2020 Cadillac CT6 vs. Its Competition

2020 Cadillac CT6
Aaron Cole Aaron Cole Managing Editor

The Cadillac CT6 rivals—and has been eclipsed by—German competitors from Audi, Mercedes, and BMW.

Nearly all have more tech and available features, although the CT6 was nearly as comfortable as the bunch.

The Acura RLX is similarly unloved, but a hybrid powertrain keeps that full-size sedan interesting/relevant.

The Volvo S90 is beautiful but smaller.

We like its tech and elegant approach.
