Audi's largest luxury sedan is set to receive a nip and tuck soon and the official sketches you see here show off the new front and rear styling.
In addition to new bumpers at both ends, redesigned grille and taillights, the 2014 A8 marks the debut of Audi's new matrix LED headlights.
The big party trick here is indicator LEDs that light up sequentially in the direction in which the vehicle is about to turn, which is said to make it easier for other road users to perceive vehicle's turning intentions at longer distances and in conditions of poor visibility. This trick also applies to the taillights.
During flashing, the blocks are sequentially activated at 20 millisecond intervals, from the inside outwards in the desired turning direction. After 150 milliseconds, all segments are bright; for another 250 milliseconds they illuminate with full intensity. Afterwards, the turn signals go dark before repeating the lighting sequence.
The Matrix LED headlight units also contain 25 light-emitting diodes that generate a highly variable high-beam light that allows certain sections to be masked when the on-board computer detects vehicles ahead.
The lighting entourage also includes navigation-based cornering lights and a 'marker light' that warns the driver of pedestrians in the dark and alerts the pedestrians too.
While Audi has gone into detail about the new lights, the rest of the package will remain a mystery until the vehicle's official reveal on Wednesday, 21 August. Watch this space.
