In what he claims is a first-ever trip to 200mph by a tuned C7, JH tests the Ez-Tag system by blowing past it at more than double the already-enthusiastic 80mph toll-road speed limit. Interestingly enough, the factory speedometer in the LCD display appears to be dead-on accurate.
The road is smooth as silk, easy-breezy, Hennessey indicates, in a phrase that will no doubt launch at least a dozen imitators.

Looks like fun to me!
Can you see a turtle or armadillo at 200MPH
“Interestingly enough, the factory speedometer in the LCD display appears to be dead-on accurate. “
The above say something about peoples expectations; geeez, in this day of electronic and microchip advancement speedometers OUGHT to be dead on.
Never mind the small critters, watch out for the hogs and deer.
Between GPS and wheels speeds, vehicular speed instrument accuracy should be better than one percent at speeds above 10 mph.
Pink mist in your rear view.
Noted the campaign commercial at the vid end for Dewhurst.
A turkey will also do a number on a car. But at least you’ll live have a bird for the table.
I’ve been on that toll road. Speed limit is 85 mph. I can do 90 easily in my 8 year old Xterra. It is indeed an awesome road.
If that C7 is only doing 200; I wonder why they held back?
Not enough power to break 200, maybe?
” bird for the table.”? Won’t be anything much to eat... don’t ask how I know! HA
Reminds me of my youth! Thanks! Over 120 before LED was plenty fun enough.. Needed another gear 8-!
The driver was wearing a helmet, but at 200 MPH, he isn't wearing a helmet, the helmet is wearing him. </Seinfeld>
I suspect there may be an electronic governor on the speed. I read where 195 is the top speed.
But do a little tweaking and - - who knows how fast it’ll go?
Note that he got the last few MPH out of it on the downhill side.
That being said, 200 MPH is an awesome accomplishment in any car.
Regardless of circumstance I’m impressed at the stability of the car, largely factory spec, at 200 mph. I’ve taken cars to 140 mph before and it gets a little spooky, to be quite honest, minor imperfections in the pavement set the suspension off, I really don’t like any hint of instability at such speeds. So, this is impressive, as I mentioned.
Took a little while to get that last 5 mph didn’t it, lol?
That’s the original concept for the C7? Much nicer lines. The rear of the factory model is too Camaro, and they’ve lost any hint of the coke-bottle shape that has been a Vette trademark since the sixties. That concept still has it.
I remember at the GM Proving Ground a test car hit a duck at about 120 mph and it smashed the carburetor.
Yes, aerodynamics is everything. Low ground clearance, fins, balance, smooth road. You want negative pressure under the car.
Immpressive for a non super car, but this is foolish driving outside a race track.
Never happen in a Stingray.
~~~the helmet is wearing him. </Seinfeld>~~~
on a Texas road?
Try to find a road there without one or the other
The Great Armadillo of Texas,, And lone Star
I’m so old school I remember when the Lamborghini Countach was desperate to break it, but couldn’t. I stopped following the issue around that time.
Apparently it became a non issue since then. :-)
I suppose. I'm not sure. But I saw not long ago some new Corvette or possibly concept model that had tail lights very similar to that of the new Camaro, which I don't care for at all. They were rectangular, as opposed to the traditional 4 little circular tail lights.
I used to go over 200 in my vehicle.
A Cessna T210 with 285 HP cruise.
Just don’t make a mess of your screen and keyboard. Lol.
The concept utilized a rear section from the doors back that draws very much from the original split window Stingray coupe, even the center rear section, with the four circular shapes of the taillamps transferred to the exhaust, and sort of implied “outrigger” blade fenders with heavy aero effects and brake ventilation. Factory lost all of that, maybe a hint of a few shapes, nonfunctional.
I had my brother’s Dodge Conquest at 142 once... and it felt like the front wheels were off the ground. Everything was floaty and surreal.
Scared me into obeying posted limits.
well, at least it will be tender....
I go over 66,000 MPH on my bicycle. That is, the Earth goes that speed in its orbit round the Sun. That's 18 miles per second.
I grew up just down the hill from the GM proving grounds in Milford. My buddy and I took his 72 Charger with a built 440 down that hill wide open one day, didn’t know how fast we were going but we hit a sparrow Just before Spencer Rd where the hill starts to flatten out.
We actually felt the thump pretty good for a small bird, then about 1 second later a small puff of tiny feathers came through his vents, he almost wrecked it when he started laughing hard.
It’s a wonder we ever lived to see 21...
I rented a HERTZ Yellow and Black Corvette a few years ago after flying into Tampa. I had it up to 140 twice on I-75 south of Tampa and it was plenty fast. I had been about 125 (speedo only registered 120) in my 1975 Ranchero GT back when I was 17 and that didn’t phase me too much but the extra 20 MPH in the ‘Vette (sitting so low to the ground you feel as though you are going even faster), combined with rapidly catching up with traffic and not familiar with the types of cop cars and where they hide on I-75 got my heart racing pretty good. Had I been on my home turf I would have tried for a little more.
I wouldn’t be surprised if the speed limiter is disabled on this particular car. I saw another article about this on Jalopnik and apparently Hennessey has worked a little magic on it...
Plenty of modern cars, even fairly modest sedans, are predictable and stable up to around a hundred. Go beyond that and the number of predictable and stable cars falls off pretty rapidly. Not very many are drivable at all at 150 even if they could reach that speed. 200 is impressive for a largely factory spec car from any manufacturer.
Well, with the SLOWEST Bugatti Veyron capable of around 240mph, I guess 200 isn’t such a big deal anymore...
And I remember back in the ‘70s Lamborghini claimed 195mph for the Countach, but nobody ever got one up to that mark. At least not a stock one.
I’m not sure if that applies to my 57 Bel Air.
I’ve had it up to 80. Feels like 200. :)
Frankly, for 200 mph I’d want a REALLY long wheelbase.
Lotta aero improvements in the last 50 yrs LOL.
And a Veyron costs what, lol?
Yeah but for 1.3m USD how hard can it be?
I have seen triple-digit speeds in three different cars. The first was a ‘76 Mercury Grand Marquis, which I got to 110mph (indicated) back when I was in high school. 5,000 pounds of American iron on soft springs and dead shocks at that speed is pretty darn spooky.
The next was a 1985 Nissan 300ZX, in which I once saw 115mph. Once it got above that speed the front end started getting light but it was not nearly as scary as the Mercury was.
And the third was my current car, a ‘91 Miata. I’ve seen 115 in that car as well, and that is absolutely all she has to give. But she’s very well-behaved at that speed, even as light and stubby as a Miata is.
Don’t take that to mean I want to see how stable she is if I give her sufficent power to top out at 200, though!
