Not much would be good, other than having the option of being in either one...

...Like it or not, it seems AFM is here to stay...and if it is, and can be capable of significantly better mileage, it might help keep around the availablility of V-8's that don't have AFM...

Everybody keeps thinking of an engine from the 3rd Gen Camaro called the Iron Duke (2.4 liter?) and that's what this newer gen I-4 turbo Camaro would end up being like.

Yu mean its bad to have your cake and eat it too? I'd love to be able to get 35mpg on my 2010 by it using 4 cyl and when I want to play with the power, I have it. I mean why burn fuel on a trip when you dont have to?

...But...my gosh...when I shopped for my '11, the L99s with AFM were rated at "1" mpg hwy mileage greater than the manual trans cars..."ONE!"...I could see AFM being the greatest thing since a pocket in a shirt if the mileage gains were vastly greater than those without AFM...

Just seems like a ton of technology and what-not for very little gain in mpg...on top of what is perceived as driving a "performance" car on four cylinders...dunno...
I know back in the day, manual trans cars would get better mileage with the same motor. So maybe an Automatic LS3 would get 2-3 mpg less then a manual LS3 so the increase of 1 mpg over the ls3 manual may be 3-4mpg ls3 auto vs l99 auto... Make sense?

Might be getting close to what you mention, if it's true about the 2014 Stingray having that option...No idea how it's actually done, or what mileage gains there would be, but sounds like a good idea...
Now I understood the LT1 dod/afm on/off was turning on/off the ability for it to go into 4 cylinder mode.

example:
dod off (always V8)
dod on (just like L99 cars, the ability to go into 4 cylinder mode)

I agree with you that manuals have traditionally gotten better mileage than autos...and you are probably correct that the AFM enables the autos to keep close, or better...but 1mpg for highway mileage rating better with the automatic than the manual....seems like it should be much higher than that...

....Good info....then if AFM is also used on manuals, their mpg should be significantly greater than the automatics again, as you state above...

EDIT...screwed up the quote thing...lol...replied to the first part in your quote...sorry...lol

This^^ plus its not about wanting a 4cyl camaro. I never want that as an option. Its about being able to have the option and ensuring that we can always have a V8 in our cars 10 years from now with crap like CAFE inhibiting our enthusiast crowd. The better the gas mileage a V8 camaro can get, means the more V8's they can sell across the fleet which keeps that rumble in my car!

I'm all about fuel management. I just didn't want an automatic as an option when I bought my SS. My AFM is me not putting my foot in it every time I am on the road. In actuality, I am probably more gingerly with my SS than I am with my EVO. Reason being, I like the cruise effect and to hear and feel the rumble that only a V-8 can give me.

I didn't say that it was bad. It's just all personal preference. I don't think the majority of us have our foot all in the floor whenever we take out our Camaros. We all know a foot in the floor will end up with more fuel demanded to keep up with the foot:D

I think we all want better gas mileage, regardless of AFM. If they are doing it to appease the US Govt, then so be it.

I don't think preference has anything to do with it. Everyone who owns a V-8 would love to to take a trip on vacation in their cars on 4cyl and then when they get to their destinations, turn on all 8. Or if its your DD on wkends, it's an 8cyl. During the week it's a 4. It's not like it'd replace the 4 or 6cyl because you're deactivating cylinders. Lol. That's preference. By choosing to save gas ALL the time.

I agree that AFM/DOD is here to stay on larger displacement engines, and I think it will get better over time. However, I think GM will probably introduce some 5.0-5.7 L engines that don't have AFM/DOD at some point. If the power is there, a lot of people will opt for those instead of the larger displacement versions just to get away from AFM/DOD. Just my opinion.

I'd say if the LT1 is the Gen6 SS V-8 engine, then definitely an up-grade with more hp and torq...

....If it has AFM on all models, but we have the ability to drive without it, as an "option" of our choice, then that also is a good up-grade...

....If AFM adds better mileage to the V-8s, manual or auto...another good "option" if you "choose" to drive in that mode....

Could very well be....It seems the AFM engines are somewhat limited, or more problematic when it comes to aftermarket super-charging or turbo-charging with the different valve/rockers, whatever compared to the LS3...(Nothing but love for L99ers...lol...just from what I've seen around here...LS3 "conversions" prior to forced induction)...

Perhaps the 5.0-5.7 engine (LT-4??) may fill that void and satisfy more aftermarket applications...A second V-8 engine option of any kind would be totally awesome, imo...

The fact that GM introduced the Gen V LT1 at 6.2L would likely mean they won't be offering a lower displacement performance V8’s, this generation.

There wouldn't be a business case to develop a smaller displacement performance V8 purely to circumvent their AFM/DOD technology.

Lots of speculation as to what the higher performance variations of the LT1 will be but it's not likely to be any less displacement than the 6.2L.

GM is in the business of building cars and trucks for profit. Not in the business of supplying street cars with engines capable of big aftermarket HP. Despite what we enthusiasts want.

I agreee but disagree also. If they produce a car that takes kindly to after market enhancing, one might be more apt to purchase it over another less modifyable car.
