The only thing left to know about the upcoming supercar from the British company, McLaren, was the engine and respective performance figures, and today that information was revealed along with some explanations on the operation of the hybrid engine.
The mid-mounted 3.8 liter twin-turbo V8 petrol engine works in conjunction with an electric motor for a combined output power of 916PS (903bhp) and a maximum torque figure of 900Nm (664lb/ft). The petrol engine is the familiar M838T unit that alone produces 737PS (727bhp) at 7500rpm, and 720Nm of torque from 4000rpm, meaning the electric engine is responsible for 179PS (176 bhp) with 260Nm of torque being available from a standstill.
The electric motor is directly connected to the petrol engine and they are mated to a dual-clutch seven-speed gearbox that drives the rear wheels.
The CO2 emissions are under 200g/km and will be zero when only the electric engine is working. The P1 utilizes technology taken from the Formula 1 like the IPAS (Instant Power Assist System) and DRS (Drag Reduction System) offering an instant boost of power and raising the straight-line speed.
