HP difference between 2.5 NA CX-5 and CX-30

[zx10guy]

This question may have already been asked. But it's sort of bugging me to get an answer. Anyone know why the 2.5NA in the CX-30 has 4 HP more than the 2.5NA in the CX-5?

You couldn't feel a difference of 4hp between the two motors if your life depended on it.

I know. I'm not looking to chase small HP increases nor am I looking to modify my car to get more horsepower. Being the engines are the same between the two chassis, I was just wondering why the difference. It's just an academic query. Is it due to intake plumbing/routing? I also noticed that the engines in the CX-5 with cylinder deactivation are showing 1ft lb less in torque than the non CD engines. Just interesting to see the variations.

I checked the 2026 models and saw that the CX-30 had 1 less HP (186 vs 187) than the CX-5.

That's so odd. Because the 2025 CX-30 is showing 191HP.

That's the most HP I've ever heard of out of a NA 2.5L Mazda. Was it a sport/performance model or something special edition?

It was across the entire platform no matter what trim level. I tried to pull it up on Mazda's official site but they already pulled down the 2025 model info.

Here's a dealer website I found doing a search for the 2025 CX-30 specs:

2025 Mazda CX-30 Specs, Price, Colors | Tim Dahle Mazda Murray

2025 Mazda CX-30 Specs, Price, Colors | Tim Dahle Mazda Murray

www.timdahlemazdamurray.com

And it shows 191HP for the S trim.

My guess would be different tuning maps for emission reasons. The CX 30 is lighter then the CX 5 so maybe they could tune it for more HP with same emission results?
The loss of 5 HP for the 2026 CX 30 could be because of the same reason: lowering emission ratings.
