Well for starters between the two of them they sell 1 vehicle (the Prius) that meets the regulation. Ford sells 2.
But really thats not it. The Law only impacts manufacturers that sell 60K plus cars per year in Calif. Sell less than 4K lifetime exemption, between 4K and 60k you get years until you have to meet the requirement.
So the following brands have at least 4 yrs of unrestricted sales (Audi, Bentley, Bugatti, Hyundai, Kia, Lamborghini, Mazda, Volkswagen, plus any new makers – China, India) Brands in the permanent exception range. (Aston Marting, Ferrari, Isuzu, Jaguar, Land Rover, Lotus, Maserati, Mitsubishi, Subaru, Suzuki, Porsche, Tesla.)
Now depending on how they run the numbers (I am not sure how long a selling history they look at) but If its yearly, You could see lots of yo-yoing as a manufacturer has an exemption so they can sell there cars for several thousand less, than they exceed the number so for a year or two sell few, then bounce back.
Now if your a Manufacturer with several brands, you potentially set them up to bounce in and out of the requirement at different times so you always have a brand that the rules don’t apply to. Of course Toyota, and Honda with fewer brands would not be as able to play this game.
But what does any of this have to do with saving the environment, why even have these exemptions?
I finally found out what stops you in California from driving to Nevada to buy your car. The bill prohibits any resident from bringing a new vehicle with fewer than 7,500 miles on it into the state.
So now there will be lots of never been on the road (maybe never had the engine on) new cars rolling off Dyno’s in Nevada with 7,500.01 miles on them.
