I have a feeling that if you had 4 cars
1. Heat pump. Non ev tire.
2. Heat pump. Low rolling resistance Ev tire
3. No Heat pump. Non ev tire.
4. No Heat pump. Low rolling resistance Ev tire
And Ran these over the same course at the same time. Weights Added for driver made that the difference in consumption would be within the 1% accuracy we have from the charger.
If this is not the case why are their not tests done with actual data showing the effects?
If I were selling an ev and had an optional heat pump and it made a noticeable difference I would publish that data. **** I would publish it if it made a small difference. I do not understand the silence / secrecy and lack of data from car companies.
Then again after vw do we believe them by default anyway?
You know what would be interesting. A Volvo rally from point a to point b (and back) with trip counters reset and pictures of the before and after charge rates and trip efficiencies recorded.
Evs with various configurations. Some people liking to be hot others ac on full blast. Some really living life and playing music.
A modified version of this which would be less accurate but would give some data is the above trip. Same recorded data but you do it when ever you want and just publish the data on a thread. We could add in a time collection and see the difference velocity makes. (Would need temperature as well).
perhaps after this heat wave I will publish a thread on doing this. I would say during heat wave would be great data but I do not want melted road crud on my car
