I would suspect a car that weighed around 2000-2200 pounds, with a more typical Cd of around .28-.32 and with low RR tires the range on a 10kw pack would be perhaps 35 city, only 25 high way miles.
It is worth the effort to drive the tires directly without a transmission because you lose some serious energy there.
If you are using an existing car, due everything possible to reduce weight, improve aero etc. Look up car designs that have low Cd and see if you can emulate that exterior.
Steal ideas where ever you can. Look up the Aptera, Probe V, LoReMo.
LoReMo has an interesting idea I plan to put in my car: no side doors, it uses a front hood/windshield door that lifts up. It saves a lot of weight because you can design the side of the car to be much stronger with less weight.
Good luck!

What's the story (especially as regards NYS, since you're a fellow NY'er) with custom vehicles? How far can one go in making a custom car, and what are the legal requirements to getting it on the road?
