WOW! This is funny! Over the years the 8 has had its power rating drop 3 times, 1 due to new sae standards. Now, after years of people claiming they don't get the mileage that the car claims we see another drop, this time in mpg. Is there anything else about this car that can drop...other than the resale value?

What I'd really like to know is, Did every car see similar drops in mpg or did certain cars go up, stayed the same or see bigger drops than others due to the new sae standard? Particularly, did the rotary drop more than others after real world driving was taken into affect based on reving it higher. Was the old test done at such lo revs as to obtain a not so real world mpg?

Did you test drive your car before you bought it?

Um... yeah...

ALL cars saw drops with the new SAE standards. Even hybrids.

And again ALL cars on that site will see a MPG drop because they are modifying their tests.

* Faster Speeds & Acceleration
* Air Conditioner Use
* Colder Outside Temperatures

The tests lower MPG estimates for most vehicles.

If you test drove it you shouldn't be bitching about the "power adjustments". It doesn't have any less power than the day you drove it. They could stamp mine with 10HP as long as it still drives the same.

First off you didn't answer my question! What does a test drive have to do with mpg?
And I only mentioned the many drops in ratings; power, mpg or otherwise was funny. I didn't BITCH about the power I only brought up the restating of ratings, so before you bitch you should fully comprehend what you read.

It is funny, because my car has not only not lost power, but it's gained it in significant quantities over the years

I think he meant to say that the actual mileage and power has not changed for this car, Doing even the slightest bit of research would have given you an accurate estimate on what you should expect for economy and power, regardless of the EPA tests (which as we all know, their testing methods were seriously flawed and did not accurately represent real world numbers)

On a side note, the numbers for my other car* have dropped:

As a result, I will be forced to sell it at a huge loss in order to regain an imaginary gain at the fuel pump.

I rarely get to stretch it legs for any length of time on the HWY but the city mileage seems spot on.

Makes me feel better. Now I don't have to worry that something is wrong with my car when I get only 16mpg.

If I'm right the RX8 gets the same mileage as a Z06.

I never said anything about MPG on your test drive. I was specifically addressing you bitching about the power ratings dropping.

And I posted that this is NOT Rx-8 specific and is INDUSTRY wide. And yes it did and still does seem that you where/are bitching.

Not only bitch, but bitching about things taken out of context.
