The on-board Dolphin supports 120/240 volt charging for charging at 1kw/2kw rates. Mine also has the 6.6kw MagneCharger and can charge in 2 hours.

Range30 Miles (48 Kilometers)
30 miles is pretty much what one can expect with good batteries. One could do 40-45 miles, but that is really pushing it.

Right now with 6 year old used batteries I'm getting about 15 miles of range.
Watt Hours/Mile300 Wh/Mile
EV Miles
Current:12,000 Miles (19,308 Kilometers)
Seating Capacity5 adults, full trunk
Tires185-65 R14. Basically Prizm tires, low RR
Conversion TimeFactory conversion
Additional FeaturesThe car came with the following options:
Factory AC
50kw regen braking
Power steering
Power brakes
Factory heater

Having the AC and the power steering really makes the car simple to drive. The regen saves a lot on brake wear.
This was one of the Florida power and light Prizms. It's quite quick, drives like a nice solid Ford Tarus, and with the battery weight underneath the car it is extremely stable.

Note: I do know how to fix the Dolphin controllers and get these cars running. So if you're having problems with your car or truck and it has a "Dolphin" controller like the one in my car, please drop me a line and I can probably get it running. I also have a few spare controllers and processor boards.
