For many, they didn't even know it was sold here to begin with.
While diesel as a fuel for passenger vehicles is being squashed by governments worldwide, it never really took off in the US. As far back as 2012, Mazda started promising diesel options, and the Mazda6 and CX-5 were slated to get the torquey Skyactiv-D diesel engine. The CX-5 had diesel as an option since 2019 on Mazda's website, but the Mazda6 version has been held back as a "future vehicle." Now, both models have disappeared from view, and we've had confirmation Mazda has killed plans to offer the Skyactiv-D diesel engine completely, making yet another manufacturer to cull the fuel from its lineup.
It's not really a surprise diesel is dead for Mazda, and in hindsight, the automaker was right not to rush into pushing the alternative engine into production on the Mazda6. Mazda wouldn't confirm sales figures for the CX-5 diesel when we reached out, but we know they aren't strong. Instead, the Japanese automaker told us: "After evaluating consumer demand, Mazda will no longer offer the Skyactiv-D diesel engine in the US market, Mazda will continue to advance its diesel technology globally as part of our Multi-Solution Powertrain Strategy." That strategy will see a new engine architecture born that will spawn a new inline-six that will have gasoline, diesel, and Skyactiv-X variants that can be used in a variety of models.
Another problem dissuading Americans from adopting diesel as a passenger car fuel has been price. In Europe, it's been a cheaper option, but over here, it's more expensive. Add to that the fact that Mazda's CX-5 with the Skyactiv-D diesel engine retailed at over $40,000 and returned an EPA estimated 29 mpg overall, it's not a shock it was retired in the CX-5 or that the Mazda6 version never made it to our shores. Now, with the rise of all-electric and hydrogen-based vehicles, we can probably declare the diesel revolution as dead in the water. Let's hope that the more exciting inline-six plans take deeper root.
