I recently watched this video http://youtu.be/ubDItYYrtZ0
And i thought i would try this on the imiev for comparison sake.
I did 4 runs on a 7km mile stretch of the highway 2 at 80 km per hour and 2 at 110 km per hour. I did the runs in both direction to compensate for wind and elevation differences.
Results were 110/124 wh/km at 80 km per hour and 156/189 wh/km at 110 kph.
That gives an average of 117 wh/km at 80 kph and 172.5 wh/km at 110 kph.
So in the imiev driving at 110 kph vs 80 kph takes 47% more energy.
It was also interesting to note that at 80 km per hour the wind/elevation made a 13 % change vs at 111kph the difference was 21%.
Also interesting is that comparing with bjorns numbers for the leaf the imiev is 16 % more efficient at 80 kph and 13% more efficient at 110 kph.
I did this test with canion and included in the test is the acceleration from 65 kph on the freeway entrance on ramp. I mean i reset canion just as i was getting on the freeway.
Most of us already know this qualitatively but i thought it was nice to have some numbers.
One other interesting thing is the imiev speedo seems to be about 2.5 kmph slow compared to the gps. I guess mitsu did that to help out just a little bit more on the range of the car.
