If I could drive all my miles on the flats near the coast, I might be able to get up to 4.5 or 4.6 m/kwh. Unfortunately I drive up and down a mountain every day and get 3.8 m/kwh most of the time. I suppose that if I lived in town, only used the surface streets, and kept my speed below 35 mph, 5.5 M/kwh might be possible. Of course it would take all fun out of driving.

1) 2 bubbles of acceleration maximum - Usually 5 or 6. When I'm trying for 5+ mi/kWh, 2-3.
2) keep it under 35MPH. Maybe under 30MPH - 35-45 city, 60-70 highway
3) neutral throttle as much as you can. - Yes
4) Regenerate if you need to sop - Yes
5) Friction braking as little as possible. - Yes
6) Flat or very gently sloping roads. - It's Missouri, not Kansas. Hillcountry galore.
7) 44 psi tires. - Yes

So basically, I'm doing it all wrong. :) In any case, the range meets my needs x2 (with the new battery), so I suppose it doesn't really matter.

2 bubbles of acceleration? Wow, you are a patient person. I try to limit myself to 4 but about once a day I need to merge to highway traffic or something and that won't cut it. Otherwise, 4 is fine for starts from red-lights, etc. I'm normally around 4.5 - 5.0 mi/kWh but much of my driving is in town or at 55mph.

I've got a 2015 S, just under 25,000 miles, still with 12 bars. I drive about 500 miles per month in the Chicago suburbs, my average speed is just under 25 mph.

I generally accelerate at 2 - 3 bubbles and I always use B mode. Tire pressure is 40 psi.

I rarely use the friction brakes, As much as traffic allows I let B mode slow me down for red lights and I put it in neutral when stopped.

It's a great car for me, I'm very happy with it!

In South East TX, I have experience quite a "cycle" in Ahrs from seasonal temp changes - and noticed that similar driving (without any heat or A/C) that the miles/kwh avg. does go up in spring/summer and down in the fall/winter:

Already up to over 54.5 Ahrs and expect further increases.
