The car isn't a big surprise anymore. Audi already gave us a sneak preview with the introduction of the conceptcar A1 Metroproject quattro and the A1 Sportback concept. When the A1 hits the market, early 2010, the car will look very much the same as the conceptcars.
We can't say it for sure but we expect the car to be launched at the Tokyo Motor Show. Tokyo was also the place were the A1 concept was launched in 2007. We shall see!
