Mazda recalls 193k CX-9 crossovers over corroded suspension

An issue with the suspension on the CX-9 has prompted Mazda and the National Highway Traffic Safety Administration to recall 193,484 vehicles across the United States. The campaign specifically affects units from the 2007-2014 model years, manufactured between October 24, 2006, and December 28, 2013. In those affected vehicles, the ball joints in the front suspension may corrode due to water leaking into the fitting. According to the statement below, if the ball joint rusts, the front lower control arm could separate, resulting in a loss of steering control. And needless to say, that could lead to a crash. To repair the issue, Mazda will have to replace both the left and right lower control arms, and will naturally do so free of charge, but will undertake the repairs in stages. First, owners of the affected vehicles will receive a notification that a recall campaign is under way. Then they'll get a second letter when the parts are ready and they can bring their vehicles into their local dealers. The company will start first with 2007-09 vehicles, specifically those registered in the snowy states of the Northeast and Midwest. Specifically: Connecticut, Delaware, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin, and Washington, DC. (Oddly, states in the the western portion of the Midwest, as well as the Rocky Mountains and the Pacific Northwest, were not included in that initial phase. Nor was Alaska, for that matter.) After that they'll call in 2010-14 models in the same states before undertaking repairs on vehicles in other areas to the west and south.

The affected vehicles have front suspension ball joints that may corrode from water leaking into the fitting. CONSEQUENCE: Over time, the ball joint corrosion may result in the front lower control arm separating from the ball joint, causing a loss of steering control and increasing the risk of a crash.

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.

Mazda patents show rotary engine for range-extended EV

Two years ago, Mazda introduced a fascinating range-extended electric car called the Mazda2 RE Range-Extender. It took an electric Mazda2, and dropped in an itty-bitty 330cc rotary engine. It wasn't the rotary-powered sports car we had hoped for, but it seemed like a unique way to keep the quirky engine alive and kicking. But not long after the car's reveal, it seemed to disappear. Now the basic idea has resurfaced with a few modern updates in a couple of US patents. The first patent is pretty straightforward and describes a range-extended EV similar to the BMW i3. At the front is an electric motor driving the front wheels. At the back is an internal combustion engine that powers an electric generator. In the middle is a lithium-ion battery for storing and delivering electricity. It's the same set-up as that Mazda2. The second patent is for an engine start-and-stop system, but specifically for rotary engines. The system is designed to shut off a rotary engine when not needed, much as modern piston engines do. It also stops the rotor in a position that closes the intake port to ensure no fuel or exhaust emissions slip out through the intake tract. This is necessary since there are no valves in a rotary, and air and exhaust come through ports that are "opened" and "closed" by the rotor itself. The patent also describes the possibility of firing a spark plug after the fuel has been cut to eliminate any leftover fuel emissions. This system would theoretically improve a rotary engine's fuel economy and emissions significantly, which would be a boon as those are two of the rotary's major weaknesses. The rotary-engine patent also includes the same range-extended powertrain drawing as the first patent. It's there as a description of a possible application. And in such an application, where the rotary wouldn't have to run all the time, the system could take advantage of the rotary's inherent strengths. Weight can be kept low thanks to the engine's small dimensions, which should help in keeping the car sprightly and efficient. Rotaries are renowned for smoothness, too, so it shouldn't need too much refining and sound deadening, the latter of which adds more weight. The small size would also help with packaging, leaving more space for people, cargo, or possibly batteries. And since it has been patented, the company may be looking to bring the system to market.
