Koenigsegg built the first car with a body of “naked” carbon

Koenigsegg commissioned by a customer from Switzerland built the first car, the body of which is entirely made of a material called KNC (Koenigsegg Naked Carbon). It is a “clean” carbon fiber, from which the epoxy resin layer left over after baking the composite parts in an autoclave is manually removed. This method of carbon processing allowed us to reduce the mass of the hypercar, in this case the Regera, by 20 kilograms.

All carbon fiber hypercar parts in Koenigsegg are treated in three different ways. The exterior panels of the body are sanded and painted with a solid color, clear lacquer or a combination of both. Separate internal parts are polished, and interior elements are usually subjected to the most delicate procedure, when the epoxy resin layer is manually removed from the surface, and the part is processed to give the appearance of the original carbon fiber. The process is very laborious, as a small error in polishing can lead to a violation of the structure of the figure.

It is the latter method that was used to create a unique Regera. Koenigsegg notes that KNC is more scratch resistant because the lacquer coating is much softer than “raw” carbon. In addition, KNC parts reflect light differently, since it does not play on the entire surface, but on each fiber of the carbon fiber.

This method of processing carbon has been improved for several years. It was used for wheels, rear wings, spilitters, winglets and steering wheel trim elements. Before transferring the technology to the entire car, samples of parts for a long time lay on the street. Only in this way Koenigsegg could make sure that the snow and the sun would not adversely affect the texture of the material.
