How would you feel about a Cadillac with a diesel engine? Those of you in America shouldn't bother answering that question, however – it's strictly for the Europeans. At the Los Angeles Auto Show, Cadillac's VP of marketing said that a diesel is "under consideration for vehicles sold outside the United States," with its U.S. chances going only so far as "a potential hedge." We've heard something like this since at least 2007 from the company. Is it for real this time?

When committing to the best fight against its rivals overseas, Cadillac's rep said, "if that means making the right powertrain choices, then those are the choices we will have to make." No mention was made of Opel's diesels or whether General Motors would choose to develop something new, but the German subsidiary has done well with oil-burners in the Insignia, and a trial of diesels in Caddys could help use up the allotment that Saab won't necessarily be needing.
