Mazda Sky-D Concept Diesel Engine To Get 43 MPG On Highway

Mazda, besides recently announcing plans to license hybrid technology from Toyota, also let word be known this week at the auto show in New York it will be bringing to the United States in 2012 the clean diesel Sky-D version of its new Sky Concept fuel-efficient powertrains. It is the goal of Mazda through the use of engines like this to improve ” the average fuel economy of its global line-up by 30 percent, with a drop in CO2 emissions of 23 percent (compared to 2008) by the year 2015.”

Mazda said in making this announcement that the Sky-D diesel engine will be incorporated into its next-generation mid-sized diesel car to deliver what it believes will be “highway fuel economy of up to 43 miles per gallon – which is better than today’s mid-sized hybrids – and a 20-percent improvement in fuel efficiency over Mazda’s current 2.2-liter diesel.” The engine will be designed to meet the tough Tier 2 BIN 5 regulations and, because of the auto manufacturer’s catalyst technology, will not have to ” require urea after-treatment to meet the strict North American emissions standards.”

Prior the the Sky-D, Mazda will introduce a regular, more fuel-efficient Sky-G engine. This particular engine, when it debuts as early as next year, is expected to boost fuel efficiency by approximately 15 percent while also increasing engine power. It, along with the Sky-D, will also be mated to the company’s new Sky-Drive transmission to “improve fuel economy by an additional five percent, while achieving a direct-performance feel like that of a dual-clutch transmission.”

    Thank you Mazda, Audi, VW, Mercedes, BMW and (soon) Mahindra. Your vehicles will finally show a skeptical public here that clean diesel technology is the way to go. I’m especially excited about the Mahindra compact pickups – it’s been a long time since we’ve seen a fresh face in this vehicle segment.
