You will notice that the graph does not clarify driving styles from the test data (only "Range") and does not show worst case, only Best and Average. Very misleading for those who don't live in sub zero weather.
Now I think that you are missing my point.
The whole purpose of the study was to document the average or typical experience of driving the Leaf in cold weather, not to warn drivers that under, as you put it, "worst case" conditions the numbers would be different. Of course, they would be different. Worst case scenarios provide worse MPG results than advertised with ICE cars as well. An ICE car may have an EPA mileage of 30 for highway travel, but when driving up a grade against a head wind while pulling a boat drivers will certainly get a lot less than 30 MPG. So what? The point of an MPG rating is not to capture all possible scenarios, including the worst-case ones, but to offer the public a reasonable estimate of the MPG under "normal" driving conditions.
Finally, it is unclear to me how your example of driving 32 miles in a fully loaded Leaf, stopping for 4 hours, and then having 27 miles of range remaining supports the poster's claim of 25 miles of stop/start range. Maybe I misunderstood, but 32+27=59. What exactly were you trying to show with this example?
Not sure you are posting here in good faith?
The study is not really the point for extreme cold weather drivers. I and the other person are not idiots and I sure the other person I am corroborating has a much better story for warmer weather. I happen to be in the top 5,000 in CarWings for the last 2 months, Platinum and Gold so I know what I am talking about just a bit.
My point was purely the temperature, temperature, temperature is the issue. Yes also having a gasoline station with indoor warm facilities is an advantage the ICE driving world has, I have not abandoned that world either. My Example incorporated the temperature and its likely potential to change drastically enough that my ICE world driving habits put me and my family into a safety "issue". I had to go off route and seek electricity at 2 degrees F, yes it was 60 miles off the Lake from Downtown Chicago and not densely populated. The above numbers of making a 2*32 mile leg trip totaling 64 miles only occurred because of an additional 7-8 kWh? emergency charge giving me 37 on the GOM an increase of 20 miles on the GOM.
Full charge 15 degrees showed 75 miles (GOM) - 32 miles later and return to car after 4 hours now 2 degrees shows 27 miles on GOM - 2 miles later and now 0 degrees the GOM goes to 20 miles. Drive 2 miles out of normal path to Nissan Dealer we did not know of and if access to charger was possible after hours. Arrive Nissan dealer and plug up, crisis averted GOM reads 17 at start and we discuss trusting what number we need to get to on the GOM after an hour plus of sitting in the car charging and running heat so as not to freeze to death. We decided 37 was our target and left at that point - Leg home now was estimated at 27 miles. Arrived back home almost midnight with 5 on GOM. Everybody's feet were very cold, but seat warmers were on.
Therefore range with an extra charge on this multi leg trip with 4 hours of cold bath was 62+2 miles = 64
Subtract the emergency charge and preconditioning of 20+5 miles =(64-25) = 39 miles range on full charge at 15 degrees leg one and sub zero leg two. Sorry for sparing the details on the first account but that was not my desire, it was to agree with the other poster about really cold real world observations. Look at the color dots at -15F and how there are few other colors in this area of the graph.
These results were on roads doing 35-45, no highway driving, Eco mode, and usual 2 dot, never past 3 dots acceleration. If you were to have gone on the highway and drove 60 mph this range of 39 would have gone to best case low 30's!!
We are painting that end of the graph more clearly than the few dots there on on this very sub zero end. Cannot tell you how many data points are represented on the line in the far left very cold region? Again the graph is not the real point. Winter Mode in extreme weather the GOM can become the DOM - Death-O-Meter. There are not enough public charging stations yet (the reason this post is in this topic) Please plan ahead - I know I will.
