Edmunds confirmed nothing of the sort. Nobody has. A seven-speed manual has been mentioned; nothing more. Reading comprehension for the win:

"Inside Line itself reported in September that "a source with knowledge of the C7 project confirmed that the upcoming Corvette will offer a seven-speed manual transmission." There's no reason for us to believe anything has changed since then. In fact, GMI confirmed that fact just last week.

But how that seven-speed comes about is open to speculation. It could simply be a single-clutch version of an automated dual-clutch seven-speed that will serve as the C7 Corvette's automatic. It could be an evolutionary development of the current Tremec T-6060 six-speed. Or it could be an entirely new, true manual transmission developed by GM.

Remember, though, that GM is developing its new full-size trucks right now. And as one GM engineer said about more gears, "It's kind of a win-win for us. More gears are good for fuel economy and good for marketing." All the economies of scale rest with the trucks and if GM feels there's a significant competitive advantage in developing new transmissions for the trucks with greater numbers of gears, then that's likely to pay off for the Corvette, too.

Inside Line's supposition is that seven- or eight-speed automatic and/or manual transmissions are inevitable from GM so the new full-size trucks can better compete in their segment. And it's from that family of transmissions that new Corvette trannies will spring. "

Remember, some people reporting may easily confuse a dual disk clutch manual with a dual clutch transmission, which it possible could be fully manual or an automated manual.

Words mean things, and sometime nuances escape people.

I don't know guys. If I have to run through 7 gears manually, that starts to become work and is no longer fun. BIG RIGS are not fun to drive.

In what scenario would you run through all seven gears? Not a run to top speed, because that won't be achieved in top gear. A sprint from a stop to freeway speed? You wouldn't go past fourth until you're done accelerating and then you'd skip to top gear. A gentler run? Skipshift.

Another gear is a good thing, if done right.

OK, so why have that many in a manual transmission then? Have a 6 speed with the 5-6 shift at huge difference and call it good. I rarely use 3rd gear in my car. Under normal conditions it is 2 to 4.

If you don't like changing gears yourself, why get the manual at all?

Because 5th is too short for 65mph, and 6th is too short for 85mph. At least it is in my 2005 Z51.

I find it hard to believe anyone is seriously investing time and money into any more conventional gear boxes, especially a 7 speed.

GM needs to develop an electronic manual.

Did I say I do not like changing gears? NO. I said rowing 7 gears is starting to sound like work. It is a damn sports car, not a diesel big rig. Who cares what the frick 7th gear does for gas mileage on a freaking 500-600HP car???!!!!!!!!!!!!!!!!!!!!!

If they don't improve the ratios and just add a super cruiser gear on the top, why bother at all. Triple overdrive.

GM doesn't make the manual transmission. Tremec does, they have a lot invested in conventional manuals. No reason to not make a TR-6070.
What's the point of a 7 speed conventional gear box? Each time you have to push the clutch in, you stop acceleration. Watch any video of a Z06 racing a car with a dual clutch electronic shift transmission. Each time the Z06 shifts, it's like tapping the brakes for a split second, while the other car continues to accelerate.

I know who manufacturers our transmissions. But GM would be the one giving the specs to tremec of what they wanted.

It's not the distinctive new look I'd like to see in the C7. The japlopnik drawings remind me of a C6 that got a make over from the CTS-V team.

Cheers,

Totally different with an automatic. Push the gas and the car does the work. Do you really cruise for long range in a Corvette to need all those cruising gears? I guess if it keeps it out of the gas guzzler tax it may be worth just having them. As mentioned you don't need to use all 7. Just seems more complex and probably adds weight. I would think it also adds to the chance of a miss shift. Hopefully it will be gated.

I rarely use 6th gear now, because the car is not a dd. Even when on the highway, love the response I get in 5th, in 6th, kinda sluggish.

I get why the 7 speeds, to keep the feds happy, but it will not make me happy. When I make a discretionary purchase of a toy, the sole reason to do it IMHO, is to make ME happy.

I thought that I read somewhere that Euro automakers like Porsche were shortly doing away with all manuals? Now, someone here says Porsche is using a 7 speed in the new 911?

Trans is the same size. Weight gain is negligible.

Hell once it comes out, I'm going to see if I can do a swap into my car.
Maybe hi/lo will be next and we can go to 14.

Default C6 previews

Just to remind everyone that these so called spy renderings aren't all that accurate of the final car, below are drawings of what everyone claimed the C6 would look like.

What's important to note in all of the C6 predictors is how most of them got a lot of things right, or at least very close, and yet they don't look right at all. Small variances in shape or placement make the result ugly and unappealing compared to the real deal.

This is why I look at the Jalopnik illustrations and I don't freak out. Even if it's 95% correct, that last 5% makes the difference between gruesome and great.

Not accurate - agree; but 90% close

True, but I agree with Jinx. That last 5% - 10% is huge.
