We knew that once Hennessey Performance got its hands on the seventh-generation (C7) Chevrolet Corvette Stingray, big things were going to happen. Well, a 200.6 mph (322.8 km/h) run on a closed section of Texas' brand-new State Highway 99, was just a shade bigger than what we were expecting. The run was also a test of the new toll road - which Hennessey founder John Hennessey called "perfectly smooth" - and the RFID toll system, which was still able to tag the Corvette at said 200 mph / 322 km/h (toll dodgers beware!). The blistering run was, naturally, caught on video, which we've included here at the bottom of the page.
The car you see here is fitted with what Hennessey calls the HPE600 package, and includes long-tube headers, ported cylinder heads, high-flow catalytic converters, and an HPE camshaft and engine tune. There's also a 100-shot of nitrous oxide available from a Nitrous Express kit, just for that little extra bit of punch. The result is 700 horsepower, up from the standard Stingray's 460 ponies.
If you're still scoping out that list of modifications and are wondering why the word "supercharger" doesn't appear, then take solace in the fact that Hennessey will deliver a blown Stingray, which it claims can crack 200 mph (322 km/h) without the laughing gas. Called the HPE700, it adds a TVS2300 supercharger and new induction system to the list of goodies found on the HPE600, and will cost US$22,500.
We have the entire video of the high speed run down below, along with photos and videos of the epic run.
