Analysts and journalists alike have been carefully watching Mazda, which will is poised to become the first Japanese automaker to try to sell a modern diesel in the United States. Honda had previous suggested that its Acura TSX would be a good candidate for a diesel powertrain in this market, but the automaker canned the idea after deciding that demand would be low.
Mazda has shied away from hybrid powertrains for most of its models - rare Tribute Hybrids stand as an exception - although the company's CEO recently confirmed that hybrids using Toyota tech will be a stepping stone toward EVs. In the meantime, the automaker will look toward diesel powertrains to boost its relatively low line-wide mpg figures.
Mazda now has one of the world's most advanced diesel engines, its SKY-D offering, which bumped fuel economy up more than 30 percent over the engine family it replaced.
As for likely candidates for a diesel motor? Bigger vehicles, like the CX-7 and CX-9 stand to benefit the most, but the company has already said that a SKY-D-equipped model will net 43 mpg, which suggests that a diesel-powered Mazda3 is on its way.
Look for more information to leak out of Mazda's normally silent executives closer to the New York show.
