Audi has released a couple of videos teasing the world premieres of two new models. Judging by their bulk, we’d say the vehicles under the covers are the facelifted third-gen A8 and S8.

The new Audi A8 gets Matrix LED headlamps, a reworked front grille, revised front and rear bumpers, new tailpipe finishers and updated head and tail lamp graphics. New alloy wheel designs and an updated infotainment system are expected.

The videos say an online reveal is set for August 21, before the luxury sedan makes its first public appearance at the Frankfurt show next month.
