Cadillac’s electric transformation is definitely not going as planned. Sure, General Motors' luxury brand already has the Optiq, Lyriq, Vistiq and Escalade IQ, not to mention the Celestiq ultra-high-luxury sedan, but the goal to become an EV-only company has long been abandoned. And now it appears that some discontinued gas-powered models are about to return. More specifically, we are talking about the Cadillac XT6.
