I think anything can be made cheaper with sufficient volume. But who wants sports car performance? Not too many people. The EV crowd are apparently satisfied with "Ludicrous mode" for now. The sports car crowd specifically want overall performance and a particular kind of feel from the car. Will cost a lot more to develop an EV with competitive attributes to most sports cars. It will happen, but not for another 5-10 years when battery weight is reduced significantly and thermal mgmt tech is able to properly cool the pack.
I disagree. I think that just about everyone wants to have a sports car. That is, everyone who actually enjoys driving anyway. Those people who only believe that vehicles are necessary appliances to go from one place to another need not apply.
The practicality of life is what prevents people from buying sports cars. The financial concern when one can only afford to own one car at a time... So that car has to be all things for all the purposes they expect to encounter during the ownership process... The fiscal need to own something that doesn't eat gasoline like no tomorrow means that someone who has become used to the mileage of a Civic or Corolla would be appalled by even the fuel economy of a 3-Series, let alone a Corvette or Camaro. Some people need to haul people, and stuff, rather often... So they cannot justify a two-seater convertible with a shoebox for a trunk.
That said, I doubt seriously that there are people that grew up with a poster of a silver/grey Dodge Caravan or Toyota Sienna on their bedroom wall. More likely they looked forward to
'some day' driving something with flowing lines and fenders and a particular emblem... Lamborghini, Porsche, or Ferrari proudly displayed on its flaming red or bright yellow hindquarters.
When gasoline was cheap and plentiful, and a Mustang, Camaro, Firebird, or Challenger could be acquired for $3,000 to $5,000 each, those sold like gangbusters. If it were possible to have the functional equivalent of those vehicles for an effective $25,000 or less, without any of the downsides they offer, they would be incredibly popular today. The Toyota Camry, Honda Accord, Honda Civic, and Toyota Corolla may not offer road burning performance, but they certainly set the standard for baseline minimum that consumers are willing to accept for the price. Which is interesting, because their current prices are right in line with what a Camaro, Firebird, or Mustang would have cost 25 years ago.
People want sports cars. They have simply been conditioned to believe they shouldn't or couldn't have one. Electric cars can turn the tables and set a new standard as a baseline minimum. It would be unwise to not take that advantage while it presents itself.
