McLaren claim to have designed, engineered and built to be the best driver’s car in the world with the P1; a car that follows in the footsteps of the iconic McLaren F1. The strictly limited production run of 375 was sold within months of orders opening. In October 2013 customer deliveries began and the McLaren P1 became the first hybrid supercar in the world.

The mid-mounted twin-turbo V8 engine is derived from the one fitted to the 12C, but with numerous and significant differences. A unique block casting is used to incorporate the IPAS electric motor, and the use of new larger high-pressure turbochargers. By itself, the V8 produces an already astonishing 737PS, but it has been designed to work in conjunction with the electric motor, which gives seamless performance and takes the powertrain’s combined output to a dizzying 916PS.

The Instant Power Assist System is a powerful electric motor integrated into the powertrain. The motor weighs just 26kg and produces 179PS – more than double the power of a Formula 1™ KERS unit. It boosts performance, whether deployed through the IPAS button on the steering wheel or working automatically, but it also dramatically sharpens throttle response by filling the torque gap as the V8’s twin turbochargers spool up.

The importance of high-speed stability means the McLaren P1™ has been designed to produce more downforce than any other road car. Moveable front and rear wings can produce a peak of 600kg of downforce in Race mode, increasing both grip and driver confidence. The rear wing also incorporates a Formula 1™ inspired DRS (Drag Reduction System), which reduces the wing element’s angle to zero degrees when the DRS button on the steering wheel is pressed, reducing drag by 23 per cent.
