Will the range actually meet 250mi in real world driving? Remains to be seen.Cybertruck RWD is now listed as eligible for the $7,500 tax credit. It is expected to be released in 2025. If factoring in the tax credit it will start at $53,490
I'm sure there are use cases for a very local operation, but the consensus seems to be that it's not unusual for contractors to operate within a 100mi radius of the base. Bare RWD truck may be able to do that with little issue, but not while towing equipment which is the second significant use case.
Tesla does their EPA calculations very tightly. Real world driving? Yes. 80mph freeway? No.
...and the RWD does exactly that.
It's a similar matter to the current models. How well do they perform regarding the range estimates ? Not much reason for RWD to be much different, other than perhaps being a bit more efficient due to the lower weight.
What's odd is that a single motor ought to be able to be configured to get better range. Are they shorting on battery cells or, motor type? Would that portend a possible Long-Range version down the line?
Tesla provides the data that FuelEconomy.gov posts...
Smaller pack
I don't know how you figured that out, seems baseless. My average efficiency for driving empty on average is about 360Wh/mi - that's about 90% at 55MPH. Same routes with an empty(!!!) equipment trailer go to 580Wh/mi, and with a light load over 600Wh/mi. I haven't tried towing at max load yet, but I'm pretty certain it will be a sad experience.
Single motor version will likely have an induction motor, which is less efficient at speed than the reluctance motor. Right now when dual or triple motor versions cruise at speed induction motor is de-energized and only reluctance motor(s) is engaged, getting a slight improvement in efficiency. On the other hand additional motors add weight, which reduces efficiency, so that probably gets cancelled out. Then there is the battery pack - again going with a smaller pack you reduce vehicle weight thus improving efficiency, but you get some range reduction as the capacity is less...
Your example, 123/0.390 gets you about exactly the range on the tin. Double the consumption for towing, and you get half the range on the tin.
My point is it's not a double. Double is what you get with a moderate load, whether it's due to the weight or aerodynamic drag. When you're at max load you will have 1/3 the range. In fact because RWD is inherently more efficient while empty, the range reduction will be significantly more pronounced when towing at the max rating.
That's not how weight affects towing. It's nearly all from aerodynamic drag.
Weight impact is around 2Wh/mile per 100 pounds.
