The 2013 Audi A4 isn’t a totally new car, but there are more than enough changes to make it look and feel fresh. Last year’s model was impressive and changes to the 2013 only take those improvements a step further.
Lending a more aggressive look, Audi redesigned the hood and bumper, while rectangular fog lights look sleek in the lower front fascia. Following the industry trend, Audi slapped some LEDs on for the daytime running lights and taillights. A new single-frame grille also helps the car stand out.
Inside the cabin, the 2013 model gets a welcome upgrade over the previous model, which was starting to look outdated. In addition to available wood inserts, Audi developed a modern-looking woven aluminum trim. It dresses up the dash with just a bit of brightness necessary to set off the dark leather.
Great review of the A4.
