Thankfully, the VW group will actually be okay - they've tasked Porsche's engineers with electrification of all the companies owned by the group.
The Taycan will be built on the J1 platform (Porsche controlled/built). Porsche is developing 3 different packages for other car makers: the SPE (Sport platform electric) for Lamborghini, and then they’re developing a PPE (Premium Platform Electric) for Audi and Mercedes, and finally, they’ll have the MEB (modular electrification box) which is a kit for anyone else who wants electric drivetrains (VW, others)
