I'm fascinating how it works. I own an electrical vehicle. I take it fully loaded (5 passengers with junk in trunk) uphill in SF. Very steep hill. I don't notice any performance changes. And I don't hear any increase noise from the engine.
Maybe it's a bad comparison, but when I put the 200 lbs patient on the hospital bed and elevating the bed, the motor is working smooth. When I put 400 lbs patient the motor working slower and sounds like its choking.
With electric car I don't see that difference. Is it because a motor is 100s times more stronger, or it works differently through the differential and transmission?
