Hirotoshi Honda, founder of Mugen Motorsports is the son of Soichiro Honda, the man who founded the Honda Motor Company. Born in April 1942, he was six when his father set up Honda and when Hirotoshi was in his teens, the empire boomed. By the time Hirotoshi graduated from Nihon University in 1965, the Honda name was famous across the world for its motorcycles - and was beginning to build cars. Mugen Motorsports After graduating, Hirotoshi tried his hand at building his own racing cars in workshops behind the family home but it was not until 1972, when Honda began to market the Civic, that Hirotoshi decided on his long-term future. Seeing big opportunities in automobile design, he established Mugen with Masao Kimura, an engineer with experience at Honda R&D and in the Honda Racing team. Mugen Motorsports (M-TEC Co., Ltd) is a Japanese company formed in 1973 by Hirotoshi Honda, the son of Honda Motor Company founder Soichiro Honda, and Masao Kimura. Mugen, meaning "Without Limit", 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. Things were complicated for some time when Mugen was owned and ran by Hirotoshi Honda who has been the major shareholder in Honda since his father's death in 1991. The company 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 lead to Mugen's involvement in Formula 1, from 1992 to 1999, and up to 2005 was the exclusive supplier of Formula Nippon engines. In 1992 the company had built the prototype Honda NSX and has long-term ambitions to build its own road cars. The plan was to develop technology to be used on Honda road cars and develop racing engines for sale. The first Mugen engines were based on the Civic's 1200cc unit, but as the Honda range of cars grew, so did Mugen. By 1984 Mugen had begun to market body kits as well as engines.
