Details of McLaren's long-awaited successor to the legendary McLaren F1 have emerged ahead of its global unveiling at the Geneva motor show next year.

Makers of the million-dollar supercar, code-named P12, aim for its performance to eclipse that of every hypercar, including the Lamborghini Aventador and the successor to the Ferrari Enzo.

The head of McLaren, Ron Dennis, says the F1 successor will be the world's most technologically advanced supercar.

''It will be a relatively low-volume - between 300 and 500 - car that will be more expensive and we hope will be hailed as the most innovative, creative supercar of its time,'' Dennis said in a recent interview.

''A big quantum leap, and very different to this car [the 12C].''

The P12 is expected to be powered by a 5.0-litre version of the McLaren MP4-12C's twin-turbo V8 mounted behind the cabin, and retuned to deliver about 600kW and 800Nm (up from 441kW and 600Nm).

As per the 12C, it will be mated to a seven-speed dual-clutch gearbox to send power to the rear wheels for a 0-100km/h time of less than 3.0 seconds.

It is likely this engine will be coupled with a kinetic energy recovery system (KERS), for better performance and fuel efficiency.

Also taken from the 12C are active aerodynamics and a carbon-fibre ''monocell'' chassis, as well as a roof-mounted air intake.

One radical difference, however, will be the aggressive styling. The P12 will be lower, longer and wider, and although elements of the F1 will carry over, Dennis isn't worried about keeping a family resemblance.

''I'm not fixated by something like a grille shape or a headlight shape that you've got to see,'' Dennis said.

''I am relaxed with the only semblance of family feel being the logo on the car; because we're too low volume to worry about that.''

The P12 will have two seats instead of the F1's three.
