Since a couple months I have a very boring commute of 45 mi freeway each way. I am able to get between 4.5 and 5 mi/kWh with my 2012 LEAF which is heavier than OEM due to its 62 kWh battery from a 2019 LEAF. Also I carry several chargers and extension cords, even though my charging is 100% at home. This under following conditions: - speed is 55-60 mph continuous, preferably cruise control set to 55 - no air handling, too warm is handled by cracking open both passenger windows by an inch, cold is handled by dressing in layers and using steering wheel heater. Luckily this is SF Bay Area moderate weather year round. - tires at 42 psi - wheels aligned as close to 0 as I could get. Interesting detail here is that rear was good until an accident where a load of pipes fell off a truck behind me and crashed into the rear axle, slightly bending it. I had to shim the rear wheel hubs to get the wheels aligned again. I discovered the misalignment when the old tires started wearing uneven. The mileage I am getting is strong correlated to temperature. When it is warm, no problem to get just over 5 mi/kWh, when temps dip close to freezing it is a struggle to get over 4.5 The drive is extremely repeatable, to the point that I know traffic snarls and potholes to avoid by ODO day trip counter. Both ends are half a mile away from the freeway access, so there is no variation in route, only in the time of leaving on both sides, waiting for "no red on Google maps". Cor.
