This is the first official photo with the new generation 2012 Subaru Impreza which will debut in both 4-door and 5-door body styles at this year’s New York International Auto Show.
We can’t say much about the 2012 Impreza based on this single side image, but according to Subaru, this new design will "provide a roomier interior and improved levels of comfort and refinement." It is easy to see that the front and rear end have been completely revamped, but we’ll be able to draw our conclusion once the car gets fully unveiled (April 20th, 2011 at 13:05h).
Technical specification are also unknown at this point, but the Japanese automaker did mention that based on their in-house data, the 2012 Subaru Impreza will be able to return 36 mpg on the highway (the equivalent of 6.5-litres of fuel per 100 Km).
