No. Electric motors are potential torque beasts. That is why they, ALL of them in cars, are mated to motor controllers. The controller may be integrated into the motor assembly so as to give the impression that the motor is tame, but the reality is that every electric motor has the potential for damaging/dangerous levels of torque. https://en.wikipedia.org/wiki/Motor_controller "A motor controller is a device or grou…

Well wouldn't the controller also be used to distribute the inverted power to the poles of the stator in sync with the rotation of the hub? I am pretty sure the controller could be there whether or not it was specifically modulating the torque to be lower.

What? Electric cars have far better low-speed torque than ICEs. How do you think Teslas can do 0-60 so fast?

I don't think you understand the GP comment.

All electric cars are torque-limited certainly != electric cars do not have good low-speed torque.

It is precisely because electric motors are capable of such high torque that they have to be torque limited.

Wow, what nonsense. This is a very low volume car at best. This is not Tesla competition, VW is. There are already tons of EV companies and all the big automakers are already producing EV as well. Just in terms of pure electric vehicle you have Rivian, Lucid in the US, there is Xpeng, NIU and others in China, and those are already valued in the billions. Tesla skeptics have been saying 'competition is coming' for lit…

I was not speaking specifically of DeLorean but the fact that more and more major manufacturers have begun testing the waters (none of the makers you listed I consider are major in anyway they will be crushed first along with Tesla). We are witnessing the calm before the storm which lot of Tesla fans seem to be be displaying myopia for. You simply don't know what these automotive giants are planning (possibly colludi…

I bet you I have spend much more time then you analyzing. And I know about all the different targets from all the different car makers. They actually have public plans of how many EV they will build (and very often they actually fall short of their own plans).

More importantly I know about global battery capacity and how new capacity gets added and how much. I also know how much lithium, cobalt and nickel is mined and how much needs to be mined for the global industry.

You still believe that Tesla is some small player that is gone get crushed by the larger competition. Tesla has a higher market cap, easier time to raise cash, is the largest consumer of Li-Ion, has the largest long term supply contracts for materials, is close partner to all major battery producers (LG,CATL,Panasonic) and they are by far the most vertically integrated and they will soon add their own batteries to mix. In a 3-4 years Tesla will be one of the bigger battery producers in the world themselves.

We also know have a good idea how long it takes car makers to produce new vehicles and secure the supply chain. Look at 'all in on EV' GM, they are building a massive battery factory that by 2025 will be smaller then Giga Nevada is right now. In that same time Tesla plans to build another factory that will more then double or triple output of current Nevada and Giga Nevada will continue to grow as well.

Ford has no supply chain at all in North America and relies on LG in Poland. We know about how much output is planned from there and most of that is not for Ford. Ford has already realized that their idea of just 'buying what in the market' will limited them a huge amount.

Batteries can not be magically created, nor can lithium mines. We already know about all the battery factories that will go online and we know where they will send most of their supply. Nobody will catch up to Tesla in the next couple years.

TBH I’m surprised Musk hasn’t bought them out yet and “released” a limited edition Model 3 with a DeLorian body kit for like $500,000... if Cyan can release a Volvo P1800 for 500K and you usually need to provide the 50 year old P1800 for them to convert and tune there clearly is a market for these things.

I didn't realize that Volvo had such a rich history. That P1800 is gorgeous!

According to physics an ICE is most fuel efficient at 90% throttle and low RPM. At high RPM, or lower throttle positions you lose efficiency. So if you want maximum fuel efficiency you need to put the throttle to the floor, but stay at low RPMs. Thus the CVT is not doing the right thing for fuel efficiency. (though I'm not sure if the difference is worth measuring) Obviously the exact numbers varies a bit from engine…

When you put the pedal to the floor, you're not trying for efficiency, you're trying for power . Dropping to lower RPM for efficiency is what happens when you're done accelerating and ease up on the pedal. That's not what people complain about with CVTs. The complaints are about behavior and sound during acceleration, not after acceleration when you are merely cruising on low power output.

That might be you, but not me. I'm always trying for effiency. My cars never have the acceleration to make power interesting. I'm weird, but whatever.

Motor controllers are necessary with AC motors to supply the 3-phase AC that the motors need in sync with the motor's rotation. (DC motor controllers are simpler, but I don't think DC motors are used in any modern commercially-produced EV.) This generally requires some amount of software.

The motor generally has current and voltage and RPM and temperature limits, and the motor controller keeps everything within those limits. But the motor controller isn't there just for that reason, it's there because the motor couldn't function without it.

DC motors are different; those you could just literally replace your gas pedal with an on/off button and wire it straight from the battery to the motor. Not that that's a good idea.

The DeLorean story is insane. Mr. DeLorean tried to finance the company with literal briefcases of cocaine in hotel rooms. https://en.wikipedia.org/wiki/John_DeLorean#Arrest_and_trial https://www.youtube.com/watch?v=MCwKEnu5xSk

DeLorean was entrapped by the government.

Where's one find a reputable broker? I've wanted an isuzu npr elf for a long time. You can get them, but the prices seem vastly higher than they go for overseas.

Your shipment cost makes direct import seem down right sensible.
