Maybe. The upgraded plumbing system on 2023.5 that allows motor heat recovery was a much bigger deal efficiency-wise. Heat pump will be a smaller gain, but more expensive.
Lee, what is the definition of 2023.5 … how can I tell whether mine is 23 or 23.5?

thanks

07/2023 or later on the door jamb sticker.
thank you.

mine is 07/2023 so presumably it has the upgraded plumbing system. That’s nice to know.

is the effect of the plumbing upgrade that cold weather cabin heating is improved with less HVB drain?

Someone please correct me if I'm wrong, but I believe motor heat was previously "thrown away" to atmosphere, but is now reclaimed for battery and/or cabin?

I don't remember where I saw it, but the advantage can be as low as 4% over using resistence heating.

@Mach-Lee

Lee, I found your comprehensive post on this issue from March 10. Well done, thank you.

Also noted that someone in that thread indicated other indicators of 2023.5 were the mobile charger was no longer a freebe and BC trial down from 3 years to 90 days. On my car the mobile charger was a $500 option and BC is 90 days. So I'm presuming mine is a 2023.5 but at the end of the day, it is what it is. Nothing I can do or not do about it at this point.

Thanks again for your prior, thorough write up on these issues and changes to the vehicles. Reminded me of reading a synopsis of an expert's opinion report. Prior to retirment I was an attorney who for the last 20 years of so of practice focused on defense of design professionals in the E&C industry. Although not an engineer, I spent more hours than I can possible count consulting with engineers on various matters. I really enjoyed the work, and trying to understand what they were trying to explain to me! Fascinating stuff, to me, and I think all the design professionals involved.

Heat pump isn’t always as good as it sounds. It’s only beneficial in some temperature ranges in some conditions. Otherwise the power difference is hardly worth the complexity and additional cost of a heat pump system.
My Mach E doesn’t use that much more power in the winter for heating than my model 3 with heat pump did.
