Our Review
LEGO Technic's 42115 Lamborghini Sián FKP 37 is a large 1:8-scale build of 3,696 pieces, with a functioning sequential gearbox and a moving V12 engine. It's a statement piece. Here's the honest take.
Pros
- Striking 1:8 model that looks superb on display
- Working sequential gearbox and moving V12 engine
- Premium details and an authentic Lamborghini silhouette
- Big enough to feel like a genuine centerpiece
Cons
- Flagship price at around $450
- Large footprint to display
- Complex build unsuitable for younger kids
- Like all Technic supercars, the tyres attract dust
Detailed Analysis
Looks first, function close behind
Where the Bugatti leans into mechanism, the Sián leans a little more into presence. At 1:8 scale it's large and genuinely striking, and it still includes the working sequential gearbox and moving V12 that Technic fans expect. It's arguably the best-looking of LEGO's Technic supercars.
A flagship commitment
At roughly $450 and a large footprint, this is a considered purchase, not an impulse buy. The build is long and detailed, rewarding for enthusiasts and daunting for casual builders. If you want the most display-worthy Technic car and have the budget, it's a strong pick.
Final Verdict
A gorgeous, functional flagship that suits enthusiasts who want a showpiece. It's expensive and large, but few LEGO models draw the eye like this one. Worth it if display impact is your priority.
