Mustang: Electric Muscle Car

[Don]

PHOTO CAPTION: The Ronaele Mustang 300EV sports a 300 hp electric drive train with 1,000 pounds of torque. For around $80,000 the company will convert any 2005-2008 Ford Mustang, replacing its gasoline-engine components, including its transmission. The finished package actually ends up weighing less than the original and has better weight distribution.

Kadie will be installing the 300 hp electric drive system in HST Automotive's signature Carroll Shelby Cobra 427s.

How far can it possibly go between "fill ups"?

The cool thing should be the constant torque (1000 ft-lbs) over the intire speed range!!

But no tail pipe sounds is weird. Maybe one could record the real one and put big speakers in the rear.

Mike,

The 1000 ft-lbs is probably the peak torque which normally occurs at 0 rpm off the line with electric motors. The torque is directly related to amperage and, just like an electric drill, the motor draws the most amperage at stall and produces the greatest torque at this time. Perfect for acceleration off the line. An electric motor naturally has an almost ideal torque curve, maintained quite well into upper rpms, though, because of actual load.

The only way that the peak torque can occur at greater than 0 rpm is if applied voltage is suddenly deliberately increased to drive more amps through the motor. As motors gain rpm, they produce a back EMF (voltage) because they are, in effect, also a generator since the armature constitutes windings turning in a magnetic field.

When an electric motor is running freely at its top rpm, the back EMF matches the front applied voltage and, theoretically no amperage flows. In reality some amperage flows because bearing and other small frictions create a slight load that almost imperceptably slows the motor which in turn creates a slight imbalance of applied-voltage vs back-EMF and, in turn, a slight amp drain. So neutral coasting draws very little or no power. Or the back EMF recharges the battery during forced coasting. Perfect for acceleration, perfect for coasting. Too bad batteries still suck.

Is it legal to have a 100 mile long extension cord hooked to the car?

What we need is wireless power. I am sure if you google it, you will find folks trying.

Sort of off the subject, but did you see where the guy in Southern Calif. sued his neighbors to make them cut down some of their trees because they were blocking the sunlight to his new Solar Panels. And they had to cut down a couple of them because of some ancient law the judge found citing everyone's right to the sunlight. Now be warned, if I hear of any of you using any of my sunlight I will sue.

Wes, thanks for the explanation, almost like the difference between a SB & a BB.

Wonder if the Cobra with an electric motor will still be a replica/kit car or ?

You are welcome and thanks for the link. Perhaps the future will have small-armature vs big-armature arguments. The old torque vs rpm controversy.

Maybe a popular hot electric will be the subject of a knock-off 40 years later. Then there will be those guys that used to know somebody that owned one.
