I have a 2020 Mazda CX5. I plan on adding a Class 3 trailer hitch. I’m concerned about towing this trailer:

Is that too much weight for the CX5?

 

What's the legal limit in your state?

What's the max tow limit in your owners manual?

What's the law on trailer brakes in your state?

( in my market, with a braked trailer you can tow 1800kg with a CX-5)

 

What engine in your 2020?
The 2.5L N/A has 1500lb tow rating/turbo is 2000lb
Diesel is 3500lbs

 

Skyactiv G 2.5.

I'm looking at the trailer towing-load table in the owner's manual.

I'm not sure what value I need to focus on.
TTW, GCWR, GAWR, GVWR.
I'm thinking the trailer may be too much for the vehicle.....

 

Like Lobsth an said NA is 1500# Turbo 2000# that's the loaded trailer weight. If you don't know what the Trailer weighs, a Grain Elevator will have a Scale, or a CAT Scale at a Truck Stop.

 

There is more to just using the max GVW. The altitude, road condition, the balance of the load very seldom gets mentioned as well as the state of the braking system.
A Skyactiv 2.5 NA is more than capable to carry the load but it's the other more safety factor to consider.
The other thing is you need to use 91+ octane fuel only!!!!!! And this is very important because the ECU will adjust the operation of the engine to produce the maximum power. Using lower octane fuels the ECU adjust operation which will lower the total on hand torque and HP .
The Turbo model under 3500 rpm is not much different under extreme loads than the N/A . And the Turbo will actually start to decline in power faster than the N/A because of heat produced under boost , the ECU adjusts to protect the engine lowering the power. Even the hyped up power graphs will show that somewhat.

 

This is definitely important on the non-turbo motors. You gotta use premium (91+ octane) for those heavy loads and towing per the manual.

 

actually the turbo as well. They are ECU controlled boost limiters so without carefully considering all aspects of towing the ECU may just give you a surprise when you expect a little more help from the turbo and you are not using 91 minimum 93-95+ octane better fuels or octane booster to raise the available octane fuel level as high as possible when towing .

 

You don't say what type of trailer it is cargo/utility/boat/camper/livestock etc.
GVWR (1359KG / 3500lbs) is the maximum safe gross vehicle weight of your trailer plus what it is carrying
REAR (1591KG / 3500lbs) is gross axle weight your trailer can hold
It is a Top Brand according to the tag and if you know the model you can look up its weight online.
As Alex said if you don't know you'll need to get it weighed.
Once you have that weight you will need to add it to your cargo weight to get the total weight being towed.
Total weight up to 1500lbs the NA engine
Total weight over 1500lbs up to 3500lbs need the turbo/diesel engine and to be safe you may want trailer brakes as well.

 

Yes another geat point. I always run 93 on my turbo and forgot people may choose to run lower octanes.
