Drove Vancouver to Edmonds, WA (village N-side of Seattle) Monday 25th and back Tuesday 26th. Interstate 5 both ways, with short detour to La Connor (charging & sightseeing & clam chowder) on way back north. Consumption 17.2 kWh/100 km south-bound and 15.0 kWh/100 km north-bound. Used NORMAL MODE going S and ECO MODE going N. Dry road, except for very brief sprinkles of rain and wet road south-bound. Speed usually 10 km per hour over posted speed limit; 106 kph in 60 mph zones and 122 kph in 70 mph zones. When necessary, brief bursts to 135 kph (84 mph). Five knot southerly wind south-bound and 5-kt westerly north-bound. Wind probably insignificant effect on consumption north-bound, but slightly increasing it south-bound. Tires: all-weather Nokian WRG4 at 36 pounds p.s.i.
Lessons learned: Density of charging station network is still inadequate for long-distance travel in non-Tesla electric cars. DCFC (direct current fast charge) stations are essential, but they are still few and far between, even on Interstate 5. I did discover that new DCFC plugs will be available in early April on Lakeaway Drive, east side of I-5 in Bellingham. This will be good news for American Konas heading for the border and for Canucks shopping in Bellingham. The Kona proved to be a comfortable car for a 200 kilometer road trip. A bonus: the HUD on my Canadian car on US roads showed speed limits converted to kilometers per hour. Nice!
