Cadillac’s flagship CT6 is an impressive luxury car. Plush, roomy, quick, agile and high-tech, it just might be worthy of Cadillac's old slogan: “Standard of the World.” The CT6’s stellar Road Test score certainly ranks it among the best sedans. Our qualms revolve around a few interior quibbles, and the brand’s less-than-stellar predicted reliability rating. The CT6 slots in between two defined sedan classes.
