Torque does not increase, only HP above 4k RPM.
According to Mazda, for the 2020 model, torque increases from 310 to 320 ft/lbs with the use of 93 octane fuel.
Torque and horsepower cannot be separated from each other. If the torque has increased, so has the horsepower. What I find MORE likely, however, is that the torque has not increased relative to the 2019 model, but rather, they have simply done more disclosure of data, and it was always this way.According to Mazda, for the 2020 model, torque increases from 310 to 320 ft/lbs with the use of 93 octane fuel.
87 t o 93 isn't noticeable by seat of the pants, but if you go and race someone and are dead even with 87, you will edge them out with 93.Considering how much extra kick I can feel already with 87, not sure if I’d notice the difference on 93. Our 2018 felt pretty anemic on some long onramps. This thing, not so much!

While you are factually correct, I find it doubtful they would only have a shift and peak to 2500 and not before...and not after. I've never seen a tune give midrange torque with zero peak hp bump.True that they are relational (HP= T x RPM / 5252). A bump of 310-320 ft/lbs peak torque @ 2000ish rpm would also have a corresponding bump in HP to match at the affected RPM's but if torque drops off below 310 before peak HP rpm it would be possible to have an increase of peak torque without an increase in peak HP.
If that additional 10 ft/lbs carried through the rev's up into the rpm range of peak HP I would agree with you but it is possible to have an increase in peak torque WITHOUT an increase in peak HP.
I don't know if the extra torque carries through to higher rpm's or not. I'm just opining that it is possible to be as Mazda said.
