The McLaren P1™ will have the combined force of two highly-efficient powerplants, offering the optimum mix of superb throttle response, day-to-day drivability and top speed. A mid-mounted 3.8-litre twin-turbo V8 petrol engine and a highly effective electric motor give a combined output of 916PS (903 bhp) and a maximum torque figure of 900Nm, ensuring instantaneous throttle response through the rev range, more akin to a naturally aspirated engine. Emissions of less than 200g/km on the combined cycle are reduced to zero in full electric drive mode, while the Formula 1-derived DRS and IPAS technologies offer an increase in straight-line speed and an instant boost of power.
PAS and DRS optimise performance and throttle response
The power available via the petrol engine and electric motor is further enhanced on the McLaren P1™ through two steering wheel-mounted buttons which activate the DRS (Drag Reduction System) and IPAS (Instant Power Assist System).
The high power density has been achieved through a combination of high power cells, low pack weight and an innovative cooling system. The battery weighs just 96kg, and is mounted onto the underbody of the high-strength Formula 1-grade carbon fibre MonoCage chassis, which seals the unit in the vehicle, thus avoiding the added weight of any unnecessary battery packaging.
Due to the amount of power being supplied by the battery, complex cooling is required to guarantee cell performance and reliability. The coolant flow is balanced so each cell is cooled to the same temperature across the entire pack.
In addition to the battery being charged via the engine, the McLaren P1™ is also equipped with a plug-in charger which can recharge the battery, from empty, in only two hours. The plug-in charger can be stored in the luggage compartment, although the customer may choose to store it off-board – in a garage or the pits – to save weight.
