Not a problem my friend, I just remember that one because I shared your hope for AFM and a manual, not to mention flex fuel like on the Tahoe version of the motor, that would have been extremely cool, but upgrades will come with future models....

I guess it makes sense with small jerking of the car when activated/deactivated, but I could live with it

I think I could squeeze 25-27 out of the LS3 which is better than the 23 as projected by whatever website I just read. LS1 and 2 owners say they can get 28+ sometimes. Obviously the first week I own the car i'll be getting around 6mpg

I am with you on that. I beat the EPA rating on my Cobalt SS/SC by 3-4 mpg by driving like someone heading to their own funeral...I save up the gas for the occasional mad rush or drive on my favorite twisty road....

With the AFM or cylinder deactivation, whatever you want to call it, is it any harder to mod the engine? Or is it almost exactly the same as with a LS3 with the manual?

You'll have issues primarily with the cam There's a reason that AFM-equipped engines are slightly less powerful than their 'normal' counterparts. The special lifters installed for the system require a lower-lift cam profile; that doesn't allow for a lot of wiggle room as far as cam-swapping.

I've read somewhere (forget where) that both the L99 and LS3 will require Premium gas. What are the odds of this being true? The Camaro has never required Premuim in the past that I remember.

I see the LS3 in the Vette is 'Recommended' Premium. If they 'Recommend' Premium I can deal with that. I'll just alternate between the two every so often...

They are marketing the camaro as
"2010 Camaro:
Fun, Efficient Sports Car For The 21st Century"

I HIGHLY doubt that they would require premium gas in an efficient car. And with gas the way it is now there is no way they would do that.

Required...according to car mags/sites. Because using regular would result in an unacceptable power drop.......

You're LS3 observation is a good one.

I'm not saying anything...

But if I were to bet, I'd place money that it recommends premium for optimum performance, but just like the Vette and G8; it'll run fine on regular.

That sounds like a logical explanation. I think the L99 people are thinking of is the old 4.3 V8. No way in the world is GM going to use a 20 year old engine, no matter how many refinements and upgrades they make to it.

Darn, i really want a V8 automatic that i can have fun with and mod just as easily as the LS3. I guess I will have to wait for a few days for the official release when the facts come out until I have to think about a different engine or trans.

I always encourage people to learn how to drive stick, and those that do, I never let them use the excuse "it's such a pain in trafic" when they are buying a car like the Camaro.

Learn stick, buy stick. Keep clutch manufacturers happy!

Personally, if I wanted an auto, I would want the same V8 that comes with the manual to be an option. There's talk that the autos will come with the L99 and the manuals will come with the LS3. I wouldn't be too fond of this if the LS3 wasn't also an option for the auto. I can understand an auto only model that comes with the L99, but I would still want the LS3 as an option for the auto because I want the same power. Does anyone else feel the same?

It APPEARS the L99 is the L3 with AFM, etc, its a 6.2, but it has been rumored for quite some time that there would be a hp difference between the auto and the stick..I hear what you are saying, we should know a great deal more tommorrow

Well generally autos produce less power(rwhp) than manuals outright, so if I'm wanting an auto, I don't want to be restricted to buying an already less powerful engine. Hopefully I'll find out tomorrow.

Honda follows this same principle. The Accord sedan and coupe with 5 speed automatics have the 3.5 V6 with AFM. On the Accord coupe, you can get a 6 speed manual, but you do not get AFM on the engine.

You cannot buy an automatic V6 without AFM. I will presume the same will be true for the Camaro L99 and LS3. I think the main reason for that is computer programing - they would need TWO ECMs for the automatic SSs, one for AFM and one without. That would increase production costs and decrease CAFE averages.

That's what has me puzzled. If the story is to be believed it said that the V-8 auto would be the L99 w/395 hp w/AFM and that the standard would be getting the LS3 w/420 horses a 25 horse difference, now if it is the same engine why the huge gap in horses? Now the challenger R/T for example has 370hp for the auto w/MSD and 375hp w/o MSD for the standard just a five horse difference.
Now me personally it don't matter the L99'd still kick the R/T's butt anyways and barring some huge screwup like priceing the Camaro through the Roof I'm getting this car.

I don't understand the huge gap between the manual and auto either if the numbers are correct.. Anyone care to explain??

On the fuel front, my 2005 Monaro with an LS2 requires "premium" (that's 97RON here but I know the format is different to yours in the US) due to the compression ratio - making it cleaner but less easily supercharged/turbocharged.

The LS3 is no different (think it's 11:1) so I would fully expect the Camaro to need higher-octane fuel.
