Beneath that eclectic collection of camouflage resides an early prototype of the next flagship of the Cadillac fleet -- a vehicle GM's luxury division first presented as the XTS Platinum Concept at the 2010 Detroit Auto Show. While much information about this de facto even-higher-end replacement for its current DTS and STS models remains classified, we do know that the production version of the 2013 Cadillac XTS will be spun from a stretched version of GM's Epsilon II platform -- architecture that currently also underpins the Buick LaCrosse -- and that it's expected to start rolling out of the automaker's Oshawa assembly facility in Ontario, Canada, starting sometime next spring.
Despite its full-body cover-up, this prototype appears to retain a good bit of the basic styling and proportions seen on its one-off predecessor. Our current best information indicates that the standard powerplant for the 2013 Cadillac XTS will be a version of GM's 3.6-liter direct-injected V6; although a turbocharged 3.0-liter six also is rumored, as are both front-drive and all-wheel-drive configurations. Interestingly enough, one of the items not cloaked on this prototype are its Brembo brakes, a bit of hardware that seems to open the possibility of an XTS-V variant turning up at some point in the future.
