quote: Because weight doesn’t change with speed, the drag force due to weight doesn’t change with speed.
quote: Therefore the power consumed due to weight scales linearly with velocity or is proportional to mass times velocity.
quote: The drag force due to aero drag scales with the square of velocity. Therefore the power consumed due to velocity (aero drag) scales with the cube of speed or is proportional to velocity cubed.
quote: Adding the results of the linear function and the cube function creates a third function in which mass and velocity still feature separately. That third function is NOT proportional to the square of speed. Mass times velocity is NOT a constant and so cannot be factored out along with the other constants when figuring out proportionality. I’m not wrong about this.
quote: That went straight over your head. The Tesla’s weight and tires will result in a rolling resistance of 56lb force. If you think that is insignificant to the point of being practically zero when compared to aero drag then what else can I say. Either you can’t understand or you won’t understand and neither of these makes you look good.
quote: An EV is not like one of your model aircraft and the correct terminology is Motor controller specifically so people like you won’t become confused. I posted this on the 4/16/2014 in this thread so it is what I have been saying all long.
quote: The advantage of full torque from zero is not having to have a clutch (or torque converter).The advantage is not having to have a clutch. It’s a mechanical simplification.
quote: In the case of Tesla the range of the motor is so broad that it also doesn’t need a gearbox and can make do with a single reduction ratio. A further mechanical simplification. The net result of this is lower weight better reliability and reduced cost.
quote: So if torque is not consumed and power is consumed and power is torque x RPM then really it is just RPM that is being consumed?? LOL. You’re funny.
quote: All that and you still haven’t said were torque in an idling engine is being transferred to.
