mazdaEdit already works with the skyactiv 2.0 so I think retuning the ECU is not going to be such a struggle once a few motivated people document it. There is a British tuner claiming to have a 2.0 in a new mazda3 tuned to 200 crank with fuel and cams.

Unimpressed.
My 01 got 27/33 consistently on crappy 91oct and not even hypermiling it.

Great news for you!

You exceeded the factory rating by 17.39%.

Your new revised numbers, just for you, for the ND are: 32mpg city, 40mpg highway.

Sound better?

It's with the 2.0, those are US EPA numbers. 36 MPG highway for the auto.

This. Your '01 was rated at 28 highway.

We really shouldn't be surprised that this doesn't get the same mileage as the 3: The gearing on the 3 is super high, and it's a more efficient FWD layout. The new Miata is going to get fantastic mileage when driven reasonably, and I am sure we will see reports of 40+ at 65 mph highway.

I guess I expected more out of an engine designed recently and not in the 80's, a heavily updated drivetrain, and a car that weighs less. If it's not gonna make decent power, it should at least get serious mpg. I mean we're talking about 15 years worth of technology. Way more if you consider that the NB is just a hopped up na, not a complete re-design. The 3 also weighs much more and I bet it doesn't have better aero either ( just a guess )

You can likely have better MPG out of it.

If you want to gear it like a cruiser.

Show me a legit sports car that gets super awesome make-me-jizz-myself gas mileage. They don't exist.

Every car is a compromise. The Miata is no different.

I get over 40mpg out of my F2 powered car, but yet... i don't get salty when pretty much nothing but diesels or hybrids does the same in the year 2015. Be realistic, friend.

The Miata's a convertible. The aero on the 3 is going to a ton better.

Also this.

I'm reasonably sure my NB's drag coefficient is closer to that of my Cherokee than that of my MX6.

I keep looking at that image and thinking "Boy, there's not a lot of room next to that exhaust manifold... And is that an ECU sitting beside it?"

city mileage with reasonable driving will be better, or at least as good as, the 3 because lighter weight (not reflected in EPA ratings, but will come out in the real world. Might not actually be BETTER just because RWD). Higher speeds the Miata will be hampered because drag.

I too was hoping for better, but am not surprised. Look at it this way: 6 MPG more than the current Miata on the highway.
















OK you're right -- that's disappointing.

Hilariously close to that of a Grand Cherokee.

cd is not the same as total drag.

Drag is cd * equivalent flat-plate area.

So it'd have the same aerodynamic drag as a Jeep, if it were the same size as a Jeep.

For reference, as brick has a cd of ~1, regardless of the size of the brick. Large bricks obviously have more total aerodynamic drag than small bricks.

C5 and C6 vettes will get 30 on the highway if you either drive like a bitch or put a tune on them.

I learned ( or rather, you helped me realize ) something new today.

Thank you.

Less sob-stories about how you won't be able to afford buttsex lube because the ND doesn't get better mileage than your pink moped, more discussion on where the turbo will go
