“Bugatti is all about French-style luxury and exceptional vehicles, but it’s a brand that stands for innovative technology, too,” says Stephan Winkelmann, President of Bugatti In addition to the iconic 8.0 litre 16-cylinder engine with 1,500 PS, technical innovation is just as much part of our brand essence – such as our components made of titanium or a special alloy that are produced by 3D printing. Bugatti is in fact continuing a long-standing tradition here: the company founder Ettore Bugatti himself developed unique vehicles using groundbreaking technologies. His inventions include lightweight aluminium wheels and a hollow front axle.
As the only company in the automotive industry, Bugatti uses 3D printing to produce tailpipe trim covers made of titanium for its newly developed hyper sports car. The approximately 22-centimetre long, 48-centimetre wide and 13-centimetre high trim cover at the rear of the Chiron Pur Sport weighs just 1,85 kilograms including grille and bracket – some 1.2 kilograms less than the cover on the Chiron2.
“Wherever possible we designed the trim cover for the Chiron Pur Sport with a single layer so as to further reduce weight,” says Nils Weimann, Head of Body Development at Bugatti. The minimal material thickness in multi-layer areas is made possible by its so-called lattice structure – where the cavity is filled with numerous filigree struts. In this way, the walls provide stable support for each other during the construction process – enabling minimal use of material. We use a bionic honeycomb structure in the single-layer area to increase the surface rigidity of the walls. Even large components gain a high degree of surface stiffness, explains Weimann.
