Mazda Unveils New Skyactiv-D 2.2L Diesel Engine, Destined For U.S. Market

We already have had a taste of Mazda’s new Skyactiv fuel-saving powertrain technology. Now, the automaker has taken the wraps off of its new Skyactiv-D 2.2 turbocharged inline-four cylinder diesel, which should have offer torque comparable to a gasoline V-6 but deliver much better fuel economy.
Mazda is launching the new engine in the Japanese-spec CX-5 compact crossover. Interestingly, Japan has long been market whose buyers have generally resisted diesel-powered vehicles. In the CX-5, the Skyactiv-D 2.2-liter turbocharged inline-four cylinder will pack a stump-pulling 310 lb-ft of torque, and Mazda expects fuel economy gains of around 30 percent when compared to a similar gasoline-powered engine.
The Skyactiv-D also uses a low 14:1 compression ratio that allows the 2.2-liter to avoid costly NOx treatment systems (like the “AdBlue” urea injection solution used by BMW and Mercedes-Benz). Coupled with Mazda’s i-Stop automatic start/stop system, the new diesel mill will comply with the most stringent emissions regulations, including Euro6 in Europe and Tier2Bin5 in North America.
But will we ever see the Skyactiv-D engine in our market? The short answer is yes: Mazda has previously promised to begin selling diesels stateside in about 18 months. While Mazda says that it has not decided on which U.S.-market vehicles will receive the Skyactiv-D 2.2, that date is not long after the CX-5 will go on sale here, and just before we expect the next-generation Mazda6 to hit dealerships.
