American luxury automakers have been without serious players in the large mid-size SUV class for a long, long time. The Lincoln MKT was never a hit, given its ungainly styling and awkward interior packaging. And if you wanted a big mid-size Cadillac SUV, you were out of luck — it didn’t exist. You could buy an SRX two-row crossover, which eventually became the XT5, or a big ol’ Escalade truck. Elsewhere, the Mercedes-Benz GLS, Infiniti QX60 and Acura MDX filled this gap. For 2020, the Americans are back with two new models aimed at the big mid-size, three-row luxury crossover SUV class: the 2020 Cadillac XT6 and the 2020 Lincoln Aviator. While we won’t get behind the wheel of these new money wagons for a few more months, we compared the two at the 2019 Chicago Auto Show to see how they stack up in a few key areas.
