How well does a BYD compare to a Tesla in an actual qualitative analysis, though? Just because a Chinese company sells more cars in China than Tesla doesn’t mean they’re better. Loongson has actually sold hundreds of thousands of their garbage chips in China too. It doesn’t make them better than an AMD. Also the US got to space on 1950s technology and designed the current ISS with 1980s technology. I think you’re overestimating the technology required to get to space. It requires monetary resources much more so than the newest tech.
Well, I can answer that, as I drove Tesla S and X and I own a BYD Dolphin from 2024.
Range-wise : there's a reason Tesla Model 3 Standard range use BYD batteries : a bit less range but far more durable.
Road worthiness : frankly, they're equivalent. BYD Dolphin for Europe has upgraded suspensions, and they're now all built to Europe's standards. They're no Dacia, Citroën nor Audi, but they're a notch above US cars with independent 4-wheel suspension. OK, LingLong tires suck, but those can easily be replaced.
Finishing : US-made Tesla are... underwhelming. Chinese-made ones have good building quality. BYD is Chinese, do the math.
Features : Tesla are more modern, with everything centered on the single huge screen. BYD have a small screen for driver comfort and a largish one for the rest - it can be switched off by voice, VERY nice at night. Tesla have more settings and games, BYD is far more spartan in comparison - still, enough to really fine-tune your car to your taste. Self-driving is limited to level 2, but it's actually usable on small, dirty countryside roads.
Final verdict : is BYD better than Tesla ? No. Is it better on price ? HELL YEAH !!! Performance per feature per dollar VS Tesla ? BYD does win.
