35 MPG for V-6?

[MrIcky]

I don't know about the imperial gallons thing.

As far as cruising down the road and looking at the instant mileage on the DIC, ya people are probably hitting 32 in a V6. If you go straight from a gas station on the onramp to the freeway and hit cruise with no congestion- ya maybe.

Pretty optimistic expectation for overall daily driving though.

29 is the revised EPA testing that recently came out to simulate real worl. You should be able to tweak out better than that if you don't lead foot it.

Correct. In the URL there's a PVC code. Changing that will give you different values. Here's the correct values... http://www.camaro5.com/forums/showth...790#post461790

Of course you can get better MPG than advertised, in many different highway driving conditions, but ratings are based on averages generally. Upslope, downslope, tail wind, ethanol, and even temperature, humidity and barometric pressure can also effect the net result on each vehicle.

Does rim size factor? Maybe the LS gets better mpg? Higher octane?

It's not hard to beat the new EPA ratings at all. They've really lowered the bar. I bet in the Camaro you can just keep the RPM low, enjoy the torque, and beat the EPA.

I tested this extensively, and unless I was going downhill, I didn't go above 28. This is with automatic, AC off.

edit: and not counting acceleration at the beginning.

There's a thread on here where someone received their car "canadian" and it's window sticker for a V-6 showed 35mpg highway....theirs is rated a little differently.

exactly thats one of the nice things about the new EPA standards, they actually made the tests so the real world fuel economy is the same as the tests

[MrIcky]

I thought they raised the bar? i.e. epa ratings were made lower where they used to be really optimistic.

They also don't test based on ideal driving conditions. Basically, the test is unfair, and that makes it highly probable that people are reporting higher fuel estimates.

Yes, the ratings were made lower so they're easier to achieve by real drivers in real traffic. I said they lowered the bar, meaning the difficulty level for drivers to get the same results. You are probably thinking they raised the bar meaning the effort they put into simulating real usage.

If you look at a window sticker from 2007 and look up the same car on fueleconomy.gov now, you'll see that the car is expected to get fewer MPG by the new math.

2007 Impala 3.5L V6 auto:
Old test - 21 city, 31 highway
New test - 18 city, 28 highway

For cars that were rated before the new test procedure was put in place, they calculate what it would be.

The new test is based on normal common conditions. It's done in a lab on a dyno, but with procedures to simulate the way people actually use the car. They test with the air conditioner on, at and over 70mph, etc.
