Bugatti’s 8.0-liter quad-turbocharged W-16 is exclusive within the automotive world, powering the Veyron and Chiron to production-car velocity information. With the engine probably headed for extinction within the face of electrification, Bugatti not too long ago recounted its improvement.
The W-16 was the brainchild of former Volkswagen Group CEO Ferdinand Piëch. In line with the official story, whereas driving a Shinkansen high-speed practice between Tokyo and Nagoya, Japan, Piëch had some spare time on his fingers and sketched a large engine on the again of an envelope.
Piëch, who later retired simply previous to the VW diesel emissions scandal, envisioned a naturally aspirated 18-cylinder engine comprised of three VW VR6 blocks strung collectively, offset by 60 levels. It displaced 6.25 liters and was designed to provide 547 hp.
Piëch did not have a automotive in thoughts for this engine, however he later settled on Bugatti after his son Gregor requested for a model of a Kind 57 Atlantic. On the time, the rights to the Bugatti title had been up for grabs after a latest revival of the automaker by Italian businessman Romano Artioli (who produced the Bugatti EB 110) collapsed.
After engineers bought ahold of Piëch’s sketch, the design was modified to the quad-turbocharged W-16 configuration that finally reached manufacturing. The chief had set a objective of 1,000 metric horsepower, and this was thought-about one of the simplest ways to realize it.
The engine was first examined in 2001, and it introduced some distinctive challenges. A brand new take a look at bench and air flow system needed to be constructed to deal with the W-16’s energy output. Due to its smooth-running nature, a brand new system for detecting misfires and knocking needed to be developed, in accordance with Bugatti. The ensuing Bugatti Ion Present System (BIS) displays the ion present flowing at every spark plug.
The W-16 debuted within the Veyron 16.4 in 2005 with 987 hp (1,200 metric hp) and a 253.81 mph prime velocity, making it the quickest manufacturing automotive on this planet on the time. Bugatti then upped the ante with the 1,184-hp Veyron Tremendous Sport, which as soon as once more claimed the manufacturing automotive velocity file at 267 mph.
Veyron manufacturing resulted in 2015 to make method for the Chiron, which used a revised model of the W-16. For the Chiron, Bugatti launched sequential turbochargers, which helped improve output to 1,480 hp in preliminary variations (some subsequent fashions made much more energy). Whereas not a clean-sheet design, the Chiron model of the W-16 nonetheless obtained 16,000 hours of improvement time and greater than 310,000 take a look at miles.
As soon as once more, the W-16 would energy Bugatti to a production-car velocity file. In August 2019, a prototype Chiron Tremendous Sport 300+ hit 304.773 mph at VW’s Ehra Lessien take a look at monitor in Germany, turning into the primary manufacturing automotive to interrupt the 300-mph barrier. Bugatti only in the near past accomplished deliveries of buyer variations of the record-breaking automotive.
With Chiron manufacturing winding down, the W-16 will proceed in restricted editions just like the Centodieci and Bolide, which ought to maintain the manufacturing facility busy till 2025. After that, a Chiron successor can be produced underneath the stewardship of electrical supercar maker Rimac. Whereas that probably factors to an all-electric future, Rimac founder Mate Rimac, has stated the following Bugatti supercar can be a hybrid. However will it nonetheless have the W-16?
