How much can a Toyota FJ Cruiser really Tow ?

Toyota is fairly conservative on their tow capacity numbers but that's not to say the vehicle can't tow more weight. From talking to a Toyota rep it's more on what it can safely stop that they're concerned with. It won't matter that you can get 7,000 lbs moving if you can't stop the weight and yes, you don't want the "tail wagging the dog" as other people have said here which is what happens when your trailer weighs more than the vehicle can handle.

Fj Cruiser Towing Capacity

This has nothing to do with engines this has to do with the transmission. You need a hitch and to find out what your gear ratios are in your transmissions. Some transmissions have taller gear sets (taller means lower ratios) to save on gas mileage. See transmissions use gears to help getting the car moving so it uses gear reduction or torque multiplication to drive the car. So if you are trying to start the car moving first gear may have a driving gear with 10 teeth and a driven gear with 40 teeth making it a 4:1 ratio. The engine supplies higher rpm which is then converted in a manual transmission by gear reduction, spoken about right before this, or in an automatic by internal torque converters through the process of atf fluid being pushed through them. Depending if your gear ratios are higher say 3.47:1 on the low end you will have a better towing chance than if it were 2.91:1. Also if your car has an automatic transmission do not tow in the 3rd, 2nd, or 1st gear slots those are for engine braking not towing.

Never go over the towing limit,your towing limit depends most on your axle ratio.With a short wheelbase you will get a lot of trailer sway even with sway contol,the longer the trailer the worst the sway will be.

it depends on the model.

Who cares!!!!
