Mazda Miata 'fathers' Hall and Case offer a tour through the roadster's history

The original Mazda Miata broke onto the automotive scene in 1989 and was a huge success. However, the convertible's genesis goes all the way back to the early '80s. Bob Hall and Dean Case were among the inside men of the program on the US side, and they were on hand at Mazda Raceway Laguna Seca during the recent MX-5 event there to tell some of their stories about the project's beginning.
Hall was on the Miata project from very early on, and one of his most fascinating stories is how the convertible got its shape. The droptop wasn't necessarily going to be a rear-wheel drive roadster. There were both front-wheel-drive coupe and mid-engine concepts being considered. In fact, the classic look of the NA generation was the least favorite of the three at the sketch stage.
Hall comes off as a jokester hiding a genius mind. He has a fountain of information in his head about what a Miata should be, but it all comes down to "less is more." However, he admits that it's easy to conceive that idea, but it's much harder to actually execute it well.

Feds investigating Mazda CX-9 over suspension problems

The National Highway Traffic Safety Administration is opening a preliminary evaluation into the 2007-2008 Mazda CX-9 because the lower ball joint in the front suspension can potentially separate while driving. An estimated 54,000 examples of the crossover might be affected. The investigation was prompted by six complaints of this happening on the road. Because the complaints are coming more rapidly as of late, NHTSA thinks the issue could be getting worse. The problem also appears to be more prevalent in states that use salt on their roads in the winter. None of the failures caused any injuries, and all but one happened at 20 miles per hour or slower. NHTSA's preliminary evaluations "assess the scope, frequency, and safety consequence" of a potential problem and can sometimes lead to recalls.

SUMMARY: The Office of Defects Investigation (ODI) has received six (6) complaints (VOQs) alleging incidents of front suspension LBJ separation in MY 2007 through 2008 Mazda CX-9 vehicles. The reports appear to show an increasing trend. One of the separations allegedly occurred at 40 mph and the other 5 incidents occurred at speeds between 0 and 20 mph. The first VOQ was received in October 2013, followed by 2 reports in late 2014 and 3 reports in the first 5 months of 2015. Four of the VOQs are from states using high volumes of road salts (?salt states?) which, for purposes of this investigation, include: Connecticut, District of Columbia, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, and Wisconsin. The other VOQs were from northern Virginia, which borders the ?salt state? region, and South Carolina. ODI also identified EWR field report data related to the alleged defect in the subject vehicles. A preliminary investigation is being opened to assess the scope, frequency, and safety consequence of the alleged defect. The six VOQs associated with this investigation are: 10717510, 10714469, 10695142, 10668978, 10640541, and 10546535.

Mazda still really wants to bring diesels to America

Mazda's Skyactiv program has delivered much of what it promised for the brand's latest crop of products, namely great fuel economy and excellent driving dynamics. However, the Skyactiv diesel engine has yet to reach our shores. It's been promised ever since the new Mazda6 showed up here for the 2014 model year. According to a new report from Automotive News, Mazda's CEO Masamichi Kogai said that the Mazda Skyactiv D diesel powertrain is still set to make an American appearance. He told Automotive News that there is an internal timeline to get it to the States, and while he didn't reveal the timeline, he said he wants it to come here before he steps down as CEO. The powertrain is offered elsewhere, so it fits in the company's current vehicles, but the US has specific regulatory hurdles, and the engine's extra cost has to make sense from a sales and volume perspective. We doubt VW's diesel scandal helped the engine's sales pitch, either. Automotive News also reports that the next generation of Skyactiv designs and engines are also on their way and will advance and improve on the current generation's strengths. Engineers revealed to Automotive News that they expect a 30 percent improvement in efficiency and are developing an engine with the sky-high compression ratio of 18:1. This impressive ratio could be a further indication of Mazda's pursuit of homogenous charge compression ignition (HCCI) engines. Mazda has had plenty of success with its strategy of making very efficient internal-combustion engines, but there are some concerns that the company can only improve so much. The main worry comes from the company's lack of investment in hybrid and electric powertrains. Even Mazda's North American CEO Masahiro Moro expressed concern about meeting a 54.5 mpg mandate for 2025. That mandate will no longer take effect, but increasing fuel economy requirements will always be an issue. Related Video:
