See a 700-hp Hennessey Corvette Stingray hit 200 mph on a Texas toll road

It takes a Texas-sized ambition — some might say ego — to grab the world's hottest sports cars, tinker with their innards and then plaster your name across the windshield. Fortunately for John Hennessey, that tinkering often produces a car that's wilder and wickedly more powerful, so much so that when Hennessey wanted to get his twin-turbo Cadillac CTS-V up to 220 mph, he had to borrow an unopened stretch of new Texas toll road.

Last week, Hennessey and the Texas state troopers were back at it — this time with a 2014 Chevrolet Corvette Stingray bumped up to 700 hp, proving once again that the Lone Star State can properly track cars traveling 200 mph.
