I used to think this way. Now I'd much rather have cloth. It wears much better over time, and is much more comfortable in temperature extremes. I'll always pick cloth, if avaliable.
I have a 08 Vette with the A-6 and the Z-51 and I can tell you that torque managment takes over on a dead launch BIG time. I have even taken the car to LG Motorsport and had them take out as much as he could and yet if you stomp this car from a dead stop you can fell it BIG time hesitate!
As far as what Nine Ball said the paddle shifters ARE a joke they are slow and if you think they will speed up your time well be ready to be disapointed. Some of the Vette Guys think they are the bomb and they are fast, but most Vette drivers wouldnt know what fast is.
That being said my 08 A-6 Vette should run low low 12's as it is with a ram air kit and a tune it put down almost 400 rwhp and rwtq. In a 3300# car it is wicked fast. I have outrun a Viper and a run with a 505 RWHP Cobra till 120 when I walked away.

The whole idea GM had makes sense. If someone wants a new camaro for all out performance, they are getting the LS3 with a manual. If they will settle for an auto, they might as well equip it with DoD. You seriously won't notice it after a while. It is weird at first but you adjust your driving style to keep it in 4cyl mode.

Actually, the automatic is 3 tenths quicker from 0-60 and a tenth quicker in the quarter than the stick! Is this the first production car ever where the auto is quicker than the manual? Plus the L99 has variable valve technology, like VTEC + large V8. Hopefully the aftermarket tuners can exploit even more power with the variable valve technology.

Every time I read something about this car, I get more and more pissed off at GM.
It's bad enough the car tips the scales at over 3900 lbs for no good reason, but they stick the A6 with an L99 and AFM, all for a blisteringly pathetic 23 highway mpg? My car gets that with mixed driving, and it's running pig rich. Absolutely pathetic. I predict a HUGE bomb on our hands. GM just doesn't get it. AT ALL. They abandoned their fanbase to try to appeal to a bunch of people who would never buy a V8 with $4/gal gasoline to begin with
Absolutely not!
The Mustang weighs 400 lbs less with its heavy 3V mod motor. The Mustang is still a very large car, has a big, heavy engine, but weighs 400 lbs less and costs less money. Why can't GM do it? The LS3 is very light and compact for its size. There is NO excuse for this ridiculous weight and HUGE body size. If I wanted to drive something big and heavy shaped like a brick that gets terrible gas mileage, I'd buy a Trailblazer.
This thing weighs as much as a damn GT500 with its HUGE mod motor, heavy drivetrain and supercharger. It's embarrassing. The only difference is the GT500 would destroy this car in a race bone stock, is much more easily modified for a lot less money, much more responsive to those mods and will probably not cost a whole lot more. ARGH!

I have a 2009 pontiac g8 gxp with the automatic... i get the ls3 with the a6
no l99 here.. but there is a 1700.00 gas tax...lol another thing is the crazyness on the g8 board to get the m6 for the gxp... but with the a6 and ls3, i stomped a m6 gxp ,"they have the 3.70 rear gear".. all the way to 120 and he was behind me still... the first gear in the a6 at 4.03 and the 3.27 rear gear is a beast. really pulled on the m6 gxp hard in first, we raced from a roll 5-10mph, i had my shifter in manual 1 , when i nailed it,not much bogging at all, i quickly shifted left then right to be in sport mode.
Does seem crazy that the camaro with the auto gets the l99.. and the g8 gxp gets the full ls3 the weight differance is really not that much 100-200lbs... so all you m6 camaro ss guys with the 3.43 gearing had better watch out for a auto or manual gxp. Better hope you dont have a passenger or you will see a 4-door sedan slowly walk away

The biggest advantage for the L99 is VVT. Wait until you see how much power can be made with little to know loss of low end performance. There was a great article in GMHTP awhile ago about Comp Cams and there research on I think the L76 V8. They were getting up to 69RRWHP without giving up perfromance anywhere. This isn't possible without VVT. I can't wait to see what they do for the L99.
ok this thread was resurrected...so I'm chiming in...
GN is bad ****...I have one and love it.
my 2010 SS/RS is a L99 car...L99 is an LS3 just with the whole V-4 afm going on. some ls7 lifters a tune and new cam and you are an ls3.
I'm beta testing mine with Hypertech right now and one of the most interesting things I've learned is when the afm/v4 is disabled, you only drop 1-2 mpg on my car at 75mph on cruise control.

On the phone? well the l99 puts out less horespower but i did think that they were just as fast. i wish i could just get the ls3 with the auto but doesnt look like that will happen. ive driven a manual and automatic and i get tired of shifting gears all the time ecspecially when im on the phone
