When my Prius's hybrid battery died, I swapped out the two bad cells (out of 28) for good ones. Cost of parts and labour: $300.
Did you do it at a dealership, at a non-affiliated garage, or yourself? I could see how there could be situations when someone tries to sell you into changing all the cells, even when that’s not necessary.

How long did that last? I have a Prius that's at 100k right now. Repairing the battery is within my abilities but I'm concerned that if one or two cells fail, more will be right behind it.

Not the OP. At the end of the day it’s just taste, right? I use Linux, EMacs with vim keybindings and a dark color palette. Coding this way makes me feel good, I like the aesthetics. If they tried to force me to use Windows, and an IDE with a light color palette, I’d seriously consider quitting. It’s totally irrational, but it is what it is :D
Definitely a matter of taste- your dev environment sounds downright VILE to me ;-)

Transmission ratio yes, as in, what part of engine power gets transmitted to the wheels. Individual gear ratios of course not.
So the relationship between engine RPM and wheel RPM is always fixed, only torque split is varied, right? I think that's around where some confusions are coming from.
This page has a neat PSD simulation to help grok what happens:
I think it only works from a computer though!

What’s wrong with BMW’s platform? The technology (e.g. heat pump, carbon fiber/aluminum body), user interface and fuel economy (not range) of my old i3 are all competitive with the 2022-2024 EVs I’ve driven. Unless they somehow regressed 10 years, the only obvious problem with the new BMW EVs is that none offer a third row.
i3 is fugly as hell and not many bought it.
The i8 was also a special snowflake (hybrid supercar with wing doors and questionable transmission), but what about the i4, i7 and iX?
They all look extremely competitive.

The problems with the Prius are basically: - Terrible in snow and ice - No way to defrost your windshield, unless you're already driving - Poor rear window visibility If not for those things it would be great, but unfortunately they've made zero progress on fixing any of the core issues for the last 25 years. The new models definitely do look cooler, and I appreciate that they accelerate faster, but I personally care…
I own a Prius and live in Vermont. It does just fine with snow and ice. As others have pointed out, proper snow tires make a huge difference, way more than any car tech. I also think the newer models have AWD as an option. To defrost, you can just turn the car on, switch out of EV mode, and turn on the defroster. It works like every other car. The rear window visibility is not the best. I do agree there.

Also, have they sorted out the 12V battery management for this low use scenario? Our family has an older Hybrid Camry from around 2010 and it will destroy 12V batteries with too much local driving and parking. A typical regular ICE does better in the same conditions. From the behavior, I assume it's because they only charged the 12V via a weak alternator when the ICE runs, rather than also keeping it charged via DC-D…
They haven't solved it. I just returned from a 21 day trip and my 12v was dead because I left the Prius off the charger. It's fine as long as it's on the charger (my guess is it trickle charges it), but if you leave it off the charger, the traction battery doesn't maintain the 12v.
We resorted to installing a big master cutoff switch on the negative battery terminal in the trunk of the Camry. So if there is no plan to use the car again in the next few days, we electrically isolate the battery.
Then, we have to go through a longer "boot up" process to reactivate the car for its next use. Use the mechanical key to open the trunk, restore power, then enter the cabin and go through multiple cycles with the START button to let all the computers power back up...
Toyota explicitly stated that the hybrid strategy spreads the lithium out to more cars, increasing fuel economy across the fleet. Tesla's 800hp super cars aren't green and never were. They consume lithium to such a degree that they are, maybe even worse in the long run. Using 800 horses to transport one human never could be efficient, no matter the technology.
The lithium isn’t consumed.

New prime 2024 has no awd.

No. Chains are better. My Land Cruiser has a timing belt. I replace it every 90k miles per Toyota's specifications. My Tundra has the same engine, except that it has a timing chain. I've never bothered to replace the timing chain. A timing chain is preferable as long as it isn't something like a Jaguar/Land Rover. The chain in those doesn't matter because they use plastic tensioners that eventually become brittle at…
Chains can stretch, weigh more and make noise. This is why belts are used, in addition to being a space saver. The ultimate in reliability are gear drives. Those truly never wear out or need replaced (found in nearly any diesel engine). Chains were very common in American cars and trucks for decades and they did need replaced after 150k-200k miles. I replaced the one in my 1993 Ford 5.0 at about 150k hard miles and i…
