Fuel in the U.S. is really cheap compared to most of the rest of the world. That and the US
EPA has an apparent grudge against diesel engines that requires more emission control stuff than other markets which makes the initial cost of the diesel option even higher. On top of that, petrol engined cars have gotten vastly more efficient than they used to be. Diesels just don't make economic sense for a lot of people here.
