McLaren Automotive has revealed what it calls the company's “ultimate supercar,” the all-new P1. McLaren says the project has one simple goal: “To be the best driver's car in the world on road and track.”

The prototype will be officially unveiled at the Paris Motor Show on Sept. 27. Next year a production version, which the company aims to put on sale within 12 months, will be revealed.

"P1 will be the result of 50 years of racing and road car heritage," says McLaren Automotive Executive Chairman Ron Dennis. "Twenty years ago we raised the supercar performance bar with the McLaren F1 and our goal with P1 is to redefine it once again."

"Our aim is 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," added McLaren Automotive Managing Director Antony Sheriff. "It is the true test of a supercar's all-round ability and a much more important technical statement. It will be the most exciting, most capable, most technologically advanced and most dynamically accomplished supercar ever made."

When P1 goes into production later next year, it will sit above the 12C and 12C Spider, in terms of both price and performance, McLaren says. Specific pricing info was not revealed, but Autocar reports the P1 is expected to cost £800,000 [$1.3m], with production limited to 500 models. Autocar says the car will be powered by a 960hp engine, with the help of a Formula 1-style kinetic energy recovery system (KERS).
