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.

It might indeed be more difficult to push obsolete technology ever further.

People have been putting engines that powerful in cars since Campbell's blue bird in the 1930s. I'm not going to say it's easy, but it's doable in custom vehicles.

The hard bits are connecting that power with the ground long enough to reach speed safely, and storing enough energy to do so. EVs don't solve that.

Is it a production car if they have made one and have sold zero?

The Yangwang U9 is a production car. This is a boosted version, the 9X Track Edition.

The regular 9X costs about US$236,000 before Trump tariffs. About half of a Ferrari. Also jumps potholes, can do tank turns, and has some autonomous capability.[1]

There's also the Yangwang U8, which is an hybrid off-road SUV. Does tank turns, and floats.

It's really a promotion for their other cars, but these things are sold in the UAE, Kuwait, and China, at least.

Isn't the complexity in storing and and moving the electrons rapidly? Stringing a bunch of 18650s with a copper wire harness won't cut it. You've got to invent some novel chemistries and new materials to pull it off.

Yet none of the other mainstream automakers has done so.

Are they even trying? It seems like the only reason to do this is for publicity. Maybe a manufacturer that's known for their ICE vehicles would want an opportunity to show off their electric vehicle engineering but I don't know any it would make a difference for. US manufacturers even sell electric trucks. It's not like any mainstream manufacturer needs to rebrand to sell electric vehicles.

I recommend you watch this video (the channel's pretty good in general):

While I agree with your statement in broad strokes - I'd reframe it as the same amount of engineering takes you much further in an EV than an ICE car. Considering this, the Chinese really swung for the fences, and what they made here is quite impressive

Chiron still has that Piëch handwriting on it. It's driveable enough to take your wife to the opera. Full regulatory compliance, low wind noise at high speeds, all that. I don't want to say it is compromised, but it's not as extreme as it could be.

The closer ICE comparison would be Koenigsegg (447 kph/278 mph), Hennessy Venom GT (435/270) and SSC Tuatara (455/283, no shenanigans). SSC have reached 295, they were clearly aiming for 300. It's no 308 but it's reasonably close.

All these are also relatively small companies with relatively low budgets -- none of the big manufacturers seem interested in top speeds anymore.

Which shows that ICEs are a ridiculous choice for performance cars?
