Purchased by me
Over 900 pieces in that black and yellow Bugatti scheme, with pistons you can see and hear move, upward-opening doors, and a sleek supercar shape. The Technic Bugatti was honestly a lot of fun to build.

The verdict
Buy it if
you love supercars and want a sleek Technic model with a working engine and the real Bugatti door action.
Skip it if
you want a pullback motor, or a set with more play functions than looks.
What’s good
- Engine on the back where you can see and hear the pistons move as you push it forward.
- The doors open upwards, just like the real Bugatti cars.
- Sleek, minimal supercar look in the black and yellow scheme.
- Over 900 pieces, and genuinely fun and entertaining to build.
The catch
- No pullback motor, so it doesn’t drive itself across the floor.
- The Technic Bugatti is more of a display supercar than a play set, so don’t expect a ton of functions.

What it is
The Technic Bugatti is a LEGO Technic model of the Bugatti Bolide with over 900 pieces in the car’s black and yellow scheme. The Technic Bugatti is got an engine on the back with pistons that move as you push it forward, and you can flip a panel up to see a bit more of them. There’s a steering wheel on the front, and the doors open upwards just like the real thing.

What I found building it
The look is the first thing that gets you. The Technic Bugatti is sleek and minimal, exactly the supercar shape you’d want. The build was a lot of fun and stayed entertaining the whole way through at over 900 pieces.
The engine is the standout function. Push the car forward and you can both see and hear the pistons working, and flipping the panel up to reveal more of them is a nice touch. There’s no pullback motor here, so this is more about the look and the engine than driving it around.

Who I’d tell to buy it
If you love supercars, this is a great one to build and display. Go in knowing it doesn’t have pullback. If you want a sleek model with a working engine and the real Bugatti door action, I’d really recommend it.

How it did in testing
This is a hands-on after building the set, not a spec rundown. Here’s what stood out, so you can decide if it’s worth it.
The moving pistons and the door action are the highlights. The build itself was a good time.
| Test | What happened | Note |
|---|---|---|
| The engine | Push it forward and you can see and hear the pistons move. | Flip a panel up to see more of them. |
| Doors | They open upwards like the real Bugatti. | A nice authentic touch. |
| Steering wheel | There’s a steering wheel on the front that’s a cool detail. | Adds to the supercar feel. |
| Pullback | There isn’t one. | This one’s about looks and the engine. |

Living with it
The Technic Bugatti is a great set for anyone who loves a supercar. The Technic Bugatti looks really cool, the moving pistons are fun, and the whole build was entertaining.
Just know going in there’s no pullback. If you’re okay with a sleek display model that has a working engine and real door action, it’s an easy recommend.
