P1 [Official] McLaren P1 Supercar

[martinbo]

Very interesting. That battery pack does look enormous relative to the size of the engine.

DRS and KERS buttons...

 

[Mafalda]

Official specs:
Engine petrol: V8 twin turbo (from MP4-12C): 737ps @ 720 Nm
KERS: 179ps an 260 Nm
overalll 916ps!!!

...even so, this iis a surprise: New ferrari F150'll be more powerful (my bet was P1 a little bit powerful than F150)
petrol engine surely >740ps (rumored about 800ps)
KERS rumored @ 150ps (according with ferrari: claimed about 150 Kgs, and 1 Kg/ 1ps ratio)
overall'd be around 940-950ps

We have the figures, now we need to know the weight of the P1, I am guessing it will be around the same or slightly heavier than the MP4-12c.

You don't think they'll be able to match the F1's weight?

 

[Monster]

More information from EVO, the batteries weigh 96kg, no word on the weight of the motor yet. I don't think they can match the F1's weight because of the inclusion of the hybrid system, plus the heavier dual clutch gearbox.

McLaren has revealed the highlights of its new P1 supercar’s technical details. Its hybrid drivetrain, dubbed ‘twin power’ by McLaren, produces a total output of 903bhp – comfortably making it one of the most powerful cars on sale – while emitting less than 200g/km of CO2, placing it in the same tax band as 2-litre 4-cylinder hatchbacks.

Its massive power output comes from the combination of a 3.8-litre twin-turbo V8, the unit from the McLaren MP4-12C wound up from 616 to 727bhp, and a 176bhp electric motor which is mounted directly onto the engine. The torque figures for engine and motor are 531lb ft and 192lb ft respectively, though their combined peak is 664lb ft, which is delivered from 4000rpm. The electric motor’s response means its power and torque are instantly available courtesy of an IPAS (Instant Power Assist System) button on the steering wheel. A DRS (Drag Reduction System) button also deploys the same aerodynamics-utilising technology seen in Formula 1, the P1’s wing reducing its angle to lower drag by 23 per cent.

Despite its high output, the McLaren P1 is rear-wheel drive (the 1000bhpBugatti Veyron being four-wheel drive) with power channeled through a seven-speed twin-clutch gearbox. McLaren claims the electric motor assists quicker upshifts, dropping engine revs quicker than normal by applying negative torque.

The McLaren P1 can run in electric-only mode, though for around seven miles rather than a full commute. With the motor’s 176bhp output, it should still prove more than brisk enough for urban usage, with the appeal of zero emissions. The battery which energises the motor weighs 96kg and sits in the middle of the car, mounted to the underbody of the carbon monocell chassis (see diagram, right). It is charged by the engine, but can also be plugged into the mains and brimmed from empty in two hours

96 Kgs? as weight as F150, maybe the leletric-engine is bigger

 

[sako97]

The Turbos on the P1 are much larger than the on the 12C.

12C left, P1 Right:

I wouldn't hestitate to say that the 3.8TT is the best TT engine to ever grace a production car thus far.

Did you get to see the concept when it was in NYC?

 

[Deckhook]

I honestly thought that acceleration times had peaked with the Veyron SS but it appears that manufacturers themselves feel this point hasn't been reached yet. I can only imagine that the vast majority of it's owners won't be able to scratch the surface of the performance on offer but then was that ever really the point in these cars.

One thing I did find odd was the way it's DRS system worked, I understand the pressing a button to activate it but it appears (according to the info in WCF) that it only stay active whilst the button is continued to be pressed so not only are you holding on to the wheel but have (I assume) a thumb or finger firmly pressed on this button.

Did you get to see the concept when it was in NYC?

I believe the NYC preview was restricted to prespective customers and journalists only. I'm neither, but hopefully (I doubt it) the production car will be shown at NYIAS as I will be reiceving press passes.

Dear Adam
With just over two weeks until we show the world the McLaren P1™ at the International Motor Show in Geneva, we’re excited to share with you the first details on the car’s dual powerplant system.
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. The substantially revised 3.8-litre twin-turbo V8 petrol engine and a highly effective electric motor, developed in house by McLaren, give a combined output of 916PS and a maximum torque figure of 900Nm.
To optimise efficiency of the petrol engine in the McLaren P1™, extensive testing and development work has always been carried out with our technology partner Mobil 1 on lubrication and hydraulic fluids.
The instant response of the unique electric motor, developed in house by McLaren Electronics, provides a sharper throttle response, and the enhanced air-charging system enables the McLaren P1™ to have more top-end power – the perfect combination for high performance.
The electric motor is mounted directly onto the engine, and all drive is channelled through the dual-clutch seven-speed gearbox to drive the rear wheels. Thus, the electric motor and 3.8-litre twin-turbo V8 petrol engine work seamlessly together, providing more than just added ultimate power and torque.
E-mode
The McLaren P1™can be driven in a variety of modes, powered by the engine and electric motor together, or solely by the electric motor. In E-mode, the McLaren P1™ can travel more than 10km with electric-only power – enough for most city journeys.
DRS and IPAS 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; The Drag Reduction System (DRS) used on the McLaren P1™ is a technology similar to that employed on Formula 1 cars. Speed is increased by reducing the amount of drag on the rear wing by 23 per cent.
Instant Power Assist System (IPAS) is designed to deliver power rapidly for high performance acceleration, providing up to 179PS of instant additional power. This is achieved through a groundbreaking, lightweight battery pack.
We look forward to sharing further details of the McLaren P1™ in the next two weeks, before the production-ready car makes its world debut at the Geneva Motor Show next month.

The brakes are interesting, no holes, vents nothing.

 

[Deckhook]

^Aren't F1 discs similarly without holes or vents?

 

[LaArtist]

Very interesting..
Ile put this on my to read list after Milan v Barcelona

 

[paxah]

Yes - Carbon/Carbon brakes from Akebono. Very interesting!

 

[LaArtist]

Thats some brutal specs.. but the weight will be the deal breaker..lets see where it ends up..

South of 1400kg or north..
