Mazda has delayed the North America launch of its 2.2 liter SKYACTIV-D clean diesel engine, from its intended debut this Spring, saying SKYACTIV-D can meet emission regulation requirements without the use of a NOx after-treatment system, but it was decided that further development is required to deliver the right balance between fuel economy and Mazda-appropriate driving performance.
I was looking forward to this introduction, especially after seeing that Sam's Club sells diesel fuel for about 16 percent more than regular unleaded gas which makes the cost saving - fuel efficiency equation make sense. Mazda showed off it's clean diesel at the 2012 Los Angeles Auto Show where Mazda North America President Jim O'Sullivan discussed diesel in a SaxtonOnCars interview.
