Mazda, Mitsubishi, and Subaru expand global Takata recalls by 715k [UPDATE]

UPDATE: Subaru of America spokesperson Michael McHale tells Autoblog that the company is recalling 78,000 Imprezas from the 2004 and 2005 model years in the US. This is a national expansion of the company's previous regional recall for the Impreza. The Takata airbag inflator recall just keeps growing. The latest expansion encompasses 715,000 vehicles from Mazda, Mitsubishi, and Subaru. Many of the affected models are in Japan. The largest expansion from these three automakers comes from Mitsubishi. According to Reuters, the company is adding 100,000 vehicles in Japan and 412,000 outside of the country without identifying any specific regions. Mazda is issuing safety campaigns for 112,000 vehicles in Japan, and some of these include models that the company produces there for Mitsubishi and Nissan, according to Reuters. In statement to Autoblog (embedded below), Mazda said that it is still evaluating the situation in terms of a possible effect on the US. Finally, Subaru is calling in 91,000 Imprezas in Japan. At this time, it isn't clear whether Mitsubishi's or Subaru's expansions affect the United States, but Autoblog has reached out to them for more information. According to research by the National Highway Traffic Safety Administration, exposure to moisture can cause the propellant in these inflators to ignite too quickly and cause these dangerous ruptures. Takata has also been investigating the problem. Related Video: Mazda statement "We are aware of the NHTSA/Takata announcement, and are evaluating the effects of it on Mazda. As soon as we have had a chance to fully evaluate the situation – number of vehicles affected, age of those vehicles, where they're located, etc. – we will be able to share those details."

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.

2016 Mazda MX-5 Miata Club long-term wrap-up | Farewell, fun friend

About one year ago, we took delivery of a 2016 Mazda MX-5 Miata. We made sure we got the sportiest version we could, the Club model (which includes Bilstein shocks, a limited-slip differential and a front shock tower brace) with optional BBS wheels and Brembo brakes. We also sprung for the appearance package to give our cute little roadster a modicum of aggression. It was a tad pricey at $32,835, but we enjoyed every minute of it. Well, almost every minute of it. It's not a perfect car, as it's loud and stiff on the highway, and we ran into an issue in which the top had to be replaced (under warranty). But minor grievances aside, just about everyone who drove the little roadster came back with a smile, especially when we took it to a racetrack. Below are final thoughts on the car from our editors. Senior Green Editor John Beltz Snyder: This car is about as car as any car gets. It's so car! That is to say, it's pure in its mission and in its effective execution as a driver's plaything. Its crisp steering, snickety six-speed manual gearbox, and rev-happy engine create the wonderful sensation that you're driving faster than the speedometer reads. Normal speeds never felt so heroic. The view out the front is fantastic, too, and the curves of the hood are nothing short of inspiring as they frame the road ahead. I don't care that it's noisy, jarring, and ergonomically weird. Old and British in spirit, it offers a level of engagement that's hard to find in a new car, especially for under $30,000. Anyone who has a Miata in their stable isn't lucky. They're smart. Senior Editor Alex Kierstein: I'm a bit embarrassed to think back to my first impressions about driving the MX-5 now that I've had so much seat time in this one. While I loved the idea of it as a throwback to the original NA Miata from the moment it was revealed, I was a bit turned off by how civilized it was. And how quick it was. No longer a momentum car, the new MX-5 seemed more forgiving of bad gear selection or a bad corner entry. I felt like something had been removed, a ragged edge, some everyday engagement. Well, a year on, and my feelings have changed. If you stop comparing it directly to the (slow, weedy, rattly, uncomfortable) first- and second-generation cars, it's a brilliant little roadster. I miss the raw edge less and enjoy the livability more — the raw edge was really just a lack of civility. A flaw that forced you to engage with the thing every moment.
