The issue with the other comment on here is that yes whilst it is a physics issue, it's an inescapable one in fact, it doesn't remove the fact that no matter what any EV does the sheer lack of "excess potential energy" and the rule of diminishing returns leaves EVs basically forever out of contention when it comes to towing, u comfy reality, but also the same reason we use diesel to tow and less gasoline.
The writer of this article makes it sound like this is just a Tesla issue. The problem in of itself is physics. It doesn't matter if your truck is gas, Diesel or electric. your range when towing a large heavy trailer will be severely compromised. The only upside to towing with gas or diesel is the speed in which you can fill the tank and get going. The price you pay for that is measured in dollars. Granted, EVs are not for everyone and if you do extensive towing, you really need to assess the dollars versus time to charge. I am not a big fan of hybrids but Stelantis I think might have the right idea with an EV truck with a built in generator. especially if the all electric range is upwards of about 150 miles before you need to use the generator. Most folks don't drive more than 40 miles per day so the use of the OB generator would most likely be minimal.
Tesla will keep working on the Cybertruck efficiency rate with the ultimate goal to hit 500 miles of range on a charge with the extender battery in its current footprint. It better, since its chief engineer said the range can be cut in half while towing.
