Default The Official ZeroToHundred McLaren P1 Thread



The McLaren P1 was unveiled to the world as a design study at the Paris Motor Show in September 2012, and was met with the glare of a thousand camera flashes. Since then, development of the technology beneath the carbon fibre skin has continued at great pace. The team at McLaren Automotive has continued the relentless testing programme for the car. The goal being: to produce the best driver's car in the world on road and track.

Published on Feb 6, 2013
McLaren Automotive has taken the opportunity to give a glimpse of the, so far unseen, interior. The latest insight confirms that the McLaren P1™ will adopt a race-inspired digital dash readout, and gives further information relating to the levels of performance that can be expected with a highly-focused 'Race' mode.

-IPAS (Instant Power Assist System) and DRS (Drag Reduction System) offer instant boost of power and straight-line speed

-916PS (903 bhp) and 900Nm, with emissions of less than 200g/km

-Substantially revised 3.8-litre twin-turbo V8 petrol engine coupled to low-weight, highly efficient electric motor ensures instant torque for optimised throttle response

-Full E-mode offers in excess of 10km emission-free driving

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. 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 (664 Ib/Ft), 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.

The 3.8-litre twin-turbo V8 petrol engine in the McLaren P1™ is a new version of the familiar M838T unit, that has been significantly upgraded to optimise cooling and durability under the higher loads. The engine block has a unique casting to incorporate the electric motor. The petrol engine produces 737PS (727 Bhp) at 7,500rpm, and 720Nm (531 Ib/Ft) of torque from 4,000rpm. To optimise efficiency of the petrol engine, extensive testing and development work has always been carried out with McLaren Automotive technology partner Mobil 1 on lubrication and hydraulic fluids.

The lightweight electric motor, developed by the McLaren Electronics arm of the Group, produces 179PS (177 Bhp), and is unique to the McLaren P1™. The motor produces maximum torque of 260Nm (192 Ib/Ft) instantly from a standstill, greatly increasing the throttle response of the McLaren P1™, and peak combined torque of 900Nm (664 Ib/Ft) is delivered from just 4,000 rpm. In addition to this, the McLaren-developed ‘boost’ system, IPAS, provides up to 179PS instantly. The instant response of the electric motor provides a sharper throttle response more associated with a normally aspirated engine, and the significantly 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.

A further benefit is that the e-motor can provide faster upshifts. This is achieved through the application of instant negative torque at the point of shift, making the engine revs drop as quickly and efficiently as possible to the required engine speed for the upshift.

In addition to the obsessive weight-saving measures demonstrated throughout the McLaren P1™, so too is the optimisation of usable energy. When off-throttle the electric motor provides additional drag torque, recovering energy to the battery that would otherwise be lost to the brakes.

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.
