The XT4 plug-in will be revealed this week and will go on sale this Fall. The base trim of the vehicle will be a typical ICE. But a (likely) plug-in model has been spotted testing a few times in the past year. https://insideevs.com/cadillac-xt4-spy-shots-show-possible-phev/ Bloomberg casually mentioned in an article last week on the upcoming New York International Autoshow that the XT4: "will share the same platform as the Chevrolet Malibu and will be among the first to utilize Cadillac’s forthcoming hybrid and electric technologies." At the Detroit Auto Show this year, Cadillac President Johan de Nysschen said that the brand would: "get a “disproportionate share” of the 20 all-electric vehicles that GM plans to bring to market globally by 2023, he said. A few years after the first electric Cadillac goes on sale, the brand will have some kind of self-driving vehicle in the lineup as well. “Cadillac in the future will be the technology lead brand for General Motors,” de Nysschen said. “Technologies will debut in Cadillac first and then cascade down to the other brands.” https://www.bloomberg.com/news/articles/2018-03-23/small-suvs-will-hog-the-spotlight-at-the-new-york-auto-show I wonder if they're going to announce the plug-in model this year or next. I don't expect the Plug-In to be available at launch of the vehicle. But I would love to see an announcement at some point this year! Hopefully this week. Don't disappoint, Caddy! It's about time one of the GM brands put out a Voltec SUV. Lots of people have been waiting for a very long time!
