Wow, that would make a sweet ride. I personally would have 156 volts for more Zoom Zoom factor, but I don't think your calcs are too off.

Some of those S-10s and pickups are in the 4000 lbs range and using 9" ADC, so it cant bee too bad. My 9" ADC barely gets warm in my 3000 lbs Civic, assuming I keep those RPMs up.

My passat is 4700 lbs, and i easily get 300wh/mi. I can also easily break 100mph. I think a larger car is an advantage when it comes to top speed, since you can carry more batteries, and drag is about the same as a little car.

Weight makes little difference it range/efficiency at steady state cruising speeds over 35 mph.

Weight makes a huge difference in stop and go city traffic, and on all of your car's performance parameters(barring top speed).

Whether a WarP 9" will give you the performance you want depends on three things:

1) Your performance expectations
2) Your choice of controller
3) Your choice of battery

A WarP 9" setup with 156V and a Zilla 1k will give a 3600 lb car a 10 second 0-60 mph time, provided you battery doesn't sag below 120V at 1000A.

No reason it won't work just fine. I would add a good blower on the motor and I agree with SGC to go with a bit higher voltage.
