[VIDEO] Corvette ZR1: Factory Assembly Process

by Keith Cornett on June 18, 2008

The 6.2L Supercharged Corvette ZR1

I received a text message yesterday from GMnext.com alerting me that a new video showcasing the assembly of a Corvette ZR1 was online. The video starts with the ZR1′s frame and follows the assembly process until the Corvette is completed and driven out to the back lot ready to be transported. One aspect of the video that I really enjoyed was hearing the comments made from the assembly plant workers who speak about the Corvette ZR1 with pride and enthusiasm.

Corvette ZR1: GM Releases Official Pricing

by Keith Cornett on June 17, 2008

The 6.2L Supercharged Corvette ZR1

Seems like it was forever-ago when the 2009 Corvette ZR1 was introduced at January’s GM Style event. With all the fanfare and Kid Rock to boot, the Corvette ZR1 single-handedly took over the North American Internation Auto Show. Six months later and just one month before the 6.2L Supercharged carbon fiber wonder begins production, GM is giving us the final piece of the Corvette ZR1′s puzzle: pricing and official performance statistics.

The official MSRP of the 2009 Corvette has been set at $103,300, making the Corvette ZR1 the most expensive Chevrolet ever offered. The MSRP includes the $850 destination charge that’s on every Corvette. An options package is also available for $10,000 and the chrome wheels will set you back another $2,000. Finally, and most unfortunately, the Federal Government gets in on the act with a $1,700 gas guzzler tax. So for those of you keeping track, a fully loaded 2009 Corvette ZR1 will cost you $117,000.

So what are you getting for $117,000? How about an American Super car that can stack up against any competition, foreign or domestic. We saw how the engineers ran the Corvette ZR1 to a top speed of 205 mph (330 km/h) on a German test track. Now we learn that the ZR1 can run 0-60 at 3.4 seconds, 0.3 seconds faster than the Z06, and its 0-100 mph is 7.0 seconds for the ZR1, almost a full second faster 7.9 seconds posted by the Z06. Finally, the all-important quarter mile time is 11.3 seconds at 131 mph.

“A favorable power-to-weight ratio gives the ZR1 an advantage over the competition and performance that has to be experienced to fully appreciate,” said Tom Wallace, Corvette chief engineer. “Of course, on a racetrack, drivers of competitors’ cars may appreciate the ZR1 in a whole different manner.”

The Corvette ZR1 has an EPA fuel rating that also beats several renowned super cars. The ZR1 is estimated to get 14 mpg city and 20 highway. Ferrari’s 599 GTB Fiorano gets 11 city/15 highway, the Lamborghini Murcielago gets 8 city/13 highway and the Aston Martin V8 Vantage gets 12 city/19 highway. As Corvette’s Chief Engineer Tadge Juechter acknowledged in April’s Live Chat, the Corvette ZR1 is subject to a modest gas guzzler tax of $1,700.

While the standard Corvette ZR1 is based on the same interior refinements of the Corvette Z06, for the discriminating buyer with an additional $10,000, Chevrolet is offering an Options package that includes the following upgrades:

  • Power-adjustable, heated and leather-trimmed ZR1 embroidered sport seats
  • Side air bags
  • Bose premium audio system
  • Navigation system
  • Bluetooth connectivity
  • Power telescoping steering column
  • custom leather-wrapped interior available in four colors

The only other option available for the Corvette ZR1 are Chrome Wheels, which will add an additional $2,000 to the MSRP.

The Corvette ZR1 has been a long time coming and with production starting in July, it should be just a couple of more months before we start seeing them at shows and on the street. Chevrolet has produced a true super car that’s ready to compete on the world stage. Now, about the C7 Corvette…

The 2009 Corvette ZR1

Dealers, do you know where your 2009 Corvette ZR1 allocation letters are? We heard the letters were promised in “early May” and being so close to the date that the system will start accepting orders for the 2009 models, it’s unusual that they haven’t shown up yet. We already know that yearly production will be 2,000 units according to Chief Engineer Tadge Juechter, so what’s the holdup in letting dealers know their preliminary allocation numbers? It could very have something to do with pending legislation in Florida that would cause a ripple effect across the country for not only allocations of the Corvette ZR1 but the Z06 as well.

On May 1st, the Florida Legislature approved a bill pertaining to Motor Vehicle Dealers and their relationship with the licensees (ie manufactures) and sent it to the desk of Governor Charlie Crist for his signature. The 17 page bill, titled “CS for SB 2582” contains language that prohibits certain actions that licensees can take against a dealer including coercion to improve or relocate facilities or punishing dealers for selling motor vehicles knowingly to customers who intend to export them.

However, there are two sections of this bill that deal with fairness of allocations. It is specifically these two clauses that could effect the allocation of a limited production car like the 2009 Corvette ZR1. The worst case scenario is that no Florida Chevrolet dealers will receive the ZR1 because if GM makes one available to any dealer in Florida, than technically it would have to make one available to all dealers in the state, which is what it seems the bill requires.

The two clauses in “CS for SB 2582″ dealing with allocations are below with the relevant passages highlighted:

(18) The applicant or licensee has established a system of motor vehicle allocation or distribution or has implemented a system of allocation or distribution of motor vehicles to one or more of its franchised motor vehicle dealers which reduces or alters allocations or supplies of new motor vehicles to the dealer to achieve, directly or indirectly, a purpose that is prohibited by State Statute 320.60-320.70, or which otherwise is unfair, inequitable, unreasonably discriminatory, or not supportable by reason and good cause after considering the equities of the affected motor vehicles dealer or dealers. An applicant or licensee shall maintain for 3 years records that describe its methods or formula of allocation and distribution of its motor vehicles and records of its actual allocation and distribution of motor vehicles to its motor vehicle dealers in this state. As used in this subsection, “unfair” includes, without limitation, the refusal or failure to offer to any dealer an equitable supply of new vehicles under its franchise, by model, mix, or colors as the licensee offers or allocates to its other same line-make dealers in the state.

(22) The applicant or licensee has refused to deliver, in reasonable quantities and within a reasonable time, to any duly licensed motor vehicle dealer who has an agreement with such applicant or licensee for the retail sale of new motor vehicles and parts for motor vehicles sold or distributed by the applicant or licensee, any such motor vehicles or parts as are covered by such agreement. Such refusal includes the failure to offer to its same line-make franchised motor vehicle dealers all models manufactured for that line-make, or requiring a dealer to pay any extra fee, require a dealer to execute a separate franchise agreement, purchase unreasonable advertising displays or other materials, or relocate, expand, improve, remodel, renovate, or recondition, or alter the dealer’s existing facilities, or provide exclusive facilities as a prerequisite to receiving a model or series of vehicles. However, the failure to deliver any motor vehicle or part will not be considered a violation of this section if the failure is due to an act of God, work stoppage, or delay due to a strike or labor difficulty, a freight embargo, product shortage, or other cause over which the applicant or licensee has no control. An applicant or licensee may impose reasonable requirements on the motor vehicle dealer, other than the items listed above, including, but not limited to, the purchase of special tools required to properly service a motor vehicle and the undertaking of sales person or service person training related to the motor vehicle.

As the Corvette ZR1 is considered its own model, any dealer not allocated a ZR1 could technically invoke these clauses and force a claim against GM for violations. While the clauses would also apply to the Corvette Z06 because its also considered a “model”, our understanding of the bill is that special editions like the Indy 500 Pace Car replicas would be exempt as they are technically an option on a convertible or coupe, and not considered its own “model”.

It’s easy to see the dilemma that GM faces. General Motors has a mathematical formula for which of the 4,000+ Chevrolet dealers that would be able to sell the 2,000 Corvette ZR1s (not taking into consideration that some of that number is planned for export) and if this legislation is passed, GM may be forced to exclude the Sunshine state altogether from its ZR1 allocations unless they want to offer one to every Florida-based dealer first. As you can see, this decision could cause a ripple across the US with thousands of dollars of profit per ZR1 at stake.

We’ll be watching MyFlorida.com for announcement on whether this bill will be signed or vetoed.

The Corvette ZR1 at a German McDonalds

So you’re an American in Germany, home of the beerhouse and wiener schnitzel and you’re hungry. So where do you go to grab something fast and familiar? McDonalds of course! The Corvette ZR1 is shown here sitting in a parking lot at a local German McDonalds while the drivers are no doubt filling themselves up on “Royales with Cheese”.

More photos after the jump.

The Corvette ZR1 at a German McDonalds The Corvette ZR1 at a German McDonalds The Corvette ZR1 at a German McDonalds

Team Corvette has been in Germany with the ZR1 doing their high speed testing around the Nürburgring. Corvette’s Chief Engineer Tadge Juechter said that the “ZR1 will beat the track record for production cars at any road course in the world” and that he expects a ‘ring lap time of around “seven minutes twenty something seconds.”

According to Autogespot.com, “Hij is gespot! Er zwerven al geruime tijd spyshots over het net en nu is hij open en bloot gespot op de parkeerplaats bij een McDonalds in Duitsland. De Corvette ZR1 zal volgens de heren van Corvette in staat zijn ieder record van productie-auto’s op ieder circuit te verbeteren. ”

Using Google’s Dutch to English transltor:

“He is spotted! There has long been spyshots wander through the net and now he is openly spotted at the parking lot at a McDonalds in Germany. The Corvette ZR1, according to the lords of Corvette capable of any record of production cars at any circuit.”

It appears that GM’s Corvette guys have a soft spot for fast food. Back in March, we brought you the video of a group of Corvette ZR1 drivers filling up at a Wendy’s in Bowling Green, Kentucky before making the long trek to Detroit.

Lastly, I’ve got to ask, what is up with that German McDonald’s parking lot configuration?

2009 Corvette ZR1 on the Nürburgring

BridgetoGantry.com has seen spotted Corvette’s ZR1 yesterday at the Nürburgring. Dale Lomas, writing for the officially unofficial track blog states that the weather has been warm and dry over the previous days and that has brought out Team Corvette and their supercharged 638 hp Corvette ZR1, this time dressed in red. Dale goes on to speculate that GM may have been looking for a lap time as he “spotted a helicopter chasing something that sounded very V8 and awfully supercharged…”

2009 Corvette ZR1 on the Nürburgring

Although that may be the case, the photos again show a passenger riding shotgun so its doubtful that an attempt to lap the ‘ring in “seven minutes and twenty-something seconds” as Corvette’s Chief Engineer Tadge Juechter alluded to last week was happening when these photos were taken.

As for the helicopter? The ZR1 has proven to be a boon for spy photogs and it wouldn’t come as a surprise to see arial footage of the new supercharged bad boy making its way around Nürburgring’s Nordschleife.

2009 Corvette ZR1 on the Nürburgring

When news hit last month of the 2009 Corvette ZR1 running the Nürburgring, many of us were a bit disappointed to hear that lap times were averaging in the low 7:40s. After all, Jan Magnussen took a 2005 Corvette Z06 around the ring in 7:42.9 and the new Corvette ZR1 should be faster than that, right? So we kept reminding ourselves about how the track was wet and cold and that the timing was by hand and that the car held two occupants. Corvette’s Chief Engineer Tadge Juechter told us not to worry as the “ZR1 will beat the track record for production cars at any road course in the world.”

That’s a fairly tall order, especially in the light of the recent 7:29 Nürburgring performance by Nissan’s GT-R. Think about that for a minute. The Corvette Z06 piloted by a professional race car driver was nearly 14 seconds slower than the new AWD wonder. But does that make Tadge back down? Of course not, we’re talking about Team Corvette! According to Edmund’s Inside Line, Tadge said they’re expecting a lap time of “seven minutes, twenty-something seconds.”

Wow! I love the fact that our boys are confident in the ability of the Corvette ZR1 to perform and a lap of the 7:2X time would certainly make any sport car enthusiast familiar with the ‘ring say “%^$#!”

There’s no telling when the timed attempt at Nürburgring history will occur. Despite being at the famed 12.9 mile track last month, the ZR1 Corvette that GM used was a testing car and not a regular production model. And in the chat session early this week with Corvette enthusiasts, Tadge said in response to a question about the Corvette ZR1 taking on the World Speed Endurance Record like the 1990 ZR-1 that “we are currently focused on a perfect launch and getting the ZR1 into production. We will talk about record attempts later”.

So for now we’ll have to wait and see. My thoughts are that this will happen sooner rather than later, but it’s ultimately up to GM. Let’s just hope they add a bit of weight to the car in the form of an onboard camera when the attempt is made.

The 2009 Corvette ZR1

Corvette’s Chief Engineer Tadge Juechter hosted a chat on the GMNext.com website this afternoon to discuss the 2009 Corvette ZR1 so we made sure not to miss it! What did we learn from the Corvette Chief today? Plenty. Tadge touched on a variety of subjects relating to the Corvette ZR1 including early concepts to the engineering challenges faced by the team. Continue reading for more of Tadge’s comments plus the complete chat transcript.

Tadge was asked about the fuel economy testing and he said all that would be happening within the next couple of months. The consensus from Team Corvette is that they are expecting the fuel economy ratings to be somewhat less than the Z06, and according to Tadge, GM is also expecting the Corvette ZR1 to be subject to the gas-guzzler tax, albeit a small tax.

On the subject of the much debated polycarbonate window hood, Tadge said the reason for its inclusion was two-fold. “We minimized the clearance between the engine and the hood to maximize forward vision from the driver’s seat. This dictated a very close tolerance between engine and hood skin. Design helped make this need an aesthetic ‘win’ also by covering the intercooler with the transparent panel. You can see the engine move under the hood and since we have only a thin pane of polycarbonate, the hood surface is very low.”

As for the naming of the ZR1, GM once again turned to heritage. “The reason we named this model the ZR1 is because this version is virtually the same as the C4 ZR1. Both ZR1s introduced new engine technology to the Corvette while the C4 ZR1 was the first multi-valve engine in a Corvette and the C6 ZR1 is the first super-charged engine in a Corvette. Also, philosophically, both cars represent the top of the Corvette line. In other words, the ultimate Corvette. Max performance both on the track and on the street and fully contented.”

The chat forum is an excellent opportunity for GM staff to interact with owners and enthusiasts and we encourage them to continue the chat series with other members of the Corvette team. Turnout was a lot lower than I expected with the number of participants reaching a high of 18. Still, we appreciate the fact that Tadge and the other GM members provided a very interesting and enlightening afternoon event.

Finally, GM has set up a dedicated Corvette ZR1 area at www.ZR1.GMNext.com The mini-site includes photos, videos and the history of America’s favorite supercar. They also have set up a mobile ZR1 news alert function. To subscribe, text ZR1 to 466398 for exclusive ZR1 news and information delivered directly to your cell phone.


Here is the entire chat transcript:

Vince Muniga – GM:
Hello Corvette fans. I’m Vince Muniga and I’ll be moderating this chat session today. Today’s chat will be with Tadge Juechter. Tadge is the Vehicle Chief Engineer for the Corvette ZR1 and he is excited to be taking your questions today. Today is the first in a series of chats around the ZR1 and will focus on the name and history behind the car. To see the ZR1 hit 205 mph at the test track, check out Tadge’s blog at http://blog.gmnext.com/?p=133. We’ll get started right at 3 p.m. EST.

Vince Muniga – GM:
O.K., let’s get started with the first question

CorvetteBlogger:
What’s the target production for 2009?

Tadge Juechter:
Hello Corvette fans!

Tadge Juechter:
Production will start this summer and we can produce approximately 2000 ZR1s per year for the world.

CDINGERS:
Tadge – Great Presentation at the C5 – C6 Bash. Is there any way to post a copy of the presentations?

Tadge Juechter:
We are not posting those presentations at this time. However, many of the slides were photographed and posted by others.

RobertNH:
Tadge, can you tell us what the expected fuel mileage will be for the ZR1 and whether or not it will be subject to a gas guzzler tax?

Tadge Juechter:
We have not run our fuel economy testing yet. It will be somewhat less than a Z06 and we expect a small gas guzzler tax. However, the ZR1 will be the most fuel efficient 600 hp car you can buy in the world.

CDINGERS:
What changes to the ZR1 LS3 block will carry over to the production LS3? Oil Squirters, 11mm head bolts, etc.

Tadge Juechter:
The block structural improvements and the improvement in bay to bay breathing will be included in LS3 blocks for 2009.

RobertNH:
How is the overall vision of the C6 ZR1 different from the overall vision of the C4 ZR1?

Tadge Juechter:
The reason we named this model the ZR1 is because this version is virtually the same as the C4 ZR1. Both ZR1s introduced new engine technology to the Corvette while the C4 ZR1 was the first multi-valve engine in a Corvette and the C6 ZR1 is the first super-charged engine in a Corvette. Also, philosophically, both cars represent the top of the Corvette line. In other words, the ultimate Corvette. Max performance both on the track and on the street and fully contented.

RobertNH:
Any plans to take on the World Speed Endurance Record like the 1990 ZR-1 did?

Tadge Juechter:
As you probably saw, we announced the top speed (2 way, 1 mile average) as 205 mph. The ZR1 has also been extremely durable in our testing, so the car certainly has the potential to take the World Speed Endurance Record. However, we are currently focused on a perfect launch and getting the ZR1 into production. We will talk about record attempts later.

CorvetteBlogger:
GM renewed the ZR1 trademark in late 2006. When was the decision made to call the “Blue Devil” the ZR1 and were any of the names that showed up in the automotive press (ZL1, Z07, SS, Stringray) ever considered?

Tadge Juechter:
The ZR1 naming decision was finalized in September 2006. We considered a lot of alternatives, but once we settled on the ZR1 and saw the graphics and badges that design had come up with, we knew that it was the right direction to go.

CDINGERS:
Do you have an time line of when pricing, 1/4 mile times, results from the “loop” will be available?

Tadge Juechter:
We expect to announce pricing in May and all performance numbers will be run with production vehicles over the next two months.

RobertNH:
From an engineering standpoint, what was one of the most difficult aspects of the 2009 ZR1 to bring to production?

Tadge Juechter:
Managing underhood and underbody temperatures was the biggest challenge for the engineering team. Keeping the inlet air cool through the intercooler (a big contributor to power) was especially challenging.

CorvetteBlogger:
Did Pratt & Miller/Corvette Racing play any role in the development of the ZR1?

Tadge Juechter:
Yes. We used Pratt & Miller’s analytical capability extensively for optimization of aerodynamics and brake cooling.

CDINGERS:
When did the program / vision start? There was a comment at the bash about 6 years ago.

Tadge Juechter:
Concepts were talked about as early as June 2001.

CorvetteBlogger:
Tell us about the debate (if any) regarding the inclusion of the see-through hood panel? Was it strictly cosmetic or is there another purpose like fit?

Tadge Juechter:
The hood window is both an aesthetic and funtional feature. We minimized the clearance between the engine and the hood to maximize forward vision from the driver’s seat. This dictated a very close tolerance between engine and hood skin. Design helped make this need an aesthetic “win” also by covering the intercooler with the transparent panel. You can see the engine move under the hood and since we have only a thin pane of polycarbonate, the hood surface is very low.

CDINGERS:
Will the ZR1 go forward as a C7 as the Z06 did?

Tadge Juechter:
It is too early to say anything about C7. When we get to C7, of course we will consider a ZR1 model.

CorvetteBlogger:
When building a car like the ZR1, how much input comes from customers during the development period?

Tadge Juechter:
Our team attends a lot of Corvette events as well as monitoring Corvette forums and anytime we ask Corvette enthusiasts what they’d like to see in a new Corvette, the number one answer is more horsepower. Many of us on the Corvette team are also Corvette owners and enthusiasts.

CDINGERS:
How much total weight was saved by the use of carbon fiber?

Tadge Juechter:
The visible carbon fiber roof panels saved 6.6 pounds. The ZR1 hood weighs 7.5 pounds less than the Z06 hood. We concentrated lightweight materials in the front and height of the vehicle to lower the center of gravity and improve weight distribution.

RobertNH:
Is there a particular engineering feature, or aspect, that you and/or Corvette Engineering were hoping to see go into production on the 2009 ZR1, but due to cost or timing constraints was not possible?

Tadge Juechter:
No, we are very happy with the final production execution of the ZR1. Actually, our final power numbers exceeded our original projections.

CorvetteBlogger:
Will we see ZR1 specific options be made available for the Z06 ie carbon ceramic brakes and michelin tires?

Tadge Juechter:
There are no plans at this time.

CDINGERS:
How much additional downforce is generated by the ZR1 wings over the current Z06

Tadge Juechter:
ZR1 aerodynamic features add approximately 30 percent more downforce in the front and 45 percent more on the rear.

RobertNH:
Why was the decision made to go with Michelin rather than Goodyear for OEM tires?

Tadge Juechter:
We always pick the supplier that can produce the best product. Both Michelin and Goodyear submitted excellent proposals. However, Michelin’s was superior.

Tadge Juechter:
To go back to an earlier question on mass savings, the ceramic brakes saved 2 kilograms per corner over the Z06 and five kilograms per corner versus a similar capability iron brake system.

RobertNH:
There’s been a lot of misconception in the press about the cost of the product used in the carbon fiber clear coat. I understand that a very small percentage of this product is used in the clearcoat. How much of this product is used per car and can you say exactly what the product is that prevents UV degradation of the carbon fiber?

Tadge Juechter:
The protective material is proprietary to General Motors. It was developed to protect circuit boards from environmental corrosion. It is mixed in a three percent solution into the clear coat. The material itself does cost $60,000 per gallon. The resulting clear coat mixture costs $2,000 per gallon. Approximately one half gallon of the clear coat is applied to the carbon fiber panels on each car.

CorvetteBlogger:
Was there a specific competitor’s model that was used as a benchmark against the ZR1 during development?

Tadge Juechter:
No specific competitor’s vehicle was targeted. Instead, we continued the evolution of the car to its most extreme capability. And thanks to input from a lot of you customers, we think we’ve built the car of your dreams.

RobertNH:
What are differences between the MSRC system on the ZR1 and the MSRC system on the base model and will the changes or refinements seen on the ZR1′s system trickle down to the base model?

Tadge Juechter:
The second generation MSRC dampers were introduced last year for the 2008 model year. They are specifically tuned this year for ZR1 duty along with the springs and the largest stabilizer bars ever put on a C6.

CDINGERS:
In the painting process is the new carbon fiber clear coat applied to the entire car or just the carbon fiber parts?

Tadge Juechter:
Just the visible carbon fiber parts.

RobertNH:
Will GM Service Technicians need to undergo any special training to service the ZR1 and will special tools need to be used to conduct engine work like they were for the LT5 engine?

Tadge Juechter:
Yes. Like the Z06, the ZR1 has enough specialized content that some additional training will be required. It will not be nearly as complicated as the C4 ZR1 or the C4 LT5.

CorvetteBlogger:
What were your thoughts when you saw the first production ZR1 sell for $1 million at Barrett-Jackson in January?

Tadge Juechter:
H-o-l-y #$%@! haha

Tadge Juechter:
You all may be interested in other 2009 product enhancements such as variable ratio steering, and Bosch brake apply hardware for all Corvette models.

RobertNH:
When the 2009 ZR1 was originally conceptualized, was there a target market that GM had in sight, for example, Ferrari/Porsche owners, etc?

Tadge Juechter:
The Z06 showed that we could compete with much more expensive models from the other makers. The ZR1 raises the bar even higher.

CDINGERS:
Tell us more about the Boach Brakes for 2009

Tadge Juechter:
All Corvette models will be getting Bosch-produced brake master cylinder, booster and ABS module. These parts replace Delphi sourced material from prior years. All models get refined calibration of ABS traction control and stability systems for 2009. We are showing improvements in all areas including stopping distance.

RobertNH:
Due to the immense power of the ZR1 and the need to try and keep it planted, was an all-wheel drive system ever considered during the development phase of the car?

Tadge Juechter:
No, all-wheel drive would have added too much mass. I believe we are the lightest 600 hp car you can buy. We focus on power-to-weight ratio and maximizing traction in a real-wheel drive configuration.

lt5405:
Will Chevrolet intervene in Dealer price gouging?

Tadge Juechter:
We’re strongly encouraging dealers to charge MSRP.

RobertNH:
Well, I think I’m actually out of questions. Thank you Tadge for taking the time to chat with us and provide the information you did. The 2009 ZR1 is fantastic and I’m hoping that someday I can park one next to my 1990! Keep up the great work!

Tadge Juechter:
Thanks for your questions. I hope you get that ZR1, too. We think it will exceed your expectations.

Vince Muniga – GM:
Thank you for joining Tadge on today’s chat and all the great questions. We’re sorry we couldn’t get to all your questions and we’ll certainly try to answer the questions in further chats. If you’d like a transcript of today’s chat, it will be posted on GMnext.com later this week. For a complete look at the ZR1 including photo, videos and the history of America’s favorite supercar, visit www.ZR1.gmnext.com. You can also text ZR1 to 466398 for exclusive ZR1 news and information delivered directly to your cell phone. Thanks again!

CorvetteBlogger:

The 6.2L Supercharged LS9 V8

We had a feeling GM was sandbagging us with the production specs of the 2009 Corvette ZR1 back in December. 620 horses is equal to one hundred horsepower per liter they told us. Revised specs in the Spring, we heard. Well, it’s unveiling time at the Museum’s C5/C6 Bash and GM finally makes the Supercharged LS9 6.2L V8 power specs official: The new 2009 Corvette ZR1 produces 638 horsepower and 604 lb-ft of torque.

The LS9’s output is nearly 103 horses per liter, or just about 1.7 horses for each of the engine’s 376 cubic inches. It is unquestionably the most powerful automotive production engine ever manufactured by General Motors and enables the Corvette ZR1 to achieve a top speed of more than 200 mph (322 km/h).

So what does the view look like at over 200 mph? Watch the video below and you’ll see the Corvette ZR1 hitting 205 mph on a test track in Papenburg, Germany. The Corvette is on what looks like a two lane highway when the hammer is dropped. When a high bank corner comes in view the ZR1 slips effortlessly around it, making the other cars on the track look like they’re standing still. What’s amazing is how smooth the ride appears to be. Watch the steering wheel at 200 mph and there’s barely any movement.

There are only a couple of pieces to puzzle remaining that we still don’t have answers for, including the all important “How Much?”. The other is mostly unimportant to the buyer of a Corvette ZR1: city/highway gas mileage ratings. For what its worth, GM’s engineers are confident the ZR1 will be the most fuel-efficient 600-plus-horsepower car on the market.

Finally, mark your calendars for July 14th as that is the start of production for the greatest American sports car the world has ever seen.
