2010 Hennessey Z700 – Click above for high-res images

Hennessey Performance Engineering makes the point that track-oriented Porsche owners can opt up from a normal 911 to a GT3 RS and Viper owners can choose the ACR edition, so what's out there for ZR1 owners who want a more hardcore machine? To answer that question, HPE has introduced the Z700 for 2010.

The exclusive new model features a number of enhancements that go beyond the requisite power increase, which in this case jumps from 638 to 705 dyno-tuned hp. HPE has also put the ZR1 on a diet, shedding pounds by adding lightweight carbon fiber seats and carbon fiber wheels wrapped in a Michilin Pilot Cup Sport tires. The wheels alone scrub off 60 lbs. of rotating weight. Aero enhancements include Hennessey's Z-Aero carbon fiber front splitter, canards and rear spoiler, all of which add 300 lbs. of downforce. Finally, an alcantara steering wheel and shift knob should feel better in the hand when barnstorming the track.

Hennessey plans to prove that the Z700 is a big improvement over the ZR1 by taking direct aim at the standard car's Nürburgring lap time of 7:26. They'll be flying to Germany with a Z700 later this year to take their best shot, but considering that HPE is perhaps the only only tuning company with its very own on-site track, Lonestar Motorsports Park, we expect good results.

Only 24 examples will be produced, and customers who order a Z700 also get a one-day performance driving instruction course at Lonestar Motorsports Park. Total cost for a base Z700 will start at $207,150, which also includes the cost of a donor ZR1. That's nearly a six-figure increase over the base price of a ZR1, so we'll have to wait until it sets some lap times to see if it's worth it.

Hennessey Throws Hat in the "Ring"

Announces Limited Edition 705 hp Z700
Nurburgring-Tested Track Upgrade for the 2010 Corvette ZR1

SEALY, TX – The world's fastest and most powerful production Corvette, the 638 bhp ZR1 has become the pinnacle of American sports cars. For most ZR1 owners, having a car capable of Nurburgring times of 7:26 is more than enough to satisfy performance to satisfy their need for speed. However, for the select few who subscribe to the mantra of "Too much horsepower is never enough" Hennessey Performance Engineering (HPE) has something special in store for them in 2010. HPE is happy to introduce the company's 705 bhp Z700 upgrade package for the 2010 ZR1.

Porsche 911 owners wanting the ubber Porsche can order the GT3 RS. Dodge Viper enthusiasts wanting the ultimate road race Viper have the ACR. Now ZR1 owners can opt for the Hennessey Z700 upgrade for their Corvettes.

Hennessey's Z700 performance package starts by upgrading the engine supercharger, exhaust and air induction systems and is dyno tuned to 705 bhp. But this is just the beginning. Additional upgrades include lightweight carbon fiber wheels with Michelin Pilot Sport Cup tires, which reduce rotating weight by nearly 60 lbs. Hennessey's Z-Aero ™ carbon fiber front splitter, canards and rear spoiler also add over 300 lbs of down force helping to put the added power to the road and track. Rounding out the Z700 upgrade package is a revised interior with lightweight carbon fiber seats, Alcantara steering wheel and shift knob.

HPE will be throwing its hat in the Ring – literally – and plans to begin testing the Z700 at the famed Nurburgring in Germany later in 2009. The company plans to build just 24 copies of this limited edition Corvette ZR1 for the 2010 model year. Each buyer gets 1-day of performance driving instruction in his or her new Z700 at Hennessey's own private test track, Lonestar Motorsports Park. Lonestar, which is located next to the company's facility, is located just west of Houston, Texas and has a full ¼ mile dragstrip as well as a 1.1-mile road course, which will soon be under construction.

      If Hennessey were that bad, he would be dead or in jail. Since he is neither, I imagine a few haters and " blind sheep" just following them cause a big noise.

      Don't be a blind sheep. Think for yourself.

        • 5 Years Ago
        "there are countless car forums out there where he has made an ass out of himself by posting childish, racist and homophobic remarks."

        That is no proof at all. Since when is an internet user ID proof of someone's identity? Based on the number of haters out there, it could be countless people posting things under his hame.
        • 5 Years Ago
        Exactly, I bet there isn't one basher on this forum that has any first hand knowledge of the product. The piling on effect with these stories is just dumb and is little more than mob mentality. If someone bases all their hate on internet forums stories than they are pretty weak minded.

        You can look at every single company in America and they will all have complaints of bad customer service from one source or another.

        All the whining about the guy from people who have never owned his products is really annoying and childish.

        scroll through a few pages and you will see what kind of person this guy is.

        @ Redeemed

        dont be so naive.

        the link i posted is a great example someone doubted his true identity on those forums too. The John Hennesey on there had vendor status, had been contacted by many forum members for sales inquiries, and even confirmed by the admin to be the John Hennesey.

      I'm interested to see if they actually get this out to the ring...and if they do...I wonder if the driver and car will survive the trip...

      At the ridiculous speeds the ZR1 is cabaple of, I wonder how much room for improvement there will be. It seems like the driver's fearlessness is more of a limiting factor than weight or horsepower.
        • 5 Years Ago
        funny point but probably only partialy true.... The test drivers are usually professionals who can drive cars to their limit which in threory should take advantage of any upgrades in power and weight.
        • 5 Years Ago
        I agree with you, but my point is that pushing a car to it's envelope on Laguna Seca or a tuner's test track is one thing...but the Ring is a breed all its own. Also, I would argue that the differences from one driver to the next are most likely more significant than tweaked power and weight. It will be interesting to see how Hennessey compares.
      • 5 Years Ago
      Maybe AB is on the Hennessey pay list.
        • 5 Years Ago
        Then again there have been some articles posted that aren't really auto news and are just here to stir up the commenting system...I'm wondering if these Hennessey articles are part of that.
        • 5 Years Ago
        One would certainly think so...I don't think I go two weeks w.out hearing something about Mr. Hennessey from AB.
      • 5 Years Ago
      If you are going to keep talking about this douche, why don't you post articles on how many people he has scammed? To give people an unbiased view of him.

      There is plenty of PROOF as many of us have seen it first hand.
      Try doing a legal search on him and you will see many claims against them but of course they are liars also. :-((

      He is a idiot to say the least.

      In late 1990's he was running all over cyberspace making claims of his handy work and claiming he could out shoot any of us ZR-1 Corvette owners.

      I personally put together the first ZR-1/Viper topgun shootout at a dragstip in Ca.
      For months he ran his mouth off, lots of press on this day of drag racing.
      Many Viper owners decided to attend as they were sucked into thinking JH would show up and beat us.

      End results the little boy JH never showed !

      We chewed up what Vipers showed including those who had JH mods done.
      He is FOS and pretty images you see on here are nowhere near being fact or real and never will be other then a few suckers getting taken.
        • 5 Years Ago
        Of course he is still in business! First he takes your money, then he takes your car, and proceeds to sell parts off your car. He just pays $30 a month so he can turn the lights on in his "shop" and puts the rest of the money in a bank account - or spends it on something. It is not hard to stay in business, when you still are getting money from people you con, and don't actually buy or produce anything
        • 5 Years Ago
        Once again, all your paragraphs after paragraphs here prove is you can read internet stories. That's it. Have you owned one of these cars? No, so I don't really care about what you have read or have heard.

        Look, I could care less about Hennessey as a person. He has some bad customer service, no doubt. But he makes cool cars and someone is buying them hence he is still in business year after year. Many other car speed shops have fallen by the wayside and yet he remains in business.

        Bottom line, talk about the car and less about hating on the owner of the company. I'm tired of all the hate and I'm not the only one here. If he bothers you so much than don't read these stories anymore. Better yet, don't post here period.

        • 5 Years Ago
        They why isn't the guy in prison???? It's really low class to accuse someone of being a criminal while hiding behind your computer screen soley based on internet stories.

        I'm convinced some of you people here only live to complain about something. Tear others down because you have nothing of your own. Pathetic.
      • 5 Years Ago
      Maybe your readers haven't made this clear enough...


      I'm pretty sure we can't say it much simpler.
        • 5 Years Ago
        Would I do business with him? Probably not but I still want to read about the cars and see the pics.

        There is nobody forcing you to buy his products so stop the whining.
        • 5 Years Ago
        AGREED.....i don't care what kind of car they build!!!
        • 5 Years Ago
        "Only 24 examples will be produced,"

        i found a typo! 24 examples is far to high, its more like 1...

        seriously... please STOP with articles on this guy...

        Does Autoblog really pay attention to peoples comments? i love the site, but talk about epic fail here...
        • 5 Years Ago
        Blame it on the a-a-a-a-a-alcohol.
      • 5 Years Ago
      I've had enough reading how people whine like children on someone else's blog...

      It's AB, written by AB... if you don't like what's posted, don't read it... if your eyes can't even choose without others needing to remove articles, then YOU have a problem... nothing to do with the blog..

      It's a post about a car, we're here for the pics and that's all, nothing about ZOMG Hennessey is a bad dude... who cares about the dude/company/posts it's about the car...

      IT'S A CAR BLOG for christ sakes... oh wait, if you start blanking out on certain cars, then how is it a car blog?
      • 5 Years Ago
      In related news, Hennessey wiped his a$$ and AB was there to cover it. Stains were reported to be of a BBQ variety....
