That's one sure way to tell. Hope Mazda's implementation is better than Mercedes. Saw one the other day stop and start and it cranked on the restart for about 2 seconds and it was loud.
Does my 2025 CX-5 Have Cylinder Deactivation?

On my CX-50 it's very quick to restart, but I don't like the thought of the increased wear & tear on the engine, so I bought an aftermarket module to disable it (basically it "presses" the button every time you start the car).
Having said that, I can't believe Mercedes' version is any worse... I wonder if that car you heard had other starting problems.

I trust Mazda's engineering on i-Stop. The procedure is completely different than a normal engine shut down and restart.
That said, the biggest benefit of stop/start is if you frequently do a lot of idling. This reduces fuel consumption and gas and particulate emissions. If you do a lot of quick touch & go, I can see the desire to disable it.

Side note here...You can list your Mazdas via "Custom title" (under Account details) instead of using the vehicle field...Should appear a bit cleaner too...Hope that helps

I have iStop on my new CX5 Akera and it was on my previous KE Akera and the KE GT before that. Thats around 12 years of owning an iStop CX5.
Every CX5 in Australia has it fitted.
Never had a problem once with it restarting almost instantly. Not once in all those years. And 11 of those years it was the diesel version that doesnt have the compression assisted restart that my new 2024 Akera 2.5 does- the diesel relies fully on the starter motor.
Starts so fast that by the time your foot gets from the brake pedal to the accelerator its started and ready to go.
It messes with some people’s heads, but rarely creates any issues in reality.
You just have to get used to it. Much the same as Im having to get used to watching the HUD and overcoming decades of glancing down at the instrument cluster - it takes a while to get used to it, is all.
“if you do a lot of touch and go” then all you do is use lighter pressure on the brake pedal and it doesn’t activate. You can soon learn…

I owned a 2018 Grand Touring CX-5 (bought new) until about ten days ago.
I have a low tolerance for risk, and what I'd read about cylinder head cracks, defective valve lifters, and occasional transmission problems in 2018s spooked me enough that I decided to replace my 2018 with a new non-cylinder deactivation CX-5.
Specifications for the S Preferred trim indicate that it doesn't have CD, and although it lacks a few of the cosmetic upgrades of the Grand Touring, for the most part all the features I care about are included, so that's what I bought.
Beginning two or three weeks ago, while checking the Mazda inventory I started seeing 2025 S Preferred CX-5s with a VIN where the eighth digit is M. (L = without CD; M = with CD) So, that motivated me to pull the trigger and buy a CX-5 without CD while they're still available.
So, it looks like Mazda is phasing out the non-CD engine, even in the trims where CD is not in the specification. If anyone else is mulling the purchase of a new CX-5 without CD, the window you have to do so is apparently closing.

I don’t believe the select trim has it.

Why wouldn't it? Every trim except the Turbo has the same engine.

Depending on the year, the absolute lowest trim(s) did not have CD. My previous '20 CX-5 GX was the Canadian base model and it did not have CD. My current '22 CX-5 GS is one higher than the base and it has CD.

The window sticker will indicate if there is CD.
A simple way to find out if your CX-5 has cylinder deactivation is to look at the eighth character of the VIN. If it's M, it has CD; if it's L, it doesn't have CD.
For the 2025 model year, some S Preferred trim CX-5s have CD and some don't. At the time I was shopping (I bought mine at the end of May. Its build date is 4/25.) Mazda's "Compare Trims & Specs" web page indicated the S Preferred trim did not have CD. The local inventory reflected that. The eighth's character of the VIN of all the S Preferred CX-5s was L. Around the last week of May, I started seeing VINs of cars "in transit" to the local dealers with an M as the eighth character.
Until today, I hadn't looked at the "Compare Trims & Specs" web page for a while, but I see it now says the S Preferred trim has cylinder deactivation.
Others have said that parts shortages were why Mazda built some CX-5s without cylinder deactivation. That's probably right.

What a bizarre distinction. Sometimes Mazda's decisions don't make sense to me.
