Just the Facts:
  • A leaked sketch of the new C7 shows that the 2014 Chevrolet Corvette will continue to use transverse composite leaf springs.
  • It stands to reason the same springing medium will be used in the back as well.
  • This crucial bit of information does not mean the entire suspension has been carried over.

SANTA MONICA, California — Every time a new Chevrolet Corvette comes out a certain subset of the Corvette fan base wonders if its "unique" transverse composite leaf spring will finally be ditched in favor of coil over springs and shocks. Typically, these are the folks who take their Vettes to the track, the ones who want to tinker with the setup. A handful of aftermarket companies do a brisk business selling coil-over conversion kits to supply their needs.

A leaked sketch of the new C7 that showed up on a personal Facebook page gives us the answer: the 2014 Chevrolet Corvette will continue to use transverse composite leaf springs.

The spring appears as a tongue behind the lower wishbone in the black and white line drawing of the front suspension. Compare that to the first few pictures in our suspension walkaround of the 2011 Corvette Z06 and you'll get a better idea of how it all lays out.

No similar drawing of the rear appears on the same Facebook page, but it stands to reason the same springing medium will be at work back there as well.

This crucial bit of information does not mean the entire suspension has been carried over. There's far from enough detail here to see if the geometry has changed. For that we'll have to wait until General Motors is willing to reveal more details, likely at the 2014 Corvette's big debut at the 2013 Detroit Auto Show.

For now, at least, it's safe to say that the coil-over Corvette conversion side business is alive and well. And in the Vette versus Viper wars, track day tuners that own Vipers can tweak and fiddle all they want with the factory coil-over setup while the C7 Corvette faithful will need to open up their wallet and make some fundamental aftermarket changes.

Edmunds says: This may seem like old technology to some, but Chevrolet has proven over and over again that the transverse leaf spring can be used to great effect with the right design.

    "This may seem like old technology to some, but Chevrolet has proven over and over again that the transverse leaf spring can be used to great effect with the right design." This can also be said about the Mustang's rear suspension. Sure, it works but there are proven, better designs out there. Ford and Chevy is simply thinking about keeping the cost down, nothing wrong with that.

    Based on the Corvette's various stellar track times, I don't think a low cost proven design is a bad idea by any means for the suspension.

    I'm not sure if it's a cost issue or not in this case. The Corvette C6 had double wishbones all around, and almost everything was aluminum. And I can't imagine a composite leaf spring is particularly cheap. We're definitely not seeing the same sort of overt cost consciousness we find at the tail-end of a Mustang. I suspect they prefer it for packaging reasons.

    Indeed I had always heard it was a packaging thing too.

    How do I see the other comments on this article?

    So now I can see that I can only see the comments after posting one. Edmunds, please do not kill the Inside Line approach to commenting on articles. This sucks.

    I'm not seeing the same behavior you describe here on Google Chrome and a laptop PC. I can see and read comments without being signed it at all. Yes, I have to click on the "Comments (6)" blue box to display them, but that's it. I do have to sign in if I want to post, as I did in order to write this, but that was always the case. And I checked "remember me on this computer" so I don't have to sign in again.

    ERRR... I've tried to give this a chance. But, burring comments behind a button and disabling comments from certain articles totally misses the point of a blog. We need community interaction, which cannot happen when you silence us. Though, I like the rating system for comments. There is so much potential here but management is competent.

    Off topic, but the comment section was superior on the Inside Line site.

    actualsize, the only real problem I have noticed with the site migration is that there is no way to post comments on the long term test blog.

    I miss Inside Line. :-(

    Anybody else notice that it also has a pretty good skectch of what the front end could look like?

  • jpnpower jpnpower Posts:

    Elwoodz me too, now more hast been leakest. SEESH, now I can finally get to the comments and comment. That was a hassle. Now, where is Straightline and ReadersRides... now to keep on searchings. gaaah. Well at least some of the regulars of IL have made it here.

    Wow, GM. All of this great technology added to the next Corvette, but you're still sticking it out with pushrods and leaf springs. It's really sad when all of the other sports cars (i.e. 911, Viper) have been using coil-over suspensions for years now. Even the C5-R and C6.R don't use leaf springs. What's the point of technology transfer from racing when you don't use a variant of the coil-over suspension setup from your very own race car? It's a proven setup! Maybe the next Vette gets optional Recaro seats at least.

    Wow, I can barely see any detail in your tiny photos.

    Leaf springs - on a 2014 model.... This dinosaur should have been put out to grass 20 years ago.
