On Saturday I did a mpg test on our EV on a 4.8 mile circuit of highway set up for 40 mph with no stops. I had a turn around that could be managed with out stops. I did the test without stopping then I did the same circuit with six stops using a timer to simulate six 30 second stops for lights. The results were startling with 175 mpg-e versus 143 mpg-e for stop and go driving.
The next day I repeated the test using out Ford F-150 and netted even more amazing results. 26.7 mpg v 17.2 mpg. I converted this data into watt hours per mile just so people could compare the two power train types. I did make one mistake in the video reporting a 109 mpg-e figure which was for the vehicle doing 55 mph, not 40 mph, but otherwise the video is good, and wasn't worth re-shooting.
These results show in this instance a 22% increase in energy consumption for stop and go driving over steady state driving in my EV while a 55% increase is shown for a IC Engine powered vehicle.
