the later years were not less powerful, i think they simply corrected the figure.

just put a NOS sticker on your windshield
that for sure will give u an extra 30 HP

It was EPA rating for fuel efficiency, not for power.
Mazda has a history of misstating their cars actual output, then correcting. So significantly in fact that several years ago, Mazda offered an incentive to those who purchased Miata's with the misstated power output.

Although the 2010 mazda 3 only got a modest increase in HP I think it got something like a 20ft/lb increase in TQ :shock: Also acceleration and how the power is put down cannot be deciphered from the peak numbers, we need to see the gearing and the power curves in a graph.

Yeah, IIRC the same thing happened when the RX8 came out. Mazda even gave people the option of returning their car if they were that unsatisfied.

Daniel, I hate to correct you a little. You are correct on the revised EPA standards. Yes, Mazda did mistate the power rating on the Miata (I believe just the Mazdaspeed version though).
There was a revision in SAE ratings of power as well...around 2005, SAE International's J1349 Certified Power Standard. This affected other vehicles, not just the Mazdas. Several Japanese brands were rated lower than previously stated...while not actually losing power. Several domestic motors, especially large-displacements, had a higher rating! Great article, albeit biased coming from Detriot News: http://www.detnews.com/2005/autosinsider/0508/17/A01-283759.htm
2/10s of a liter aren't going to yield a much higher PEAK horsepower rating, but a more useable powerband. People need to get over just looking at PEAK horsepower ratings, they only tell a fraction of what the car is capable of.

Okay, I misread what you had stated, I guess I should have aimed my correction elsewhere...sorry.
Yes, the EPA did not change HP rating standards, the SAE did. And is the reason why the 3's motor is rated 4hp lower.
I was under the impression that the Mazdaspeed Miata had a rating issue as well.

No worries, my post was poorly worded.

Very possible. I just happend to recall the issue with the 01.

Hey Reza, I see you live in California. Like NJ, that means your car must meet a stricter EPA standard than the federal standard. As an ULEV, our cars have a little more pollution equipment on them. Consequently, your 2.3-liter produces only 151 hp, not 156 hp. (This is different than the “SAE certified” horsepower figures that began in 2007.)
That might sound terrible but as others wrote, torque accelerates the car and not horsepower. Your CA engine produces 149 lb-ft of torque compared with 150 lb-ft of torque for the federal engine. Therefore, there is no noticeable difference in acceleration.

Okay, that explains why so many Japanese cars "lost" HP sometime around then. I noticed several RSX, Camry, Matrix, Corolla models all "lost" HP. Thanks for the info.

yea they just refigured it.. the older models dont have more power...its the same engine lol. But I agree about the 2.5L. 170hp would have sounded so much better lol. you add the intake and exhuast to ours and were probably about the same lol.
plus that new 3 is gross. I like the smart keyless enrty tho
