The first day of an auto show is usually the most hectic, but this year, the first day of the 2011 North American International Auto Show in Detroit was by and large one of our busiest. Instead of staggering the major product releases between two or three days, which is the traditional route, nearly every automaker presented today. If you missed any of our coverage, you can check out the important releases below. Tomorrow, you can look forward to a Volvo press conference as well as more in-depth analysis, news and videos of the vehicles we’ve already seen.
