We have seen some wild engines over the years—quad-turbo monsters, screaming V12 powertrains, and, of course, the legendary W16 from Bugatti. But this? This might be the craziest take yet. Because someone built a fully functioning 16-cylinder engine so small and it's incredible. This W16 Engine Is Not In A Car Bugatti / Jacob & Co.What makes this thing so insanely cool is that it isn’t just for show. The miniature W16 is an automaton, which means when you activate it, the tiny pistons start moving in a synchronized dance that mimics a real internal combustion engine. There’s no fuel or fire involved, obviously, but the visual effect is wild enough to make any car enthusiast do a double take. It’s basically like watching a Bugatti engine come to life in miniature form, and somehow, that is always going to intrigue us. Built Like A Hypercar, And A Watch This video dives into the making of the Bugatti Chiron Tourbillon, a collaboration between Bugatti and Jacob & Co.. At first glance, it genuinely looks like a scaled-down version of the legendary W16 that powers Bugatti’s hypercars. The proportions, the layout, the way each component is assembled—it all feels like it belongs in an engine bay, and not on someone’s wrist.The level of detail here is what really sends it over the edge. The entire movement, known as Caliber JCAM37, was designed to look and feel like an actual engine. The structure echoes exhaust systems, the power reserve is styled like a fuel gauge, and even the layout of the components reflects Bugatti’s signature engineering philosophy. It commits fully to the idea of turning a hypercar powertrain into wearable mechanical art. The Engine Costs As Much As A Brand New Ferrari Bugatti / Jacob & Co.Most reliable reports and official listings from Jacob & Co. place its price at around $280,000 to $300,000, depending on the version and materials. Some highly customized or limited variants can go even higher, especially when buyers start adding bespoke touches.So yeah, that tiny 16-cylinder “engine” on your wrist costs about as much as a fully loaded supercar, and that honestly makes it even more wild.
