3. The Origin of the Name
If you are wondering why Elon Musk has named this model Y, here is your answer. Musk wanted to call his first three models the S, E, and X. The reason is what they spelled out. However, as Model E was already owned, he had to call his smaller sedan the Model 3. Then, he added this latest model and named it Model Y, so his cars spell out S3XY.
