[3] The company tunes and races Honda vehicles in the Super GT championship, and, additionally, sells aftermarket parts to amateur enthusiasts.

Mugen ultimately intends to build its own road cars and the first step towards this was the creation of bodykits for the Honda Ballade CR-X in 1984.

The new company retained the right to use the Mugen trademark and its headquarters in Asaka, Saitama, in the northern suburbs of Tokyo close to the Honda R&D facility at Wako.

In 1989, Mugen entered European F3000 with the MF308 engine and won the championship with Jean Alesi, driving an Eddie Jordan Racing Reynard.

In 1988, Mugen started tuning Honda engines for use in Formula Three, winning the Japanese series with Akihiko Nakaya, and in 1990 expanded their business to Europe.

M-TEC lost the supply contract for the 2006 season, with the rules changing to allow Toyota associate TOM'S to join Mugen as engine supplier.

Although Honda withdrew from the sport at the end of 1992 season, Mugen remained affiliated with Footwork in 1993 and created a B version of the MF351H, used by Aguri Suzuki and Derek Warwick.

The Mugen engine, codenamed MF351HC (also known as ZA5C), was not able to show its full potential and failed to score a single World Championship point during 1994 despite coming close on 3 occasions.

Gary Anderson would years later reveal that, by that season, Honda's headquarters had increased their involvement in developing the engines that otherwise still carry Mugen branding.

[5] The 1999 season resulted in further success with Heinz-Harald Frentzen winning twice in France and Italy and even challenging for the title, although he failed in doing so due to better performance from McLaren and Ferrari.

Mugen chose a 4.0 L (N/A) Naturally aspirated engine because they felt through their experience in Formula Three that restrictor size was key to performance.

The main engines in use at the time were producing around 600 hp, including the turbocharged Audi and Cadillac, as well as the larger displacement BMW and the Roush-prepared Ford.

Team director Junichi Kumakura thought racing the NSX in the United States was a great way to promote the company in a previously unvisited environment.

When asked what else M-TEC would like to accomplish in America with the golden NSX, competing at Sebring and Daytona were marked as attractive goals.

Engine Name: MF458S Mugen have become the dominant force in electrically powered motorcycles competing at the Isle of Man TT Races.

[8] Making their competitive debut at the 2012 Isle of Man TT, John McGuinness took the Mugen Shinden Ni to second place behind the MotoCzysz of Michael Rutter at an average speed of 109.527 mph.

Fielding two machines at the 2014 Isle of Man TT, John McGuinness secured their maiden victory ahead of teammate Bruce Anstey who took second place on the other Shinden San.

The Mugen motorcycles achieved first and third place with Michael Rutter and Lee Johnston respectively, split by Daley Mathison riding for the University of Nottingham.

2019 Mugen achieved their sixth consecutive victory with Michael Rutter again increasing the lap record average speed to 121.91 mph.
