Lego has previously built functioning engines, but one fan of the Danish toymaker has taken things a step further with a fully operational V8 motor built out of Lego pieces and several custom components.
Dubbed the “world’s smallest working Lego V8,” the engine features original cylinders and pistons from Lego, but they’ve been combined with a bespoke crankshaft and valves, which were designed and made by the builder. Interestingly, the valves were fashioned out of two different tire valve cores.
The crankshaft, however, is partially made of metal and even includes 3D-printed parts. Another Lego engine aficionado made the crankcase, and all these parts come together to create an incredible ode to the internal combustion engine.
