Hennessey has a proud history of tuning high-performance machinery from General Motors and taxing it out onto Grand Parkway, a new stretch of toll road on the outskirts of Houston, Texas. That's what it did with the Cadillac CTS-V, spooling its twin turbochargers until it cracked 220 miles per hour. It did the same with the Corvette Stingray, feeding it nitrous all the way up to 200 mph. Now it's time for the new Chevy SS.

Fitted with its HPE600 Supercharger upgrade, Hennessey took the Bowtie muscle sedan out onto the closed-off section of Texas toll road to help state officials test out their new TxTag system and ran it all the way to 163 mph. Is that all, you ask? Hennessey points out that, even with the modifications, Chevy will only allow the SS to run to its top speed in the fifth of the six gears available. So while it might very well be capable of going a lot faster, until someone figures out a way of deactivating that speed limiter, 163 will be its V-max. Check out the footage below.

        The Gvmnt will never give that kind of choice...might as well right that off. :) And I agree on the styling, typical Holden/GM parts bin model with a nice big MSRP and marketing to push'em.

          idiots, I know it is not based on a Malibu - I sell GMs so dont think I am biased against them. I was referring to the styling, which is woefully neutered. Therefore, since I sell GMs, I also have been in a Cruze...many times. This interior looks the same. Granted, I have not been in a SS, but it looks just as cheap...I guess it might be one of those better in the flesh kind of things. Still, a disappointment all over the place. It looks like a puffed up Malibu. Who cares if it is RWD and has a V8. It looks vanilla, and is way too much money for what you get. Go buy a Pontiac G8 GXP, and have ball modifying it with the money saved...and it comes in a manual.

          with all that power, I would like the choice at least. Also, that interior looks like a 20k car, not a 50k car. Straight from a Cruze. My main complaint is about the styling, and lack of a manual. Both are major letdowns IMHO.

        It is not based on the Malibu (which is FWD). This is RWD, based upon the Holden Commodore platform.

        GM Superior? Not quite, but maybe with a little more of our taxpayer dollars thrown at them, they might be 8/10 of Ford. Ford is the only one right now innovating and giving people cars they want and will buy. GM is right back to their old tricks, making washed up models out of other models, with interior quality on par with 1985 and putting overblown MSRP's on them. I'm sorry but $56k for a ZL1 Camaro is thievery no matter how you slice it. GM is once again proving they have no idea what they are doing. And Ford happens to have this model called the Mustang Shelby GT500 that has a top speed of 202mph...but again...pointless.

          It won't make more power the longer you run it. This isn't a video game. When it stops accelerating, its done. No more no matter how 'hard you push it'.

          I've had more high powered cars on a track than you will ever drive in your video game. Its called top speed for a reason - the top speed the car will go. Why don't cars go 1200MPH on Bonneville then? Those guys are wide open for miles and miles, no one is scared there. Why don't the cars just keep accelerating? Oh yea, because its not a game kid.

        "do you know how stupid you look right now" No, please tell us how stupid we look... You brag about "breaking the law" on the internet. You say you have videos with 3 angles of it, so please post the links. You have horrible English and grammar, so I know no one would ever hire you for a job in which you could actually afford any of the cars you claim to have driven. You call people "poo pushers." (What the hell is that? The new 5th grade insult?) Kid, drop the act. We know you are at most 13 years old and the fastest you've ever traveled was in GT5. And I'm done talking to the troll. You'll just have some idiotic response with a lot of hahahaha's and poo pusher comments.

      How much did Hennessey pay the state to close down this Public road to do this "original" idea? Sorry paying public, someone else wants to use it that's got deeper pockets.

          Hardly trolling. Is that the standard response when someone says something you disagree with, or goes against your views or opinions? Like I said, there is nothing more I need to read in that article but the title. Not everyone likes GM or Hennessey and we have a right to our opinion and just as much right to express it on an open public forum. If you don't like my comments, don't read them. And if you think GM is NOT poorly built, you must have never owned one or you have a strange definition for "poorly built". They have been behind in quality for 40 years! And false information doesn't apply because it's my opinion. It's not false to me and many others in the world (and in fact more truth than opinion). I have said nothing that made me look stupid. You on the other hand have nothing more intelligent to add than call people trolls who disagree with you. Maybe you should go back to your "High quality built" Chevy Cobalt forum and hunt trolls and leave the real intelligent commenting to the big boys.

          What's to know...a well known tuner, takes a poorly built GM car out to a closed course, to see how fast the pointless crazy HP can take it. I can get everything I need right out of the title of the article, and the first word in the first sentence. No need even watching the video.

        Hennessey didn't pay anything to close it down. The road was closed because it wasn't fully finished. The company's reputation did probably allow them to get permission by the state to test on the road to see if their e-pass toll system works on cars that try to speed through. Seems like a good idea to me and a valid reason for the tolls to be tested.

      What is the big deal with top speed when you have to close down a toll road to reach it? Totally pointless, and I wish the manufacturers would quit using it as marketing. I guess it's a way to distract from the mediocrity the rest of the car suffers from.

      All the hate for the SS, it's actually a pretty decent offering, it even beat out its one close rival, the Charger SRT8, in pretty much every category when tested by Car and Driver. The Charger was quicker in a straight line, but also optioned up to be $9000 more expensive (55K), had a worse transmission, was quite a bit heavier, and couldn't handle half as well.
