Model Y will
very likely seat exactly 5 people (with much more cargo room compared to M3).
One functional reason X had FWD's was 3rd row access.
If there is no 3rd row, there will less reason to have FWD's.
Electrically actuated FWD for driver entrance is absolutely not acceptable in terms of rapidness.
Also there is not enough playroom to make lot's of expensive gadgets on a vehicle that costs 40k.
The biggest difference will be the rear part anyway (remember, MY will be based on M3).
Nose will be stubby like M3. Clearance will be larger, though less than MX.
Windscreen will be around the same as M3, panorama roof extending behind rear passenger heads
(like Model S plus at least 10cm, 4", aka MS design flaw fix) and much more practical trunk, likely
hatchback, but much steeper - with best aerodynamics vs cargo capacity possible.
I expect something like BMW 3-series GT, though longer passenger compartment/cargo area due to no engine.
And also higher than that to make it more like CUV.
So yea. Same nose, likely same front doors, more mom-friendly rear doors with more head entrance clearance, longer trunk (20cm?),
more likely to have roof rack possibility. Not likely to have sunroof option (only glass roof). Likely 18" and 19" wheels (bigger sidewalls possible). Similar color options (same paint line). Same driveunit(s). RWD and AWD offered forever (RWD will not be dropped).
Same battery pack dimensions and parameters (same as S vs X). Same onboard charger. Same HVAC, same dash.
This is the only way to keep Tesla's reliability above average - they can't make new stuff from ground up again and again.
(watch latest ConsumerReports videos about vehicle manufacturer reliability data).
So in around 2020, Tesla will offer these passenger vehicles (model Y ramp-up will be much faster compared to Model 3):
Roadster2, as a fun sports car for enthusiasts.
Model S, as an expensive premium large liftback
Model X, as an expensive premium SUV vehicle
Model 3, as a practical mid-class sporty sedan
Model Y, as a practical mid-class CUV hatchback
PS: BMW 3-series is categorized as entry-level luxury (compact executive) car.
Model 3 is not compact, being wider and longer. Nor is it luxury (somewhat opposite to sporty).
I expect Model Y will cost almost the same as Model 3. Close competitor should likely be something like BMW 3-series touring or GT.
I expect 1500-2000€ difference in starting price and not a long options list (towing capability might be the most notable feature difference). Performance M3 will outperform performance MY (same as S vs X).
Tesla will likely never make entry-level passenger vehicle (anything cheaper than Model 3 SR).
I would also not bet on a regular pickup truck. Other manufacturers should
pick up by then anyway (competition).
Practicality of a "passenger class pick-up truck", no matter how you twist it, makes little sense.
Tesla doesn't have to do every kind of vehicle on the market to accelerate sustainable transportation.
Most vehicle manufacturers limit their field. Let's keep Tesla sexy.
Also accelerating US specifically (Asia&Europe are absolutely not interested in pickups) has little effect. Also it is a wrong direction
to accelerate after all. Cargo haulers, busses, worldwide charging infrastructure. Much more important on this planet.
Huh, that should be enough.
