How far, and how quickly? How many stops along the way? How easily will it be to get to a charger with a 14,000 lb. trailer attached?
Inquiring minds want to know.
From a previous post in another thread:
Here is a quote from someone at the Tesla forum on the concerns on the reduced range of Cybertruck when towing. I have no idea what this techie is saying but it's good enough for me on the range issue.
"I don't think the cybertruck will be affected as much as the Model x. The model x uses induction motors. An electric motor is most efficient when it is under a full load, so for model x efficiency reasons Tesla would not have put a much bigger motor than is needed for non-towing use. This means that when model x is towing it's motor is not at full back emf and is slightly leaking. ( Not all the energy goes to power, it is wasted as heat).
The cybertruck will not have this problem because it will use switched reluctance motors. With switching you can alter the timing to increase torque at the expense of top speed. Cybertruck will have a tow mode. I believe this mode means top speed will be dropped from 130 to say 85. power= torque x rpm so if you lower the rpm you get more torque. I have seen electric motors where you can set the timing for as much as a 20% difference in torque."
