Given how comprehensive this latest set of pictures is, it’s hard to believe they are ‘leaked’ rather than deliberately ‘seeded’, but either way they now reveal the a huge electro-mechanical rear wing which provides downforce at high speeds, but perhaps also acts as an air brake – as it did in the Mercedes-Benz SLR McLaren.
However the detail shots of the McLaren P1 Concept’s rear diffuser show that most of the ‘clever’ aerodynamics operate beneath the car, with rumours that its deep side vents may in fact feed a blown diffuser system, as used to great effect in F1 by Adrian Newey’s Red Bull Racing team.
Air flow and its harvesting feature strongly throughout the P1′s contours, with the horizontally-oriented air ducts shaped to mimic McLaren Automotive’s logo (or perhaps the logo is shaped to mimic the air ducts).
The McLaren P1 is cited officially as a concept, with the simple goal of being “..the best driver’s car in the world on road and track.”
Costing around £800,000, the P1 weighs less than 1,300kg and will be powered by the same 3.8-litre twin-turbo V8 as in the 12C, but using a new flywheel-assisted turbo mechanism to deliver higher levels of boost, while capturing and deploying energy using an F1-derived KERS device.
Power is expected to rise from the 626bhp of the 12C to around 800bhp, which will be further enhanced by the 160bhp delivered by its electric motor, which will be fed via KERS and used in short accelerative bursts.
Managing Director Antony Sherriff, laid out his vision for the McLaren P1 last week, “To make the most exciting, most capable, most technologically advanced and most dynamically accomplished supercar ever made – not necessarily to be the fastest in absolute top speed but to be the quickest and most rewarding series production road car on a circuit.”
Executive Chairman Ron Dennis added, “Twenty years McLaren we raised the performance bar for supercars with the McLaren F1. Our goal with the McLaren P1 is to redefine it once again”.
The car will be official unveiled tomorrow, at the Paris Motor Show, when we’ll discover more about the P1′s unique powerplant and hopefully see what it looks like inside.
