Cars need airspeed sensors for accurate range estimates. Wind makes a big difference at highway speeds and can change.

Yep. This range test was a round trip on the same road on the same day. So hopefully, if there was any tail wind one way, it would be a headwind the other way.

Tron, I am a FOO owner since September in Norway. On 22 inch rims I got the same range as you last weekend based on my odometer going south from Oslo to our summer place - mainly highway driving, however 535 km range going south and 505 km going back in 15 degrees C sunny weather north to Oslo. I capped my speed at 100 km/hr. (Elevation difference is 70 meters). In winter time going to the mountains for skiing range is between 410 and 430 km - obviously with much more elevation and on 20 inch winter tires. Thanks for your insight about the odometer not measuring the distance accurately. Is this the case with all FOOs or only yours? Also great to learn about the 13,9% energy loss between actually received into the battery vs delivered from your charger. Very educational and interesting indeed. I also had a Model Y LR before my FOO - and experienced better milage - my perception being that my FOO is materially more thirsty than the 20% that your comparison show. I very much liked your previous video on the FOO - sharing your experience as FOO owner versus the typical KZfaqr’s «reviews» which unfortunately have limited driving and owner experience with the vehicle and the software. Keep new videos coming, great value for us as FOO owners!

@@BjarneLauritzBull-Berg Very cool that you got the same range as me. As far as I understand from reading a little on the Internet, it seems like the odometer discrepancy is common, at least in USA with miles. Maybe it's better when it's in KM. I figured that was why the kWh/mi disappeared from the odometer page when we got 2.0. I never had a model Y myself, so I had to use numbers I could find on the Internet. I felt that Out of Spec Reviews always do a good job in their testing, so I figured I'd use their findings for comparison. Thanks for the support! 🫡✨

@pinguposse, I completely agree. Having the variables accounted for in regards to calculations would be handy. I can't imagine the spreadsheet that would entail all those variables. 😬🫣😂 Thanks for the support and well thought comment! ✨🫡💫

@dvdsteve40.... Well, it got me worried for several minutes... And miles. 😂😂😂🫣 Thanks for the comment and support. ✨🫡

@redstaper2414 It's awesome with free charging. A colleague of mine always charges his car with his portable charger when he rents an Air B&B. I hope Earth mode was the right choice. At least it's supposed to be the most efficient, since it only uses the front motor unless you really step on it, plus the A/C is in a more energy efficient mode. Fun and Hyper will always use both front and rear motors when accelerating, which should equate to a higher energy usage. On a different note, I read that Mercedes had come up with test results where automatic Regen, like one pedal driving, wasn't necessarily the most efficient way. This is because every time you either use or generate electricity, you also have a loss. So in some situations costing instead of Regen when lifting the foot from the accelerator should be beneficial. I don't know great this benefit is and, I'm guessing mainly if driving on roads with very little traffic. If you have to constantly change your speed to match other cars, I still think Regen is the better way. Thanks for the question and support! ✨🫡

That's a good question. I'm guessing you are talking trickle charging the 12V battery. As far as I understand, the main reason for the vampire drain of the high voltage battery, is because it has to maintain the 12V battery, which gets used to run if not all, at least the majority of all the accessories in the car, and many of those wake up now and then to suck the life out of the 12V battery. Earlier we lost 3%-4% a day, and currently I believe that the drain is about 1% a day. So in reality, your car should lose about 60% of the high voltage battery in 2 months. Having said that, I believe a trickle charge of the 12V battery should be able to keep the vampire drain to a absolute minimum. Personally, if I was leaving my Ocean in my garage for a couple of months, I'd probably choose to just leave it plugged in to my level 2 charger, and let the computer handle the distribution of energy. There is a chance that a trickle charge of the 12V battery, could send confusing signals to the computer, causing other problems, but I think the chances of this is very low though. I know that many people do use trickle chargers, as a remnant from software version 1.11 and older, and I think they do so without any issues. So a trickle charge of the 12V battery for a couple of months, would probably not be a bad idea.

The whole point of the test was realistic speeds. The test was not only good, but really good.
