The McLaren P1 is a supercar produced by British marque McLaren Automotive. It is a plug-in hybrid with a mid-engine layout. It was first shown at the 2012 Paris Motor Show. It is considered by the automotive press to be the successor to the McLaren F1, utilising hybrid power and Formula One technology, but does not have the same three-seat layout. The P1 has a mid-engine, rear wheel drive design that used a carbon fibre monocoque and roof structure safety cage concept called MonoCage, which is a development of the MonoCell first used in the MP4-12C and then in subsequent models. Its main competitors are the LaFerrari and the 918 Spyder.
