> What prevents car manufacturers from taking a normal-looking body style and electrifying it?

Audi and BMW have been doing this for years at this point.

BMW i4 is a 4 series grand coupe (i.e., hatchback sedan in this case).

Audi ev suvs are super close to the gas versions. Both are shifting overlapped designs around though, perhaps specializing.

Also, it seems Mercedes will discontinue the EQS and EQE lines and replace them with electric S- and E-Class: https://www.autocar.co.uk/car-news/new-cars/electric-mercede...
