According to Tech Crunch, the whole auto is not entirely LEGO (obviously), "there's a steel frame, a pair of batteries, some 3d printed gears, and the whole thing sits on top of actual Bugatti wheels", it says.

It's not anywhere near as fast as a real Chiron, of course - the Lego car's top speed is 20kph - but that's not bad considering Lego didn't drop in a combustion engine, or one from an existing electric vehicle.

It is being called the "LEGO Technic Bugatti Chiron", and it is completely non-glued, self-propelled, and made of entirely of LEGO Technic pieces. It weighs more than 3,300 pounds, has a functional rear spoiler and a top speed of more than 12 miles per hour. But this one is made by LEGO.
