Nothing in VW is truly bespoke. So as this gets detailed I expect we will see this be related to the other high end VW group (are they still called VAG? I have not been paying attention) EVs in multiple ways.

Edit to add : reading more to the recent org changes in VW, it seems that Bugatti, and Rimac are now semi independent under Porsche. But notably Bentley and Lamborghini are not part of this group. So there may be some separation.
