@Eunos_Cosmo and
@Keef, have either of you seen the new Lotus BEV sports car chassis architecture?
It's very similar to a mid-engine layout, with the battery packs mounted behind the driver and passenger. It can accommodate up to 100 KWH worth of battery pack, and either a single or twin motor set-up behind it (in line with the rear axles). Plus the wheelbase is around 400mm shorter than a Tesla model 3's (which i guess is the typical BEV go-to metric, when it comes to efficient packaging standards).
Hopefully Porsche will take a similar route with their Cayman replacement BEV, as it looks like a good recipe for an all electric sports car, with mid-engine handling characteristics (in my opinion).
