Cadillac XT6 Luggage Test | How much fits behind the third-row?

The 2020 Cadillac XT6 may share its platform with the Buick Enclave and other full-size GM crossovers, but it's no badge-engineering job. That much is obvious just by looking at it, but for the purposes of this post, there's quite the difference in terms of cargo capacity. The jumbo Enclave has 23.6 cubic feet of space behind its raised third row, which is more than any other three-row crossover — often by quite a lot. By contrast, the XT6 has 12.6 cubic feet, which puts it well south of the Hyundai Palisades and even Mazda CX-9s of the world. Of course, the XT6 does not attend that party. It's a swankier, pricier luxury model. It compares to the Lincoln Aviator (18.3 cubic feet), and Volvo XC90 and Acura MDX (both 15.8 cubic feet). So yeah, it's smaller than those, too.

Now, the XT6 balances this cargo deficiency with a genuinely spacious, adult-friendly third-row seat. People will be quite happy back there. However, the fact remains that not much of their stuff will be able to come along for the ride. How much is "not much," though? Well, let's take a closer look.

That looks small up there, and it is small. There are some bonus areas, however, with a deep-ish bin on the left and a sizable under-floor bin. Unfortunately, that under-floor space really doesn't help you in terms of luggage (unlike in the CX-9, as just one example).
