes' S-class. Nothing owners will see or touch in the new A8 has much in common with the Phaeton, and Audi dealers, miffed that the new upstart was launched months ahead of their stablemate, know that they have a trump card coming in the form of the Avant version, previewed at last year's Frankfurt motor show.
