In 2018, LEGO built a life-size, drivable Bugatti Chiron using over one million LEGO Technic pieces.

The LEGO Technic Bugatti Chiron was developed by a specialized team of designers and engineers at the LEGO factory in Kladno, Czech Republic. The project required over 13,000 man-hours of development and assembly to ensure the structural integrity of the 1,500 kg vehicle. Remarkably, 90 percent of the car is made entirely of LEGO elements, including the engine, chassis, and transparent honeycomb body panels.The propulsion system is a feat of engineering, utilizing 2,304 Power Functions motors and 4,032 LEGO Technic gear wheels. This complex arrangement generates an estimated 5.3 horsepower and 92 Newton-meters of torque. To handle the physical stress of driving, the team used a small amount of steel for the frame and real Bugatti wheels, but the rest of the car relies on the mechanical interlocking of the bricks.In August 2018, the car was tested at the Ehra-Lessien proving ground in Germany, the same track where the original Bugatti Chiron broke speed records. Professional test driver Andy Wallace reached a top speed of 20 km/h (12 mph) during the trial. This project served as a massive marketing demonstration for LEGO Technic, proving that their building system can replicate the complex aerodynamics and mechanical functions of a modern supercar.
