All the EVs need to go to three significant digits like the ICE cars do when displaying MPG. My Sienna doesn’t show 21 mpg, but rather 20.5. That is 3 significant digits. There is a lot of slop in the two figures. Instead of displaying 2.9 miles /kw, it should be reporting 2.94, for example.Something I noticed upon looking more closely at the spread sheet is the Trip A information shows the kwh used rounded. For instance if the actual miles traveled is correct and the resulting mi/kwh is also correct you can calculate the actual kwh used more accurately. Then for example, dividing the total miles by the mi/kwh shown for GEWC you find that the kwh used was actually 9.6, not 10. Same for the other cars. For our "short" 43 mile trip this does make a difference. The 19" wheels with "All Season" tires clearly achieved better range than the 21" wheels with the "sticky" tires which was not a surprise. Lastly, with her extensive "one pedal" driving experience, GEWC is clearly better at modulating her speed to maximize range. So we did achieve results that are consistent with Lucid recommendations that if range is your most important consideration get the 19" wheels and if maximum handling is your most important consideration get the 21" wheels and performance tires. This was a first effort by our small sample team and I for one am pleased with the results. My DEP with 21" wheels is supposed to get 451 miles of range from its 118kwh battery, or 3.8 mi/kwh and I actually got 3.6 mi/kwh. I can chalk that up most likely to the uphill portions using more power than was gained through High Regen on the downhill portions or perhaps I just need to learn to drive more efficiently. In any case, I am more in the Hydbob camp and really enjoy driving the car hard and fast. We are talking about doing another run hopefully with more participants in the near future for a longer and perhaps less hilly second experiment.
