Lease vs. Purchase The decision turns on many factors, both those set by the dealer and those set by your own personal wants & needs. For me, realizing the age of the ICE was soon to end, I leased a 6 speed manual BMW just about a year ago. It took a nationwide search to even find a manual...

To get to the bottom of this I called Tesla technical support (Matt). According to Matt, all Tesla models sold in the U.S. (S, X and 3) use R-134a. This is because Tesla is waiting for R-1234yf to be more "stable." We then chatted and, in our discussion, we posited that the EPA listing for S...

CO2 would certainly be nice versus R-1234yf vis-a-vis GWP, but it certainly could mean more service calls, something Tesla surely would want to avoid. The high pressure required (10x the norm) would mean that hoses, seals and other components would need substantiallly greater strength to...

I've read many analyses to the contrary. E.g. Honeywell defends R1234yf refrigerant against Daimler ("safety analysts estimate the risk of exposure to HF or fire due to an R1234yf ignition event at 100,000 times less likely than a vehicle collision due to brake failure"). There are many more...

Yes, thank you nwdiver. My comment did not tie refrigerants to cars specifically. But cars are a subset, and why would Tesla's subset use a refrigerant about to be banned by the EPA (and largely banned in the EU). Here is the EPA citation: The EPA has banned it for all new cars as of 2021 model...

I test drove an S yesterday at a Tesla event. I don't recall the production year, but after the test drive I had them open the front hood. On the passenger side, under the hood, is a refrigerant label stating that HFC-134a is used. Why would Tesla do that? HFC-134a, aka R-134a, has a GWP...
