US Markets Loading H M S In the news. Travis Okulski. The cylinder engine is the heart of the Veyron. And it's journey starts here: VW's Salzgitter engine plant. This is, without a doubt, one of the largest engine factories in the world. Yet the Veyron's engine is assembled by hand in a tiny room. The bespoke titanium and aluminum parts are delivered by hand in sealed, padded cases. Each piston is carved out of solid aluminum. The engine is actually a W configuration.
This is two V8 engines bolted together. It takes craftsmen one week to complete a single Veyron engine.
To test it, they ran it on a dyno for the first time in There, it produced the magical horsepower, and then some. The building almost burned to the ground. When the car was first tested on the road, it had 6 foot flames shooting out the back at MPH.
That isn't exactly legal. So they upped the cooling capacity. Each Veyron has 10 radiators. Italian company Riccardo was contracted to make the gearbox. While it is common now, this was one of the earlier applications of a dual-clutch unit. They could make it go, but could they make it stop? The Veyron has massive carbon-ceramic brakes. They are all hand made, once again in Germany. They can withstand heat up to 1, degrees farenheit. But that wasn't enough to safely stop the car.
Designers and technicians worked together to harmoniously integrate all functions in the cockpit, giving the Veyron the unique atmosphere and quality of a Bugatti. It is the first — and the only — supercar to be developed and constructed with a series configuration that can master any driving scenario at any time.
While other supercars need to be specially prepared for the relevant scenario beforehand, the Veyron rapidly configures itself accordingly without the driver needing to do anything.
Maximum acceleration on long straights, winding country roads or urban traffic — the Veyron is always perfectly configured and extremely comfortable to drive.
The heart and soul of the Veyron is the 8. The cylinder mid-engine is mm in length, no longer than a conventional V12 engine, and weighs just kg due to its lightweight construction. The engine is fully capable of operating under a continuous full load, a feat that engines designed for use in motor racing, for example, cannot achieve.
Its compact dimensions are due to the unique arrangement of its cylinder banks in a W configuration. Two VR8 blocks, each with a degree bank angle, are joined in the crankcase to form one engine. Both eight-cylinder blocks are set at an angle of 90 degrees to each other and are aspirated by a total of four exhaust gas turbochargers.
The Veyron is equipped with a 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 road car gearbox would balk at: to transfer engine torque of up to 1, Nm to the road surface. At the time, the direct-shift gearbox used in the Veyron was a uniquely perfect combination of the dynamic advantages of a manual gearbox with the convenience of an automatic transmission.
When it was developed, no other manufacturer had comparable technology. In a high-performance vehicle such as the Veyron, it is essential that the engine is always supplied with constant fuel pressure. The fuel tank also had to be redesigned. Bugatti turned to the world of motorsport, but had to rebuild the conventional fuel tank used in racing, which is not permitted for road vehicles, to ensure that it would be approved.
Bugatti consulted engineers in the aerospace industry, and the outcome was a fuel tank with an external Teflon coating which provides the fuel pumps with a constant supply of fuel in every situation, up to a residual capacity of three liters and maximum lateral acceleration of 1. Cooling is an extremely important aspect of the Veyron.
During combustion, some 2, PS of additional heat is generated for 1, PS of drive power. To cope with this, the Bugatti engine has two water circuits. The larger circuit contains 40 liters of coolant water in three radiators in the front section of the vehicle to keep the engine at operating temperature.
The second, a low-temperature circuit with a separate water pump, contains 20 liters of coolant water. A car to really showcase the engineering might of the VW Group. There began a series of concept cars, displayed in quick succession, and all fitted with that 6. Then we saw the EB four-door saloon — an update of the EB Old Bugatti displayed and almost put into production in Skip 8 photos in the image carousel and continue reading Turn on Javascript to see all the available pictures.
It would also be no less usable than a Golf. Remember at this point, no Veyron prototype had yet run. This was a tall order. The tallest of orders, in fact. Sure enough the Veyron took years and vast sums of money to develop.
Though the W18 lost a couple of cylinders along the way, the engine was apparently one of the less, erm, 'challenging' parts of the project. Everything else gave the engineers massive headaches, from the double-clutch gearbox that had to work in car parks just as well as it did at mph, to the tyres and aero.
