True, once you get past 50mph or so. But acceleration off the line to 60 mostly occurs under that speed, and that's what was in my mind when I answered.

I like to think its the gear spacing being wider on the manual trans working better with the Turbo motor power band .

The 10 peed trans can be a great thing for the right engine like a E92 s65 motor that only make 300 FT. torque and max power at 8,000 RPM. The LT4 is making 400ft. of torque at a 1,000 rpm its making 500ft. torque of at 2,000 up to it max 600+ ft. torque that engine is never out of its power band . For the car to be able to use that I think the car is going to need wider gearing spacing to be able to use the torque the motor has to make the car go faster with out blowing the tire off the car or the car just going to pull power to hook the car up . If the car is pulling power to hook the car up than what the point. The only time you really be able to use it is at speed over 150 MPH. So how many road course that you can really run a 150 MPH+ on.

Let me make this clear I am not nocking the 10 speed trans, I just think the LT4 engine is not a good match for that trans.

Hole point of the Z/28 part is that you have to be able to put power down on corner exit to run fast lap times . That is why the new 2017 GS corvette with only 450 HP & 450 ft. torque ran only .6 off the ZR1 lap time ( so say GM) . That tells me the C7 corvette chassis can really can only handle the LT1 motor and that car is running a P325 cup2 tire on the back of it. The new ZL1 is only going to have a P305 on the back and a motor with 640 HP & 600ft + torque and you are pack 10 gears in the trans together with it . Now its just me thinking here I don't see how the car not pulling power every time you go WOT under 100 MPH.

Seems to put the power down pretty well off the line....and my butt-dyno agrees.

Don't forget the PTM system (best in the Industry), and the ELSD. Together with very short gear spacing, the LT4 can generate higher power levels (at lower torque in the upper rpm range) for a longer period of time, while the electronics put it to the ground at any point in the corner.

As for powerband, we haven't seen the gear ratios or axle ratio yet.

It's possible we have a 7th, 8th, 9th and 10th overdrives. Who knows.

But be sure GM isn't going to put a transmission in this car that doesn't work well. I'm convinced of that.

I've never been a fan of Camaro's tap shift. In fact it's garbage in the 5th Gen, but that 10 speed is awesome. Still a little much turning the wheel and having to tap on a road track, but I think I could get used to it.

It used to be that all the race-y Euro cars that had it used column-mounted shift paddles...but the more TopGear I watch...the more cars seem to be using wheel-mounted paddles. They're just...bigger.

[Jeb114]

We purchased a Jeep for my wife with a 9 speed auto trans. It is the most annoying car I ever drove. Go down a street at 35mph, the trans shifts up and down so many times I have to put the shift in manual mode to stop it. There is a big uproar in the jeep community about it. New software upgrade just came out, just changed the annoying speed to 50mph.

The HouZe has a new Z to discuss.

There ya go...now that looks like a wing!

[Mr. Wyndham]

That's a big spoiler/wing.....

And the tires don't look terribly aggressive...are those snows?

Hmmmmm.....

Despite the bigger rear wing, the front end looks just like the ZL1, without a more aggressive front splitter...and the now-familiar inverted trapezoidal gaping-maw grille...with all the aerodynamic work that went into the ZL1's face for cooling, it would make sense to re-use the results for a track-focused model.

So....what do we think?

Track kit for the ZL1?
New N/A engine for the Z/28?
Light-weighted ZL1?
Light-weighted SS?

Or a practical joke, like those stickers on the ZL1 prototypes?

Some rumor information (of course, that's all it is) supposedly states the first 6 gears are underdrive, 7th is 1:1, and 8-10 are overdrive.

Hopefully they've got the calibration right for the road...maybe skipping gears?

What do I think? I don't know yet. I never thought we would see another hi po Camaro this soon. I doubt its a track pack for the ZL1, or a practical joke.

What do I hope? High revving n/a small block around 530 hp, lighter weight, big brakes and aero. I hope this car takes what the previous Z/28 did, pushes the bar forward and does it cheaper.

GM is doing performance better than any mainstream brand in the world right now. The only thing I feel they are missing is an n/a, track focused car that decimates the competition. This is what I hope from the Z/28.

That would be a major concern to me. Almost makes me want to wait before I buy.

[90503]

Automatics are a big mystery to me....They seem to have been bullet-proof and worked well over the years for drag-racing....Road racing, not so much with American cars....too heavy....harder on brakes....etc....

Regardless of any of that, my question is why is this ten speed making it's debut in a Camaro?.....No year or two first in the Corvette?....or Cadillac first?....Is the Camaro the new guinea pig for the other lines?....

We've seen this trans at one track for a quick public relations, release story....I still would have my doubts it's a greatest thing for regular track duty as the first new automatic transmission seen in a Camaro....

[2SSRS@Gen5diy]

To me the A10 has to small components for the power we are going to put down, for drag racing, will see how long it lives with 100 pass on it.

[zcarczar]

The A10 was co-developed with Ford and is going into the new Raptor, which if it means anything I've absolutely destroyed transmissions in my off road car where they would hold up perfectly fine in a street oriented race car running the same horsepower. Granted the new ZL1 does have considerably more horsepower than a Raptor, the Raptor is quite a bit heavier and off road use does place some pretty considerable shock loads on the drivetrain when traveling at high rates of speed. I wouldn't be too worried about it holding up.
