Peri, If you have tires already well pumped (~45 PSI) and nothing is dragging then I found that tweaking the toe of the front wheels makes a lot of difference in the consumption (mi/kWh) which can easily make a difference of more than 10 miles per charge. My first Leaf had trouble allowing me even to get 3.7 mi/kWh and then I saw my current Leaf showing 4.9 kWh/mi so I checked the difference and all I could find was that this Leaf had a slight toe-out. I drive more freeway than the previous owner, but it still gives me close to 4.5 mi/kWh and the tweaked toe of my original Leaf also increased its efficiency. Cor.

Hi Lawrence, I've been paying attention to the kWh usage for various kinds of trips over the last several months. In summer, with reasonably careful driving, I could normally get better than 4 miles / kWh. Just like you ;) That was with no AC or other high aux loads. Now that we have cooler weather, it's maxing out around 2 miles / kWh. That's with heat and defrost on. Do you, or anyone, know if the Leaf miles / kWh meter (lower left of steering wheel) includes all the aux power or is it just the traction power? If the latter, then I would hypothesize that the battery is very sensitive to outdoor temperature. But, this seems extreme.
