Building a car like the Bugatti Chiron is a complex and all-encompassing process, as this long but very interesting 50-minute documentary from WELT shows.

Each and every Chiron built by the car manufacturer is assembled at the company’s facility in Molsheim, France while the 8.0-liter quad-turbocharged W16 engines are made in Germany. The documentary reveals that there are just eight technicians in the world certified to build this powertrain and just three engines are produced each week. When you consider the engine has roughly 3,700 parts, it’s hardly a surprise why it takes so long to put together.

The extremely detailed documentary takes a look at many of the in-depth processes that go into building the Chiron. Roughly half-way through, we get to see the titanium exhaust system fitted. While there are only four visible tailpipes at the rear of the Chiron, it does actually have two additional tailpipes hidden within the rear diffuser and not visible unless you look under the hypercar.

At one stage in the documentary, Bugatti design director Achim Anscheidt shows off the 3D-printed titanium brake caliper that the company has been recently developing. We first saw this brake caliper back in December 2018 and while it has hit to reach the production line, it is 40 per cent lighter than the brakes currently used by the Chiron.

Regardless of whether or not you think it is worth paying upwards of $3 million for a Bugatti Chiron in the United States, it is fascinating to see the attention to detail that goes into the build process of each one.
