Mazda creates reproduction parts program for North American MX-5 Miata

In 2017 Mazda announced a restoration program for the MX-5 Miata in Japan. The good news was that owners of Miatas that looked like they'd been thoroughly enjoyed for decades could get their convertibles returned to as-new condition. The bad news is that the program was a trial for "quality verification," and only open to the Japanese market. At the time, Mazda Japan said it was "considering re-supply of parts that became discontinued" for the first-gen NA series produced from 1989 to 1997. In February this year, the carmaker's then-CEO revealed that "Our fans can be reassured that additional parts, identified by owners and specialty shops, will become available by June of this year." The time has come, Mazda North America announcing a reproduction parts program for first-gen Miatas with a catalog of more than 1,100 new and legacy components.  The automaker says it spoke to Miata clubs and shops to determine which parts were needed most. Among this first salvo will be a fabric soft top using the same rear screen material from the NA series, roller mechanism for the side windows, brake calipers, and a set of aluminum Enkei wheels in the original design that are lighter and boast a better finish. Perhaps even better are the arcane OEM parts that can be desperately hard to source for era-appropriate restorations, like grommets, bolts, gas shocks and the "Roadster" badge that's an eBay go-to (called a "Mascot" on the parts list). Each piece has been redeveloped to take advantage of modern materials and build techniques while maintaining the look of the period-correct original.  The parts list PDF runs to 42 pages. Anyone with a TLC-starved Miata in the garage, the love your jinba ittai droptop has been waiting for is here.   

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.

2014 Mazda6: June 2013

The 2014 Mazda6 is our most recent addition to the Autoblog long-term fleet, and we spent the month of June getting to know our Soul Red tester, generally enjoying the honeymoon phase of this twelve-month relationship. During June, the Mazda6 spent the majority of its time with director of photography Drew Phillips, who in addition to putting together this pretty gallery of our rakish long-term car, had a lot to say about it as a daily driver.
You see, not too long before Mazda delivered our long-term 6, Drew bought a 2014 CX-5 crossover to support his growing family. The CX-5 was the first vehicle to use Mazda's full suite of Skyactiv technologies, and we've generally enjoyed the good-to-drive CUV. A lot of that CX-5 goodness lies beneath the more shapely lines of this sleek Mazda6 sedan, so it's only fitting that Drew had a lot of comparisons between Mazda's two housemates during his month behind the wheel.
