Ok, I just did a test driving about 30 miles in each direction at a pretty constant 70 mph with tires at 44 PSI (outside temp was between 55 and 60F).
Results were 3.3-3.4 in each direction per the dash. A bit lower based on readings in Leafspy, but timing of readings might explain that.
At 58.4 usable kilowatts, that puts range at 192 miles - 198 miles, so pretty close to what Tom measured when you include some buffer.
This did make me realize how much efficiency mgmt I had been doing on my long driving runs in terms of staying with traffic and letting speed drift to compensate for terrain or wind.
Could someone with an S out there within a few hundred feet of sea level try the same. I am curious if the wheel size makes any difference at 70mph. I would say that tire pressure didn't do much at that speed.
I did gps check the speedometer at 70 mph, and it was pretty much right on.
Was watching the out of spec motoring videos for range tests. It looks like the Bolt gets almost the exact same efficiency as the Leaf Plus, though due to bigger battery gets another 20-30 miles more range (makes sense 7kWh x 3.4 = 23-24 miles) .
Interesting that the SR+ with Aero wheels was at about 220 watts per mile (or about 4.5 miles/kWh in perfect weather) at 68-70 mph, but with 20 inch wheels that dropped to 300 watts per mile, or ... 3.33 miles/kWh. This might give me hope that with an efficient wheel set, the Leaf Plus could be brought up to 3.7 or higher. Moving to 16" rims with flat covers would help. Lowering the car an inch would help as well. Other inexpensive ideas?
