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 Galibier to be "faster than anything on the market"

Before Wolfgang Dürheimer moves to Audi, he's still got a few jobs to finish as head of Bentley and Bugatti, one of them being to oversee the development of the 16C Galibier. It was back in 2009 that the two-tone concept had audiences agog, and rumors and leaks since then have had everyone wondering if the four-seat fastback will ever become reality. To hit 'rewind' on the rumormill, the Galibier was initially greenlit in early 2011 and tipped to go into production this year, a timeframe that was later revised to next year. The model was earmarked to have less than 1,000 horsepower and optional hybrid power, and at the same time, the design was meant to be finalized, but it was instead reportedly scrapped for not being outrageous enough. The Galibier then went back to the design bureau and the horsepower was subsequently announced as surpassing the four-digit mark.
Production is now planned for somewhere around 2015, and according to Dürheimer's chat with Car and Driver, the Galibier on the way will be original and blindingly fast. The executive would only commit to the "over 1,000 hp" line, but C/D believes the ouput will be around 1,400 non-hybridized ponies. Whatever the final number is, it is said to get the Galibier beyond 235 mph and, Durheimer said, be "faster than anything on the market" - and that includes wares from the aftermarket sector. Dürheimer also says the Galibier will have technologies that are automotive firsts.
What remains to be decided is the candy coating that will envelop all that sweetness, since "the final design still is in flux." We'd heard before that the hatchback's entire rear end is being redesigned, but it appears that if nothing else, the eight tailpipes will remain.

Kawasaki H2R races Bugatti Veyron, MP4-12C, and 1,350-hp GT-R

The Kawasaki Ninja H2R ranks among the modern marvels of the production motorcycle world. The bike is only for the track, but with a 1.0-liter, supercharged, four-cylinder engine making 300 horsepower, it's ludicrously quick. Super Street decided to put that acceleration to the test by staging a half-mile race against a Bugatti Veyron with the 1,200-hp tune from the Super Sport. We aren't going to spoil the winner, but according to Super Street this bike is the only H2R that Kawasaki USA currently has. The magazine also staged similar races against a McLaren MP4-12C and a Nissan GT-R with a claimed 1,350 hp, and you can check them both out below. If you're curious to read more about this event, there's an in-depth piece online about it all, as well.
