For those of us who, after wracking our brains and wondering and thinking about how we could afford a Model S or X and realize we would be financially wise to wait, it's never too soon to speculate what the GenIII models (sedan, and presumably, a CUV) should be called.
It cannot be the Model T because that is still protected as a "live" registered trademark owned by Ford Motor Company.
My start would be Model TS and Model TX. Not overly imaginative, but makes the point and might be just different enough to avoid legal trouble with Ford.
Actually, they might decide to keep the "Model __" system for the higher-end GenII product line, and actually go with regular names. That didn't occur to me until just now.
Enough of my rambling - what do you think?
