Unscientifically..... - my car was doing about 5.5km/kW at about 38PSI.... - upped it to 45PSI and I now get 6.6km/kW.
Gosh, it's dependent on a number of things. I can get 100kms on a smooth flat road, like the Hauraki plains, about 80 on the poor, hilly roads of the far north and about 110 around Auckland.
I get about 90-95km on a 100% charge at open road speeds.
105 km is the most I've done, with a bar or two left at that point. So probably 120 km for round town driving with minimal hills
I get about 90km/charge - But that hilly as - driving with the aircon on
Some days I get 75-80 and others I get 110, but most often between 80-90, I mostly use flat open roads.
