Torque is a measure of force. It is possible to apply force with no reaction/movement. 100% TQ at 0 RPM IS correct. Hydraulic motors can do the same thing.
If they weren't able to apply TQ at 0 RPM, they would never start moving.
Beat me to it :)
Our servo motors for the refueling machines we build are a good example of 100% torque at 0 RPM. You can hang a fuel assembly off the hoist, with no brakes applied, and it will still not move. The motor has not been given a command to move, so it will apply as much torque as it neccessary so that the hoist does not move. You can hook up a hand wheel and try to crank the hoist up/down, but nope. It will apply full torque if it needs to, to hold that thing right where it is. Full torque at 0 RPM.
I guess that's true. I didn't think about it like that!

That car is probably faster than most of the cars on this site...

I would love to get behind the wheel of that "slow" electric car.

No shit, it runs.

You can not have HP with out RPM but yes you can have OMG torque w/o rpm. There is an electric drag bike that was close to what its ICE counter part did in the 1/4 mile.
