InstrumentationAmp-Hour meter from Solectria. You can use the a-hr meter to figure the amps by timing the amp-hour change, then dividing by the time. For instance:
.05 a-hr/(5 seconds * (1/3600 HR/SEC))= 36 AMPS. Must keep track of the units.
Top Speed70 MPH (112 KPH)
AccelerationI mostly drive in economy mode, where the amps to the motor is limited.
Range50 Miles (80 Kilometers)
The specifications say 45-50 miles if speed < 35 mph. With a new set of batteries, I did a range test of 57.5 miles. I quit when the top speed was no more than 25 MPH. The test speed was < 40 MPH.
Watt Hours/Mile220 Wh/Mile
The challenge is to minimize Watt-Hours/mile. In the range test above, the a-hr meter registered 62 a-hr for 57.8 miles traveled. watt-hr/mile = 62*156/57.5 = 168. This was one test. But over a years time, I average 220 watt-hr / mile.

Additional FeaturesI recently got the air conditioning going. It draws about 7 amps. This equates to 1.5 HP. This compares to 36 amps driving current at 30 MPH.
With the exception of having to replace batteries, my carbon footprint is "0"*, as my power company is "renewableles only". And this is with 12 year old technology. Come on Detroit!

*Not quite true, in the sense that the batteries, a consumable, have a carbon footprint, as does the car's manufacture.
