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 is developing gas and diesel inline-six engines

Once the favored engine configuration for luxury and high-performance cars, the inline-six suffered a bit when the transverse (east-west) engine configuration became popular during the shift to front-wheel drive cars. The packaging benefits are obvious – no driveshaft or transmission intruding on passenger space or rear differential on cargo volume, plus turning the engine 90 degrees meant the front of the car could be shorter. But the inline-six is slowly, slowly crawling out of near-obsolescence, notably in BMW, Jaguar-Land Rover and Mercedes-Benz products. Add Mazda to that mix: An investor report first spotted by Jalopnik and confirmed by Mazda reveals that the company is developing a Skyactiv-X and Skyactiv-D inline-six that will be installed longitudinally (north-south) in a new "Large Architecture" platform. Before reading any further, let's catch up on the Skyactiv-X and -D technologies. The former basically burns gasoline like diesel, providing some benefits and advantages of both types of combustion - here's an explainer on how that all works. We drove a prototype 2.0-liter Skyactiv-X 4-cylinder engine in a Mazda3 mule, too. And the Skyactiv-D series of engines is a comparatively typical turbodiesel. Mazda has a 2.2-liter turbodiesel inline-4 that has had a long and convoluted development and certification process, but is finally showing up in the 2019 CX-5. Since Mazda has implemented these technologies in existing four-cylinder engines, we would assume that the new Skyactiv engines will be "modular" – that is to say, they'll essentially be the existing engines with two extra cylinders, rather than an entirely new design. Jaguar-Land Rover is doing a similar thing with its Ingenium engine family. Assuming the Mazda engines will be modular would mean they'll be roughly 3.0-liter units, which is a common displacement for modern inline-sixes. And as we mentioned eariler, they'll be arranged longitudinally, unlike any other Mazda save the MX-5 Miata (and the long-departed rotaries), in a new vehicle architecture. As part of a medium-term plan over the next six years, Mazda will develop some unspecified vehicles on what it calls the "Large Architecture". These vehicles will have 48V mild hybrid and PHEV capabilities, and be able to use a version of Mazda's i-Activ AWD system. Why do this at all?

Mazda recalls 1.37 million older vehicles for ignition switch short [UPDATE]

UPDATE: Mazda has confirmed to Autoblog that NHTSA's figures and list of effected models are accurate. Mazda is recalling 1,368,500 older vehicles in the US that date as far back as the late '80s because a potential short circuit in the ignition switch could cause a fire. According to the National Highway Traffic Safety Administration, the models include: 1990-1995 323 1993-1998 626 1993-1995 929 1989-1998 MPV 1993-1997 MX-6 1992-1993 MX-3 1990-1998 Protege Mazda reports that over time the grease around the switch's contact points can carbonize and become conductive, which can eventually lead to a short circuit. In some cases this results in smoke, but it could also lead to a fire. According to company spokesperson Tamara Mlynarczyk to Autoblog, there're no accidents, injuries, or fires in the US. Once the vehicle is running, the potential fault also doesn't affect drivability. Documents from NHTSA (as a PDF), indicate there was a fire in one of these vehicles in Japan in 2002 that could have been linked to this issue. The recall should begin in December. In its announcement of the issue below, Mazda reports 1.2 million vehicles affected and includes the 1990-1996 323/Protege. Autoblog has reached out to the company to understand the discrepancy.

In the affected vehicles, grease applied to the contact points inside the ignition switch may become conductive and overheat. CONSEQUENCE: If the ignition switch overheats there would be an increased risk of a fire. REMEDY: Mazda will notify owners, and dealers will replace the ignition switch, free of charge. The recall is expected to begin December 15, 2015. Owners may contact Mazda Customer Experience Center at 1-800-222-5500, option#6. Mazda's number for this recall is 8715J.
