Mazda's Kiyoshi Fujiwara has revealed the company plans to offer diesel engines in the United States has suffered another setback.

Mazda was slated to launch a diesel-powered Mazda6 in the United States in the second half of 2013 but it had problems meeting emission standards.  The company eventually fixed the issues but the reworked engine was considered to lackluster to meet customer expectations.

Fast forward to today and it looks there will be further delays as Mazda's Kiyoshi Fujiwara has told Automotive News the increased scrutiny of diesel engines in the wake of the Volkswagen scandal will "cause a delay in plans for everybody looking to sell diesel cars in the U.S. market."  As he explained, "Tests are going to be tougher" and regulators "no longer trust companies" so they're not telling them about the new testing procedures.

Despite the issues, Fujiwara says the company is still committed to launching a diesel model in the United States but he can't give a timeframe at this point.

Interestingly, back in 2014, Mazda North America CEO Jim O’Sullivan said the company was delaying the diesel engine because an underperforming engine would hurt both the brand and the image of diesel engines in the United States. Of course, in hindsight, an underperforming engine wouldn't have been nearly as bad as Volkswagen's transgressions.
