ZOE Range = (1110 / Speed) 1.95
– where Range is in km and Speed in km/hr, and Speed is from 30km/hr to 140km/hr
This equation is more accurate than the previous one, though significantly harder (actually virtually impossible) to do in your head! A fairly close approximation to it, at least in the range 50-130km/h, is to use (1050/speed)2; some people may be able to do that mentally.
None of these approximations are perfect, nor close-fitting across the whole range of speeds. In particular, the data show some irregularities in the range 70-110km/h. Therefore some further work on measuring energy consumption at different speeds would be beneficial.
Nevertheless, I will be returning soon to work on the My Renault ZOE Range Predictor app for Android, and for that I will use the new ‘official’ Range Rule above.
