Will Mazda sell diesel hybrids in Japan in 2016?

Could the "Zoom Zoom" automaker start making hybrids that go "glug glug glug"? Mazda, known for its fuel-efficient Skyactiv engine line, will be the first Japanese automaker to make a diesel-hybrid vehicle for Japan and Europe. According to the Yomiuri Shimbun, Mazda may start making its oil-burning hybrids as soon as 2016, and the powertrain may reach fuel efficiency levels of as much as 95 miles per gallon (one the more lenient Japanese driving cycle). That'd make such a vehicle line about 30 percent more fuel-efficient than standard diesels and about eight percent more fuel efficient that the Toyota Prius C compact hybrid (known as the Aqua in Japan). Mazda has been dismissive of hybrid and electric powertrains, instead focusing on Skyactiv technology to maximize fuel efficiency from conventional gas-powered engines. Diesel powertrains account for about half of the light-duty vehicles sold in Europe each year, while Japan's diesel sales of 76,000 vehicles last year were about three times as many as were sold there in 2012. In January, Mazda said that it would delay the introduction of its Skyactiv-D diesel engine from what was to be a spring 2014 debut. The reason was to fine-tune the engine's performance/fuel economy balance. Mazda representatives didn't immediately respond to a request for comment from AutoblogGreen about the diesel hybrids.

Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.

Mazda previews 2016 Miata Global MX-5 Cup racer

At this point, we all know that the Mazda MX-5 Miata is a highly capable racing platform. Mazda even claims that the car is the most road-raced model in the world. Fittingly, then, the Japanese brand is making a huge announcement about the future of motorsport for its next-generation convertible. The MX-5 Cup is going worldwide in 2016 as the MX-5 Global Cup, and all of the racers are getting behind the wheel of the upcoming fourth-gen Miata, similar to the gorgeous redhead pictured above.
"It has long been our goal to see Mazda fans around the world competing in identical MX-5s, and the launch of the 2016 MX-5 Miata is the perfect time to make this goal a reality," said Masahiro Moro, Managing Executive Officer in charge of Global Sales, Marketing and Customer Service for Mazda in the company's announcement.
The racing version makes its grand debut at this year's SEMA show, although at the moment it's really more of a concept. Mazda confirms that the racer uses the 2.0-liter SkyActiv four-cylinder, but the other important parts like tires, suspension and safety equipment are not yet determined. The cars "will be sold ready to race from a single supplier," according to automaker's announcement for the series.
