No they didn't.

"When it arrives in the US later this year, the Miata will be offered with a 2.0-liter Skyactiv-G inline-four, producing 155 hp and 148 lb-ft of torque." is what Autoblog said. Probably a different writer for the article than the earlier article. No mention of Mazda confirming it.

It's going to have more than 155hp.

actually I saw on Wiki that it will have 160!

Autoblog, Road and Track, Edmunds, Motortrend, Automobile Mag, Motor Authority...

I wasn't searching very hard, there are hundreds of other outlets, not sure what you're trying to prove.

"Mazda has officially confirmed that the U.S.-spec version of the 2016 Mazda MX-5 Miata will make 155 hp and 148 lb-ft of torque from its standard 2.0-liter Skyactiv four-cylinder engine. This news comes from the Miata’s global launch program where we drove a right-hand-drive model powered by the 1.5-liter engine that's standard in other markets."

I think the 155 hp story developed because some publication saw the webpage for the Chicago auto show listing the horsepower for the 2015 Miata as 155 hp. All the publications ran with that story claiming that "Mazda has officially confirmed" it, but I've never seen an actual Mazda source confirm it.

Mazda (as far as I know) has neither confirmed nor denied 155 hp despite what the major publications are claiming. And the Chicago auto show has since pulled that figure.

I think it was just bad journalism, but who knows, maybe 155 hp is right.

Bhp is Bhp. Apples to apples. Mazda to FR-S. I have already posted the PTW ratios based on the specifications provided so far. Math doesn't lie.

The Mazda weighs about 20% less than the FR-S. The FR-S has about 30% more brake horsepower than the Mazda. Do the math.

Until someone produces a credible source saying that the 2016 MX-5 has more than 155 ponies, I stand by my original statement.

Edmunds.com said exactly the same thing, word for word. Where do you suppose they got it? Maybe a Mazda industry press release? Or is Edmunds getting their information from Autoblog?

My point was that the miata has never been about horsepower, just like the 86. Sure the 86 has a better PTW, but just barely. I would give up some of that 200hp if it meant making my car lighter.

Nor do lap times.

Power makes a car faster down the straight bits.
Lightness makes a car faster everywhere.

I've got mountains of race footage that makes this point.

The FR-S is at 13.8 lbs per horsepower,whereas the 2016 MX-5 will have 14.2 lbs per hp. These calcs are based on curb weights of 2205 for the Mazda and 2753 for the FR-S, with 155 and 200 bhp, respectively.

You can't go by peak power alone.

I did the math.

Going by the rumored specifications, the 155 HP ND should be a tad faster than the 167 HP NC2, which is about as fast as the FT86 (though many think the NC2 is underrated).

Math does not indeed lie.

To figure out which one is actually faster around the track you have to do the integral of speed function around the track.

So peak horsepower is actually less important than torque / acceleration unless you are racing on an oval.

My original post stated as much. More torque is certainly equal to more acceleration. I also stated that the gear ratios would matter. I was merely addressing the question of power to weight ratio, based on the available specifications of both cars.

The PTW ratio of the Miata using my assumptions (2205 lbs curb weight, 155 bhp) is of course slightly optimistic, since the actual curb weight of the non-Japan version will be higher due to the larger engine. Therefore the actual PTW ratio will be a bit lower.

Do you mean that the FR-S is about as fast as the 2016 or the 2015 Mazda? I test drove both the 2015 FR-S and the Miata MX-5 almost back to back last September, on the same day. There was no doubt in my mind that the FR-S had better acceleration and more power than the 2015 Mazda. It also handled better.

Clarification, please!
