It will have a 1,000 HP electric motor. It will suck off road.



I was arguing with a guy about that. He was of the opinion a soft start to the motors would make it perform good off road. I just don’t see that helping all that weight and tq enough to make it worth a shit.

Even though its a 1,000 hp motor with enough torque to do amazing things, its just like a diesel. The more throttle (amperage) the more torque it will make. Limit the throttle and it will just apply small amounts of power. Those motors are not all or nothing like a flip switch.

Look at the Tesla, in normal eco mode I have heard its pretty unimpressive, but sport mode is a different story.

I watched a video of a Tesla 3 4X4 off road. It sucked. All it did was dig 4 holes . Too much instant TQ.

They will have adjustable ends points for throttle, I use them on my brushless lipo rc trucks. Otherwise they wouldn't do very well off-road, I will say when amperage is low they get a tad jerky though. The hard part will be keeping them operating smoothly under low throttle input.

It kinda depends on how many poles the motor has and the programming for throttle and current delivery. This is assuming it is an AC motor as it should be

Motors with more poles will have lower RPMs and higher torque. The lower RPM can be compensated with more gears or more commonly higher drive frequency with a hit on efficiency

Low pole count, like four or less, has a hard time running low speeds without stalling. Increasing the current helps but is hard on the motor.

If the engineering team and programmers are smart and communicate they can make it work well in all conditions and have the 1000 HP

Actually, it is a driver issue. The darn electric motors don't give any feedback on how much torque they are putting down. No Motor noise. So you don't really know you are spinning tire. I know this from driving my EV in poor traction situations.

Now, after a little practice, I have learned to keep an eye on the speedometer and adjust my foot to the conditions.
