McLaren 50 12C & 12C Spider celebrate McLaren’s 50th anniversary

McLaren say they will be building a maximum of 50 each of the 50 12C Coupe and 12C Spider to mark the occasion, both of which get special features provided by McLaren Special Operations – the same McLaren division that created the 12C High Sport. That means a new front bumper which has been optimised by Computational Fluid Dynamics (CFD) for more downforce, extra carbon fibre and kevlar exterior bits, ceramic brakes, 19″ front and 20″ rear alloys, full leather, extra carbon fibre in the cabin, a heritage badge and a numbered plaque. There will be the option of three colours for the 50th anniversary 12Cs - Carbon Black, Supernova Silver and, of course, McLaren Orange – and each car will get its own silver car cover, a limited edition key in a carbon fibre box and a signed art print (sadly, there’s no sign of a tool chest or Tag Heuer watch).

Based on a 2013 Mazda MX-5 2.0-litre Sport Tech Roadster Coupe, the BBR GT270 will reach 60mph in 4.9 seconds and hit an electronically limited top speed of 150mph.
