Only 100 examples of the '50' editions will be offered worldwide, with production being split equally with the 12C and 12C Spider.
The McLaren 50 12C and 12C Spider receive both technical and cosmetic upgrades, produced by the McLaren Special Operations division. Power output, however, remains unchanged.
Changes include a remodelled front bumper that increases downforce, more carbonfibre components and a front floor that's constructed from race-derived carbon Kevlar.
Bespoke McLaren 50 'Ultra Lightweight' wheels are fitted, 19inch at the front and 20inch at the rear, which are claimed to save 2kg overall compared to the optional 'Super Lightweight' wheels.
