The Bugatti Chiron presented here is a so-called data control model (DCM). This development stage, which is usually not shown to the public, marks an important point in the vehicle design process.
Based on sketches and digital models, a total of three hard models are made from laminates. After the vehicle proportions are validated on the first model, the second model is used to specifically check the surface dynamics, highlights and reflections as well as the surface tension of the concave and convex body elements. Details, including mirrors, door handles, exhaust system, headlights and wheels are also discussed and coordinated. For the Chiron, a key ergonomic decision was taken in this phase to extend the rear door panel into the sill area to facilitate entry. The third hard model following this phase marks the design freeze and hardly differs from the production vehicle.
Bugatti Chiron: Fuel consumption, l/100km: 35.2 in urban areas / 15.2 in extra urban areas / 22.5 combined; combined CO2 emissions g/km: 516; efficiency class: G
Fuel consumption, CO2 emission figures and efficiency classes given in ranges depend on the tire/wheel sets used.
More information about official fuel consumption figures and official specific CO2 emissions of new motor vehicles is available in the ‘Guidelines on fuel consumption, CO2 emissions and electric power consumption of new motor vehicles’ which are available free from all retail outlets and from DAT Deutsche Automobil Treuhand GmbH, Helmuth-Hirth-Str. 1, 73760 Ostfildern-Scharnhausen, Germany (www.dat.de).
The fuel consumption and CO2 emissions of a motor vehicle, and deviations from the stated values, depend not only on the efficient use of fuel by the vehicle and other factors (e.g. the choice of wheels and tyres), but are also influenced by driving style and other non-technical factors.
