The McLaren P1 has one simple goal: to be the best driver's car in the world on road and track.
At the Paris Motor Show, the McLaren P1 shown was described as a design study.
Next year, a production version, which the company aims to put on sale within 12 months, will be revealed.
"The McLaren P1 will be the result of 50 years of racing and road car heritage… Twenty years ago we raised the supercar performance bar with the McLaren F1 and our goal with the McLaren P1 is to redefine it once again," said McLaren Automotive Executive Chairman, Ron Dennis.
"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," said 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."
Sheriff added: "Our goal is to make the McLaren P1 the most exciting, most capable, most technologically advanced and most dynamically accomplished supercar ever made."
The new McLaren P1 has much higher levels of downforce than any current road car – 600kg is achieved well below maximum speed.
That is approximately five times as much downforce as a McLaren 12C. Its margin over most other high performance supercars is even greater.
The McLaren P1's downforce is similar to current sports racing cars, including the 12C GT3 racer.
