The online reveal of the facelifted A8 is scheduled for August 21, but Audi has already released official sketches of the car and some information on it's new revolutionary LED turn signals.

The sketches show the A8 will get a consistent makeover, and much of it is related to the new Matrix LED headlights.

The LED high-beam headlights are split into numerous individual, small diodes working together with lenses or reflectors connected in series. Depending on the conditions, they are activated and deactivated or dimmed individually, supplying high-precision illumination.

The bumpers appear to be slightly redesigned and the front grille no longer reaches the lowest point of the bumper. Check out the video below:
