There is no difference. I ordered the floor mats and they fit perfectly in my 2011 aveo. 2010 Chevrolet Aveo | WeatherTech FloorLiner - car floor mats liner, floor tray protects and lines the floor of truck and SUV carpeting from mud, snow, water and dirt | WeatherTech.com. They are a perfect fit and have supreme quality. These are the 2010 mats, but they work perfectly for the 2011 aveo sedan, also.
