The McLaren P1 is a limited production plug-in hybrid sports car by British manufacturer McLaren Automotive. The concept car debuted at the 2012 Paris Motor Show. Deliveries to retail customers began in the UK in October 2013. The entire P1 production of 375 units was sold out by November 2013. The production run ended in December 2015. It is considered to be the long-awaited successor to the McLaren F1, utilizing hybrid power and Formula 1 technology. It does not have the same three seat layout as its predecessor. The design of the headlights is very similar to the shape of the McLaren logo. Just like the McLaren F1 road car of 1992, the McLaren P1 is a mid-engine, rear-wheel drive design that uses a carbon fibre monocoque and roof structure safety cage concept called MonoCage, which is a development of the MonoCell used in the current McLaren 12C Coupe and McLaren 12C Coupe Spider upgrade that came out in early 2012.
