Mazda6 diesel engine delayed over low performance, still coming

Oh Mazda... we had many hopes for the promised diesel four-cylinder in the Mazda6, but those have remained largely unfulfilled, as the oil-burning powerplant has failed to appear on dealer lots following its 2012 LA Auto Show announcement. Despite engineering issues that forced the company to announce that the program was delayed back in September 2013, Mazda remains adamant that the 2.2-liter Skyactiv-D is still coming to our shores. "We're still very much committed to diesel," Mazda's North American CEO, Jim O'Sullivan, told Automotive News. "We are still working on getting the performance aspects up to where we want them, and we do have a plan – an engineering road map – to get it done." According to AN, Mazda's initial plan with the 2.2-liter diesel was to build an engine so clean it could get by without an aftertreatment system, which generally accounts for the price premium of diesel engines versus their gas counterparts. The new system has come with performance issues, though, necessitating the delays. "If [we were] a commodity brand and didn't care about that, it would be on the market right now," O'Sullivan told AN. "But I know the people were expecting something from us, expecting certain drive characteristics and performance, and I didn't want to disappoint them." While O'Sullivan's defense of the diesel Mazda is admirable, the exec stops short of giving us an indication of when the new engine will finally arrive.

Will the new Mazda Miata be available with multiple engines?

At this point, the countdown until the launch of the all-new, fourth-generation 2016 Mazda MX-5 Miata can be measured in hours until its September 3 unveiling as easily as it can in days. With the debut of such a highly anticipated model so close, the rumors about the new sports car are starting to boil over.
We recently heard that the new Miata would likely get a 2.0-liter Skyactiv four-cylinder with a six-speed manual, plus a decent drop in weight compared to the current gen. There's even the rumored possibility of a fastback coupe version sometime in the future.
Now, Australia's GoAuto is adding another dollop of speculation into the mix with the claim that there could be "potentially more engine options," according to Mazda Australia managing director Martin Benders to the website. The more potent option would still be the 2.0-liter Skyactiv with a power bump from its current 167 hp to closer to 200 ponies. The other possible powerplant option would be a 1.5-liter, naturally aspirated four-cylinder taken from the upcoming Mazda2 replacement. This version would also ditch some of the MX-5's more premium features to cut the weight and the price slightly.

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.
