Ok so please somebody post a picture with that model and engine cover off.


Um....... where are you getting the ECU calibration information from? Or is this your own theory? I hope that is case. Maybe you should stop because you are not the least accurate and you obviously did not consider the EPA requirements > The other factor is look at some of the engine ECU monitoring part specification for the Turbo as well normally aspirated engine for 2025. (if you can find them ) To reach higher power levels some of the basic fundamental monitors need to be changed and still that would only support if power producing parts like the camshafts (which they weren't) and the heads (they weren't) upgraded. And then we are back to square one the EMISSION STANDARDS.

Maybe you would be better to stop suggesting the ECU calibration supporting your power level theories.? Please it is embarrassing to the forum ! But entertaining to forums that specialize in Performance calibrating ECUs.

 

2025 CX5 NA- late model year build - Its faster , more powerful and handles better than all predecessors - the undisputed finest CX5 ever built - not unlike the Porsche 911- incrimentally improved over many years .... but never radically redesigned - buy one - then check in-proofs in the puddin
Its not bragging - its a serious improvment thar has taken the Cx5 to another level - My first instinct was Toyota gave up some amazing tech - as transmission transitions are seamless elegance - im considering another
Mazda clearly made a HUGE jump in technology and only the lucky few get the new tech B4 26 when it will be more $$ and backordered - mark my words- i had broken in 2 2.5 NAs recently and this sob not broken in - -has not bogged or downshifted in a strain for power ever - now im only at 200 miles - im just trying to tip off my fellow Mazda friends - jump on this bad boy - heck drive it first - if you have an earlier year - i havent even used " sport " mode yet - Look at this new cover and hose- intake routing -NOT the same as early 2025s ..so what happended ?? remember the occasional 69-1/2 GM 350 or mid year GTI engine changes - did the manufacturer throw up a big yellow flag ....saying LOOK we have a better engine than we just sold the last 6 months- uh not

 

ROLMAO so no picture of engine with the cover off

btw ever look at my signature

 

She only lifts her skirt for me ! sorry

 

Direct from Mazda's own website:
2026 Mazda CX-5comes standard with 2.5L I4 (187 hp) and an optional 2.5L turbocharged engine (256 hp).

There is zero difference in the 2.5L NA engine other than tweaks for better emission controls and fuel economy.
You cannot factually prove any measured HP difference without multiple professional Dyno runs on the different model years or "partial years" as claimed.
"Seat of your pants feeling" is based entirely on one's imagination or lack-thereof.
My prank playing son stuck a supercharged emblem under my CX-5 logo...I swear I automatically got a 50hp boost

 

you already posted a picture so lets look at it ?

No change in the intake for a long standing common for Skyactiv N/A = Normally Aspirated. By the looks of the intake upper no change in its design. The lower is only for sump PCV.
The coolant reservoir very common location as is most all the external mounted mount engine and parasitic drag components and even the HVAC system hoses are the same Wait it does like to you mentioned have that large and "FUGLY" engine cover? rolmao.
Basically there is strong indication on that picture alone no changes in the head and or cams. So it is very unlikely the base line ECU programing was altered because of Emission qualification and required minimum MPG which we could see on the required window sticker as proof.
So unless you feel "froggy" and want to jump to the request to post a picture of the engine cover removed your power theory is all wrong or as usual you fall into the category of "assuming the power advertised by Mazda is actual.


Honestly it boils down to if you are happy with your new Mazda that's all that matters.
Just don't try to BS on this forum when some of us know better unless you have the empirical information and not hear say or speculative unsupported information. In other words "GUESING".

 

The funny part of the posts to me is the absolute conviction the '25 has somehow been radically changed. No stats to back anything up of course. Just seat of the pants feel. How would you even remember what your previous CX-5 felt like without having it still on hand? If you were to take a 23 and 25 in identical spec to a dyno and track and get some numbers, then we can talk.

 

Yup most average owned and even enthusiasts cannot feel a 10-15 HP power increase so if i were to interpret that from a person that is not experienced and actively comparing vehicles with known accurate power output I think the power they fee is more in their head because of the sound an engine makes. I have had so many tell me on forums that parts installed like CAI, CAT-back exhaust, grounding the TB, and a few other common DIY installed parts increased their power because they felt the difference. Even when I know for empirical facts based on what those parts are never did. And even on some when an accelerometer was used to measure before and after I have had some suggest that the reading was wrong because they "felt" the difference of the power after the part was installed? The other factor is the newness of a vehcle and all the feel and smells it has I am sure convinces your brain it must have more power. The last thing is that in this case the 2025 is being compared to a previously owned model in which the assumption is that the drivetrain specifically the engine is in "perfect" health ion all aspects. One would wonder when the spark plugs were changed last when making the comparison as one example between the 2024 and the brand new 2025? Seeing 10-15 HP drop is not uncommon with spark plugs have over 10k miles or more on them and most never notice the slowly declining power until they get the 30-40K major service that changing the spark plugs is one of the items on the schedule.

How many DIY and basic vehicle owners in the pre 90's have used the "Italin Tune-Up" and noticed that their engine ran and felt better, more power?

 

That engine cover needs to have those "fugly" oil hand/fingerprints cleaned off it.

 

Congrats on your new car!
I traded in my 2019 CX5 GS for a new 2025 CX5 GS a week ago. Other than the climate controls, the infotainment system and the new car smell, I didn't notice any difference. Yeah, it will ride like a new car until the novelty wears out...
