The new car is being developed under the codename BP23 by McLaren Special Operations, the bespoke division of McLaren Cars, which typically specialises in customising production vehicles to the tastes and whims of high value customers.
BP23 will apparently be a part of the Ultimate Series family and, as such, will have a hybrid drivetrain, dihedral-opening doors, and a carbon-fibre body. McLaren claims that the BP23 will be "the most powerful and most aerodynamic road-going McLaren ever".
That means that it will eclipse the P1, which made its debut in 2013, and featured a 673kW hybrid drivetrain with a 542kW/720Nm 3.8-litre twin-turbocharged V8, a 132kW/260Nm electric motor, and a seven-speed dual clutch transmission hooked up to the rear wheels.
McLaren says that output of the BP23 will be limited to just 106 cars, the same number as the F1. The company expects the first customers will begin receiving their BP23 cars in 2019.
Even if you can afford the expected seven figure price tag, you're out of luck: the entire production run has already been pre-sold.
