Hi dana,
The all Electric ePrius is a loving project by Steve at this point and not practical quite yet. However, he keeps tinkering with it. When Rob from Plug in Supply came, they hooked up a 10 KWH battery supply and I believe their range was about 35 miles. The car has nice pick up and a top speed of 52. My PHEV can go all electric as I have the same basic kit with lead batteries. I max out about 10 miles but I have a gas hybrid back up! Steve's ePrius has NO GAS ENGINE!! That is really cool.
Steve told me that they have recenlty made a new computer hack and can go up to 70 mph with the new kits coming out but I don't think he has done that yet, but he will. That will make them a pretty reasonable electric car. Find a salvage Prius with no motor, add Lithium batteries and presto, for about 12,000.00 you have a real electric car not one of those NEV plastic toys.
I thought of buying an EV but didn't see the advantage over my PHEV that can run EV. I reallly scare McDonald's employess when I drive up in "stealth" mode, which is what Plug in Suplly calls EV.
