Not only does it wear at least the outline of the brand's new, broader crest, it has the same front air dam with continuous chrome strip found on the coupe. The only real difference is that it has the somewhat taller side view mirrors from the sedan, rather than the narrower, longer ones from the coupe. Around back, the changes are harder to spot because the test car is outfitted with an unpainted lower bumper. However, it seems to lack the chrome strip that offsets the lower portion of the coupe from the sedan.
The ATS sedan is already a looker, but it is good to see Cadillac is taking a second pass using what it learned on the coupe. There's no word yet on when this revised sedan is going to hit the streets – let alone what changes will take place beneath the skin – but we're thinking it looks about right for 2015.
