The cyber truck can tow more than twice the payload. My Jeep can probably tow a couple jet skis further than my friend’s Ford F35O can tow his 26’ gooseneck RV. Who cares?

If all you are ever going to tow is a couple of jet skis, then your jeep would be the better vehicle (if evaluating solely on towing distance).

If you own a trailer like this one and are deciding if you need the Cybertruck to tow it, you have the data.

Knowing capabilities and data helps make better choices.

Which, given the 20% larger battery on the "truck", is quite a difference.

The "truck" weighs around 20% more ( CT @ 6,000 lbs vs X @ 5000 lbs), so the larger battery pack effect is nullified and cancels out.

It’s more likely about aerodynamics (unless you’re going uphill with no regen, or doing a lot of stop/start)

That's not how these calculations work at all. Weight (if it doesn't change the size or shape) really only has an effect on rolling resistance, which is a small portion of overall losses.

The extra weight should make a marginal difference in efficiency. Just expect more tire wear.

That seems to be a rather simplified view, as if stemming from the world of frictionless pulleys and rope that does not stretch.

These are self-propelled electric vehicles that have regenerative braking. Regen is miles ahead of just dumping momentum as heat [as conventional brakes must] but it can never be 100% efficient -- and it may not even be able to begin to try to capture 100% of that momentum in the first place, depending on the particular braking circumstance.

These characteristics weigh heavily on how such vehicles perform in the real world, especially when the terrain is not flat. (And in this test, the terrain was not flat.)

Is that a good thing to have a very heavy car ?

Yes, it decrease range, increase road wear, increase tire/brake pollution, decrease road safety

I can't think of a single negative thing

Doesn’t weight have a massive effect on power needed for acceleration ? To go from A to B You need to get up to speed but also acceleration for regulating your speed after taking a turn, crossing a traffic light, passing someone over…

Newton's laws of motion would like to have a talk with you about those statements. A heavier vehicle absolutely needs more energy than a lighter one when all other factors stay the same.

Bigger and heavier cars are more expensive, thus they are worth more and they must be better.
