The Cadillac CT4 is the luxury brand's latest appeal to youthful car shoppers who aren't ready to give up on sport sedans. This subcompact car replaces the
ATS as Caddy's entry-level model and, like that outgoing car, will take on small four-doors from German competitors. With the CT4, Cadillac buyers will have access to a car that blends upscale looks and leading-edge tech with track-ready performance.
