Currently only fifteen percent of all Cadillac sales are V-8s and that includes the Escalade and XLR. With the introduction of the direct-injected version of the V-6 this year, the engine's output is rated at 304hp compared to 320 for the 4.6L V-8 and the V-6 is more efficient and lighter. Going forward Cadillac will instead focus on the DI V-6 possibly added turbocharging at some point. For the applications where a V-8 is deemed necessary - like the Escalade or the XLR - they will use variants of the small-block V-8 instead. Even this engine may well get direct injection at some point and it's being tested now.
