No 3 pedal manual? Travesty...... :thud:

 

It's not hard to see why the C8 won't have a manual trans option. With more and more C7 owners selecting the 8-spd Auto, it's becoming impossible to make a solid business case to keep offering it.

I personally prefer rowing my own gears, but DCTs are definitely faster and way more convenient to daily drive.

I agree with Nick. I do like shifting. Just my preference. I didn't like the Ferrari that I drove with paddle shift.

That being said, I've never had to daily drive a paddle shift car. Perhaps I'd like it just as much as a traditional manual. Dunno...until I have a C8 in my garage.

 

For a weekend car, it makes it that much more special to be able to row your own gears.

However, I do enjoy the paddles on certain cars. My dad has an E92 M3 with the DCT Trans, and I'd definitely take that over the 6-spd in that car. It's also .02 tenths quicker to 60 IIRC

I'd have to have a manual if I had a C7, even if it was a tad bit slower

I've ridden in a Porsche GT3 with their version of clutch-less manual and the shifts are "right now" no question. However, letting it do its own thing - driving it like an Auto without manually choosing gears - looks like a new skill to be developed that involves the driver's communication to the systems via the right foot mostly.

That said, we don't know if the new Tremec tranny will be controlled by a system with a "fully" auto mode or not. Could be handy when you are caught in a freeway stop and go situation.

Every daily driver I've had since I go my license - yes they had cars back then, and mine was a '55 Chevy 265 CI V8, 3 spd OD - has had a manual tranny. However, progress is progress and I'd be willing to let my left leg muscles atrophy to get the quickest shift possible.

 

This transmission isn't a transaxle like you have with rear mid (going based on the picture of the transmission). I don't know if Tremec has developed a transaxle version of their transmission or not. The type of transaxle that the Corvette uses isn't the same form fact that you would typically see on a rear mid engine layout car.

In its current form (both the TR-7007 and TR-9007) would work in front engine RWD cars and adapted like other Tremec manual transmissions could be placed in a C7 Corvette. Though the C8 is going to need a transaxle regardless, so if they are going to spend the money it would make sense to produce a DCT and only a DCT for it.

So i can see the C7 Corvette picking up this transmission, and I can see the rumored ZR1 C7 picking this transmission up as well.

 

Roadkillz - Maybe you are right. Maybe all the blogs and magazines are wrong. I'm just reporting what they are saying here.

But then, you've been wrong before. You insisted the C7 would be as much as 300 lbs lighter than the C6. Neither of us expected it to be heavier than the C6.

We don't even know the layout of the rear mid yet. Although not likely, they could even try the transverse layout again. Regardless, they have an innovative team so we'll just have to wait and see what trannie they use and how they place it.

 

My guesstimate was partly wishful thinking on mass and based on all of the marketing they gave about light weighting.... . No one outside of the engineering team expected a heavier weight, really a lesson in marketing... when you are developing a heavier car do not produce so much marketing about weight reduction. The Camaro team did a lot of marketing about weight reduction and they produced a car that in its base trim is 3,339 pounds in its lightest trim (from a 3,700 V-6 Camaro in its previous generation).

Blogs and magazines are not reliable sources of future product development, not because they don't get good information but because they put out so much and contradictory information as well. Not only that but they sometimes leak information based on development choices not yet made, concrete such as V-8 vs TT V-6. Remember it was reported that the C7 would have a 5.5L V-8 engine, it was also reported that the C7 would have a TT V-6 engine as well.

conventionally rear mid layout vehicles use a transaxle designed like this...

The Porsche 911 uses the same type which is what is pictured just flipped around, the big flat end attaches to the engine and the circle spots is where the half shafts mate up at which is inline with (or really close to) the center of the rear wheels. Porsche transaxles are often mated to LS motors in rear/mid kit cars, if they used a similar trans axle layout as in the current car it would push the engine forward. They could get a similar moment of polar eneritia as in a Chevy Cheetah though you end up with not enough space for passengers.

Hence unless they go with a transversely mounted engine layout they are going to go with a traditional transaxle (no innovations needed).

There is going to be a purpose built transaxle for this car, it won't be shared with any mass market vehicle at GM. It is going to be dumb not to produce a DCT in this situation as no matter what they use it will be a new design (or purchased from another company). There is a serious posibility that we may not see a traditional manual transmission in the car at all as they could reduce cost by only offering the one transmission as well as making the design more simple.

 

Interesting Reading & Developments.
The 664 + Ft/lbs input torque capacity seems impressive.
But Guys are definite going to Twin Turbo Charge the New C8. Its real easy to obtain 1,000 - 1,600 ft/lbs of torque on Boost.
High Boost will push to over 2,000 Hp levels at the crankshaft.
Turbo charging creates HUGE ENGINE FLYWHEEL TORQUE.

The C8 will have to compete with Lamborghini stock vs stock & On Boost at over 2,000 HP.
