MCLAREN P1
The McLaren P1 is a limited-production plug-in hybrid sports car produced by British automobile manufacturer McLaren Automotive. Debuted at the 2012 Paris Motor Show,[5] sales of the P1 began in the United Kingdom in October 2013 and all 375 units were sold out by November.[6][7] Production ended in early December 2015.[8] The United States accounted for 34% of the units and Europe for 26%.[8]
The P1 features a 3.8 L; 231.8 cu in (3,799 cc)
twin-turbocharged V8 engine.
[14] 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 N⋅m) 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 N⋅m) of torque. The electric motor and the petrol engine in the P1, produce a combined power output of 916 PS (674 kW; 903 hp) and 723 lb⋅ft (980 N⋅m) of torque. The electric motor can be deployed manually by the driver or left in automatic mode, whereby the car's
ECUs 'torque fill' the gaps in the petrol engine's output, which is considered turbo lag. This gives the powertrain an effective powerband of almost 7,000 rpm.
[15] The car has
rear-wheel-drive layout and is equipped with a 7-speed
dual-clutch transmission developed by
Graziano Trasmissioni.
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 battery can be charged by the engine or through a plug-in equipment and can be fully charged in two hours. The car can be operated using either the petrol engine, the electric motor or with a combination of the two. The P1 has an
all-electric range of at least 10 km (6.2 mi) on the combined European drive cycle.
[16] Under the
EPA cycle, the range in EV mode is 19 mi (31 km). During EV mode the P1 has a petrol consumption of 4.8g/100 mile, and as a result, EPA's all-electric range is rated as zero. The total range is 330 mi (531 km).
[1] The P1 combined fuel economy in EV mode was rated by the EPA at 18
MPGe (13 L petrol equivalent/100 km; 22 mpg-imp petrol equivalent), with an energy consumption of 25 kW-hrs/100 mi and petrol consumption of 4.8 gal
-US/100 mi. The combined fuel economy when running only with petrol is 17 mpg
‑US (14 L/100 km; 20 mpg
‑imp), 16 mpg
‑US (15 L/100 km; 19 mpg
‑imp) for city driving, and 20 mpg
‑US (12 L/100 km; 24 mpg
‑imp) in highway.
