The active surface area of the catalytic converters is massive. It has the longest light conductor ever fitted to a car. It has the biggest clutch ever fitted to a passenger car. It's as rigid as an LMP1 racing car.
Very few parts, components or systems from existing vehicle concepts could be used in the Veyron. Everything had to be developed from scratch to achieve the required performance before being incorporated into the vehicle. When creating the Veyron, designers regularly drew inspiration from other industries which required extreme speeds and demanded extreme stress loads from materials and systems.
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, stabilizer 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. The Veyron has a carbon fiber monocoque with a prepreg design. The monocoque has a sandwich structure with an aluminum honeycomb core encased on both sides by sheets of carbon fiber.
The main function of the front end structure, apart from housing numerous vehicle components, is to provide outstanding crash properties. Since it is virtually impossible for the monocoque to deform in case of a crash, all the crash energy dissipates in the front end. This ensures constant optimum safety for Veyron drivers and passengers: a front end that is deliberately designed to be deformable thanks to extruded aluminum multi-chamber profiles, combined with a virtually undeformable passenger compartment.
The aim of the rear carbon fiber structure is to maintain the extremely high torsion rigidity of the monocoque in full right through to the point where the rear suspension struts are connected. This is the only way to perfectly interlock the sections of the chassis and achieve outstanding lateral and longitudinal dynamics in all driving situations. Because it has two carbon fiber longitudinal members, which was unique at the time it was made, it is able to do this even without the usual transversal-bracing over the engine, which opens the W16 engine to view and further optimizes the venting of the engine compartment.
Optimum crash properties are also required in the rear of the car. Accordingly, highly deformable extruded aluminum multi-chamber profiles are installed in the area behind the exhaust system. Due to the turbochargers and exhaust system, extremely high rigidity is required in a very hot environment in the lower area of the rear chassis. For this reason, extremely strong, aviation-grade stainless steel was chosen for the two triangular longitudinal frames and the box-shaped rear axle carriage frame.
The heart and soul of the Veyron is the 8-liter W16 engine with four turbochargers, which initially generated 1, PS, and an incredible 1, PS in later models. The engine is fully capable of operating under a continuous full load, a feat that engines designed for use in motor racing cannot achieve.
These scoops direct a flow of air into the two air filters, each of which supplies two turbochargers. The air end on each turbocharger compresses the air before feeding it through the two intercoolers and throttle valves into the two inlet manifolds. The exhaust gases, in turn, power the four turbochargers and pass through the catalyzers into the liter titanium exhaust system.
From there, the exhaust gas is vented out into the open air through four tailpipes — two visible on the vehicle tail and two concealed in the rear diffusor. The Bugatti Veyron engine is designed in a so-called W configuration.
Unlike other W engines made by Volkswagen, it has a 90 degree bank angle. Each bank has eight cylinders in a VR arrangement, ensuring optimum use of the available space. The crankshaft has eight large-end bearing sockets, with two large-end bearings per socket. In contrast to the usual positioning of auxiliary units on the engine, with the W16 engine they are positioned in a separate ancillary system holder behind the engine.
This makes optimum use of the available space and protects the ancillary systems from excessive heat from the turbochargers and catalyzers. Each cylinder has four valves: two supply it with inlet air and two more vent out exhaust gases.
Four chain-driven overhead camshafts operate the valves of which there are 64 in total. The Veyron is equipped with the dual-clutch gearbox DSG , which is the fastest gearbox in the world. Bugatti was the first manufacturer to use a seven-speed variant of the DSG. Designed specially for the new sports car, this gearbox has a job which any other gearbox would balk at, i.
The seven-speed dual-clutch gearbox comprises two clutches with four gears each: one for the even and reverse gears, and the other for the odd gears. The actuator block, which controls the clutches and valves, is located between the two clutches.
The downforce is transmitted to the rear axle along the right-hand side relative to the direction of travel. The shaft runs from here to the rear axle differential between the turbochargers and engine block. The downforce is transmitted to the cardan shaft, and hence the front axle, via the front end of the gearbox.
The even and reverse gears are located in the front section of the gearbox housing and are connected to the dual clutch via a long shaft. The gears 1, 3, 5 and 7 are located in the rear section of the gearbox housing. So it is the only place where you can remove the wheel from Veyron. The rear wheels are Although the car could be made to go faster, the rationale was, that if you started with a full tank of fuel and accelerated to the top speed, the tires would disintegrate before the fuel ran out.
Furthermore, the Veyron actually decelerates from 60 mph faster than it accelerates to that speed. It also manages to scrub off its top speed in an astonishing 9.
