Advanced details of how the Bugatti Veyron W16 engine works in 3D
we analyze the most colossal engine of all engines.
Bugatti's W16.4. An engine whose numbers are all small.
thanks to this feature, discover the three configurations of the bugatti veyron using the example of the high speed sport. with a top speed of 410 km/h, it is the fastest production roadster ever built. to guarantee optimum use at such a high level of performance, for each speed, the super sports car needs a balance between lift and downforce.
The 8.0-litre W16 engine has been powering Bugatti hyper sports cars for nearly 20 years. The only 16-cylinder engine in the world to be used for a production vehicle, this absolutely unique masterpiece of engineering quickly became a true icon. This retrospective dedicated to its history – from its creation to its evolution – can be seen as a declaration of love for one of the most impressive engines ever created.
16 cylinders, 8 litres, 1001 HP. By announcing, in 2005, the characteristics of the engine of its Veyron 16.4, the Bugatti brand entered a new dimension. It changed the game in a sensational way by offering, for the very first time, a production vehicle equipped with an extremely powerful and yet very compact engine, allowing extraordinary handling while achieving record acceleration. The performance was unparalleled at the time: 2.5 seconds was enough to go from 0 to 100 km/h with a top speed of over 400 km/h. By launching the production of the Veyron 16.4, Bugatti is a true pioneer and is writing a new page in automotive history by creating a whole new category of cars. The Veyron becomes the first “hypersportive”. And all this would not have been possible without the W16 engine.
In March 2016, Bugatti presented the successor to the Veyron: the Chiron. Once again, the brand achieved what was then thought impossible by surpassing the power levels of the Veyron – which themselves already seemed unattainable at the time – by 50%. Yes, just like the Veyron, the Chiron has the famous 8-litre W16 engine and four compressors, but to reach such new levels of performance, the brand had to redesign every component. To compensate for the increase in weight due to the increase in power, the manufacturer used lighter materials - such as titanium and carbon - but what really made the difference on this new model were more powerful turbochargers. and a duplex fuel injection system with 32 valves. With an initial output of 1500 HP, later increased to 1600 HP, and a maximum torque of 1600 Nm, the W16 engine once again changed the course of history when it comes to automotive performance.
THE GENESIS OF THE W16 ENGINE
The road was long. In 1997, the great engineer Ferdinand Karl Piëch, at the time Chairman of the Board of Directors of Volkswagen AG, presented Karl-Heinz Neumann, Head of Engine Development at VW, with his very first idea for the W16 by drawing it on a simple envelope while traveling by Shinkansen between Tokyo and Osaka. His initial idea – an engine made up of 18 cylinders – was later modified to give birth to the W16 that we know today. A strong tribute to the 16-cylinder engine developed by Ettore Bugatti himself.
From an idea by Ferdinand Piëch sketched on an envelope, the engineers developed an 8.0-litre W16 engine. The 16-cylinder mid-engine, no larger than a V12 and weighing only around 400 kg, owes its size to the unique “W” shaped cylinder arrangement. Two blocks of eight cylinders form an angle of 90 degrees to each other and are ventilated by four turbochargers. The challenges that Karl-Heinz Neumann and his team had to overcome
THE DEVELOPMENT OF THE W16 ENGINE
To give life to this engine, 3500 parts were assembled by hand under the supervision of a control computer. During the first test in 2001, the twin-turbo engine immediately delivered 1001 HP – theory and practice could not have been better matched. However, the engine test bed and the ventilation system pose a problem: they are not designed for such power and will have to be reworked for the W16 engine. In addition, new requirements – which hitherto did not apply to production vehicles – have been added, such as the need to channel very hot exhaust gases. The team will finally opt for a titanium exhaust system of a dimension never seen in the automotive sector.
Once the desired performance had been achieved, the engineers turned their attention to the reliability of the vehicle. As the 16 cylinders provide a naturally smooth engine operation, detecting a misfire or knock in the engine by traditional methods would not have been reliable. Bugatti has therefore developed the “Bugatti Ion Current Sensing” (BIS) system to monitor the ion current flowing through each spark plug. If the system detects knocking combustion or a misfire, the ignition timing is reduced, the cylinder deactivated or the boost pressure reduced. Each cylinder can thus be pushed to its maximum performance. “From the start, our goal was to generate maximum engine performance, in a stable and clean manner. »,
The cooling system too was absolutely crucial to the reliability of the W16 engine and – as you might expect – it was designed on a scale never before seen in the automotive industry. A complex cooling system with two water circuits keeps the W16 at the required temperature, even under full load. During the high temperature cycle, 40 liters of water circulate through the three front coolers. The low-temperature circuit with separate water pump holds 15 liters of water and cools the heated turbocharger charge air by up to 130 degrees in two heat exchangers on the engine. There are also coolers for differential oil, gearbox oil, engine oil and heat exchanger for air conditioning. The W16 is integrated into the Veyron as a longitudinal mid-engine with a seven-speed dual-clutch gearbox located at the front of the engine.
Traditionally, turbochargers are added to increase power in small engines. At Bugatti, the basic engine already has a lot of power, but the four turbochargers provide extremely powerful additional propulsion to create something truly incomparable. “To hit the road with the W16 is to experience a feeling of limitless, almost infinite power and performance. Whatever speed you've already reached, whatever the situation, the engine always has something underfoot to allow you to accelerate further. When going from cruising speed to fast driving in seconds, the W16 remains smooth and stable. It is this absence of limits that seduces our customers. explains Pierre-Henri Raphanel, Official Bugatti Driver, who has covered more than 100,000 km at the wheel of the Veyron and the Chiron.
“With the Veyron 16.4 engine, Bugatti showed – even before series production – that only an exceptional team could make this concept a reality. It is only thanks to the incredible commitment of our employees that this exceptional engine has been improved, redesigned and perfected over the past few years. », enthuses Christophe Piochon, President of Bugatti Automobiles, evoking the indefatigable will of the mark not to give up. This unique engine is the embodiment of Ettore Bugatti's motto: “If it's comparable, it's no longer Bugatti”.
