The McLaren P1 is a British limited-production plug-in hybrid sports car produced by McLaren Automotive. Debuted at the 2012 Paris Motor Show, retail began in the UK in October 2013 and all 375 units were sold out by November.
P1 is a mid-engine, rear wheel drive design that used a carbon fiber 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. The P1 features a 3.8 L; 231.8 cu in (3,799 ccs) twin-turbocharged V8 engine. The twin turbos boost the petrol engine at 1.4 bar (20.3 psi) to deliver 737 PS (542 kW; 727 hp) at 7,500 rpm and 531 lb-ft (720 Nm) of torque at 4,000 rpm, combined with an in-house-developed electric motor producing 179 PS (132 kW; 177 hp) and 192 lb-ft (260 Nm) of torque. The car is rear-wheel-drive with a 7-speed dual-clutch transmission developed by Graziano. Power for the electric motor is stored in a 324-cell lithium-ion high-density battery pack located behind the cabin, developed by Johnson Matthey Battery Systems. The consumption is 13l/100km in combined usage, 16l/100km in only petrol engine usage and when only electric, the range is 531km, rechargeable in 2 hours. This is a limited model and probably not obtainable retail.
