Hi All,
I have a 2019 CX9 (2.5L turbo, AWD) and I’m planning to tow a 4.150 lbs. boat with a two-axle trailer with surge brakes, not for a very long distance, for about 150 miles mostly flat and a couple of miles with moderate steep.
I’m aware that manufacturer states 3.500 lbs as towing capacity (please dont answer that I should check and follow manufacturer data etc etc 😅&#128591 but I wanted to know your own experience towing something similar and how the car managed.. any issues and/or dashboard warning?, all good? How the car brakes works, even with a braked equiped trailer.
it is known that towing capability stated by the manufacturer has a security margin and considers, among others, longer periods of towing with steep roads, frecuent towing, etc.
thank you!!
cheers

 

I can’t answer professionally as there is no empire facts or data to support what you are contemplating. However I can give you only my thoughts based on practical experience, so this is what I am thinking on.y for myself. If you choose to think the same then it is only two people with simulator thoughts nothing more and others reading should be aware that neither you or I are stating these thoughts as anything but A random thought .

that said my thoughts based on lots of out of the technical and engineering manuals.

A driver that is aware of exceeding the load limits but has good driving and towing experience should be able to fudge a bit.
Brakes or rather the braking capacity will be down maybe close to 35% . So O-60 mph stopping distance will be increased by several more seconds and needing more driver steering control in an emergency stop incident.

the transmission is like to exceed the engine temperature witch will slowly and at a lI ear rate reach likely 210f engine and 223-230f transmission on flat to semi flat roads. If this is the case I know At the end of the trip a pan fluid change is prudent . It hills or mountain travel then I know to keep a close eye on the coolant temperature because it could reach the limit of the safe engine operation cooling system @214f.

The only thing you can’t find anywhere on the internet is the torsional strength of the automatic Skyactiv transmission. Here is where only a few of us know it does not like high torque levels . It will break the case. But this would be more to think about engine molders and wanting to exceed 400whp . But as far as I am aware now one has attempted that and published it? Mostly because there are very very very few individuals whom know how to adjust transmission control in the ECU “correctly “!


Lastly knowing that the stated load limits are in fact based on full engineering safety margins ,so they are accurate and not really meant to exceed, I would not publish or talk about what my towing plans are. I could lose the complete drivetrain warranty and possible chassis warranty coverage as well.

Now of anyone asked me on the clock I would tell them Never exceed the manufacturer towing limits!

 

What does the insurance company say if an accident happens during your trip?

 

In the hypothetical you don't talk to the insurance company...!
Based on the ops post I think he is intelligent? Or I would not have posted what I did ion the first place.

I think you also know very well what the response would be anyway?

 

Based on the seriousness of a possible accident, the police can do an investigation regardless of whether or not you tell anything to the insurance company yourself.
I would not dare to take the risk ...

 

Again I read between the lines the OP is an intelligent individual and will make his own choice and I believe is well aware of consequences.

And yes, we all understand that you would not take the risk!

Honestly if you read my response, you would read and maybe interpret my concern is more about the transmission then the capabilities of the MAZDA being able to tow something beyond its stated capacity. And while the OP has not responded back again I am sure that is what he may be thinking about now as well based on the information in his first post where he may be towing.

To add I seldom almost NEVER suggest or post anything that has no Empirical data or facts but as I keep repeating, I did introduce my first response with a disclaimer now didn't I!!!!

So we all have read you response and thoughts on the topic do you and I need to really continue?
Hers is a question can you answer truthfully without running to the internet? What is your stated braking distance performance on your Mazda and how it was achieved?

I am not trying to put you on the spot but my guess 1 out of 100,000+ owners know that answer?

 

English is not my native language.
What does "YOPU" mean?

 

Its a type- o I didn't catch.
Grammar, spelling sentence structure, etc., was never my strong subject in school and even in college I met only the basic requirements.

 

YOPU slang

 

Let’s focus on the technical and empiric experience please. We can leave all the other factors (ensurance, other models, moral, religious, politics 😂&#128514 aside. It will work, trust me 😄. Im joking.. a little. I do appreciate your comments.
Also I do have experience towing. With the CX9 will be first time towing this boat.
Anyone have experience on this matter with CX9 model? Thank you all!!
