Shifting without clutch is very easy but
takes 1.5 - 2 seconds.
Range40 Miles (64 Kilometers)
40 miles when batteries were healthy.
currently about 20 because a few batteries
are dying. Looking to replace pack.
Watt Hours/Mile550 Wh/Mile
I average 550 and it ranges from 300 to
800. I use power consumed at wall to
charge and subtract 27% for charger
losses to get total kwh input to
batteries. When measured on-board, I
get as low as 250 Whr/mile. I may run
more test to see if my charger losses is
greater than 27%.

I have many more changes I would like to make including
painting and adding more electronics. For now I am going to
enjoy the nice weather and drive the car as much as I can.
Once the weather gets cold enough, I will put the car back
in the garage and start working on it again.
