I wonder if we'll ever get enough standardization across EVs so people can start doing the electric equivalent of an LS swap.
I could see this being done on a Slate truck, along with an auxiliary EV battery bolted in the back.

It's more about the batteries than the motor. You can make a motor that sucks down as much power as you want. The battery can't necessarily provide that without damage.
Hopefully solid-state batteries (once their production manages to ramp up to consumer vehicle scale) could allow for higher capacity and power delivery without the limitations or safety risks of current battery tech.
I mean, I guess. Power output isn't what I'm really hoping for on new battery tech. What we have is perfectly capable of 0-60 times that only thoroughbred performance street cars can meet (like Ariel Atom territory), and the top speed is plenty.
Once you're putting down 500hp, tires start to become a limiting factor. The torque that goes behind that number can stress the limit on all but the largest tires with the stickiest compounds.
Safety, range, and weight reduction of new battery tech are great, though.
Yep, I have an EV and the way my partner drove it just eats through tires. We're talking about $1.5k, 50k mile warranty tires being replaced at 20-25k because someone liked to pretend they're a fucking astronaut on launch day.
Not bitter.
I also have an EV and tires need changing way faster, for sure. The original tires were replaced only after 2 years, but I just love taking off on that animal, so, I'll be wasting more money on tires.

Current capacity, safety and power delivery are fine for most purposes, really.
LFP batteries really solved battery fires - they can't produce their own oxygen like older NMC batteries, so they just get really hot and die instead of going off like fireworks.
Once you get past 300 miles, you're pushing the limits of the average bladder and you need to stop before the car does.
With current electric trucks, if you're doing some city driving and plug the truck in when you take a break, a truck driver will run out of hours before the truck runs out of range.
Once I figured out it was an axial flux prototype motor this whole article made sense.

Anything but metric!
Horsepower is a pretty standard way to advertise things in the automotive industry…

Ah they're rating motors like they used to rate speakers?

Car engines, for probably the past 100 years, have always been advertised based on their peak power rating, not what they can produce continuously. Cars are not designed to have their accelerator pedals floored for hours on end, nor is this even possible to do, as you'd eventually hit a curve and need to slow down.
This is especially the case for high performance vehicles, which usually have more demanding maintenance requirements just from normal operation, let alone from being abused like that.

I'm gonna slap one on my fixie.
Having a powerful motor is nice, but you still have to power it.
Easy! Just make this:
With this:
I'm gonna slap two on my fixie.
This, in a folding, commuter e-bike.
*guns throttle* Tires and tube liquify, blast apart, rim rapidly grinds to nothing against the pavement, spokes rocket in all directions. Onlookers remark: "pretty cool way to go out..." And then give the 🤘 hand gesture
I was going to shit all over this thing, but if it can do ~500hp continuously that's awesome. Wonder what kind of efficiency it has and what the cooling requirements are. That low weight puts us back into unsprung wheel motor territory, especially if it scales down well.
