A question about Toyota VIN numbers (US vs. world; HEV vs. PHEV)

For this particular question, I'm really only looking for replies from people who know the answer for absolute fact. If you're making an educated guess, please make sure to say so.


So I was doing a little digging on the parts database portion of Toyota's Europe tech website and noticed something a little interesting, but I don't know how to fully interpret it. When looking at engine wiring harnesses, I noticed that there was a set of revisions that started in Jan 2025; likely at the break between the 2024 and 2025 model years. I'm sure the harnesses are functionally equivalent, and any differences between them are not the point here. The point is that you get specific serial numbers for the switch, broken down by model if you hover the cursor over the production start info.

The numbers given are:
MXWH60 - 3048953 (FWD HEV)
MXWH61 - 3040206 (FWD PHEV)
MXWH65 - 3024982 (AWD HEV)


My first question is about region. Does each country/region get its own sequence or is it done globally?
For instance...
Scenario #1: US car 3000001(US), next car off the line goes to Europe and is 3000001(EU), the next to US is 3000002(US)
Scenario #2: US car 3000001, next car off the line goes to Europe and is 3000002, the next to US is 3000003


The second question is about HEV vs. PHEV and FWD vs. AWD. The highest number of the three is 48,953. Can we view that as the superset of all three models, or is it just the FWD HEV subset?
For instance...
Scenario #1: Total '23 & '24 Prius production = 60+61+65 = 48,953
Scenario #2: Total* '23 & '24 Prius production = 48,953(60) + 40,206(61) + 24,982(65) = 114,141

*In this scenario, the total number would likely only include Prius models with the 2.0L M20A engine. Japanese Priuses with the older 1.8L and all Mexican Priuses would not be included. Those cars are ZVW60.



If we combine the scenarios into the two most likely configurations, then either 48,905 Priuses were produced for the US market over the first two years of gen5 production, or 114,141 Priuses with the 2.0L engine were produced for all markets for those first two years. I'm just curious which of the two possibilities is the correct one. (BTW, they can't both be true.)

 

Thanks. Yeah, that triple example pretty much locks it down. So it's probably safe to say that Toyota made something in the neighborhood of 130k-140k total Priuses over the two-year span. (114k worldwide with the 2.0 and something like 15k-25k with the 1.8 for Japan and Mexico - very, very rough guess on the 1.8).
