FROM MCLAREN’S WEBSITE:
The best driver’s car in the world must also have exceptional straight-line performance and instant throttle response. To deliver this, the McLaren P1™ uses an innovative IPAS petrol-electric powertrain comprising a substantially revised 3.8-litre twin-turbo V8 petrol engine, coupled to a single electric motor, collectively known as M838TQ. Combined power output is 916 PS (903 hp). As important as absolute power is the electric motor’s ability to provide instant torque, making the powertrain superbly responsive. It is also amazingly efficient. Carbon dioxide emissions are less than 200g/km, and it can cover more than 10 km in electric-only mode.
Top speed is electronically limited to 350 km/h (217 mph), with the 0-100 km/h standing start acceleration taking less than three seconds .The McLaren P1™ will power from rest to 200 km/h in less than seven seconds, and on to 300 km/h in less than 17 seconds – a full five seconds quicker than the McLaren F1.
