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:
- 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.
