What makes the Chiron Sport different is the fact that it's been on a diet. That's resulted in a weight loss of 18kg. Most of that shedding is courtesy the increased use of carbon fibre for components such as the stabiliser, and the intercooler cover. And, Bugatti has gone to crazy lengths to ensure weight is kept at a bare minimum. For instance, the windscreen wipers have been 3D printed in carbon fibre. That, Bugatti claims makes it 77 per cent lighter (1.4kg) than the one on the regular Chiron. The rear window is made out of lighter glass, and the exhaust deflector has helped shed some weight as well.
