A Tesla Roaster can make over 7,000 ft lbs of torque so the numbers may be correct.
Electric motors make very high torque at very low RPMs.
Since HP = Torque * RPM
If we back calculate, the hummer will be running 457rpm at max HP (assuming peak torque and HP are at the same RPM which is typical for electric motors)
The real issue is feeding that motor. 1000hp equals 746 kw. Assuming they put 200kwh battery pack in (more than double the tesla battery pack)...that gives you about a 16min driving range.
That assumes you can discharge the batteries that fast without damage and all the cabling can handle the massive amperage.azrving wrote:
Didn’t think whole electric thing start because of global warming and resource depletion? How is this type of thing saving the planet? Not that I'm a global warming nut but wth. How would anyone associated with an RV be concerned about all this electric stuff anyway? Surely it’s not out of a concern of resource depletion or GW. If anyone is worried about that skip the RV stuff and stay home. That would be much greener, right?
Main advantage of EV is lower cost of driving,no exhaust fumes and way less maintanance on such vehicle.
And with truck like Tesla being made from rust resistant stainless steel it should last a lifetime.
I doubt global warming is such big problem anyway,few degrees more wont kill the planet.- Didn’t think whole electric thing start because of global warming and resource depletion?

- Wonder what kind of mileage range they can squeeze out of that much power.
- 11,500 might be at the wheels after a 10:1 or 15:1 gear ratio.

Electric motors make very high torque at very low RPMs. - Labeled as a 1/2 ton means it is just fast.
- That’s enough HP and torque for most of us.
