CLEAN, how fast is highway driving for you? I've found that my truck (2005 5.3L 4L60E 3.23 245/70R17 tires, but with a mail-order 87 octane tune, muffler back exhaust and opened up intake), old rating 16/20, new rating 14/19) is close in city driving, but driving constant 50-60mph=21-24+mpg, 60-70mph=19-21mpg, 70-80mph=17-19mpg. Stop and go driving is what kills fuel economy. The time sitting at stop lights means no miles, but the engine idling is still using fuel.

 

just something i found interesting i was strolling the car lot today and checking out the new cars and on the sticker it would have the EPA rating for mileage then under it in smaller print it had the expected consumer mileage on all the new cars. the expected consumer mileage was about 5 mpg higher on most cars. so based off those cars im guessing the mileage will exceed the EPA rating

 

I have to wonder if that was done by the dealership or is that on all cars?

 

I saw it as well, it is like a 5 mpg range on either side of the official estimate.

 

But you are forgetting to include the change in tire diameter. The new car has larger tires, 28.66 inches (that's the number I have seen)as compared to 25.7 inches on the 4th gens. Based on those numbers the new cars should only be running about 50RPM higher at 70MPH.

Plus Scott has already pointed out to someone that the 5th gen WILL get better fuel economy than the 4th gens

 

I think considering that for 422hp, 23mpg is an amazing feat.
But Im sure that someone not driving it hard core, will be able to get 30mpg.

 

deepends on how its driven. here in cali the consistant flow of traffic on the freeway is 75-80 and about 70 for the slow drivers and 80-85 for the fast drivers.

The EPA estimates will probably fit right in here.

 

If the EPA estimates are right under those conditions then MPG flat sucks. I get about 26.5 to 27 MPG in my car at 75-80. That's with Cam, Supercharger and 4.30's

 

my friend can't get any better than 24-25mpg on his cam only. and that was going ~60.

maybe it's the cali gas , i get ~21 mpg here when most people get 25+ mpg on the net.

 

With a manual trans you determine the MPG. Drive the car hard around town showing off and wasting rubber in gears 1-4 all the time will get you 10-15 mpg. Drive like a person looking to avoid the gas pump and shifing higher and going easy when not racing the Camry next to you as the lane narrows and you should get much higher mpg.
This car should do just fine on the highway. Upper 20's shouldn't be a problem.

They should replace the torque guage with a MPG guage like BMW has so you can play with it.

 

I hope the 5th gen gets better mileage than my 95 Bird Convert with a 3.4
I get around 20 mpg average city/hwy driving. About 23 on the hwy and 18 city.
Granted I never have the top up so that could impact it. I only have 90K miles on it also. It has been this way ever since I had it. Guess I should have bought one with a V8.

 

my girlfriend has a 98 v6 camaro and gets the same exact milage. she's had the car forever and has always gotten that mileage.

 

Could also be that when I calculate my mileage I do it ONLY on a long trip consisting of almost exclusively highway driving, with the only stops being for gas, food, toll booths and the occasional traffic slowdown...

But my in town mileage is only about 15 if I stay out of the gas

 

Why don't people realize that EPA ratings are never going to mirror what they actually get? It's just a consistent test procedure that facilitates comparing one car's fuel economy to another.

There is no doubt in my mind that the EPA highway rating for the 5th gen SS with a stickshift will be at least 24mpg.

Side note: TTopJohn, for the 5th gen, the number of ratios in the transmission shouldn't be used to identify the transmission. All four available transmissions (6L50, 6L80, AY6, TR6060) have six speeds!

 

Yeah, I clarified that as "SS with the six speed manual" in the body of my post, just didn't feel like typing a longer thread title. And how about that transmission lineup? Even the "base" car is 6 speed across the board!

I found a chat transcript with one of the Camaro team members that said something to the effect of if you got x with your 4th gen, you will certainly be able to get x or better with a comparable 5th gen.
