When I look at the chart I see that the motor is 4 times larger than it needs to be!
If we adjust the chart for a motor 23% of the original size the torque figures drop by close to 23% (give or take), but the usage (g/kwh) figures stay much the same (give or take).
We then end up with this chart.
And then the gear ratios need changing so that 6th gear is slap bang in the lowest bsfc location (it becomes what fourth gear now is) and there are two lower gears to give some acceleration (which would still be absolutely piddling!)
