Solely because he said "PLUG-IN" and not "CT6 EV" I'd take a Vegas bet it means the existing CT6...If we dive deeper, according to insideevs, the CT6 PHEV was first sold last month and sold a grand total of six so they could still be trickling into dealerships and so while this was after the CT6 PHEV was released, it isn't yet fully rolled out...Even deeper, they put the battery in the trunk, you'd imagine if they were wanting a larger battery to go in the floor for a BEV version the PHEV would also have had its battery installed in the floor...
