Honda and Toyota both slow played full electrification, emphasizing non-plug-in vehicles even as plug in models started moving real volumes.

But Toyota was at least putting a real push in increasing their hybrid lineup, and lining up increasing amounts of electric drivetrains (batteries, motors, regenerative braking chargers, etc.) in their supply chain.

In 2025, Honda sold 1.4 million vehicles in North America, 430,000 of which were electrified vehicles (50,000 of those being the GM-manufactured Prologue and ZDX), mostly non-plug-in hybrids. Honda has refused to bring a plug-in hybrid to market. Looking at the actual manufacturing, Honda has only partially electrified something like 25% of their vehicles.

Meanwhile, Toyota moved 2.5 million vehicles, 47% of which were electrified. About 50,000 of them were plug-in hybrids and 22,000 were full electric. That's not a lot, but at least they developed their own EVs, have a supply chain for literally millions of (small) batteries and regenerative chargers and electric motors in finished cars.

When it comes time to really put out EVs, Toyota is in a much better position to survive the transition than Honda is.

Today's new cars are tomorrow's used cars. What happens in the new car market now will directly affect what is available on the used car market 5, 10, 15 years from now.

Gasoline needs a precise air/fuel ratio to ignite

Yes, and it forms fumes in those ratios as soon as it spills. A puddle of gasoline is flammable. And once it ignites, it creates a runaway condition where the heat output of the reaction ignites the fuel around it, too.

If you have fast charging, why do you need a big battery?

Road trips. Being able to drive 4-5 hours between stops is better than being able to drive 2-3 hours, even if you don't have to stop for all that long. Small fuel tanks are annoying in gasoline powered vehicles, even if a fill up can be less than 3 minutes.

Isn't that also true of literal gasoline?

A 15-gallon tank of gasoline has about 1800 megajoules or 500 kWh stored, ready to combust when mixed with oxygen and heat.

You crash test the actual modules and make sure it doesn't short when encountering highway crash forces, same as you do for gasoline tanks.

1100kW means 18.3 kWh/minute, which for a 3 mi/kWh car is 55 miles (almost 90km) added to a car's range in just one minute of charging. For a 4 mi/kWh car, that's about 73 miles (almost 120 km) in a minute. That's wild.

A gasoline pump delivers about 10 gallons per minute, so for a 25 mpg car, a gasoline pump gets about 250 miles (400 km) per minute, so there's still a gap. But the gap is shrinking.

For everything the Trump administration has done to make solar and wind power less economically feasible, it turns out his war in Iran has done way more to make fossil fuel consumption less economically feasible as well.

There really was a huge increase in the number of EV models available between model years 2018 and 2023.

So now, when you're looking to buy a 3-year-old car, you have so many more EV options to choose from even compared to just 2 years ago.

You can choose different form factors (small cars, sedans, wagon/crossover/small SUVs, medium SUVs, literal pickup trucks), and basically any price tier from economy to ultra luxury high end.

Not every ecological niche was filled in the past 5 years, and some still need a bit more competition, but even with some pullback over the last year there are still plenty of new EVs hitting new categories (e.g., true three-row SUVs and minivans) that will feed into tomorrow's used market.

And not every model will survive. The future of all-electric full size pickups looks pretty grim. Some entire companies might not survive the EV transition (looking at you, Honda). But overall, the used market will fill out with what was hitting the new market 5-10 years ago, and we'll start to see a lot of consumer preferences start showing what the future of cars will look like.

The spec say 1.8x3-3.5m

Are you talking about the entire width and length of the vehicle? The roof is smaller than the total footprint. Especially because the width of the vehicle includes the mirrors sticking out.

10% seems rather low.

No, it's pretty high for the use case you describe. Utility scale solar with panels pointed toward the sun tends to achieve about 20-25%, with some American desert installations at 30%.

Home balcony solar tends to get 10% in places like Germany, with the higher latitude and higher likelihood of overcast skies.

Putting it on a vehicle roof would be lower than that.

So 2 kwh per day is optimistic.

i don't really need more than 30km a week.

So why buy a vehicle at all? Seems like the resources that go into an underutilized vehicle would be better used for things like paying fares on taxis.

You're better off just charging with 100% utility solar/wind from the grid and paying money for it, rather than trying to combine a mediocre solar array in a costly way that kills your vehicle efficiency.

Plus there are probably some efficiency losses in an inverter taking the DC output of the solar-charged battery and generating an AC waveform expected by the car's ICCU, to be redirected into charging the cells of the actual car.

Yeah, that's why I used a capacity factor of 10%, which is pretty normal for fixed solar panels. That should be enough to account for clouds/weather, nighttime, etc.

The Slate truck doesn't exist yet, at least not as a street legal mass produced vehicle. They're aiming for a late 2026 launch, but they're not there yet.
