McLaren reveals power, torque and CO2 emission data for the new McLaren P1 hypercar

The hybrid powertrain in the new McLaren P1 hypercar will produce 903bhp and emit less than 200g/km of CO2, the company has revealed. Power will come from a mid-mounted twin-turbocharged 3.8-litre V8 producing 727bhp at 7500rpm and a 176bhp electric motor mounted directly onto the engine.

McLaren also confirmed the P1 engine’s torque figure of 531lb ft at 4000rpm and the electric motor’s instantly available 192lb ft. Peak combined torque of 664lb ft arrives at 4000rpm.

The electric motor’s 176bhp is also available instantly through a specially developed boost system called Instant Power Assist System (IPAS). It is operated by a steering wheel-mounted button and, McLaren says, gives the car the throttle response of a normally aspirated engine.

The engine, which is a revised version of the M838T unit from the MP4-12C, and electric motor drive the rear wheels through a seven-speed dual-clutch automatic gearbox. The P1 will be able to cover up to six miles on electric power alone, drawing on a 96kg battery pack described as having a greater energy density than that of any other car’s.

The battery is mounted on the underside of the P1’s carbonfibre chassis. It can be fully charged in two hours using a plug-in charger that’s stored in the car’s luggage compartment.

McLaren has also confirmed the P1 will feature a Formula 1-inspired Drag Reduction System (DRS) . The DRS, which is operated by a button on the steering wheel, can reduce the rear wing’s angle to lower drag by up to 23 per cent at higher speeds.

Autocar has produced digital books on the McLaren P1 hypercar as well as the F1 and 12C supercars.

Hybrid schmybrid

Do you think that if one asked them nicely (or the cheque was big enough...), McLaren would produce a P1 for a customer without all the electrical rubbish?

It's not really made for the public road is it?, more it's made as a very rich persons toy,a toy to play with when the mood takes you,another car in the collection, the one which will eventually make it's way to the bottom of the Toy box, i'm sorry, as you may have guessed, i'm not impressed, it's a triumph of function over form, a car designed to perform better than the rest,at the expense of looking good,of making you go WOW! when you see one,no,they will all sell of course,and wil probably never see a public road in Britain.
