The latest publicity stunt by Lego to boost awareness of its Technic line is this – a 1:1 scale model of the Bugatti Chiron. It took more than 1 million Lego pieces in 339 different types, including a few custom pieces because Lego didn’t manufacture the right type of piece in the right color. It weighs in at 3,300 lbs., although there IS some metal in the build.
Due to the anticipated weight, the thing is actually built on a metal frame and roll cage with regular axles and tires. A few other bits are metal as well – the removable steering wheel uses a regular steering wheel connector, and real seat belts connect to the roll cage. There’s also a steel chain and driveshaft running the rear tires. That’s pretty much the extent of the “cheating” though. Virtually everything else is built from Lego.
That includes the engine – 2,304 individual Lego Technic motors across 24 individually replaceable motor packs drive 4,032 Lego gear wheels to transfer a whopping 5.3 horsepower and 68 pound-feet of torque to the rear tires. The car can reach a top speed of about 19 mph, although the test driver here only took it up to about 12 mph.
Even with the cheats, all the little details are pretty freaking incredible. Lego engines moving a 1.5 ton car, Lego pneumatics raising and lowering the rear spoiler, actual locking doors (all Lego pieces) – and no glue used to hold anything together – it’s 100% held together through traditional Lego attachment methods. Most other models this size use glue to reinforce connections and keep the things from collapsing under their own weight. I’m guessing a lot of the weight is distributed to the steel frame and rollcage though, so I can see why glue wouldn’t be as important here. Overall, a fascinating, impressive project though.
