this is this odd freaky trans difference that has been touched on before.. the gearing is different.. i am thinking this is a jdm car..
btw,,, it is most goodest.. tards!!!

But I'm still not sure what the reason is for the higher ratio, fuel economy?

^ no, because we do not know yet whether Genes have anything to do with Sarcasm, first we must know whether sarcasm is nature, or nurture, if it is nature, we must find out what chromosome it is on, they we must name it, something like Sc12B, then we must find different alleles for the gene, only then can we possibly create a gene therapy, and that must begin early in life because that is the most receptive time of a human cell

I noticed this with other tests, the best example is the Motor Trend test w/the 350 & s2000. It showed acceleration in 10MPH increments so you can see exactly where the 8 trails off. Up until 60 the 8 is .2 seconds behind the s2000, and from there it looses another .2 seconds 60-70, another .2 sec. 70-80, another .4 sec. 80-90, than a whopping 1.2 sec. longer 90-100. The redline shift into 4th is 89mph, so did Mazda pick a lousy 4th gear ratio? Fuel economy reasons?
Now all cars loose pace as they accelerate, but the pace of the loss is usually gradual. Not so with the 8. I noticed it soon after I bought the car, that the shirt into 4th is like driving into wet cement, though the acceleration seems to pick up again once you clear 100mph. Doing roll-ons with a friend also confirmed this, but I noticed that delaying that shift into 4th until fuel cutoff (9300 or 9500rpm – depending on who you believe) brings you up another 3-4 mph and that drop off in power isn’t so severe once you shift.
Anyone else notice that the shift into 4th blows? Maybe next for the 8...a 7 speed direct shift transmission

He's as bad as Can
9291150, Kind of understand what your getting at. But its hard to figure this out on the street. I noticed it when doing the
long course at Pocono .
The thread in the link has a map and two videos of my 2006 trip. I am leaving turn one around 100 and when shifing into 5th by the exit By the time I have to brake for the tunnel turn I might get up to 125.(what I need to do it work on taking turn 1 faster which I hope to do this July). But I do notice a lack of "umph" when shifing out of 4th even on a a roomy track.

I have a JDM spec car with the higher 3rd gear ratio . It seems to me that the ratios are well spaced & I don't notice 4th being sluggish because I'm already doing over 100mph when I hit it.
I think your US ratios would be better for short courses where you stay in 3rd most of the time .
