Over the past decade the effort to remake Cadillac into a modern luxury brand to compete with the likes of BMW, Audi and Mercedes-Benz has only been partially successful. The Escalade and CTS have been hits but the Cadillac has no smaller high volume model to compete with the 3 series and the larger STS and DTS are on their way out. The first phase of Cadillac's effort to flesh out the lineup debuts in Detroit today in the shape of the XTS concept.

The XTS is currently a concept but it's expected to go into production as a flagship in early 2012. Its front styling draws heavily on the 2003 Sixteen concept but instead of a massive V16 engine, the new car gets a direct injected V6 and a plug-in hybrid system. The hybrid system is based on the two-mode hybrid technology available in GM's full-size SUVs and pickup trucks but modified for installation in a car. The nickel metal hydride battery is replaced by a lithium ion pack that allows more electric-only or electrically boosted hybrid driving. The plug-in hybrid was originally planned to debut in the now canceled Saturn Vue in 2011 but will now instead go into one of GM's premium vehicles. The most likely candidates are either the XTS or the SRX crossover from Cadillac.
