During the GM Engineering Seminar at the National Corvette Museum's C5/C6 Bash, preliminary production data for 2009 was released. Most interesting is the total 2009 model year production through April 21, 2009 which stands at 15,237. This is the lowest amount of Corvettes produced in a single model year since the 9,752 Corvettes built during the first year of the C5 Corvette in 1997 and 20,000 less than the 35,000 Corvette built in 2008. Also included in the report is the penetration for exterior colors as well as some of the more popular options.
