I don't think a <$25K base price Tesla is feasible at this time unless they strip it down of all technology besides the EV portion (ala Nissan Leaf which basically is similar to a Versa) , make the car & wheelbase even smaller (compact / C-segment/ Toyota Prius/Ford Focus /Honda Civic /Mazda 3 / Subaru Impreza sub 185" length , OR sub-compact / B segment / Ford Fiesta / Ford C-max /Honda Fit/scion ia size , sub 180" length), and acquire the battery far cheaper. If they do make it a car that is shorter than 180" , to keep practicality it would likely have to be a hatchback (Ford Fiesta/Ford C-max/Honda Fit ). Once you take away the luxury/performance and features, you're competing vs Nissan Leaf , Ford Focus Energi / C-Max energi, Fiat 500e (California). It's also much harder to get a 5 star crash rating when there is less space for the crumple zones , so I doubt they will go subcompact.
