about US$80,000, including research, development and other associated costs
Well most of those costs go down (per car) if you keep making it, don't they?
As for total range:
The film [Who Killed the Electric Car] also showed that the company who had supplied batteries for EV1 had been suppressed from announcing the improved batteries that can double the range of EV1, and General Motors had sold the supplier's majority control share to an oil company. Towards the end of the film, an engineer explains that, as of the interview, lithium ion batteries, the same technology available in laptops, would have allowed the EV1 to be upgraded to a range of 300 miles per charge.

They had a fix. They sold the company with the patent to an oil company which immediately shut them down.
Chevy never wanted to make an electric car. They wanted to point to an electric car program as evidence they were trying to comply with anticipated CARB regulations. They also wanted to show that despite their best efforts they couldn't comply. And furthermore that people didn't want to buy them anyway.
But the engineers fucked up and made something useful, the salespeople fucked up by finding willing customers, and the customers fucked up by wanting them. Chevy literally took back the last cars under police escort, took them to a desert facility, and crushed them.
