I've never heard of a car having more than a million parts. This Lego Bugatti would be awesomer if it could go faster than 12.4 mph. Being built with bricks might explain its slowness.
"This gives the Chiron somewhat reduced performance compared to the ones Bugatti makes in Molsheim, France. One of those has 1,500hp (1119kW) and a top speed in excess of 261mph (420km/h); the LEGO Technic Bugatti makes just 5.3hp (3.9kW) and tops out at 12.4mph (20km/h)."
