NHTSA urges owners of recalled Takata airbag vehicles to take immediate action

The National Highway Traffic Safety Administration and the Department of Transportation are taking the unusual step of issuing a followup press release urging owners of certain recalled vehicles "to act immediately" to fix their cars and trucks. The problem in question concerns the repair campaigns for rupturing Takata airbag inflators issued in June and covers a long list of models from Toyota, Lexus, Honda, Acura, Mazda, BMW, Nissan, Infiniti, Buick, Cadillac, Chevrolet, GMC, Oldsmobile and Pontiac.
While NHSTA doesn't specifically say why the recall is vital in the new release, Toyota's own explanation in its newly announced renotification campaign earlier today sheds some new light on the topic. According to the Japanese automaker, in testing, Takata found a possible link between the rupturing airbag inflators and high humidity. NHTSA is advocating that all owners pursue repairs immediately if they haven't already done so already. This is especially crucial for those drivers especially in Florida, Puerto Rico, Guam, Saipan, American Samoa, Virgin Islands and Hawaii because of the humid conditions there.
We don't need to tell you how dangerous an inadvertent airbag deployment could be - even in a stationary vehicle - but adding to the Takata issue is fears that the deployment could lead to shrapnel being sprayed into the cabin.

2016 Mazda MX-5 Miata Club Edition sharpens, styles the new roadster

One could argue that any iteration of the last-generation Mazda MX-5 Miata was worth having. But were it our money on the line, we'd have likely driven home with the Club, a simple trim that, for a reasonable $28,665 (for the retractable hardtop model), added a number of performance and aesthetic features. The 2016 MX-5 Miata Club Edition should prove to be a successful followup. Like last year's model, it adds a limited-slip differential, a retuned suspension with Bilstein shocks and a tower brace under the hood. On the aesthetic side of the game, 17-inch gunmetal wheels are included, along with a new rear spoiler and a front splitter. For those that demand an even sharper Club Edition, though, Mazda will also offer even lighter wheels, courtesy of BBS, along with Brembo brakes and the aero kit from the MX-5 Global Cup racer.

Lighter, smaller, quicker and more nimble than its predecessor, MX-5 has adopted Mazda's full suite of SKYACTIV Technology and KODO-Soul of Motion design. In the process, MX-5 has shed approximately 150 pounds from its predecessor, with a curb weight of 2,332 lbs. when equipped with SKYACTIV-MT six-speed manual transmission (2,381 lbs. with the six-speed automatic transmission). The MX-5 Club heightens performance with trim-level exclusive: - 17-inch gunmetal alloy wheels wrapped in 205/45R17 tires - Limited-slip differential when equipped with SKYACTIV-MT - Bilstein shocks when equipped with SKYACTIV-MT - Shock tower brace when equipped with SKYACTIV-MT - Front air dam and rear lip spoilers Standard equipment on MX-5 Club models includes MAZDA CONNECTTM infotainment system with a seven-inch color touchscreen display and multi-function commander control, HD and SiriusXM Satellite Radio, two USB ports, piano black side mirrors and seatback bars and a nine-speaker Bose audio system with headrest speakers.

Mazda files patents for a sequential twin-turbo setup

Mazda has a history of interesting engine technologies, from yesterday's rotary engine to tomorrow's compression ignition engine, and new patents show it still may have some internal combustion tricks up its sleeve. The one on display in these patents isn't especially new in concept, though. A sequential twin-turbocharger setup is something Mazda itself used on the third-generation RX-7. But it's something we haven't seen much of lately. It looks like it could have some possible advantages over older sequential systems, and it has some potential advantages for enthusiasts. First a quick and dirty primer for what makes a sequential twin-turbo system distinct from other twin-turbo systems. In many twin-turbo engines, there are simply two turbos that work together as one bigger turbo. They're the same size, and they spool up at the same time. With a sequential setup, at low rpm, a smaller turbocharger is spooled up first at low-rpm for quicker throttle response, and as the rpm and exhaust pressure increases, a valve opens up that allows a larger turbocharger to also spool up and provide high-rpm boost. That's basically how the Mazda design shown above functions. A big flap blocks off the larger turbocharger exhaust inlet, channeling all the exhaust to the smaller turbo. When more exhaust is available at high rpm, it looks like that flap opens up to spool up the big turbo, too. What's interesting here is that the way the turbochargers are packaged takes up less space than past systems. It looks like both turbos are contained in one unit that shares the same exhaust outlet, meaning the exhaust manifold could be kept simple and compact. In fact, the piping for compressed intake air could also be shared, reducing the amount of piping, which would further decrease the amount of materials and possible failure points. There are a number advantages of making this system smaller. The potential applications of the system are much greater, since it could fit in smaller cars with smaller engine bays. Making the system smaller also means that there won't be as much weight, which is important from both fuel economy and performance standpoints. Finally, the smaller setup likely uses fewer materials, which could make the system cheaper and thus easier to offer on a wider range of vehicles, or at least more profitable for Mazda.
