No they aren’t. Quoted efficiency and observed efficiency do not line up in independent tests. Also build quality isn’t the same as efficiency anyways. Teslas rank at the absolute bottom of problems per car of not just EVs but ICE cars as well.
idk about your claim about chinas build quality being any better than American made Teslas since Tesla has already ran afoul of the govt as is. I don’t see anything factual to back up that claim. Just the China investigation and nhtsa investigation.
Well there's videos of the Chinese models as in what you quoted and most comparisons seem to point to Fremont being the biggest issue with build quality. They really aught to pause that factory for a few weeks and just take care of that once and for all, but with their growth targets they probably won't have any breathing room to do that until Texas is ramped.
The Tesla Model 3 was rated second best in a J.D. Power quality survey from the Chinese market—a much better result than vehicles from Tesla's California plant.

There's a few tests that disputed the EPA numbers, and you can look at different things, but they do generally lead the pack in efficiency, sure you could find areas a Taycan may win out but the EPA cycle is mixed load. And far better efficiency than Chinese cars like Nio right now.
There's little disputing they're the EV leader right now, and build quality aside there's obviously things China would want to learn from.
