2015 Cadillac XTS: What's New, Specs & Features
Last updated August 4, 2026
The 2015 Cadillac XTS is largely a carryover, with standard navigation on the Luxury Collection as the most important change. Platinum models also gain revised rear-seat controls, but the engines, body, and core technology carry over.
About the 2015 Cadillac XTS
1st generation XTS (2013-2019), 2015 model year; third year of the generation and still in its pre-2018 styling form.
Cadillac positioned the XTS as a large luxury sedan that mixes dramatic styling, a quiet ride, lots of passenger space, and a long list of technology features. More than a sport sedan, it was meant to feel like a modern Cadillac cruiser: roomy in the back seat, easy to live with every day, and richer in standard chassis hardware than many rivals. The Vsport versions added real straight-line performance without changing that comfort-first character.
The 2015 XTS lineup ranges from the comfort-focused Luxury Collection to the technology-rich Premium Collection, which has a digital instrument cluster, head-up display, and upgraded Bose audio. Vsport models pair a twin-turbo V6 with AWD, while Platinum versions focus on richer cabin materials and rear-seat amenities.

2015 Cadillac XTS
(165 reviews)
“I love my new vehicle and so does my sister. We both purchased a new Cadillac XTS.”
“While I am very happy with my new car, there are still a couple of design issues that can be improved upon. First, the display panel constantly smudges. It is impossible to keep it clean. The iPod connections do not properly read my equipment. I have tried using different iPods; however, I still experience the same problem.”
