Facelifted in 2017, the XTS gets a tauter front end and a slightly more contemporary presentation, but keeps its primary mission: carrying passengers in great comfort without abandoning the Cadillac style. It is a straight-line car, a silence car, a wide-seat car - closer in spirit to a very well-appointed Lexus ES than to a European saloon with a demonstrative chassis.
The powertrains change little on this phase, still centering on the 3.6 V6 LFX, the 2.0 turbo LTG on certain versions and the rare twin-turbo V-Sport LF3 for those who want more pull. The facelift benefits mainly from a better-finished presentation and enriched equipment. Today, the relevant question is not the spec sheet but the condition of the running gear, the CUE electronics and the adaptive suspension.
