I would be disappointed if Tesla's next sports car is an expensive "supercar" that only the very well off could afford, and by that I mean a starting price of something over $100K. Tesla already did that with the Roadster.
I hope the next Tesla sports car starts at $40-45K and offers a 200 mile range, only 2 seats, decent trunk space, 0-60 in under 6 seconds, and great handling with coils. Manual seats. No fancy falcon wing doors or other gimmicks. That would be a really fun car that would sell like crazy. With the gigafactory and Gen III technology that should be doable and the car would be profitable. It would a be better car than a base Porsche Boxster or Cayman for much less money.
Then options could be offered to greatly increase the range, suspension capability, various goodies (high end sound, power seats, LED headlights, active aerodynamics, air suspension, etc.) and much higher motor power to get the 0-60 down to under 3.5 seconds. That could take the cost up to $100K.
In that way Tesla would have a sports car with broad appeal, with the base version making a great commuter car and a solid sports car, and the maxed out version wold be superior to the Porsche 911 and competitors.
