good lookin out.

starting with 08 models, that's what your gonna be seeing on every car. And yes it is closer to the actual milage.

16 - 22
Yea, I believe that. I get around 17 mpg avg, but I have a lead foot.

Aston Martin DB9 only got 13 avg.

mustang gt got a 16 (14 city& 20 high) w

edit: sorry that one is supercharged the normal one is 18 (15 23)

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.

What does a test drive have to do with mpg.? And, yeah I test drove it, and fell in love with it.

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.

that sounds pretty close, I usually get better city mileag though

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.


*imaginary car.

Since I'm from Canada we use L/100km's...so mine actually went UP!!!

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.

my 4 year average is 20mpg in my RX8 -shrug-

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

interesting...want better economy watch the RPMs

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

And I asked you what does a test drive have to do with mpg and you didn't answer the question, and how is my bringing up the power rating drops in conjunction with the mpg ratings drop bitching?

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.

yea thats about right for me..

You would think the 350z would get better than 20mpg average.

sounds about right. when i mix i get 18-19.

i like the new rating, bumps down those damn prius'

Why would you think that? The power those motors make isnt free. And the cars are bloated pigs.

I get 12L/100km on average ... which works out to be 19mpg ...

... I have been able to tip 9.7L/100k before which is more like 19.5mpg, if no 20mpg.

Sorry if my calculations are incorrect, I just worked it out in my head.

FINALLY - R.I.P. to all the frustrated MPG wining posts. As if it meant anything - now practically anyone will get the "official government mileage". Yea!!!

you can double check here...

http://www.calculateme.com/cGasMilea...100kmtoMPG.htm

9.7L/100Km is about 24mpg.

Cool site I didn't know the RX-8 had a 2 cylinder engine!

The page for the MX-5 is dead on though. The New EPA MPG is exactly what I have had so far in the 2007 MX-5 6M: Low of 21, high of 28, average of 24

OOoooooo BURRRRRRRRRRRRNNNNNNNNN! :rofl:

there's something i love about this car's faults. cant beat a camaro off the line? ok. crap-ass gas mileage? so what? reliability is shit? thanks for the warning! for every bonehead in a hot-shit "i have the loudest fastest ride EVER!" muscle-car douchebag, we have an 8 owner that knows the limitations of their car, and drives it/loves it REGARDLESS.

seeing "official" numbers makes me feel better, too. I average 16.5ish mpg city/hwy, and when i think im getting STELLAR mileage from a long highway trip, its at 17 and change. i never thought i'd see 20mpg, and uh... now i dont care!

FANTASTIC ! ! !

I HAVE FINALLY GOTTEN THE EPA HIGHWAY ESTIMATE ON MY FAITHFUL "04.

On my last run from Houston to Gulfport, I exercised remarkable (and boring!) restraint, held her to under 75, and measured 23.4 mpg. I was dreading having to slow her down even more on the next trip, but no---

I've finally seen her get the EPA estimate.

Drove just last week with three other RX-8s from Chicago to Michigan at about 85mph consistently...we all averaged 23-24mpg.

hmm, see I thought the old ratings were correct, as even on winter gas I was getting around 20-21 in mixed hard driving.

Oh well, now everyone will be happy when they get better than the EPA ratings

You all get better mpg than I do so quit bitchin.

LOL, I'm the 2nd one on the list...the FL guy with a lifetime average of 19.2mpg in stop and go driving, while not stuck in traffic that much at all.

Since then, I'm now driving like 70% highway and 30% highway and I'm getting like 21mpg. In my opinion the RX8 driving softly in the city in moderate traffic can hit 19mpg (flat land, and base 6spd) but normally I hit (with a lead foot that grows heavier every year) about 18.8mpg but here is my complaint.

There is NO WAY I've ever even come close to the 24mpg highway, the best I've done is about 21mpg and while I've never been on the highway at 75mph for a full tank I just don't see my 8 getting 24mpg honestly.

Just a finished a tank and got 16.89 MPG.

I seriously think i'm selling my 8

Starting a deep frying Fish and Chips place

Buying TDI Golf/Jetta, Diesel Chevy and going SVO Alternative fuel baby. That's how i'm running into this shit. I just can't stand it anymore.

Replace the RX8 with a LGT Limited and figure out how to make it do E50 or E85, since guys do it on the imprezas.

The new numbers bring down the highway a bit too much, but the city is probably closer to realistic.

I'm only getting 13mpg in suburban driving, but I only drive about 6 miles to/from work each day. Getting the car to operating temp must be a big part of that crappy mileage. However, I've gotten 22mpg on the highway doing 75-80mph. I'm sure I could do 24-25mpg if I slowed down to 65mph.

Shift points are also probably a big key in gas mileage. I read in other posts about what gear to use at 25mph, if I'm not trying to pass I'm up shifting quickly and will skip 2 or 3 gears most of the time - 1st, 2nd, 4th or 1st, 2nd, 3rd, 5th and now I'll do 1st, 3rd, 6th.

I wonder if a hybrid version of the RX8 would make sense. The electric motor would help in low-end torque and improve the terrible city gas mileage.

AND THE TRUTH....SHALL SET YOU FREE!!!

I get better than the new EPA estimates in both city and highway. My actual mileage is about halfway between the old and the new estimates.

I don't know how some of you possibly got 23 or 24 miles per gallon, even only on the highway and only using cruise control, but I managed to get 20 mpg on my tank last week. I live a mile from the highway and it was pretty much all highway. Ramathorne is always all highway. But I was so happy about seeing that big 20 I had to call my buddy with a v6 accord coupe. He then he put me in my place with his 24 mpg. Whatever, he drives an black egg.

After more than 100'000 km with the car (daily driving, 25% city, 75 % jammed autobahn) I'd say the average mileage is 19.5 mpg. You can get slightly better results if you really try (I managed 23.5 under above circumstances) and of course much worse (9.5 is possible if you race the car full force).

Your not driving fast enough if you only get 9.5 MPG on the track.

I don't drive track - I drive Autobahn. ;)

You forgot this is the biggest cry baby site on the internet.

you kids play nice in the sandbox.... now now...
