This is a quick and fun remote control modification of the LEGO Technic 42083 Bugatti Chiron.
I wanted to see how this huge car performs with 2 L motors, a Servo and a BuWizz unit. To create some space for the L motors I had to remove the original W16 engine and replace with a more compact one. Didumos69 designed an amazing 1:8 scale W16 engine that fits perfectly in the car. You can find the details and the instructions here:
As you can see in the video the 2 L motors are driving the wheels directly through the rear differential. To drive the wheels through the gearbox a clutch gear needs to be removed from the drive train that protects the gearbox. Since that clutch gear is added at the beginning of the building process I did not want to rebuild the whole car, that’s why I choose this more simple option. The gearbox would require also some redesign to work efficiently with the motors.
You can see below how the two L motors are placed under the new engine. The aim was to change as little as possible, I’m sure the motorization can be done more efficiently.

This is how the Servo motor fits in the front. I had to sacrifice the luggage space.
The most simple solution to find some space for the BuWizz unit was to put it in the driver’s seat, so Mr. BuWizz the car’s happy owner was born 🙂
