We don't yet have a clear shot at the front end, but you can expect a large gaping maw paired with bright LED daytime running lamps, similar in shape to what we see on the A6, no doubt. The real family resemblance, however, can be seen in the character line running down the length of the car. That sharp accent is now a family trademark, and lets the world know you're looking at an Audi (as if the LED-everything didn't tell you already).
Don't get too used to this three-door shape, though. When the next-generation A3 goes on sale in the United States, it will be a four-door sedan, as Audi of America President Johan de Nysschen recently confirmed. The five-door configuration will still be available in other markets, but Stateside, Audi believes a proper four-door will be what makes customers swoon.
