| Nice car with a bad transmission and four cylinders. Mounted motor to transfer case and will run in low. Presently need 5 miles to work and have opportunity to charge there. Can add speed and range in future if needed -- vehicle's GVWR is 4,300 pounds. September 2007: I originally started with a 72 volt setup, but Seattle being a city of hills the 72 volt system was not up to the task. The car now runs 108 volts and will hold 20 mph for the final climb on my way home. The extra range from additional batteries is a nice benefit and acceleration is great. The entire system is under stressed. Nothing runs more than slightly warm to the touch. April 2008: Took the oportunity to upgrade batteries and system voltage. The car is pretty much finished and I have been very pleased with it. | |||||||||
