Bugatti looks back at how how it developed the W16 engine

As the end of the Chiron's production run nears, Bugatti is taking a look back at the W16 engine that has powered its cars since it returned to the scene nearly 20 years ago. The engine is relatively compact, hugely powerful, and it has helped the firm set several world records. Former Volkswagen boss Ferdinand Karl Piech knew that successfully reviving Bugatti required building a car that stood out from everything else on the road at the time. He initially planned to power the then-upcoming Veyron with an 18-cylinder engine and sketched it out on an envelope while riding on a high-speed train from Tokyo to Osaka in Japan in 1997. His concept later became a 16-cylinder engine, but dropping a pair of cylinders didn't make the unit easier to develop. Bugatti engineers started from scratch in order to make the W16 a reality. "We had to engage in basic development for every component; every vehicle part had to be constructed anew and tested — even the engine test bench. The only thing we didn't change was the pencils we used for drawing," said former Bugatti head of technical development Gregor Gries. The initial goal was to launch the Veyron with over 1,000 horsepower, and even some insiders doubted that this could be achieved. Bugatti pulled it off: The Veyron entered production in 2005 with a quad-turbocharged, 8.0-liter W16 engine rated at 1,000 horsepower and 922 pound-feet of torque. Horsepower increased to 1,200 in the Veyron Super Sport, and the Chiron inaugurated a new version of the engine rated at 1,500 horsepower thanks in part to bigger turbos, though the Chiron Super Sport offers a 1,600-horsepower output. Engineers faced several significant challenges during the Veyron's development process. Getting the W16 to make 1,000 horsepower wasn't one; it broke the symbolic barrier the first time it was put on a test bench in 2001. Keeping its temperature in check required designing a massive cooling system that takes over 10 gallons of coolant and installing a titanium exhaust system. With the engine ready to go, Bugatti turned its attention to creating a car capable of coping with 1,000 horsepower, both in terms of comfort and in terms of aerodynamics. "Back then, there was no literature or empirical data for production engines with more than 12 cylinders or for production vehicles that could go faster than 217 mph," said Karl-Heinz Neumann, Volkswagen's former head of engine development.

Bugatti Chiron Pur Sport Review | It's the slowest but the quickest

Apparently, even some Bugatti owners consider the real-world ramifications of a $3.6-million, 1,500-horsepower car. The Chiron Pur Sport is proof. Somewhere, perhaps between the helipad and the superyacht, Bugatti prospects are realizing they’ll never have the opportunity or skill to reach 300 mph, or 261 mph — the respective top speeds of the Chiron Super Sport 300+ and standard Chiron. The Pur Sport squeezes a mere 217 mph from its own 8.0-liter, 16-cylinder, quad-turbo engine. But Bugatti says the Pur Sport is the quickest Chiron at any speed between zero and 217 mph. ItÂ’s also the lightest, sharpest-cornering, least-insulated version — optimized for a driverÂ’s sensory stimulation, versus the largely psychological bragging rights of top speed. Consider it the high-performance version of one of historyÂ’s highest-performing cars. After driving the Pur Sport in Connecticut, with three-time 24 Hours of Daytona-winner Butch Leitzinger riding shotgun, IÂ’ll say itÂ’s definitely the one you want. “You” here would refer to Powerball winners, a payback-minded Melinda Gates, or silver-spooners who scoop up one of 60 Pur Sports, among 500 Chirons scheduled for production through about 2023. Leitzinger explains how it all works, as we walk around a Pur Sport in striking Atlantic Blue paint. Tasteful copper trim adorns the BugattiÂ’s signature C-shaped line that shelters doors ahead of the side inlets for turbo air and their intercooler radiators. Front wheel-arch vents extract more air. Less-tasteful is the optional number "16" emblazoned on the Pur SportÂ’s widened horseshoe grille, as if anyone could forget the unsurpassed cylinder count. Ditto for giant "Bugatti" lettering on the Pur SportÂ’s angled, 74-inch-wide rear wing. Add a Bugatti pillow, and it could double as a sunbathing deck. (As with everything Bugatti, the jersey number and lettering are entirely a matter of choice.) The fixed wing is tasked solely with downforce, replacing the electro-hydraulic wing/air-brake on other Chirons that adjusts to trim drag for record-setting acceleration runs. Its stanchion and a massive diffuser form a cool X-shape, atop an artfully thin-walled, 3D-printed titanium exhaust, its temperature-resistant outlets seemingly large enough to service a nuclear reactor. The view-blocking wing saves 22 pounds, among 110 pounds of total weight savings versus a Chiron.
