Ever since I rode in a BYD in China I've thought it would be great to be able to get one in the USA. It just really felt complete, put together and polished in a way that I haven't seen in a "normie" U.S. car in a long time. Too bad our country uses high tariffs and regulatory barriers to protect its dinosaur companies.
By dinosaur companies, you mean Tesla and Elon Musk
dinosaur would be a compliment for tesla which designs/releases one new car every decade (each delayed by a decade from initial release date) :)

At this point, a byd is a far superior car for the price. You should test drive one when you get a chance to escape North Korea, er, I mean America.

Ever since I ride them constantly in Chilean Ubers I wish other EVs were more prevalent because how the aluminum bends and creaks sometimes when I sit on the backseat doesn’t make me feel any safe (I weight 90kg).

Which is even more embarrassing, because they're miles ahead of the carmakers that came before them.
3000 hp? Not sure if that's measured at the "crank" or the dynamo, but that's over 2MW, probably pushing 2.5MW of power draw from the batteries assuming a motor efficiency of 90% and some other losses. Apparently that's getting drawn at 1.2kV from the batteries, so "only" around 2kA of current draw. That top power draw would drain the 80kWh batteries in around 2 minutes, though I'm guessing you'd hit thermal throttli…
> how the heat dissipation of EVs compares to ICE vehicles Xiaomi Su7 Ultra had a 400W twin fan, 530W liquid pump and a 28kW heat dissipation for powertrain.
28kW of dissipation is pretty solid, though obviously is irrelevant during a short burst with hundreds of watts of heat generated. I guess the frame itself act as the fallback heatsink for storing excess heat in these scenarios? Because by my math, a modest 100kg heatsink (no idea if that's reasonable) would reach 270°C in only around 45 secondw if it's trying to handle 250kW+ of heat transfer (270C is roughly the max differential for heat pipes,liquid cooling might be significantly lower limit). And obviously the batteries can't handle 270C.
Funny that it packs 3000hp while the Chiron « only » needs 1600hp to achieve mostly the same speed.
There was quite an interesting youtube from Engineering Explained speculating it had enough power to do 400 mph. There may have been other constraints limiting things like the tyres being safe and apparently the battery only has capacity for 2 mins at full power, plus bits may overheat and the like. ( https://youtu.be/z6q7du1q2U8 ) It's also interesting that the fastest time on the Nürburgring at 5 min 19 was from a…
>the battery only has capacity for 2 mins at full power
"The tires on the Veyron can only last 15 minutes at top speed, but that's ok because the fuel tank only has capacity for 7 minutes at top speed." (From memory, IIRC, Top Gear on the Veyron)
It's wild that after a hundred years there is still exponential progress in the power output of cars. The most unusual part to me is how EVs are fundamentally a consumer technology, so it all rapidly falls into mass production territory; eg. Xiaomi sells a 1527hp car for $73k. Horsepower is rapidly reaching 'solved' territory; even at its record speed, BYD's car wasn't even power limited.
Power for power’s sake is not necessarily a good thing. There is some indication that putting rapidly accelerating cars on streets is leading to a proliferation of accidents.
A car with a 4 second 0-60 time can reach 40mph, a speed lethal to 80% of pedestrians, in under 80 feet from a standstill. That's the distance from the limit line to the far crosswalk when crossing a 5 lane road.
Putting this level of performance (and better) into boring suburban SUVs bought by ambivalent consumers is negligence.

Haha what was the manufacturer? I drove a Changan Uni-T there and it was not an EV and handled like a boat but a very serviceable car. To be honest, I was surprised because it was the first Chinese car I'd driven and my mind was blown how far they'd come.
