The 2018 Cadillac CT6 features a trunk space of 15.3 cu.ft. which seems fine for a sedan. There's enough room available to carry the luggage of five for a weekend. For a better perspective, the trunk can hold at least two large suitcases and a few small backpacks as well. For additional storage space, you can further lower the rear seats to push in a couple of more big boxes inside the car.
