UK-based YASA has just built a tiny electric motor that makes Tesla motors look like slackers, and this invention could potentially reshape the future of EVs
Had an ex-friend who was a motorhead arguing that electric motors will never beat ICE because they lack comparable torque. Look, I’m no mechanic, but I never got my head around that.
“You mean they don’t have enough torque to run a US destroyer?! Someone should call the Navy.”
Seriously, if you’ve played with even a tiny electric motor, provide DC, it goes, instantly. What could he have possibly been trying to say?
My parents had an original Prius and it was a weedy little car that made those two hippies really happy. If that was his only experience with electric cars I can see why he’d think that.
But the new ones are fucking rockets. I just don’t understand why they need all that. Can they make a cheaper one that’s got 300 horsepower?
It’s so sad, because we could make really great shitbox econo cars now. China, Japan and India are doing it, meanwhile in the U.S. we’re needing side-step assistance to climb into our tower-viewing position $80K+ ROADMASTER trucks and SUVs.
Nah, his complaint was lack of torque. Very strange, never got it. Figured he was repeating fossil fuel propaganda. But he was a motorhead!
And yes, energy density is the thing no one talks about when raging against fossil fuels. A gallon of refined gasoline packs insane energy. I’ve run my 5-gallon, crappy Harbor Freight generator all night into the morning, powering the camp, heaters and all, never came close to emptying it. Contrast that with a monster LIPO4 battery that died in 48-hours only powering LED lights. (Gotta admit, something weird happened there.)
Maybe just had torque confused with horsepower? That’s been the historical trade-off between gas and electric. Sure, its very easy to get an electric motor to jump into action. But it is comparatively difficult to generate the same amount of power with equivalent fuel density.

Much of which is lost to heat when combusted, which is the historical hang-up.
Not that batteries don’t have their own heating problems. But the benefit of batteries is that they’re an engineering problem we can solve with miniaturization, which we’ve become incredibly good at. We’re at a soft ceiling in terms of engine chemistry. Petroleum is about as refined as we’re going to get it. Combustion’s math is what it is. Improvements to the efficiency of modern engines have stalled out as an automotive tool, even to the point that a gas engine powering an electric capacitor in a hybrid yields performance improvements over the gas engine just spinning the wheels directly.

I think he was trying to admit he doesn’t know shit about electric motors.
Tool companies need to nerf electric motors in drills to prevent wrists from breaking.

Power sells, they can give that insane 0-60 sprint for very low cost, so it gets people to buy their product instead of a 6 liter V8.
I guess I’m really lamenting the death of the shitbox econo car.

There are places in the US that, instead of banning giant trucks, are banning Kei trucks.
I hate this country.
Usually the electric cars with a larger motor are also more efficient, since the motor does not have to run near its peak all the time.
I mean, the general appeal of ICE engines is the fuel, not the engine. Gasoline is generally more energy dense than lithium.

“EVs lack comparable torque to ICE” - guy in my rearview mirror
Electric motors don’t have a torque curve like ICE, which is why they don’t need a transmission. Those massive submarines run on electric motors.
