Honda Proving Center, California

A field test complex, owned and operated by the research and development division of the Honda Motor Company, until its closing in 2010, when testing operations were relocated to Marysville, Ohio. Despite its large size, the complex strived to keep a low profile and was hard to see from public roads. Facilities included a 7.5-mile automotive track, assembly buildings, and test courses which model the types of roads found in North America.
