The McLaren X-1 is a concept by British automotive manufacturer McLaren. It was displayed at the 2012 Pebble Beach Concours d'Elegance. It was built for a McLaren customer who already owns a McLaren F1, a Mercedes-Benz SLR McLaren and a McLaren 12C.
It is based on a McLaren 12C, and was built by McLaren Special Operations (MSO). According to Paul MacKenzie, MSO Programme Director, the X-1 has been developed for the past three years. To style the X-1, McLaren used ideas from a 1961 Facel Vega, a 1953 Chrysler D'Elegance Ghia, a 1959 Buick Electra, a 1939 Mercedes-Benz 540K and a 1971 Citroën SM.
