Hub motors are a party trick. They will never reach mass market in a car.

This is already pretty close to how many EVs are designed.

Except for the fact that that much power would need massive batteries. So your thin small battery would be dead the first time you mashed the peddle to the floor

YMCA NASA colab would've been lit though

What could he have possibly been trying to say?

I mean, the general appeal of ICE engines is the fuel, not the engine. Gasoline is generally more energy dense than lithium.

I think he was trying to admit he doesn't know shit about electric motors.

"EVs lack comparable torque to ICE" - guy in my rearview mirror

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?

He was trying to say that he spent too much time in a media bubble disconnected from reality.

Dunno, I feel every rev head knew about that evs have no torque curve and plenty of it. The concern to me head always been weight and range when on track. EVs are great in straight line, but have a lot more momentum in corners. They generally have narrower tires as well, which is great for range, but poor for grip

If it's a Corgi, I would estimate the power output at .1 horsepower max. But if it's a small dog the size of a large dog, then that's something entirely different.

A dog's power output comes from its muscle mass, which for a healthy dog is about 45% of its total body weight. This gives our 28-pound dog roughly 12.57 lbs (or 5.7 kg) of muscle.

Studies of animal muscle show that the peak power output of vertebrate muscle tissue during a short, explosive burst (like a jump or the start of a sprint) is around 100 to 200 watts per kilogram of muscle.

Now we can estimate the dog's peak power:

• Low estimate: 5.7 kg of muscle x 100 W/kg = 570 watts
• High estimate: 5.7 kg of muscle x 200 W/kg = 1140 watts

Converting these figures to horsepower (1 horsepower = 746 watts):

• Low estimate: 570 W / 746 ≈ 0.76 horsepower
• High estimate: 1140 W / 746 ≈ 1.5 horsepower

So, a small 28-pound dog might be able to generate a peak power of around 0.75 to 1.5 horsepower for a very brief moment.

So this YASA motor is somewhere between 670 and 1,340 times more powerful than the dog it's being compared to in weight. That's some jaw-dropping power output.

This motor weighs 12.7 kilograms and has 1000hp. How much does a comparable motor weigh?

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.

Ah happy days. I've not heard PMPO in so long!

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 peddles 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.
