With a toll road all to itself, Hennessey pushes its HPE600 Corvette Stingray past 200 mph

The stock 2014 Chevrolet Corvette Stingray is a very nice car, but can it go 200 mph?

Hennessey Performance Engineering is never satisfied with stock, which is why less than a year after the C7 Corvette’s debut, the Texas tuner has pushed one past the double-century mark.

As with many of Hennessey’s high-speed shenanigans, the HPE600 Corvette stretched its legs on a closed section of Texas State Highway 99. That’s the brand-new toll road with an 85 mph speed limit, by the way.

The ‘Vette achieved 200.6 mph, as recorded by the highway’s RFID toll system. Clearly, toll dodging on this road is not a good idea.

The HPE600 package upgrades the 6.2-liter LT1 V8 with ported cylinder heads, a new camshaft, and retuned software. There’s also a freer-flowing exhaust system and the Texas test car had a 100-shot nitrous-oxide system from Nitrous Express just for good measure.

The result is a staggering 700 horsepower, compared to 460 hp for the stock Stingray. Hennessey said the increase in power was necessary, even though 200 mph is only about 20 mph faster than the stock car’s top speed. At high velocity, aerodynamic drag becomes a major issue.

If you saw The Fast and the Furious and think nitrous is just an invitation to have your car consumed in a ball of green flame, Hennessey also plans to offer an HPE700 upgrade package with a supercharger, which the company says will reliably get a Stingray past 200 mph.

If you want your barnstorming bow tie to have four doors, Hennessey also offers an HPE600 Chevrolet SS. It’s already achieved 164.2 mph, although Hennessey says it will go faster with better gearing.

The Onn. Dual Dash Cam, installed in a vehicle.

Mercedes-Benz G580 vs Rivian R1S: rugged electric SUVs, compared
Range of Mercedes-Benz G580 vehicles

Mercedes-Benz has finally unveiled the long-rumored and heavily teased electric G-Wagon. The new vehicle, officiallydubbed the "G580 with EQ Technology," retains the beloved design of the G-Wagon, but with an interior refresh and, more importantly, an all-electric powertrain. But the vehicle goes up against tough competition -- especially in the rugged electric SUV space. Perhaps the most-loved electric SUV so far is the Rivian R1S, a three-row SUV from a new startup that, for many, is the go-to option above a certain price range.

Now, of course, there are some big differences between the two vehicles. But is one better than the other? Here's a look at the Mercedes-Benz G580 and the Rivian R1S, head-to-head.
Design
The designs of these two vehicles is radically different, but they do have some similarities. They're both boxy and square, and are high enough off the ground to allow for some off-roading.
