The 2.5 engine shuts down 2 cylinders during cruising...

I love all my previous Mazdas..

But this "FEATURE" will stop me from buying this car. I've bought 5 brand new Mazdas since 2012, and loved this brand for it's excellent engine drivability.

2012 CX5
2013 Mazda 6S
2) 2017 CX3 GT
2019 CX5 GT Reserve

I don't care how they sugar coat it. I'm not buying it. Unless I can disable it without going to the aftermarket ?

Customers should have the option to disable this garbage.

My understanding is that cylinder deactivation is only a "feature" on the top level "Premium Package" trim in the US: https://www.mazdausa.com/siteassets...0/cx-30/2020-cx-30-compare-specifications.pdf

I was unaware of Mazda's cylinder deactivation issues/recall when I decided on the mid level "Select Package" for my CX-30 but that definitely would have been a consideration had I known. Also the fuel economy ratings aren't any higher with cd.

If this is actually the case, it doesn't make sense to me that they would have a separate ECU programming for the same engine.

Also, for my own interest, I am only interested in the top of the line premium package anyway... I like all the bells and whistles.

They can keep this one for now... NOT interested... not even for a test ride.

don't understand why you call it "garbage" some other manufacturers have been using it for years (Honda for example) on some of their engines.

This feature is also standard on the top GT model in Canada but there is increased fuel economy with this feature.
2.5L without - 9.9 / 7.7 (AWD)
2.5L without - 9.3 / 7.1 (FWD)
2.5L with - 9.5 / 7.4 (AWD)

There have been a raft of complaints regarding the intrusiveness of the cylinder deactivation on the Mazda 3 forums. I wouldn't get it either if I were buying a Mazda today.

I think it's been on all CX-5's and Mazda 6's for a couple years now

 

[Maznut]

It defies logic, adding a layer of complexity for no significant gain, that can only come at a cost in reliability and longevity. Its got me hesitating too. Just as dumb as the start/stop systems some manufactures are using. Luckily, my early production 2017 CX 5 does not have it. I usually only keep my cars 3 years/40k miles or so. I might chance it.

 

[R-Brown]

I didn't realize that they were doing this with the CX-30 but in all honesty it's not a deal breaker for me, especially if it's only standard in the top model.

Does anyone know if CDA comes with the FWD Premium trim in the US or just AWD Premium trim? Honestly, from what I've read, I don't want CDA and I can live without AWD but I'd really like to have the Premium trim.

according to the Mazda US website, it's a feature of the Premium trim regardless of the drive-train.

 

[Scott Francis]

Yeah, I've see that -- just trying to twist it into the reality that I would prefer (no CDA). The funny thing is that the gas mileage for FWD with and without CDA is reported to be the same (rounded to integer numbers) so why would they even bother with it if there were no significant improvement? Arghhhh ...

Sorry, not following. Your post #4 doesn't list mileage for FWD with CDA. Are you suggesting that Premium FWD does or doesn't come with CDA?

 

[Maznut]

Think his point is it has been used reliably by other manufactures and even Mazda for years. But I wonder if he is aware of the problems the new 3 had with it even though it was supposed to be proven technology. Some leading to total engine failure, later blamed on software by Mazda.
Am I right conwelpic?

remember this is Canadian info the GT model (similar to the US Premium model) is not available in FWD in the Canadian market.

don't know, it was just a general comment that came to mind when I read the post.

Here in Blighty we don’t have a choice. Irrespective of trim level if you order a Skyactiv G 2.0 (we don’t get the 2.5) it has CD but includes mild hybrid as standard. Our Skyactiv X 2.0 doesn’t have CD but includes mild hybrid.

I 100% agree with you...and this is on 6's and 3's also except not on turbo. The lower trims CX-30 does not have it but then you get no sunroof. This might save you 10-15 mile extra per tank but what a totally risky tradeoff especially down the road when out of warranty. There have already been cases of rocker arms coming off on CX-5 and Mazda 6!!!

It is only on top trim level not select or preferred.

We get it on every trim in the U.K. although we only get the 2.0 G and 2.0 X engines. The deactivation is completely unobtrusive and you can only tell by looking at the graphic that shows no cylinders running (hybrid keeping the car rolling), 2 or 4 cylinders running. Certainly in the U.K. (and probably Europe, too) it’s about lowering the emissions rather than just, potentially, improving MPG. All new cars from January 2020 have an emissions target of 95 grams per kilometre of CO2. This was once just Prius territory but is now the target for all new cars. For every g/km over 95 the manufacturer is heavily ‘fined’. This fine can add up to a £1000 for every gram over 95 being added to the list price for the customers.

It’s the same reason many cars sold in European now have a mild hybrid system - think Peugeot, Kia, Ford, Honda and now Mazda.

Of course, all of the above might be irrelevant to the USA?
