You are totally ignoring or missing the point that the car only has to move itself and it's occupants whereas the semi in addition to itself and crew has to full a trailer that may or may not be loaded.

Man look at those torque issues the little motors are having while towing 1000-4000 pounds rolleyes.gif

I'm not saying EV motors can't do it, but the energy requirements of the batteries will be much, much higher than that of a small car, meaning less range. Let's not forget the huge amount of time it still takes an EV to recharge (even with fast charging). Now imagine how long it would take to recharge a battery pack 10x-20x larger?

Exactly. They've go the power, but how many times can you do that before your out of juice.

Also, another thing you all don't realize is how overbuild 18 wheelers are. The components are not stressed. If you took the 700hp motors from a model s, they would quikly burn out on a long grade. Keep that same overbuilt factor into your calculations.

You really need to read the articles before commenting.

"Musk is proposing..." rolleyes.gif Now we just blindly take pitchmen at their word is it? Okie...

OK, let's see. Musk has already developed a successful electric car and the company to manufacture and sell them. He is making progress on his space project. He has developed massive tunneling machines that are in use now. He started PayPal. He is no mere pitchman. But then again, you just like to argue against facts.

I worked for American Salt Co, typical loads were in excess of 10,000lbs.

You have any proof to discredit EV Semis?

A video above shows a Model X drag racing while towing a 4000 pound car.

The semis will of course have bigger components than a car. Thus enabling them to tow more.

Does all this need explanation?

Bro, 2 things: (1) I'm not saying it can't do the work, I'm saying the time that it can spend doing the work expressed in range will be negatively impacted. So please link a vid with a side by side of two model x's one towing something heavy and the other not. (2) It's an apples to oranges comparison.

I'll gladly step aside with a comparative example.

Sure you know how to use youtube right? rolleyes.gif

Right. You need to prove your claims, not me prove them for you. of course the range will be lower LOL

No one is denying that electric motors are superior to IC up to a certain weight.
