A friend of mine leased an EV1 back when and would have been happy to buy it, but GM crushed most of them. Just out of curiosity, I ran some calculations on what updating the EV1 would mean. Most of them had lead-acid batteries that weighed 594 kg and stored 18.7 Kwh. It had a range of 161 km. If you dropped the P85 battery into it, the weight would have gone down 54 kg and the range would go up to 732 km! That doesn't consider the improvements in motor or controller technologies.
