Yeah, it is pretty valid - same exact cars, same exact tires, same tire pressure and charge % and driving on the same road and captured on video.
I would say, pretty valid.
As for the EPA, the EPA does a calculation based on winter range and a special formula, hence why the WLTP didn't increase by that much. No heating.
As for the WLTP, this has been chewed a lot, I don't really think the WLTP numbers are correct, because the car has less capacity, but another topic altogether.
Oh yeah, a link to that test where they used the same exact cars with heater off and they achieved more range on the 2021?
Because I have another video, that confirms my findings too.
Check out this video where they had the setup wrong in the initial run. it is not as perfect as my test, because the heater was not completely off, but due to the wrong settings both heaters were probably pulling the same, hence the exact same consumption.
7:35 minute mark, 208 vs 204. After the cars warmed up and they changed the heat settings, then he tested around 10% advantage on 130km/h, much like in my tests.
Are you sure you own the car? Because if you were, you wouldn't be referring to other people's tests, but your own. So why don't you do the tests?!
You need 735Watt when the battery is warm, maybe in the best of best, absolut best of scenarios. This is also what I found out - warm battery, warm car - 700-900Watt. That is true.
But most certainly not when there is no heating, the cabin is cold, outside temperature is cold and the battery is cold. If I remember my numbers correctly, it was pulling about 2kW, same or similiar as the old one.
I can definetely confirm, after a whole winter season, very cold, that the heat pump in cold battery doesn't have any effect. ZERO! Especially in short commutes of around 15/20km. I was averaging my usual 230+Wh/km in stop and go as with my old car.
I can't find a time to cut the tests I have, but I have a few where I tested this against the 2019LR. I both tested the heat pump in camp mode and while driving.
Only and Only if! the cabin is warm, the battery has enough heat and the weather is not very cold - then you have an advantage of about 10% to 15% (15% in absolute perfect conditions)
But there is no efficiency gain in the motors whatsoever.
The second video above confirms my tests to the T.
So unless you can present your own findings and don't quote random videos you don't understand, then I suggest you let it be.
