The Mould King building block set of the Lambo V12 engine offers technology enthusiasts a challenging building experience. Made from 1260 precise building blocks, it creates a detailed functional model featuring a longitudinally mounted, manually shiftable 4-speed transmission. The centerpiece is the naturally aspirated V12 engine with twelve moving pistons, bright yellow valve covers, and chrome-plated manifolds. Thanks to the included electric motor and battery box, the powerplant can be driven electrically. The synchronized movement of the camshaft, timing chain, and crankshaft produces a realistic mechanical sound. This impressive display piece measures over 36 centimeters in length and can be flexibly combined with conventional building blocks.
