I think the “fun” version of the Roadster hasn’t been announced yet. If the plaid is a GT Autobahn cruiser, then the Roadster is the GT cruiser light + distance. We still expect it to use a double stack battery right?…I don't know how they are going to build a fun car with a huge battery. It looks like the Plaid battery already weighs 1200 lbs.
It will be interesting to see what common overlap of new parts there are on Roadster and Highland.
