Just completed a 350 mile weekend round trip from Portland to central Oregon (Bend). Route is along US26 up the side of Mount Hood (lots of elevation to climb then descend). Weather was clear and nice but cold (high of 40°, low of 21° I would say average was 35°). Two people and weekend bags going over from Portland, then four people and lots of suitcases (both trunks were completely full). I know this isn't breaking new ground for many of you but this was my first long range trip in cold weather, with my 21" summer tires as well. What did I learn? (a) on the Energy app, it works best for me to select 30 miles and Average (not instant). Why: because the up hill excess consumption and downhill regeneration smooth out the miles remaining display so passengers (maybe even the driver!) don't freak out at the over- and under- estimated miles to empty. (b) from my around-town experiences I discount about 20% off the Rated miles full (range) charge miles due to battery pack heating and cabin heat. Temp at 71° and two seat heaters on #1, also running the fan on #3 or #4 to keep the windows from fogging. So my initial 'guestimate' was the 264 mile Rated really would only be about 220 miles usable. Wanted to have at least 10% reserve so a 200 mile trip should be possible. (c) On the way over averaged 395 Wh/mi over the 170 miles driven, on return it was 355 Wh/mi same distance. (d) watching the energy app Average line (comparing to the energy budget) I knew that to achieve the Rated miles I could target driving a bit slower or at least less aggressive on the accelerator to get my average down close to the budget. (e) Ended the trip over with 30 rated miles showing (so that is about 15 less than my 'guesstimate') and the trip back with 49 showing (about 5 more than guesstimate. (f) yes cruise control really does lower energy consumption even going up/down hills. You can see how much less jagged the energy line is after 10-20 miles of cruise driving. So I am learning to trust my mental math and to reasonably assure my spouse we won't run out of miles just because the Instant display says we have only 20 mile remaining yet we have 80 miles to go! In short, I am becoming a believer in Rated miles provided you discount for environment (heat/cold) and make reasonable attempts to reduce acceleration and/or speed to get you 30-mile Average energy close to the Rated line.
