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.

Mazda6 Coupe coming along with more Mazdaspeed models?

The predecessor to the Mazda6, the Mazda 626, was sold in a multitude of body styles across the globe. It could, of course, be had as a sedan, but a two-door coupe, known stateside as the MX-6, was also available on the same platform. Now, a new report from Motor Trend claims that a two-door version of the modern Mazda6 could be on the way.
This would be remarkable for a number of reasons, as automakers have been abandoning this type of non-luxury coupe for decades. A class that counted entries from Toyota, Nissan, Chevrolet, Dodge and Chrysler is now occupied solely by Honda with its Accord Coupe.
Ignoring that, though, MT claims we'll see a two-door Mazda6 in the second half of 2016. When that new variant arrives, it will be with an even more dramatic version of the sedan's Kodo design language. Mazda could rely even more heavily on styling inspiration of the Shinari Concept, which already informs the design of the current 6 sedan, when the two-door model arrives.

Mazda's mission for the 2017 CX-5: Smooth out the NVH

NVH: the dreaded noise, vibration, and harshness. According to current Mazda CX-5 owners, as well as those who decided against becoming owners, NVH was its biggest area of need. Traveling in the CX-5 was just too loud, so Mazda's engineers made sure that the redesigned, second-generation model would offer its occupants a more serene environment in keeping with quieter competitors. To reduce wind noise, more aerodynamic parts were strategically placed about the exterior, while extra efforts were made to reduce low-frequency noises on coarse surfaces. According to Mazda engineer Dave Coleman, the new CX-5 is nearly as quiet as its platform-mate, the 2016 CX-9. Actually, to be very accurate, all Mazdas apart from the CX-3 and 2 (aka Toyota iA) now share that platform. Another reason compact SUV buyers opted to skip the CX-5 was its comparatively firm ride. So, while the CX-5 remains "head and shoulders above the segment for handling," according to Coleman, the ride was improved. One of the primary ways of achieving that was the adoption of rigid steering mounts, which allowed for the suspension to be less stiff without a loss in handling precision.

Under the hood, every CX-5 now comes standard with the 2.5-liter Skyactiv-G four-cylinder, with output figures to be announced at a later date. The 2.0-liter, previously standard on the Sport trim, has been exiled to other markets. However, finally making its appearance on these shores is Mazda's 2.2-liter Skyactiv-D diesel engine. Although Mazda did its darndest to make it certifiable in the United States without a urea injection system, it was ultimately unable to do so without resorting to an ultra-sluggish throttle response that engineers deemed was anathema to what was expected of a Mazda. Therefore, the diesel-powered CX-5 will indeed have a DEF tank that will need to be periodically topped off to not run afoul of emissions regulations. Otherwise, the 2017 CX-5 is very much an evolution of the SUV it replaces. Customers thought its size was just right, so its passenger and cargo area remain in the same ballpark.
