The $25k car is going extinct?

The more interesting question is why these cars disappeared in the US. And while many of the factors discussed here are true for both EU and US (inflation, interest rates, manufacturer profit margins etc) I am surprised no one mentioned the 'SUV loophole' of US regulations that effectively boosted the SUVs (off-road vehicles are classified as non-passenger automobiles with everything that entails, notably much less stringent emission standards) and made the small cars unprofitable to make in comparison.

This has become the irrelevant part because "does it have an electric motor in the powertrain" has become more important to fuel economy than vehicle size. There are hybrid SUVs that get better MPG than non-hybrid sedans, to say nothing of the full electric ones.

Which is another reason the average price is increasing. Hybrids have a lower TCO even though they have a higher initial purchase price. People who can do the math realize that paying more up front for a hybrid or full electric is paying less long-term. But then the market for lower priced new cars declines, because the people who can afford a new car can afford to pay a little extra for long-term savings and most of the people who can't afford to do that were buying used to begin with.

Is this conclusion based just on fuel consumption? From a relatability standpoint, it doesn’t make sense at first blush because you have to have both ICE and EV parts in series in the drivetrain; the total reliability can’t be higher than the individual components of they’re in series.

And then you're also keeping the moving parts more in their happy zone of temperature, speed, and load instead of needing them to operate in as wide of conditions.

A hybrid, by definition, combines an ICE and electric drivetrain. While I understand it could be designed for a more efficient range of operation* how could it negate the downsides of an ICE-only design if it requires an ICE? (Are we conflating EV and hybrid?)

* This also means each segment is less globally efficient, meaning the system is less efficient if it has to limp along if one part is inoperable

The pure ICE engine and transmission has to deal with some of the most stressful times the motor can handle, extremely high torque demands coming from a stop. Its far less stressful for an electric motor to generate good torque at such low RPMs.

Just two quick examples.

A key part of my original statement.

A series hybrid or parallel series hybrid will often have a far simpler transmission in terms of moving parts and what not. You're right, they'll use the gas motor for power going highway speeds, but they're still a lot simpler. Many hybrids effectively only have a single speed for the ICE motor in their "transmission", some have 2-4, compared to modern ICE transmissions which are like 7+ gears.

Note, I do agree, there are some hybrid drive trains that are more complicated than their ICE counterparts, but it is not a given. Many hybrids are a good bit simpler in the end.

One example of a simpler setup would be Toyota's Hybrid Synergy Drive. e-CVT's can be radically simpler mechanically.

The math is clear: in series, the system reliability cannot be greater than any single part.

So if the claim is that hybrids are more reliable than ICE, there needs to be some sort of discussion about why you think the ICE is more reliable. You keep bringing up transmissions when the main point is related to the ICE.
