That's what I thought. But it doesn't matter how many times I check my math. With that kind of air drag the Leaf should go much further than 100 miles. As much as 5 times further
.
Simply a couple of kilowatts at 100kph is nothing. I'd expect more like 10. Maybe I'm doing the math wrong, but I can't see where.
Math aside, it would seem to me that a boat tail, wheel skirts and some air dams in front of the wheels along with some slower-than-usual driving ought to double the current range.
Edit:
I see where I made the mistake. I used a CdA number instead of actual area. The no way a Leaf is going to have a frontal area of .7m^2. It's 2.2297m^2. So it takes about 8.5kW just to push the Leaf through the air at 100kph. I'd like to see what kind of Cd is possible on a Leaf with mods. But for now, I'm glad I figured it out.
