The automaker's JB Straubel says that the Model 3 will include not just the expected sedans, but crossovers as well. There aren't more details at this point, but it's apparent that the new EV series is about transforming Tesla into a more accessible brand, not just giving you a lower-cost alternative to a Model S.
Straubel is certainly optimistic about what the 3 range can do. He expects to see a million Teslas on the road by 2020, which would make Elon Musk's outfit considerably more than a niche badge.
