What you're looking at is the production version of the 2013 Cadillac XTS, the full-size luxury yacht that will be doing double duty when it goes on sale next year to replace both the DTS and STS.
We were all set to see the XTS debut next week at the LA Auto Show, but Cadillac beat us to the punch when it accidentally slipped the above image into a slide show on the company's consumer-facing website. The image has since been removed, but as the Internet proves time and again, nothing is ever forgotten.
The biggest thing going for the new XTS, besides its literal size, is the debut of Cadillac's new CUE infotainment system, which we gave you a hands on tour of earlier today. As for its looks, the production XTS appears to be almost identical to the XTS concept that debuted earlier this year at the 2011 Detroit Auto Show. The XTS concept is stunning to behold in person, though in pictures its design can appear too simple, lacking the visual impact that should be present in Cadillac's range-topping four-door. We'll have to wait until next week to see if the production XTS imparts the same first impression.
UPDATE: Cadillac has released the official image of the 2013 XTS that was accidentally leaked onto its website.
