When it comes to diesel technology, you can’t fault Mazda for being persistent. For example, when it wanted to make the most of its groundbreaking Skyactiv engine technology, it spent the best part of a decade trying to make a version for the US market. Here, Mazda first promised its Skyactiv-D engine in the early 2010s, but it would be the end of the decade before it finally arrived on US shores in customer-ready form. But when it did arrive, the marketplace was entirely different, and although consumer demand became the official reason for the demise of Mazda’s plan, several other significant factors also came into the equation.
