The McLaren P1 is a limited-production mid-engine plug-in hybrid sports car produced by British automobile manufacturer McLaren Automotive. Debuted at the 2012 Paris Motor Show, sales of the P1 began in the United Kingdom in October 2013 and all 375 units were sold out by November. Production ended in early December 2015. The United States accounted for 34% of the units and Europe for 26%. Parts of the car were inspired by a sailfish that Frank Stephenson saw when on holiday in Miami.
