I think if your a track guy then its proven the M7 is the better choice.
But if your a quarter mile street guy such as my self then hands down the A8 wins. Its shown that quarter mile times are better with the A8. Unless like it's been mentioned you are a pro and super bad *** shifter which most of us aren't.

Do you guys think the A8 is better in the quarter mile than the A10? Does it work better gearing wise and require fewer shifts?

lgodom

The A10 should be the winner in the quarter. It has less closer ratios, thus less RPM drop between gears and stays so it stays in the power band better. Too bad it won't fit, or I'm sure they'd figure out a way to swap it over.

themonk

yes kinda....it has more to do with the torque than the bhp.

TOMZ07

I dont agree with thst statement. The A8 has less drop as it max out every gear to damn near redline get the most speed and hp from every gear which is the reason it over heats on the track. The A10 shifts out quicker. So that is not a correct statement. The A8 has put down 10.3 quarter mile stock. A8 quarter mile all day long

Every A10 gear up to its 8, cooresponding A8 gear 6 lose torque. And there's two extra filling gaps and adding torque too. It's easy math: IE 1st gear - (~45mph×650TQ)/~39=750TQ

The A8 shifts relatively fast, but, it is kind of weak, especially above 125 MPH, and relative to the M7 too.
The A10 is probably too much for the LT5 though! The LT4 tune is retarded now for this. It would be constantly up shifting for traction normal driving! The RR's being hammered and that linear power like the GT2 RS is that cure, but, that results in possibly more heat limiting, and excess engine wear!

And closer ratio gears, M7 included if possibly shifted as fast, means less drop!
Autos in general also have about 5% more driveline loss than a manual, but, computer control pays dividends especially in putting bigger power down!

• So GM dialing up the LT5 with the A8 for hot rodding and hot lapping numbers, but, heat limited (protects warranty)? The track setup or the standard setup are possible?
  
  
• A track rat M7 version of the above?
  
  
• A standard only version A8 or M7!

The real estate issue will be solved on the
Next model year -2020. That will give owners
That buy an a8 an excuse to upgrade and
Take a beating on their a8 trade in.

Mid-engine-DOHC SDI 6.2ltr-A10!

it better be half electric with this new Tesla that’s coming out.. 🙄

johnglenntwo

And it could be! Not the C7!

which is why I’m skipping this bolt on ZR1 and waiting for the c8’s 😎

crapthatsloud

As someone who dailys a Stingray with an A8, I am also surprised. I like it in the role I use it, but for the ZR1, I would think the 7MT would have been the obvious choice.

When my car is in "performance shift mode" its pretty snappy though....

I think if the A10 could be squeezed into the C7 platform, the ZR1 introduction would have been the perfect time to do it.

The C7 generation is winding down with an extended 2019 model year and all the R&D is going into the C8 and/or mid-engine or both so I don't expect any other major engineering changes to any of the C7s with the exception of the ZR1 addition to close out the C7. Whether the C7 platform extends through 2020 or 2021 is anyone's guess, but if it does, I don't expect any major changes.

LOL yes it is when you talk about the responsiveness between the two. More gears equal wider spread but less spread between then. Lower low moves the car easier IE more responsive,

JerriVette

I believe the LT5 has so much torque that the two extra gears of the A10 would be redundant.

The manual is a seven speed ..the automatic is an 8 speed...

Sure the A10 would have been the latest and greatest GM transmission but for the 18 months of expected production I think suggesting the A8 is unworthy...

I tend to prefer the M7 as a choice so wth do I know...but the A8 will be insane performance wise.

Those that order a ZR1 either manual seven speed or A8 are still getting the ultimate front engine corvette ever built...

Sure a dct would have Federer a little more responsiveness tooling around town or 7 tenths on mountain roads...but 9/10s the A8 kicks preverbial butt on all dct cars...

The corvette is never perfect...but what it offers is better all out performance than sports cars and supercars with names like ferraris, mclaren s, Lamborghini and Porsche..

A8 , A10 or M7

dbaker

IMO...I think they rushed it out to create excitement/orders.

Many were expecting the DOHC & A10.

I have an A8 in my 16 Z06. I don't really want the A10. I just want my A8 to shift like the A10 does in the ZL1 videos I've seen.
