10 automakers shack up in Detroit hotel to talk Takata airbags

Since Takata has decided not to take the lead concerning potential issues with its airbag inflators, the automakers have. Perhaps that's unsurprising, since it's the automakers, not Takata, that will take a beating on the dealership floor if consumers decide its models are a health hazards. The Detroit News reports that Toyota, Honda, General Motors, Ford, Chrysler, Mazda, BMW, Nissan, Mitsubishi and Subaru met in a hotel conference room near the Detroit Metropolitan Airport last week to sort out a way to understand the technical issues involved. So far, faulty airbag inflators have been ruled the cause of five deaths and 50 injuries around the world, but neither Takata nor investigators understands exactly why the inflators are malfunctioning. The National Highway Traffic Safety Administration recently asked Takata to issue a national recall, Takata declined, citing a minuscule failure rate and the fact that it's still investigating the issue. Toyota and Honda then made an industry-wide appeal for "a coordinated, comprehensive testing program" that would pinpoint the problem inflators and get them replaced, and that's what the Detroit meeting was about. Numerous issues, however, will make this a long row to hoe: simply getting the parts to replace the nearly 20 million inflators in cars recalled around the world so far - even working with other suppliers - will take a years, but more importantly, no one knows if the replacement inflators currently being installed will suffer the same issue. Answers will hopefully come quickly with Takata, the ten automakers and NHTSA all independently investigating the problem.

2016 Mazda CX-5 recalled to address failing DRLs

Mazda announced Tuesday that it will recall more than 35,000 examples of the 2016 CX-5 crossover to address an issue that may lead to deterioration or failure of its LED daytime running lights.  In affected models, the gasket used to seal the wiring harness to the LED module was not manufactured to Mazda's specification. As it degrades over time, it can release sulfur, which in turn can potentially corrode the LED control circuit, causing the LEDs themselves to flicker, illuminate poorly or even fail outright.  Per Mazda, there is no alert for this condition, so drivers can potentially lose daytime running light function without realizing it, leaving them tougher to spot in poor light.  The campaign will cover 36,761 CX-5s sold in the U.S. and U.S. territories. Mazda says no accidents or injuries related to the issue have so far been reported.  This new campaign has not yet been published in the National Highway Transportation Safety Administration (NHTSA) recall database, and Mazda's statement did not include details of the proper remedy for the issue or when customers can expect to be contacted to arrange for service.  We expect that all 2016 CX-5s with LED DRLs will receive new harness gaskets and that those showing signs of LED module corrosion will have those replaced as well.  The 2016 CX-5 has been the subject of four other recall campaigns — including one for an improperly torqued steering knuckle bolt and another for a defective fuel filler pipe — but this is the first  new campaign for that model year since 2016.  Related Video: This content is hosted by a third party.

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.
