I think many potential customers would be delighted to see the Model Y come with center opening (suicice) doors. Would offer unique styling and offer excellent rear seat access.
Towing capacity of 3,000 lbs would allow towing of small trailers as well as hitch mounted bike racks and cargo trunks.
Multiple battery capacity could allow a wide range of pricing.
Optional auto pilot configurations would please many.
The Hatch back will offer many conveniences.
Smaller cross over SUV's are currently the Hot Spot in the marketplace. The fastest growing segment. They appeal to all age groups and family sizes.
Probably, like others the highest priced/optioned versions will be offered first. There will be many in line to get the first couple years of production and it should keep Tesla on a rapid growth curve.
The profits from the higher priced versions will go towards paying off the massive developmental costs of both the vehicle and the plant. Since Tesla has gained knowledge from production of previous vehicles, it makes sense that they will become more efficient in doing so.
I predict the Model Y will become super popular with dog owners, out doors types, sports oriented people, retirees, singles, newleyweds, Minivan haters, smaller families, small business owners, campers, road trippers, commuters, and first time EV buyers.
With world wide demand, the Model Y will most likely become the highest production volume vehicle in the growing Tesla lineup.
