Mugen has a long history of modifying and creating body kits for Honda. At the end of 2008, they presented a body kit for the new Accord and Civic. Mugen Motorsports is a Japanese company formed in 1973 by Hirotoshi Honda, the son of Honda Motor Company founder Soichiro Honda. The company is an engine tuner and parts manufacturer closely associated with the Honda Motor Company. Despite the family connections, however, Mugen is not, and has never been, owned by Honda.
Mugen tunes and races Honda vehicles in the Super GT championship, and, additionally, sells aftermarket parts to amateur enthusiasts. It was part of partnerships that won the Formula 3000 championship in 1990 and 1991, and that eventually led to Mugen's involvement in Formula 1, from 1992 to 2000, and up to 2005 was the exclusive supplier of Formula Nippon engines.
