The LEGO Technic 42115 Lamborghini Sián FKP 37 is a 3,696-piece 1:8 scale replica of the rarest and most extreme Lamborghini ever built — a V12 hybrid hypercar limited to 63 units worldwide. Moving V12 engine, working gearbox, independent suspension, and stunning exterior accuracy.
Why Collectors Love It
63 Built. 1 In LEGO. The Lamborghini Sián.
The Sián FKP 37 is named for a Bolognese dialect word meaning lightning — and for Ferdinand Karl Piëch, the Volkswagen Group patriarch whose initials the car carries. It was the first Lamborghini hybrid and, at release, the most powerful Lamborghini ever built. Only 63 were produced, matching the founding year of Sant'Agata Bolognese. The LEGO Technic version is the most complex Lamborghini model ever produced — 3,696 pieces replicating every aerodynamic element of the car.
The V12 Engine: 12 Pistons, All Moving
The naturally aspirated 6.5-litre V12 is what makes the Sián special — Lamborghini declined to downsize or turbocharge its signature engine. The LEGO version puts all 12 cylinders inside the car, connected to the rear wheels so they all move in sequence when the car rolls. Building the V12 block — 12 pistons in a V arrangement — is the most satisfying moment of the entire 3,696-piece build.

"A Lamborghini fan and Technic collector. The Sián is more complex than the Bugatti Chiron — 12 pistons instead of 16, but the car's aerodynamic surfaces are more intricate. The yellow colour is perfect. Displayed alongside the Chiron and the Defender — the definitive 1:8 Technic collection."
"3,696 pieces over four days. The V12 engine build alone took an afternoon. When the car was finished and I rolled it across the table and watched all 12 pistons move, it was one of the best LEGO moments I've had. Worth every cent."
