Two decades after McLaren rocked the car world with the ground-breaking F1, here's the benchmark hypercar's spiritual successor – the P1.

The Woking-based manufacturer says the McLaren P1 shares a similar goal to Gordon Murray's 1992 original – to be the best driver's car in the world.

"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.

The 241mph F1 held the crown of world's fastest production car until being finally usurped by the Bugatti Veyron.

The P1 will go on show at next week's Paris Motor Show – as a design study – but McLaren says it will go on sale within 12 months.

No prices are yet confirmed but the internet rumour mill is putting a figure of around £800k on the P1.

It looks like raw figures won't be the P1's prime rasion d'etre either. "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's MD, Antony Sheriff.

More information will be available at the official unveiling on September 27, in Paris.
