In case anyone was wondering, Porsche says you can only flat-tow a Taycan. Tesla recommends a flat-tow but it is also permissible to tow a Tesla with one axle lifted on a tow truck, and other side placed on top of a wheel dolly. Of course, a flat-tow would be preferable to the dolly setup, but it's interesting how Tesla specifically addresses that possibility while Porsche does not.
Are EVs harder to tow or flat tow? Some are, some are not: automakers should establish a common standard for doing that.
