#Skyactiv-d

When it was rumors and innuendo, when it was delayed, when it was confirmed but unattainable, when it was launched, when it was actually under the hood of a vehicle we could drive on this continent, we’ve covered the story of Mazda’s diesel engine.

It’s a 2.2-liter turbocharged four-cylinder with a measly 168 horsepower but a stirring 290 lb-ft of stump-pulling torque. It resides not in the Mazda 6 for which it was originally intended but rather the highly acclaimed Mazda CX-5. It’s available only in the CX-5’s top-spec Signature trim, and only then at a $4,110 premium that drives the price up to an eye-watering $41,000. Its fuel economy gains are so minimal that the economic case for the CX-5 diesel is nonexistent.

And after one model year and just enough demand to help (in some small way) propel the CX-5 to yet another record sales year, the Mazda CX-5 diesel is missing. Truant. Unaccounted for.

Moreover, there’s no timetable for the CX-5 diesel’s return.

Mazda has certainly bent over backwards to get its new diesel to the U.S. market. Originally slated to premiere inside the 2017 CX-5, Mazda’s Skyactiv-D failed to receive approval from the Environmental Protection Agency. We’ve followed the story for a while, including when it concerned the Mazda 6, sometimes wondering why the company would even bother pursuing such an endeavor.

In addition to appeasing the EPA, Mazda also needed to satisfy thrifty diesel buyers. But it didn’t look like the 2.2-liter Skyactiv-D had the specs necessary to positively impact CX-5 sales. In development for a while and twice stalled by regulators, the end result of this engine overhaul is a compromised powerplant that’s even weaker than we feared, debuting miserably late with a premium price tag.

It’s hard not to feel a little sorry for Mazda. Back when the Skyactiv-D was in the early phases of development, Volkswagen was proving to the world that diesels could deliver… until that turned out to be a huge, unfixable lie.

The diesel version of Mazda’s wildly popular CX-5 crossover was originally supposed to land on these shores in late 2017, but the plan hit a snag. As such, we’re still waiting. But the model’s appearance now seems imminent.

Having cleared the Environmental Protection Agency’s stringent testing regimen, we now know exactly what fuel economy to expect from the CX-5 and its compression ignition 2.2-liter Skyactiv-D inline-four. The question is: is the CX-5 diesel thrifty enough?

Mazda announced 11 months ago that the company “will introduce a diesel engine option to the North American market,” with the revamped CX-5, launched in the 2017 model year.

We’d heard such claims before. Three years ago, we were still waiting on the launch of the diesel-powered Mazda 6, at least until Mazda gave up on that idea. But Mazda’s insistence this time around produced less doubt. Mazda even revealed that the automaker felt it could generate 10 percent of CX-5 sales with the diesel model.

But last month, we began to wonder about Mazda’s claims of delivering a 2017 Mazda CX-5 Diesel in the second-half of 2017. The second-half, as you may have noticed, is quickly drawing to a close. Moreover, Mazda wouldn’t offer up any timing, saying only that, “We are working with the EPA and CARB and will have more information in the future.”

Mazda still won’t offer up any timing details. But TTAC’s resident government filing investigator, Bozi Tatarevic, came across some very interesting details at NHTSA.gov that reaffirm the forthcoming 2018 Mazda CX-5 Diesel.

The Mazda6 diesel, long awaited as the first major competitor to the Volkswagen Passat TDI, is being delayed due to difficulties meeting emissions standards without the need for after-treatment. TTAC has learned that Mazda is changing their strategy to incorporate an after-treatment, to help meet both emissions and performance benchmarks.

Mazda is delaying the launch of the North American-spec SKYACTIV-D diesel engine, as engineers grapple with getting the engine to meet both emissions and performance benchmarks in North American spec.
