Wooo Hooo!!!! I have the same drivetrain so I just jumped to 41%.

On my old SC2 and this SW2, before I joined GasSavers, I got a consistent 30+ combined MPG, so I was already 13% over EPA .

Many thanks to all the leadfoots out there for making us look good !!!!!!!

The hybrid modifier is larger. The 05 Prius dropped ~13% too.

The new numbers were very close to what I saw without trying. If they are more accurate then it is reasonable to make an adjustment. Any arguments regarding how much gas is currently being wasted just got a boost.

I thought that, driven carefully yet not doing any extreme hypermiling, the estimates were darn near exactly what could be obtained in the real world.

I agree. Kinda of take the driver out of the equation.

Next time you're driving and the car behind flashes his light come around hard and slams on the brakes at the next light just think to yourself. Hey he's what the epa estimates are based on now.

My percentage above EPA just rose dramatically.

22/24/28 to 19/22/26

Mine car went from

31/34/39 to 26/30/35

Does this mean I should change the EPA of my car in the garage?

I think this will become a new debate.

Here is what I want from Matt (I know, all gimme gimme gimme) :

In the Garage, there should be a new checkbox that says "New EPA MPG Figures". If the user checks this box, then the user is inputing new EPA values. Otherwise, the assumption by Matt is that the input is old EPA values.

Now, here is the hard part for Matt. Based on the user input, Matt needs to extrapolate the MPG of the *other* EPA value. Why? Because the argument could be made that older cars should have their EPA figures based on how the cars were originally tested because the original EPA figure is based on a *real* test, not a "rigorous guess".

This would create a two-tier Hypermiler display that could look like the following :

EXAMPLE BASED ON OLD EPA FIGURES


EXAMPLE BASED ON NEW EPA FIGURES


Both would be displayed in the garage, and the user could decide which one to display.

This is just a suggestion, mind you, .

"I thought that, driven carefully yet not doing any extreme hypermiling, the estimates were darn near exactly what could be obtained in the real world."

I agree. For the first few years I owned this car my driving habits were normal. I didn't try to save gas, I just drove any way I felt like driving. I would typically get about 24mpg that way, which is exactly the same as the old EPA combined est.

OTOH I like how much farther above EPA estimates I am now. I gained 15 percentage points overnight!

So.......... what are we going to do? go with the new figures?

Maybe we need to have a vote on changing or not changing to the new EPA figures? I am not sure how I feel about this.
