### range loss compared

Posted:

**Tue Apr 23, 2019 10:14 am**My LEAF, when new, had 283 GIDs/22.0kWh available in LeafSpyPro. When I sold it at 4.5 years old and 34K miles, it had 249 GIDs/19.3kWh available. That's about a 12% loss (19.3/22.0) or a real world loss of about 11 miles (based upon 4.0 mi/kWh). It was still showing 12 bars.

(the GOM still gave some useless numbers like 98 or 105 or 110 miles range, but that's not because Nissan was trying to hide the real range from me)

My S 75D started at 257 miles range when brand new (charged to 100%). 2 years and 33K miles later, a 100% charge is now 249 miles. That 8 mile difference is somewhere under a 4% loss of rated range. IIRC, rated range is based upon 278 wh/mi (or 3.59 mi/kWh); it does seem about right, because the 75 has apparently 72.6kWh capacity available (257/72.6 = 3.53 mi/kWh). The rated range isn't a GOM - it's just math.

How close is the rated range to real driving? I can get as low as 240 wh/mi at 65 MPH on flat roads, but I almost never see that. Without heat, I usually see around 300-350 wh/mi on the highway. Here's a more typical drive -- a two hour segment between two SuperChargers at 70-75MPH:

My S has about the same number of miles as the my LEAF but over half the time frame. Most of the miles on the S have been from long trips with SuperCharging, whereas in the LEAF most of the miles were commuting 21 mi/day and charging at work at 30A to 100%. This is not really an apples-to-apples comparison.

The S has some range loss, but I don't think it's on the same level as my LEAF.
