You just explained why they shouldn't make an EV in your own post:
* Companies struggle to make EVs that look normal. Look is a massive part of these companies.
* EV typically don't have the handling and driving response that expensive sports car buyers are looking for. Typically a lot heavier, tougher suspension to support it, meaning affected feel and response.
* Ultimately, it's not about speed. Ferrari and Porsche don't make the fastest cars on the planet. They make a driving experience attached to an identity. The driving experience of an EV is vastly different from existing ICE cars.
Sure, they can make them, but sales will be dismal for brands that are already low-volume sellers. I've seen little to no evidence that their actual customer bases are interested in buying these products. Like I said before, if you want the fastest EV around, Tesla already did that and has been doing it for years.
As for a 911, again, that's the driving experience attached to a small, highly-powered, relatively-light and nimble car. An EV will have a tough time replicating that with current technology. I'm not an anti-EV person at all -- I simply don't think they make sense for this particular segment of buyers. These people are not focused on practicality or being the Jetsons, as you said.
