    General Motors talks up the Corvette ZR1 in a new ad

    General Motors talks up the Corvette ZR1 in a new ad

    Submitted by Patrick Rall on Wed, 03/23/2011 - 19:55

    This past weekend brought the racing world the 59th running of the 12 Hours of Sebring but before General Motors was permitted to enter their race-built Corvette ZR1 in the American LeMans Series (ALMS), they were asked to modified the ZR1 for the race - by removing 168 horsepower.

    The American LeMans Series GT class is comprised of some of the most recognizable street cars in the world, with competitors from BMW, Ferrari Porsche and Chevrolet among the regular heavy hitters and with GM touting the Corvette ZR1 as one of the world’s best-performing sports cars, it would only make sense that the highest performance Corvette ever would take to the track at Sebring. The problem (for GM) is that the ALMS required the automaker to strip 168 horsepower from the supercharged V8 supercar, effectively cutting the output of the LS9 from 638 horsepower to “just” 470.

    It is not at all unusual for a company to perform some heavy modifications to even the world’s best sports cars before a they can last through a half-day marathon of auto racing like the 12 Hours of Sebring. However, for GM to be required to water-down the Corvette ZR1 so substantially before entering the ALMS was big enough news that the company has put together a new commercial spot bragging about the amount of power pulled to make it “fair” for some of the biggest names in the sports car world.

    Unfortunately (again, for GM) stripping 168 horsepower from the race-ready Corvette ZR1 proved to be a bit too much as the top two spots in the GT class were claimed by a pair of BMW M3 coupes but the detuned Corvette ZR1s finished 3rd and 4th - beating the best from Ferrari, Porsche, Jaguar, Lamborghini and Doran Ford.

    Even though the Corvete ZR1 didn’t take the win, General Motors offered up a new commercial (check it out below) featuring a handful of clips of the black and yellow ZR1 GT racer practicing, mixed in with shots of a white ZR1 used in the Corvette commercial that launched in 2010. The commerical boasts that the Corvette ZR1 is so powerful that GM was forced to pull power to make it fair for the other teams. While GM didn’t win, this commercial pokes fun at the competitors that were able to beat the watered down ZR1.

    Does this guy know that the Pratt & Miller GT2 Corvette does not run an LS9... but a GM built 5.5L v8 that is required by ALMS rules?

    Heres a snapshot I took of the engine, since I was @ Sebring this past weekend!

    It is a good sounding engine - and not bad HP #s if going by that article.

    470hp with 5.5L's , e85 for fuel - not bad at all.

    Isn't it based on the Gen-V V8?

    I was wondering the same thing - I thought that the new 5.5 ltr racing motor was to serve as the basis for the next gen small block?

    Yes - built in house from GM. If you look at the back of the block it says 7.0 stamped on the back of it. I do not think that Katech developed this motor like that did the C5R and C6R blocks....

    the corvette has to run (2) 28MM air restrictors in the induction system. all the engines in this class have some type of air restrictors to even up the HP so no one has a advantage

    the engines have to use production cylinder blocks

    Anyone who follows road racing will heavily discount the misleading ad. I'm a big Corvette fan, however, I don't for one second believe that BMW didn't deserve the win even though the #4 Corvette lost 3 laps early in the race because of an unfortunate accident. It made up two of them.

    Re: General Motors talks up the Corvette ZR1 in a new ad

    The Corvette team did a great job but I do think that they will come back strong as they continue to improve upon the race car. They do great work and I don't doubt that they will be making the car a greater force to be reckoned with.

    In the sea of new automotive faces,
    there's nothing like the appreciation and beauty of an older model. Let's represent!

    Re: General Motors talks up the Corvette ZR1 in a new ad

    I know the ZR1 can't run the lemans series off the show room floor, but does anyone think it could run the 12 hours straight without problems? or 24 hours? I would love to see real cars running races again.

    GM did a 24 hour run with the original ZR-1 maybe they will do it with this one and beat their own records. read all about it. http://www.zr1netregistry.com/endurance_epic.htm

    I like the commercial.

    This GT season is going to be interesting and it really sucks that the US TV stations refused to pick up the season to broadcast. I dont get ESPN3 so I dont get to watch it at all.
