Cadillac has not released much actual news about the upcoming DTS/STS replacement sedan.  It may or may not be named “XTS”.  The internal designation is probably GM 166.

Logically, let’s look at what is likely:

Engines:

• Base model 3.6L DOHC DI V6, with 304 hp.  Hybrid model to follow after release.

• Performance Sedan: L99 6.2L V8 with 390 hp.  The return of Active Fuel Management to Cadillac. AFM Lifters in cylinders 1,4,6, and 7 and the AFM control system enables V4 operation at engine operating conditions where V4 mode is more efficient.

Chassis: Long wheel base Epsilon II w/ 115″ wheelbase, or 3″ more rear leg room than the CTS sedan. FWD or optional AWD, so it should definitely be an all-season selection.  Ultra-high strength steel in a premium chassis for super rigidity.

Interior: Hand stitched leather. Elegant, sweeping interior with infotainment system, and navigation.

Exterior:  Styling hints from the Cadillac Sixteen concept.  Love it or hate it elegance.

Pricing:  US$45-$65K, with later Hybrid and Platinum lines at a premium.
