The B8.5 A4 received changes to the front and rear fascia, the entire front end was updated to incorporate a newer grille design and lighting with distinctive new LED running lights. Sadly the Avant version of the A4 was discontinued in the US with the B8.5 update though Audi did bring it back in a way with the (A4 based) B8 allroad. A tune, coilovers and wheels really transforms the car making it more fun to drive and giving it a sporty yet elegant European look.
