does the LS3 have Active Fuel Management? (Manual Trans) - Page 2 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Manuels always get better gas mileage than auto. Look at the corvette base model. same engine? yes. rated at 26 mpg on highway. thats what really changed my decision on the auto. originally I had the auto, but naw man, it want look right with that big engine.
ordered 10-20-08 black ss hurst short throw, sunroof (so the gals can hang out)

Get the manual and drive economically when not out to tear up the town. You can very easily get great mileage out of just about any engine with a manual transmission.

just read about the new g8 gxp manual, and the best highway mpg was 20 mpg.

its like driving a new full size truck.

expect the same for the camaro.

No. The camaro is smaller, lighter, and geared differently than the GXP. It should give you 23 mpg on the highway in with either the LS3 or L99

Yeah.. I am SO D@MN happy that it won't have the gas guzzler tax.. After hearing my dealer tell me the L99 won't be gas guzzler taxed I about wet myself from excitement.

wow. ok thanks for all the feedback. i guess i apologize for the newness

??? but again thanks for helpin a guy out

If it is anything like my 1998 M6 LS1, I hope to get 25 MPG+ out on the open road, with minimal stops and cruising at about 70MPH.

I think the 23MPG is a little underrated especially since the gearing is very close to my 1998 (I believe the LS3 cars have about a .57 6th gear and about a 3.45 rear end gear ratio). I can get ~27-28 MPG cruising at 70 MPH.

For what its worth I am able to cruise in my 1998 at 80 MPH at a LITTLE less than 2000 RPM.

I know the 5th Gen is a little heavier, but weight is really only applicable when accelerating, where as aerodynamics are more important at constant highway speeds...The C5 Corvettes were able to get 30-31 MPG with the LS1 because they slid through the air. So a good comparison would be a LS3 manual C6 Vette and subtract around 4-5 MPG assuming the drag coefficient of the 5th Gen isn't worse than the 4th Gen.

Now, I don't know how much of a difference the 6.2L LS3 vs. my 5.7 LS1 will make, but these cars just loaf along on the highway.

can someone please explain the gas guzzler tax to me. how is it applied?

Tal · 02-11-2009, 05:16 PM

Click the search button, type in 'gas guzzler tax' and hit go. Several of the threads that you find should answer your questions, at least check the one about halfway down the list that is specifically labeled gas guzzler tax. I'll answer this much of your question right here though; if a car has the gas guzzler tax (the Camaro won't) the tax is applied to the purchase price, think of it as a federal sales tax.

i thought the ls3 (manual) averaged less than 23 mpg. look at the g8 gxp

Tal · 02-11-2009, 11:32 PM

Slightly lighter and different gearing, and most importantly Fbodfather has stated they will avoid the gas guzzler tax. The formulas from the other thread are only estimations and cars with slightly worse mpg have avoided the tax, like the G8 GT and its 15/24 rating avoiding the gas guzzler, and with that accomplished I am confident GM can do the same with the L99 Camaro. The GXP numbers are a little concerning for the manual LS3 Camaro but there are enough differences such as it's crazy tall 0.57 sixth gear make the idea of the Camaro SS avoiding the guzzler tax realistic. Beyond that we are all just waiting on the official numbers to be released.

I agree. The GXP probably has better aerodynamics as well, but is probably a wash when gearing is considered. It does weigh ~100 lbs more though. Maybe 21-22 mpg highway. I haven't read ANYWHERE from chevy stating that the manual will get 23 mpg.

*Mr. Wyndham* · 02-12-2009, 12:28 AM

They stated 'unofficially' (

), that the LS3 would get 22mpg, and the L99 would get 23 hwy. In any event, there's no gas-guzzler tax....and we all know the "real world stories" of GM's LS engines...Corvettes getting 30mpg hwy regularly....

I am interested in why you might think the GXP has better aerodynamics than the Camaro...I would tend to think the opposite...

Tal · 02-12-2009, 12:50 AM

They do the testing in a lab and so they adjust the dynamometer to simulate wind resistance, but my understanding is that actual aerodynamics aren't accounted for anyways.
