Now, with Mazda , Mercedes-Benz, and even Chevrolet slated to accomplish four-cylinder diesels back to the U.S. within the next couple of years, the playing province is set to change significantly.
Mazda's all-new 2.2-liter Sky-D sing-diesel engine, when it makes its debut in a year or two, will almost certainly be the cleanest of the lot.
With a absolutely new clean-slate design and some innovative engineering, the apparatus solves some longtime design constraints—and makes an affecting 310 pound-feet of torque and about 170 horsepower.
While we don't have parts-per-million numbers and the like for the new locomotive, the initial information we've gleaned about the Sky-D engine will most certainly post it at the top of the clean list—and likely, significantly cleaner than the fashionable TDI. And, according to Mazda, it goes about 20 percent farther on a gallon of diesel.
