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 Burmerster 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 lightweight electrical system of the Veyron (below) weighs much less than a conventional on-board system and is also more temperature resistant.
