Or would be funny with him popping up in the corner. Or make a stuffed Sandy munro doll (like an elf on a shelf) and randomly place him on things you talk about when he’s not there. Then you can sell Sandy dolls!! Haha. I can see Sandy eyes rolling!!

Ben, Cory, Sandy and all your behind the scene staff is top notch. You all are relatable people and that is what makes these videos so popular. The focus is on the technical overview and details like an engineer or mechanic, and not on being slick and doing a business school type verbose but hollow presentation. Thank you to Monroe and Associates for educating and informing us. I eagerly look forward to your videos.

[@rick67hou]

@@2hedz77 heat pumps are almost totally useless in warmer climates as they'd never be used, therefore, unnecessary weight. But you never knew where a car would end up, so you included it with every car anyway.

[@Teslavangelist]

[@FlorentHenry]

I am not sure you made it clear for everybody why heat pumps are more efficient than resistors. Resistors convert electricity to heat at 100% efficiency. Heat pumps move a fluid and change its phase in different places (well detailed in the video). This change of phase (liquid/gas) allows heat to be moved from one place to another using Carnot's principles. Using the same quantity of electricity, you can move ~3 times more heat energy, making it about 300% efficient (compared to resistors that will convert electricity to heat, which requires energy conservation and limits efficiency to 100%).

[@seasong7655]

The resistive heating is just 100% efficient not "close to 100%". There's nothing else the electricity turns into besides heat.

[@FlorentHenry]

@@seasong7655 Correct, fixed

[@CAEngineer]

nice explanation, thanks :)

[@ohger1]

Correct, but more simply, the plus 100% efficiency of heat pumps comes from "stealing" heat out of the ambient air. Any air that's above absolute zero has latent heat to be scavenged.

[@tommanseau6277]

All you need to make us feel like Sandy was there is a button you can press & it says: 1. Ugh, too many fasteners (exasperated tone) 2. Hello boys and girls, keep tipping those cashiers 3. What is going on here... 4. I don't like it, too much stuff. Less stuff, more elegant. (or something to that effect) 5. That's actually nice, really nice (surprised tone) 6. This, this right here makes me happy! I think that sums it up. But seriously, This format works well. Each person playing to their strengths and explaining enough for the average person to be able to appreciate what's going on. Thank you

[@MarkXHolland]

What about, 'The best doodad is no doodad. And whatnot.'

[@morrisg]

Good job, Cory & Ben! Only thing missing for me was a comment on relative efficiency of PTC vs Heat Pump. Heat pumps over their working range are 2x to 5x more efficient than PTC at putting heat where you need it. When it gets very cold and outside the range of the heat pump's design numbers then an external source of heat is needed. In a Tesla this is done by running the electric motors inefficiently causing them to heat up the liquid coolant flowing through them to supply the heat to the heat pump. TeslaBjorn's testing has show this is about 7kw of heating from the motors.

Funny comment. These are brand new not driven vehicles so they are clean plus there are a lot more folks around doing the work. I used to work doing all sorts of things at a Mercedes dealer back in the 1973-74 period. There were many days that my clothing never got soiled so, yup no real amounts of grease and fluids that are such a mess. Still even though they stay clean. Remember they are not working on an ICE engine which by its nature is a mess. Appreciate your perspective

[@TheTrendyPixel]

You both did great, good stuff guys!

[@ProfessorHamer]

I think you could have explained the difference in "efficiency" since some will be confused that a PTC heater is essentially 100% efficient, but a heat pump can have a greater than 100% "efficiency" because it is refrigerating the outside air, moving heat from cold air to the warm coolant. I.e the heat moved is greater than the work done by the compressor.

[@tschuuuls486]

I like this "format." Clear and concise explanations presented in an orderly manner. Just add Sandy for some occasional insights and comments and it'll be great. As always, interesting and informative. Keep it coming.

[@WSDFirm]

I love the detail and explanation. I always like the compare and contrast aspect that you did in the latter part of this video. I did miss Sandy’s “disdain” when he thinks something could be improved. No one could or should copy Sandy. Excellent video! PS Question: Tesla iterates and changes and improves manufacturing without waiting for a “model year change.” They certainly did in the early days of the Model 3. A good video or episode for your upcoming Plaid road trip might be meeting people with newer Mach-Es and see if they are iterating if the car is manufactured a few months after the one you are tearing down. At least on the parts, you can see with a flashlight 🔦 Thanks again.

Nice clear explanation. Good educational content! Ford has a *lot* of engineering headroom to reduce energy consumption, reduce weight, and improve range on the Mach-E. I hope they/re listening.

[@carholic-sz3qv]

They are already improving on everything and fortunately the base is already here.

[@dzerres]

But ask yourself "why"? Why should they be "watching" and "listening" at this point? They had since 2012 to watch Tesla produce engineering advances and still their first effort, the Mach-E, is basically the same ICE product Ford has been producing for the 100 years but now they slapped a battery under the floorboard. That's just lazy.

[@carholic-sz3qv]

@@dzerres please gtfo with all that negativity, there is always room for improvement and there is always a beginning to something. Bmw for example was a pioneer with big castings and they built one of the world's largest carbon fiber factory to make cars lighter.

[@gregeconomeier1476]

Not.

[@TheJoeSwanon]

Considering the extreme demand for that vehicle i’ll be surprised if they don’t. They’ve already cut into 10% of Tesla‘s sales average time on a dealer slot is 5 to 6 days!

[@logan594]

Heat pumps are actually most efficient in mild climate. In fact in negative temperatures, resistance heating can be more efficient.

[@DirtyFilthyPeasant]

This is what confused me, atleast with residential heat pumps they are less efficient in cold climates and sometimes need an auxiliary heat source.

[@maraudermanmarauderman7161]

Correct the typical home heat pump starts loosing efficiency at about 40 degrees and stops working at about 25 degrees. So a home system will switch to the back up heat source somewhere in that range. Not sure about the temps that R1234yf will work at though.

[@BigEightiesNewWave]

So if you needed a car that works and can be filled in 5 minutes or less and had to go somewhere ASAP you would hop into a good old ICE vehicle.

[@billyhouse1943]

@@BigEightiesNewWave this was year ago. I haven’t brought gas for a year. I still have not charged at a DC charger. I’m 78yo and my 73 yo girl friend likes the Mach-e but she gets range anxiety.

The heat pump is also, at least, 3 times more efficient in terms of electrical consumption to generate heat.

[@TheJoeSwanon]

Partially true from what I understand it decreases insufficiency as the temperature gets colder, At a certain point traditional resistive heating is needed.

[@pasad335]

That's because it does not "generate" heat, it moves it from once place to another. That's why it's called a heat "pump".

[@marcelomacedo4673]

@@TheJoeSwanon Thats correct, if outside temperature is too low the heat pumb will not work.

[@paulaxford6754]

But in many climates the heat pump excels. My Kona has one and the PTC has never switched on.

[@rkan2]

The heat pump not being able to extract heat at lower temperatures is only because of the working fuels like r1234yf - which do not do so well at those lower temperatures. You could use different types of fluids to work at lower temperatures - but those fluids range wouldn't work well for higher temperatures anymore.

[@RegnerBA]

Agree with the others! No need to apologies. It's great to see others and everyone over there seems to be super knowledgeable, so the content is great no matter what. Also, well done with improving the videos over time. The editing, audio, and just overall quality of the videos has improved and it shows.

[@My_HandleIs_]

Great description and explanation. What would put it over the top, would be an illustration of the cycle with an initial walk-through, and references to it along the way. I could follow this, as I'm aware of how the tech works, but for anyone new to the subject, it would be even more helpful. I loved the layout of the parts on the table, that in itself WAS kind of an illustration, albeit you had to really pay attention to not get lost. Thanks for all the nice videos Munro and Associates are producing, I think I have watched (and hit LIKE!) every single one!
