That's probably one of the least interesting records. Besides the tires, what's the problem reaching that speed? Need a big engine and some downforce. This is much easier than building a car that cam set a record on the track.

It seems to me like building the fastest EV has nowhere near the complexity of building the fastest ICE car. Way too many moving parts and fine tuning required to get an engine to 440Kmh (Chiron SS) than an EV with 4 big motors.
I find it interesting that Chinese brands copy Western brands, then Western brands copy Chinese brands and so on. Result is that new cohort of cars look like characterless AI slop.
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.
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 throttling or catastrophic failure before that. The batteries are allegedly rated to 30C, meaning 2 minutes to full discharge at max current.
I'm curious how the heat dissipation of EVs compares to ICE vehicles. You have much higher efficiency vs combustion and get to split the power between 4 motors instead of one engine, but you don't get the heat capacity of a massive engine block, or the convection of cold air intake + hot exhaust out the tailpipe.
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.

I’m fine with tariffs that keep around industries that are needed during wartime. That’s why there are tariffs on cars, no other reason is even remotely important. It has zero to do with GM and Ford making profits and everything to do with keeping GM and Ford around so they can pump out war materiel if needed.
yeah same thing when I tried their Huawei phones. their mobile phone market is much more innovative due to the competition it's a bit of a shame the monopolies stifle competitors to grasp their crown a little longer
