The new car would be developed specifically as a premium Cadillac model. Nonetheless, Cadillac general manager Jim Taylor is concerned that American consumers might not yet be ready to accept a Cadillac without at least the option of a V6. The new model would likely use the 2.0L direct injected turbo as used in the Pontiac Solstice GXP. At this point it appears that Cadillac will likely offer the 6-cylinder option, although if gas prices resume their upward spiral that could well change. If a V6 is part of the plan, it will probably be a rumored smaller displacement 3.0L version of the 3.6L currently offered in the CTS.
