Veyron and C7 Corvette join cast of Transformers 4

Like the Fast & Furious franchise, the Michael Bay-directed series of Transformers movies has become known as much for its bad acting as its impressive lineup of cars. As filming just started for Transformers 4, Bay's website has confirmed two new cars for the next installment as well as a makeover for everyone's favorite tractor trailer hero, Optimus Prime.
Joining the cast of T4 are a "race-inspired" Chevrolet Corvette Stingray and a Bugatti Veyron Grand Sport Vitesse. While Bay's website did not supply names for either car, Bugatti is reporting on its Facebook page that the Veyron will join the Autobots. Speaking of the good guys, top Autobot Optimus Prime is getting an all-new body based on a Western Star with a gaudy appearance that was seemingly inspired by Trick My Truck - right down to the six smoke stacks and side pipes!

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.

Xcar sends off the Bugatti Veyron

By now, there are a small but growing number of exotic supercars costing seven figures, producing 1,000 horsepower and reaching 250 miles per hour, but ten years ago, those kinds of bragging rights were unheard of. It was Bugatti that broke such barriers with the Veyron, and it's that story which Xcar tells in this latest video installment. The story of the Veyron is one of unprecedented technological achievement, the dawn of a new era of performance and the height of status-symbol transportation. It's also a story worth telling, and worth telling right. And we're glad Xcar has set about it. So sit back, crank the speakers and listen to the most cacophonic yet refined swan song in the history of the automobile. Related Video:
