Project Four Racing

Project Four Racing was a British Formula Two and Formula Three team. The team was founded in 1976 by former Brabham mechanic Ron Dennis. At the end of 1980, the team merged with the McLaren Formula One team.

The team name lived on in the designation of the McLaren F1 race cars from 1981 to the 2016 season, all McLarens, starting with the John Barnard designed McLaren MP4/1, had carried the "MP4" name, with MP4 standing for "Marlboro Project 4" and later "McLaren Project 4". The road car McLaren MP4-12C also carried the prefix until it was dropped for the 2012 model year. From 2017 onward, after the departure of Dennis from McLaren, the team began to designate their cars with the name "MCL".
