This is the McLaren X-1, a one-off concept built by the British manufacturer, which will make its world debut at the Pebble Beach Concours d’Elegance. Although it appears that the car has plenty of elements borrowed from the McLaren MP4-12C, the company says that, externally, only the glasshouse is carried over from the 12C.
Regarding its dimensions, the McLaren X-1 is 4658mm long – 109mm longer than a 12C, it has a width of 2097mm (with mirrors) – an increase of 188 mm and a height of 1199mm. Kerb weight is almost identical to the MP4-12C, about 1400kg.
As expected, because it is a one-off model, all the components were tooled exclusively for the car and include head- and taillights inspired by the McLaren Speed Marque logo.
