Isn't it a S3X(-y) Semi-Family?
Tesla just released a photo with four of its electric vehicles - three production cars (Model 3, Model S and Model X) and the upcoming Semi truck.
Well, the family is missing grandpa Roadster, and the new Roadster - although the new Roadster likes to hide in the trucks (remember the unveiling event?) so maybe it's on the scene... we just don't see it.
In case you'd like the image as wallpaper, here is a 2,560 x 1,440 version:
