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?
