The 2010 Detroit Auto Show will witness the debut of the Cadillac XTS Platinum Concept sedan, a plug-in hybrid which will mark the next level of Cadillac’s illustrious Platinum Edition products.

Featuring a minimalist-looking instrument panel in the cabin of the all-wheel-drive XTS Platinum Concept clearly reflects Cadillac’s vision for its future vehicles, which will largely do away with the traditional buttons, knobs and dials.

Equipped with a 3.6-liter direct-injection gasoline engine, the XTS Platinum boasts a host of luxury amenities that make the sedan appear like “a personal headquarters, built for efficiency, luxury, and connectivity.”

In a statement, Cadillac said: “The concept previews a new integration philosophy guiding the development of future models with respect to in-car electronics. The XTS Platinum Concept previews this strategy via the minimization of traditional buttons and switches.”

Thanks to the plug-in hybrid propulsion system, the XTS Platinum brags approximately 350 horsepower and 295 pound-feet of torque. In addition, the antilock brakes, stability control and traction control supplement the other details of the drivetrain, along with the outside design inclusions like 20-inch tires and wheels; a rear spoiler; vertical, swiveling LED head-lights; and vertical tail-lights.

A production-spec XTS, which will be 203.5-inch long and have a 111.7-inch wheelbase, would likely hit the markets in 2012, with the car’s assembly to begin in late 2011 at GM’s Oshawa, Ontario, plant.
