The Cadillac XTS doesn't come with a V8?!

Tonight, I deliver the Phaeton to the happy new owners. They are a sweet couple with a nice collection of 1970s GM boats. Think Coupes de Ville and Buick Estates. Just before they checked out my car last weekend, they test drove the new Cadillac XTS. I was surprised to learn that the big Caddy is only offered with a V6. Moreover, the Chinese market XTS only comes with a turbo four. This is bordering on blaspheme.
