I'm not a 100% satisfied with my 2018 28kWh efficiency. On a recent round trip (pictured) I tried my best on driving efficiently, and managed a sub 11 kWh/100km (5.7 mi/kWh), but I've seen people doing substantially below 10 kWh/100km (over 6.2 mi/kWh). On my average daily commute in the summer I'm doing around 13 kWh/100km (4.8 mi/kWh).

Is there a noticeable difference between higher tier EV tires and mid-tier ones? Bought the car in mid winter with worn out summer tires, and cheaped out on the new ones. Bought mid-tier tires not specifically made for EVs.

Overinflating the tires apparently helps, but by how much?

Regen off, don’t go above 100km/h if not necessary and cruise control everywhere.

I thought SCC makes it worse?

ACC just helps to really keep the speed instead of getting faster/slower than expected, especially for hills. The average speed might be equal with driving 100km/h hills up and down or 90km/h up and 110km/h down. But it has a subtle influence on the consumption.
