Is the Mach-E really 7 years behind Tesla?

[kdryden99]

According to this video the heat pump still uses resistive heaters for very cold temps. Not sure that they implemented it completely thus way though. Im curious to see Canadian and other northern feedback. How does the car get preconditioned heating in -30 with just a heat pump and no resistave heating?

I read the article that you referenced and while I have no doubt that there are certain circumstances where the heat pump will increase the Model Y's available range, I think you could argue that there will be more scenarios where the heat pump provides no advantage or even some where there is a range loss. In particular, the heat pump will offer no advantage when you are not using the heat at all. I would also say that if the temperature is very low, (below 10 degrees F,) A resistive heater will do just as well. The fact that you are carrying around an extra 40 lbs. of weight all of the time even when the heat is not being used can only hurt your range in warmer conditions.

A t bone steak should cost the same as chicken wing. Right that is the logic now right?

Only if they're both kept warm in the Frunk.

What makes you so sure that there is no resistive heater in the Model Y? The Munro videos, while both interesting and fun, do not go into enough detail to rule one out.

Because I know what components are in a Model Y.

Where do you get the weight from? The only extra components are valves to make it a heat pump, and you can delete the (heavy) HV liquid PTC. The Model Y's system has a lot fewer parts than many BEVs without heat pumps.

what would you rather have?

a heat pump? or a power On/Off button?

Why choose?

 

[Jolteon]

There is one in the heat pump patent. That does not mean it's in the vehicle at all.

On off Button for sure. A heat pump is virtually meaningless to me.

@trutolife27 is correct. Many of us live in very mild areas. In the winter it gets down to the low 40's / 5- 6 C in the mornings here. If I have an odd desire to head out while it's cold, that's what the preconditioning of the vehicle is for. That'll do fine for the 25-minute drive into town. I rarely have the heat or a/c on in any of our ICE cars right now. We're not alone.

Make it optional for mid-cycle revisions perhaps. I've fine with it as is.

Many of us do not live in mild areas, however. I never said I wanted a heat pump to be forced on people who don't want it.

But when I'm driving hundreds of miles a day in the snow, some extra range wouldn't go amiss.

Like the other video, this one is based off the patent. A page or two ago I linked to an interview with Elon where he addresses the initial cabin heating before the heat pump spins up. He describes a "local heating loop" inside the heat pump itself. What this consists of is not explained. It's either a resistive heater inside the heat pump, ar a small loop in the heat pump that heats the coolant quickly. Until someone tears down the heat pump all we can have is uninformed opinions on the subject. As far as continued heating past the initial few minutes, that's been covered here as well. The motors act as a resistive heater anytime both the heat pump and waste heat from the motors is insufficient to heat the car.

Don't you live in Hawaii? Yeah, you won't see a lot of efficiency gain with a heat pump! LOL.! What you would get out of the system is that it's simpler and less costly than the alternative. I'm sure that would be a prime motivator for Ford to go this route, which they most likely will.

Why do you think the heat pump/octovalve is heavier than the alternative? Watch the videos. Weight, cost and complexity are all reduced.

So that's why Ford buys their cars from outside suppliers pre-assembled, right. Got it, thanks.

No.

Ford also once ran coal and iron ore mines, timberlands, rubber plantations, a railroad, freighters, sawmills, blast furnaces, a glassworks, and more. Are you arguing they still should be?

Kyle's post on the model Y was a friend's in the Arizona desert....253 miles @70mph

InsideEvs drove 275 miles @70mph when they drove the MY in July
