[1][2] The car is designed to be an "extreme expression of track driving engagement", and will be limited to 25 units, all of which come with a custom moulded seat, FIA-homologated race suit, helmet, and a bespoke HANS (head and neck support device).

[3] The 5.2 L (320 cu in) V10 is a Judd-derived block, which McLaren claims produces in excess of 840 PS (829 hp; 618 kW) and 650 N⋅m (479 lb⋅ft) with a redline of 10,000 rpm.

[4] The engine has individual barrel-driven throttle bodies, with gear-driven camshafts, bespoke crank, intake and exhaust systems.

[5] The gearbox is of aluminium-magnesium construction and consists of straight-cut gears, with a carbon fibre clutch, and with the engine the two will act as stressed members.

A large front splitter, Venturi tunnels integrated into the floor, a twin-element fixed rear wing all combine to give the car a claimed downforce figure of 1,200 kg (2,646 lb) at top speed.
