In what may be the most awesome LEGO project ever, the company has announced the world premier of a full scale functional replica of the Bugatti Chiron supercar built almost entirely from LEGO Technic parts, including its 5.3 horsepower electric motor.
The car is build around a minimal metal frame using over a million LEGO parts and weighs in at about 3,300 pounds (1,500 kilograms) which is 1,100 pounds less than the real car. The 339 distinct part types were assembled without glue.
The designers managed to recreate the Chiron’s flowing curved surfaces by assembling an outer skin made of various geometrical primitives built out of standard LEGO Technic parts. The skin is then attached to deeper layers of LEGO framing using adjustable attachment points.
The electric motor drive consists of multiple modules that each contain a 7 by 7 matrix of standard LEGO Technic motors which are then assembled together and geared to a chain drive that spins an output shaft and ultimately the tires.
Altogether, the 2,304 LEGO motors collectively throw off a theoretical 5.3 horsepower (4 kW) with 68 pound-feet (98 Nm) of torque. That’s enough to speed the car to a full 12 MPH (20 KMH).
The real Chiron has a 1,479 HP (1,103 kW) gasoline 16 cylinder engine with 1,180 pound-feet (1,600 Nm) of torque that can go from stationary to 240 MPH (400 KMH) and then to a full stop again in only 42 seconds.
There is no word on whether the car implements regenerative braking but it’s LEGO plastic disk brake rotor and caliper are said to be fully functional.
Aside from the inner metal frame, the only other major components on the car that are not built from LEGO parts are said to be the tires and wheels.
No details were given for the battery pack size or construction. It’s not known if it supports CHAdeMO or CCS fast charging. Slow charging at 120V seems more likely.
A video from LEGO shows how the car was designed and built. After a brief diagnosis and correction of its motor’s gear chain, the car takes a successfully run on the track driven by Andy Wallace, the real Bugatti Chiron’s official test driver.
