> Tesla's tend to be even higher because of the larger batteries and less efficient production This is false and actually the opposite is true. They actually used Model S sedan figures (3mi/kWh) for efficiency to compare to Camry sized vehicle. The more appropriate comparison is to a Model 3, which gets 4mi/kWh. People underestimate how efficient Tesla’s powertrains are compared to most competitors. Tesla tends to do much BETTER at efficiency than their peers, not worse.

I assumed Teslas had poor fuel efficiency due to their size, but then I found this: https://evtool.ucsusa.org https://evtool.ucsusa.org The Model 3's (mid range 2020) MPGe-CO2 is a bit better than a BMW i3 (2018). The i3 is a little euro city car thing. They carefully optimized the BMW for weight, and also have some funky custom ultra efficient tires. For example, the frame is made of (hemp - supposedly lighter) fiberglass and carbon fiber, and they didn't offer power seats. It has a tiny trunk / no front trunk. It only gets EPA 135 miles per charge. The BMW and Tesla are both much better than a 2022 BMW i4, Nissan Leaf, or Polestar 2. They're a bit better than the most recent Fiat 500e, which is closer to the i3's size. Tesla's energy efficiency vs. size is really impressive.

I'm not talking about efficiency per mile. I'm talking about manufacturing efficiency. Tesla pulls stunts like building a giga factory in AZ for the tax breaks. It makes economic sense but does not make sense when measuring by the added emissions necessary to concentrate all those materials so far away from the rest of the supply chain loop They're also just... bad at making them. A 2020 survey by JD Power found that Tesla ranked last of the 38 brands they looked at in initial quality. It's a measurement of how many problems new vehicles face in the first 90 days of owning them This is consistent with Consumer Reports rankings of Tesla as second to last in reliability This is what I'm talking about when I say "inefficient manufacturing".
