The success or failure of Model Y could make or break Tesla. If the vehicle appeals to buyers who hadn't previously been interested in a sedan like the Model 3 but couldn't afford a Model X, then it's all gravy. Of course, that also depends on whether Tesla is able to decide officially where to build it and if it can build it without the quality issues it suffered with Model 3.

However, if Tesla isn't able to deliver on its promises or the vehicle ends up sharing much less in terms of parts content with Model 3, then it could go very badly, though based on aesthetics alone, that doesn't look to be an issue. Remember though, that when Model X was announced, it was supposed to share a bulk of its parts with Model S but ended up only sharing around 30 percent.
