Most EVs have poor tow ratings because they have poor tow ratings. Literally.

In the EU, where speeds are lower, their ratings tend to be higher for the same vehicles - and this affects ICE vehicles, too.

So it's about brakes, body stiffness, and bothering to test at all more than it is about it being electric. These things cost money, and if they don't do it, they don't have to spend the money.

Sorry wrong again.

The electric motor efficiency has nothing to do with available torque or the motor's torques curve.
At low RPM, with lots of traction and without the right gear ratio for a high load slow speed, an electric motor will still struggle to tow and will stall. Not all EV's have multi hundred kW/hp outputs like Teslas.

This is what Setok is talking about, and he is correct.

Sorry, but tow rating has little to do with available torque.

It has to do with whether the manufacturer has bothered to test and guarantee a tow rating.

The rest of your post is nonsensical.

There is a requirement to demonstrate that certain trailer mass needs to be accelerated up a hill grade in order to receive a tow rating.

Torque is what causes an object to accelerate.

Time to switch your brain on? Morning pre-coffee fog?

None of the things in US towing ratings have to do with speed up an incline.

🤷‍♀️.

Towing capacity has lota of different things that limit it, but tow rating is specifically a manufacturer supplied number. That they may or may not supply.

If you want to argue, you probably should stop with the insults.
