I guess that's about right for that type of car...everyday street drivers, quite docile, really. Our "serious" normally aspirated cars go 0-60 in less than a second.

Charles, do they use a clutch in the electric motor drag applications?

I don't know if they do. One of my cars has one, the other doesn't. None of the electric motorcycles have clutches that I know of. AC Induction motors can run up to 10K+ RPM, hence no need to have more than one gear. A BLDC or DC motor will benefit from multiple gears, particularly when running lower voltage. Speed is dependent on voltage. The higher the voltage, he higher the RPM. If you want to do 200mph, you are going to need something in the range of 400 volts. If you are just putting around the golf course, then you can use under 100 volts.

For a drag application a slipper clutch would make sense for these types of vehicles, after all, you do have to

Electric has a pretty flat torque curve. About the same at 1 RPM as it is at 6,000 in a Tesla. It does start to drop off after that. You don't need to slip the clutch, matter of fact, the only time a clutch would be disengaged is during shifting. Let it slip and you are just wasting power. Takes a little getting use to.

So, are you saying the rear tires never spin?

Mine don't, both cars are front wheel drive. The other day I had the controller in the '93 turned all the way up and spun the front tires in third gear from a standstill. We have been joking about putting in a "4 stack" and seeing if we can make it wheelie in reverse. It is currently a "2 stack". A stack is a rotor / stator pair.

The '97 will only spin the front tires when the road is slick. It is limited to 180 amps. The '93 can burst to 400. Really fast cars can soak up a 1000 plus amps.
