I’ve been looking at emission stickers of any brand for a few hours on the web. I’m even seeing vehicle sticker examples within the US EPA Federal documents that show that “California” is currently acknowledged and may be listed in the motor vehicles manufacturer statements.
Meaning even 2022 stickers currently state if a car is Certified to be possibly sold new in California. My 2022 F150 has listed that it is California Compliant to (ULEV70 LDT). That must be a Released CARB Document.
My understanding now is that most or all vehicles “Cars & Light Trucks” either entering the US or cars made in the States have compliance with CARB and have California present on the Emission Placard. I think it would be foolish for a vehicle manufacturer to produce a 49 State vehicle today.
GarageJDM brings up a very good point above, Porsche had a California destination version list on the options on the Option Sticker under the hood “Frunk” as the California Version. (Option Code 027).
The takeaway from this discussion is that there were 49 state vehicles made by Porsche in 1983, possibly 1980-1983. To be sold new in California it would need to have Option 027.
