Taycan sells because it’s a Porsche not because it’s a particularly compelling product. I know many colleagues who purchased them over other/better EVs simply because of the badge.I don't think an EV needs to take advantage of BEV proportioning to the best.
Style is luxury, and compromising packaging for the sake of style is a luxury. Look at the Taycan, incredibly successful yet not very well packaged for a 4-door sedan. But looks sexy, low-slung, and long. Style definitely can sell.
If every BEV takes on the same wedged cab-forward look, you can't really stand out like that imo. The Lexus LF-ZC concept looks good now but I think it's shape won't age well at all.
