The Digital Network

The Veyron’s*) central nervous system consists of three data buses –
one for the driveline, one for the convenience functions, and one for the internal diagnostics system. A total of 26 control devices is connected to these buses. This digital network comprises the car’s complete intelligence system: from engine regulation to electric windows; from rear spoiler control to GPS. In place of a traditional network, Bugatti equipped the Veyron with a lightweight onboard network also used in aviation technology. This saves 5 kg of weight and also offers extreme temperature resistance. The hub of this network is the telemetry computer. It constantly collects all vehicle data, checks them for reliability, and monitors battery voltage. As soon as the values become critical, the computer automatically transmits an error report to Bugatti – from anywhere in the world. Whenever there’s the possibility of a malfunction, there is also perfect service available. Customers may of course deactivate this option, but they can also intensify the service level: the Veyron’s GPS data are always accessible in case the car should go missing. In addition, the Veyron features speech-controlled, hands-free mobile phone operation with integrated Bluetooth technology. The Bluetooth GPS is controlled via an exclusive Bugatti PDA. Both systems use the Burmester sound system for crystal-clear audio output. All visual data are displayed on the rearview mirror – a feat made possible by the extremely bright LED display placed behind the semi-transparent mirror glass. The PDA boasts additional useful features: drivers can use it to access lap times, tire pressure, gas consumption, and key telemetry data.

The values were calculated using the prescribed measurement method (§ 2, numbers 5, 6, 6 per car energy labeling ordinance in its current version).CO2 emissions, which result from the production and provision of fuel or other energy sources are not taken into account in the determination of CO2 emissions pursuant to Directive 1999/94/EC. The figures do not refer to a specific vehicle and are not part of the offer, but only serve the purpose of comparing different vehicle types. The fuel consumption and CO2 emissions of a vehicle not only depend on the efficient utilization of the fuel by the vehicle, but also on driving style and other non-technical factors. CO2 is the main greenhouse gas responsible for global warming. Notice pursuant to Directive 1999/94/EC of each current valid version: For more information on official fuel consumption and the specific official CO2 emissions of new passenger cars can be acquired from the "Guide for Fuel Economy, CO2 Emissions and Power Consumption of New Passenger Cars" available at all sales outlets and at DAT German Automobil Treuhand GmbH, Hellmuth-Hirth-Strasse 1, D-73760 Ostfildern – available free of charge or at www.dat.de. Efficiency classes of vehicles are evaluated in terms of CO2 emissions by means of the vehicle's empty weight. Vehicles that correspond to the average are classified as D. Vehicles that are better are graded with A+, A, B or C. Vehicles that are worse than the average are given an E, F or G.
