Building upon the 1:8 scale LEGO Technic model currently available for hobbyists, McLaren Automotive recently partnered with the plastic brickmakers to build a full-scale, working adaptation of the P1 supercar. According to their announcement, the final result required 23 specialists from both companies to collaborate over 8,344 hours of development and construction followed by another 2,210 hours of production time. The bright yellow variant includes 342,817 LEGO Technic elements spread across 393 different types—11 of which were molded specifically for the project itself.

Once fully assembled, McLaren entrusted the experimental car to its own team racer, Lando Norris. After arriving at the UK’s Silverstone Circuit, Norris managed to complete an entire lap around the 3.66mi track at a top speed of 40 mph.
