The Veyron minus its interior and exterior components – the so-called “rolling chassis” – can be divided into three sections: the front end, the monocoque and the rear chassis.
The main components in the front end are all the air-to-liquid intercoolers, the starter battery, the luggage compartment, the front axle differential and the steering system. The front frame is the structural element of the front end, which houses all these components.
The monocoque section is built around the monocoque itself, which is the main structural element of this section. The main components of the monocoque section are the fuel system (albeit without filler necks), the accompanying fuel tank (installed in the rear of the monocoque), the crossbeam including the control panel, the steering column, the pedals with brake servos and master brake cylinder, and the air conditioning system.
The rear chassis section comprises the engine, gearbox and exhaust system, as well as the fuel system components: the engine and gear oil circuits, central hydraulics, filler necks and carbon canister.
The front axle is divided between the front end and monocoque sections. The front transverse link connections, stabiliser and steering gear are attached to the front end section. However, the rear transverse link connections and steering column are mounted on the monocoque section.
