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.

    So you get another set under the warranty? Maybe even twice?

    I wish! The tire shop said that the last set was damaged by excessive acceleration, so they wouldn't honor the warranty. I can't argue - our EV has over 600 horsepower and almost 900 lb-ft of torque, so my partner is just destroying those poor tires.

    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.
