What concerns me is that Nissan knows everyone wants to know range at higher speeds but they don't list that number, not even an estimate. It is very easy to get high numbers at low speeds, I wish they would at least discuss speeds at 65 MPH.
Range will depend on how you drive the car and the environment you drive it in. How quickly you accelerate to 65mph and what the weather conditions are at the time.
If I drive my Mitsubishi i-MiEV fast with rapid acceleration, I can normally guarantee being the fastest away from the lights, but my range can halve if I'm driving like that all the time.
If I drive my Mitsubishi i-MiEV gently and travel at speeds of up to around 55mph, I can exceed the published range for the car.

No AC/Heat, 60 km/h(37 mph) cruise : 220 km(137 miles)
Can someone make out the usable battery capacity using this ?
At 5 miles/kwh this would mean 27.4 kwh. I think 24 kwh is the usable capacity rather than total.
If you are doing a constant 37mph, you'd be doing an awful lot more than 5 miles/kWh. On a regular commute in my Mitsubishi i-MiEV, I'm getting around 6.5 miles per kWh. If I went to a test track and drove at a constant speed, I'd get an awful lot more than that.
Ignore the battery kWh figure, its a meaningless figure on its own: you really need to see figures for charging and discharging characteristics and temperature degradation performance to get a clearer picture of the range and performance of the car. I can't see Nissan publishing that information. If you want to know the economy of an electric car, get yourself a watt meter when you buy the car and measure it for yourself.
Learning how to drive an electric car economically takes some practice. It also helps to know exactly what the car is doing. For the REVA and G-Wiz electric cars, the owners club have reverse engineered the data output feed from the onboard computers to display what is actually going on with the car - the performance of each individual battery and the real time loadings on the battery pack. A couple of owners have even built a screen into their cars. Once you can see this information, it becomes easy to modify your driving habits to really increase your range.
From what I see of the Nissan dashboard, it doesn't quite give you enough information to do this in the LEAF. It will be interesting to see how long it is before somebody hacks the computer feed. :lol:
