At 98 mph you might get ...
just guess 33 miles on flat highway.
That would be a whole 20 minutes.

based on 70 miles at 55mph (with AC on), 95mph would give you about 24 miles of range.

I recall them having a lot of trouble with it, but never heard the final outcome.

Does seem like a reasonable thing to consider though depending on how wide an RPM range is reasonable for these motors. Maybe the motor in the Leaf is made by Dremel.

Thank you, Carnac the Magnificent. :)

Seriously, how can you with 1 speed / range determine what the range will be at another? Given that range is (speed * 24kWh / Power) and power required to overcome drag is proportional to the cube of the speed, all we can say for sure is there is some quadratic equation (with a reciprocal term, 1/v) that would determine the reciprocal range under those conditions. Solving for such an equation would require 4 distinct speed points with all other variables being equal. 70 mi at 55mph would only give you 1 of those. One could just as easily guess that the equation is v * 24kWh / ((v - 55mph)**2)kW + 18.8 kW, which is 70.2 mi at 55mph and about 1.4 miles at 95mph.
