I dont have so serious space limitations but a few more bateries on the whishbones place won´t do any harm
I can however have double whishbone suspension but also mountings for the eCorner system. I´ll drive with double susp. untill the eCorner comes out then change it and fill the space with batteries
About the hydraulics speed - I assume they do because Mercedes used hydraulics for tilting the wheels in the Carver
