But I guess not because these leaked images from China show a facelifted XTS for 2018. The front facia seems to take from the CTS and CT6.
The rear is... I don’t know. Weird to say the least. No word on any engine upgrades or different options. But I found it weird that in China their sole engine option for the XTS is a 2.0 liter 4. We should see this refresh soon.
