I did a run from Toronto to Barrie on a 90% SOC at 0 degrees C on 20-in wheels (about 240 km) and had to stop to charge! When there isn't much traffic, there's practically no regeneration and the range gets consumed fast. Also, you have to keep the air on throughout to prevent fogging the windows, so there's no way to economize on range except to drive slowly, which is no fun at all.I did a 100km (60 mile) run to Toronto and back on Sunday with clear roads and +1 degree Celsius at 130km/h in both directions without slowing down too often and used approximately 33kwh/100 kms each way. I got home with around 15% battery left which would translate into a range of around 270kms which isn’t great. I run my 22” wheels at 37psi which probably adds a lot of drag. If I pumped them back up to 47psi I bet you I might see closer to the 29kwh/100 kms you mention.
