American Solar Challenge is a solar car race across North America. Originally called Sunrayce, organized and sponsored by General Motors in 1990, it was renamed American Solar Challenge in 2001, sponsored by the United States Department of Energy and the National Renewable Energy Laboratory. Beginning in 2005, it is now called North American Solar Challenge with the addition of co-sponsor Natural Resources Canada. It is customarily held once every two years in the summer, though there was a three year gap between the first two races.
