The verdict
The Sián FKP 37 delivers exactly what serious Technic builders want: authentic mechanical functions built from LEGO pieces, not shortcuts. It's expensive and demands display space, but as an engineering-focused adult build it holds up.
Pros
- Working 8-speed sequential gearbox with paddle shifters mimics real automotive engineering, not a toy simplification
- V12 engine block has moving pistons visible through the opening rear hood, plus opening scissor doors like the real car
- Presented in genuinely premium packaging with gold-tone rim details, matching its position as a display centerpiece
- 1:8 scale accuracy makes it one of the more visually striking Technic supercars LEGO has produced
Cons
- At roughly 12 cents per piece, it's priced at the very top of the Technic lineup — a serious investment for a static shelf piece
- No motorization included; every function (steering, gearbox, doors) is manually operated, unlike some newer Technic sets
- Requires real display real estate once built — this isn't a set you tuck onto a crowded shelf
- Small suspension and axle components are fiddly to seat correctly and easy to lose during the build
The Lamborghini Sián FKP 37 sits near the top of LEGO's Technic supercar lineup, built around the same philosophy as the brand's Bugatti and Porsche flagship sets: replicate real automotive mechanisms in plastic rather than just the car's shape. This review draws on LEGO's published set specifications and the consistent themes across independent Technic reviews and long-term owner feedback since its release.
The mechanics are the whole point
What separates this from a display-only model kit is that the 8-speed sequential gearbox actually shifts, the steering wheel actually turns the front wheels, and the V12 engine's pistons actually move when you push the car. None of it is motorized, so every function is driven by hand, but that's arguably more satisfying for builders who want to understand how the mechanism works rather than watch it run automatically.
The price-per-piece reality
At its roughly $450 retail price for 3,696 pieces, this set sits well above LEGO's typical Technic price-per-piece ratio, and that premium is a fair trade-off to flag before buying — you're paying for licensing, gold-tone detail elements, and premium packaging as much as raw brick count. Builders chasing value per piece will find better ratios elsewhere in the Technic range.
Who it's for
Best suited to adult Technic collectors who specifically want the engineering-replica experience and have both the budget and a dedicated display spot for a large finished model. Skip it if you want motorized features out of the box, or if price-per-piece value matters more to you than licensed supercar styling.
Frequently asked
- Does the LEGO Lamborghini Sián have working functions?
- Yes — an 8-speed sequential gearbox with paddle shifters, working steering, opening scissor doors, and a V12 engine block with moving pistons, all operated manually rather than motorized.
- How long does the Sián FKP 37 take to build?
- Most adult builders report somewhere in the 15-20+ hour range spread across multiple sessions, given the 3,696-piece count and the density of the mechanical sub-assemblies.
- Is this set motorized?
- No. Every function — gearbox, steering, engine pistons, doors — is driven manually by moving the model or operating built-in controls, unlike some other high-end Technic sets that add a Control+ motor kit.
- Is the Lamborghini Sián FKP 37 worth buying?
- Yes, if you specifically want the mechanical-engineering build experience and have the budget and shelf space — it delivers genuine automotive functions in brick form. It's harder to justify if you just want a static supercar shape at a lower price point.
