The picture you see here is the brand new 2013 Cadillac XTS. The picture was accidentally posted on Cadillac's home page today before being taken off. Luckily, a reader from Jalopnik captured the picture for all of us to see. Since then, Cadillac has confirmed this will be the XTS we see next week at the LA Auto Show.
The production model is almost a carbon copy of the XTS Platinum concept shown at last year's Detroit Auto Show, with a different design for head and foglights. The XTS will also have Cadillac's new CUE infotainment system.
Edit: GM has since officially released the XTS photograph. I've updated the photo in this article with the GM Media supplied one - DD
