California DMV seems to have recently added "2012 Tesla Model S3" (sic) to their list of cars eligible for Clean Air (HOV) Sticker program. This is in addition to "2012 Model S" that is already approved. Any guesses what this means? - typo? - reference to "Gen III"? (seems odd for it to be approved as a 2012) - a code for the Model X? - a new code for the remaining 2012 Roadsters? (seems odd as the 2011 list shows the right name "Tesla Roadster" as approved), - maybe a designation for the Performance version of the Model S (unlikely as Roadsters and Roadster Sport both were just shown by DMV as "Roadster" despite motor/output differences) - something else entering testing, like another variant of Model S (4wd maybe)? source is here: Eligible Vehicles - Single Occupant Carpool Lane Use Stickers I know I checked that list a few weeks ago and there was no "S3", just Model S... so I'm pretty sure this is a recent addition.
