Hybrids are starting to make inroads in Europe, but diesel is still king on the Continent, and any automotive brand that hopes to have any significant market share knows it must offer a diesel engine option. For decades, Cadillac has struggled to gain traction in the European market, where most of the established luxury brands are based. After the company suspended development on a turbodiesel V-6 for the European-market CTS sedan in 2009, Dave Leone, GM chief engineer for performance cars, told WardsAuto a diesel engine for European-market Cadillac models can't come soon enough, particularly in regard to the new CTS and ATS models.
Prior to General Motors' bankruptcy, Cadillac was working on a 3.0-liter turbodiesel to go into the CTS sedan. That engine was ultimately scuttled for the CTS, but development work continued on it by parent company VM Motori, at the time a 50/50 joint venture between Fiat and GM. An evolution of that engine has now come to market in the form of the 3.0-liter V-6 EcoDiesel offered in the Jeep Grand Cherokee and Ram 1500.
It's unknown how much of a role diesel engines will play in Cadillac's North American lineup, but with GM starting to tiptoe back into light-duty diesels with the Chevrolet Cruze, and the upcoming Chevrolet Colorado and GMC Canyon midsize trucks, it's not inconceivable that we might see more diesel-powered Cadillac models in the States. GM representatives have been particularly tight-lipped about the possibility of reviving the 4.5-liter Duramax V-8 project that came within a year of going into production before being canceled prior to the bankruptcy. We wouldn't mind seeing that as an option in the Escalade.
