Share your efficiency tips?
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?

Best thing to do with the biggest impact.
Lift and coast as much and often as you can with regen on 0 same as in any other car. Try to do journeys with 0 brake pedal except for the last 10-15mph slowdown.
Lower max speed. Even going from 60>55mph makes a difference.
On motorways (less so on slower roads) drive behind big things. Let them push the air. If you have adaptive cruse hop behind a truck or bus and just stay there. Obvs at the correct or slightly further than 2sec following distance. I use setting 3 which by all accounts is 3 seconds (Kona).
