In the realm of automotive manufacturing, Bugatti distinguishes itself through an extraordinary commitment to precision, particularly when it comes to working with carbon fiber. The company has extensive experience in the utilization of this lightweight material, tracing back to the 1990s with the introduction of the Bugatti EB 110, one of the pioneering vehicles to feature a carbon-fiber monocoque. Fast forward to 2007, the Veyron Pur Sang showcased the raw beauty of exposed carbon-fiber bodywork, a feature that later became a standard option for the Chiron. Bugatti has provided insights into its intricate process of crafting carbon fiber of such quality that it can be left unpainted.
Constructed from multiple layers of ultra-fine fibers—each approximately one-tenth the width of a human hair strand—carbon-fiber panels depend on fiber alignment for their structural integrity. The orientation of the fibers largely determines the part’s rigidity, particularly in the direction the fibers are laid.
Moreover, the aesthetic design is not to be overlooked. In models where carbon fiber is left exposed, the visible fibers are deliberately arranged to form a fluid pattern that sweeps across the car’s exterior. Bugatti offers nine distinct tinted finishes for the clear lacquer that seals the carbon fiber, allowing the individual fibers to remain prominently visible.
The labor-intensive process of achieving such a high-quality finish often involves considerable trial and error. For example, the largest component, a side panel spanning approximately 6.5 feet, requires almost an entire week to manufacture. The initial step involves placing sheets of carbon fiber into a mold, which is then subjected to a heat treatment in an autoclave at 248 degrees Fahrenheit for roughly two hours. Components that fail to meet the strict aesthetic criteria are discarded.
Per the design team’s guidelines, individual fibers must align at a precise 45-degree angle in a flawless fishbone pattern. Any deviation greater than 1-2 degrees, or the presence of defects such as frays, bumps, or kinks, necessitates remanufacturing the panel. Like other materials, the completed panels must also ensure uniform gaps when attached to a vehicle.
Once a panel fulfills Bugatti’s stringent standards, it receives an initial coat of clear lacquer, which is then meticulously sanded and polished to highlight the fiber weave. Optionally, a colored tint can be applied as a secondary layer, succeeded by up to three additional layers of clear coat for durability.
As production of the Chiron and its associated models gradually concludes, there is little respite for Bugatti’s skilled artisans specializing in carbon fiber. A successor to the Chiron is slated for unveiling in 2024 and is expected to launch in 2026. To meet future demands, Bugatti is expanding its Molsheim, France facility and plans to augment its workforce by 50% in anticipation of the post-Chiron phase.
