Alan’s Bugatti Chiron, 3,599 pieces done

Alan sent photos of his Bugatti Chiron (42083) build and it looks exactly as it should. This is one of the flagship kits in the library, a 1:8 scale replica of the 1,500bhp W16-powered hypercar, and at 3,599 pieces, it earns the 7-8 hours most members put into it.

The W16 engine is the centrepiece. All 16 pistons move in sync as you turn the wheels, and the rear section opens to expose the full engine layout. The active rear spoiler has a push-to-deploy mechanism, and the 8-speed gearbox is fully functional. You can shift it by hand while the model is on the desk in front of you.

Alan’s photos show the blue and black Chiron Sport livery coming together cleanly. This is the kind of build that takes up most of an evening but leaves you with something worth putting on display.

The W16 engine

LEGO built all 16 pistons to move in the correct sequence. Turn the rear wheels and you can watch the engine cycle through. The rear clamshell section opens to put the whole layout on show, which is exactly what you want after spending 7 hours building it.

The active rear spoiler is worth spending a minute on. The real Chiron deploys its spoiler at speed, it’s part of the aeroactive management system on a car that weighs 1,995kg and does over 260mph. LEGO’s version has a mechanical push-to-deploy mechanism that snaps it up cleanly. Small thing, but it’s a nice detail on a licensed flagship.

Scale note

At 1:8, this is one of the largest car kits in the library. The finished model is around 56cm long. It takes up space. Plan for that before you sit down with the box.

Also in the library

Alan has worked through enough of the library now that his photos are useful in a different way to product shots. They show the kit as a builder actually sees it: on a table, built in normal light, with the little mechanical details doing the talking.

If you have built Bugatti Chiron and spotted something I have missed, send it over. The member posts are better when they feel like a record of what people are actually building, not just a list of sets we happen to stock.
