Interesting. So to summarize, they did a range test at 125 km/h (78 MPH), and got 335 km (208 miles) out of the AWD ER (270 mile EPA). Actually they said "we calculate", so I'm guessing they did something like a sample segment at that speed to get a good miles/kWh reading then extrapolated (which is what I plan to do too).

I like that they used a real high speed. 78 is perfect for my expected road trips, which will usually be at 75 or 80 here out west. 208 on an 88 kWh battery is 2.36 miles/kWh. And a 23% loss from EPA range. Not sure whether to cheer or gasp. Not sure if they did their test in Canada or at one of the events in Detroit or LA. In December, that would make a big difference in temps.

We knew there would be loss at high speed, and 78 MPH is higher than most test. So I suppose 23% loss isn't bad for that. It sounds like that's 0-100%. A realistic 10-80% range makes that 145 miles @ 78 MPH.
I just sent the author a tweet requesting the conditions he did the range testing. Hopefully he responds since I asked him nicely and being a fellow Canadian I hope he obliges ?

I'd be surprised if it stays that way. I agree that cutting the charging power to just 15 kW at 80% seems highly excessive. Almost ridiculous, in fact. Most of the charge curves we've seen for other vehicles that are capable of high-power charging tail off around 50 kW.

Even though most of the time people will surely stop charging by 80%, there are times where conditions could warrant an occasional 90% or even 100% fill while enroute. I expect that to improve in the production cars, either upon delivery, or a bit later via OTA.
When the epa number went from 270 to 250 mi (was hoping for 290 a least on a 100 KWh pack) cold weather range got tight. Numbers indicate at 90% charge I should make my Ottawa run down to the about -10 oF (yesterday and this morning -15 oF ). There is no way I am going to head into the barren wilderness in sub-zero temps unless sure and now not sure that will be the case unless at least 90% charge. With the throttling at 80% that appears to now leave me sitting at a charge for another hour in -10 oC hoping the sun doesn't go down (I will go for a walk for a few hours; possibly make friends with a bed ;)). Heard a lot about don't believe the numbers but initial indication is that numbers do not lie. Did you read the The first test: So good is Ford's new electric car (posted here already and credit due, thanks). Needs to be translated but excellent journalism and a good read.

Was looking for 1 ring to rule them all but initial indications appear that will need to be my next vehicle. I will enjoy learning with this one.
Kyle did say in the interview with @Mach E vlog that he didn't really want to comment on that efficiency because of the driving conditions he was in.
Been watching Kyle for awhile. Believe he had the car for a day, believe he has driven a few ev's, believe he is a smart man. I do not believe he would have just thrown out a number like that unless he watched it all day and was fairly confident the number was in the ball park. 45 oF 70 mph 2.1 Km/kw (185 mi, 129 at 80 to 10%) not even cold. Did you see the top gear vid?

Which video did you see 2.1 in, and where? I don't remember that in Kyle's drive video posted here.

I've gotta assume 2.1 was a typo, and he meant 3.1. If not, I'd be very curious to see where that number was pulled from.
No typo watch the vid.

Edit: Kyles review near the end; 11.2 mile run, but he knew what he would get prior to doing it I expect. Read the article for confirmation, top gear also. All are in line.

Go to 25:42 for the start then skip to 32:00 mark for results. Kyle does a 11mi run at 70mph in 45F rain with the computer reset for accuracy. It's not very scientific but it's what the car reported.

I think you lose 5-10% range with rain/wet roads.

That's prolly in line with all BEVs in those conditions. Full cabin heat, uphill 200 ft, 70mph for 10-11 miles, cold weather, into the wind (wind speed tbd). You can't escape that no matter what vehicle you are in.

The Top Gear video was revealing since like 12% of energy used was for cabin heating and another 11% for external heating (battery & motors?). Ideally a heat pump would be able to take advantage of that.

Thank you for providing the video. I'd checked the one posted in the videos thread and this one is longer. That one was only 7:44 and didn't have this in it. Trying to discuss sections of a video in a different thread is a PITA.

Maybe, but those aren't anywhere close to extreme conditions. They're pretty normal outside the Sun Belt. 45F is chilly but it's a typical December day for most of the country. Requiring a normal amount of cabin heat. And 200 ft of incline over 10 miles is pretty flat (a mere 0.37% grade). Wind is a question mark, but I didn't see any while he was standing next to the car at the start. The road was wet, but only mildly so.

I know those things all chip away at mileage, but those conditions weren't really bad at all. 2.1 makes that 128 miles of range from 10-80%. That's really creeping down there.

I guess the good news is that most people won't be doing long road trips in December weather. Still though. Marketing BEVs outside of California is going to be tougher.

45 oF can be a 15% diff (not including accessories so 2.5)? Temperature is not your friend. I do not want to get misunderstood. I am really looking forward to it, sounds like a comfortable vehicle that I want to try. I am always an early adopter to new tech and pay to much ;). These will get better and this one looks good, indicated to drive well and appears robust. Should have no problem fitting in. Waiting for more consumption info; it is interesting. Flaming Tesla on scalars not as interesting. Charging will get better (closer) is where I am hoping.

Agreed. I'm still getting mine (to pair with our Escape). This is more a point about BEVs in general. They look great rolling down the road in Sunny SoCal, but they're not for everybody. At least yet, anyway. Still a lot of issues/compromises that need to be improved for most of the populous before they will reach deep into the mainstream market.

Baby steps.

Our power generator (OPG) has jumped in and that is good news. Up here the Tesla charger spacing is worse. I am in a totally different boat and more like northern states. If the heat was on but not at 70 then another 10% on accessories 2.8? It is the cold that has the worse impact, just like the charging curve at 80% it drops right off, something that may not concern you at all? How cold does it get in the mountains? It is not range anxiety it is charger distance anxiety here right now; this is where things need to improve.

I think it's both. More chargers make many trips possible, but not necessarily preferable. Range does both. If you can make it all 200 miles without stopping, where you just "park it & forget it" plugged into an L2 charger at your destination, that's much easier than having to stop in the middle for 20 minutes to charge.

Range also allows you to go more places off the beaten path that don't have chargers.

Anything more helps, of course, but more chargers are only part of the solution. There's still aspects they don't fix.
