The aftermarket specialists from Hennessey recently took their modified 2014 Corvette Stingray to test its top speed on the Texas State Highway 99. The segment of highway was just finished and it was closed for the public. The Hennessey Corvette Stingray managed to hit a top speed of 200.6 mph (just over 320 km/h). Hennessey is able to modify your 2014 Chevrolet Corvette Stingray to develop as much as 1,000 hp. However, the Corvette Stingray used for this top speed run develops "just" 700 hp.
