Mazda files patent applications for inline-six technology, new transmission

We've known for some time that Mazda is one of the OEMs getting back on the inline-six engine bandwagon, and a report from Japan gives us a glimpse of some of the automaker's plans. Mazda has filed patent applications for both new exhaust components (depicted with an inline-six) and a new eight-speed automatic transmission.  The news comes from a blog called T's Media (fire up Google Translate), which located the new hardware in two separate fillings, one for exhaust system components and one for the new transmission.  Mazda's lineup has been exclusively powered by four-cylinder engines since the demise of the last-generation CX-9, which utilized a 3.7-liter V6 sourced from Ford. Since, Mazda has relied on turbocharging to get more power out of its SkyActiv four-pots, but changes may be coming. Prior reports have indicated that Mazda wants a new, larger engine architecture to power vehicles built on a new, larger platform. This new chassis is expected to accommodate longitudinal, rear-wheel drive powertrains, which could spawn larger crossovers and SUVs. It could also potentially underpin a new rear-wheel drive coupe, if Mazda decides to go that route.  While the inline engine itself is not news, what we're seeing here might actually be hints as to Mazda's approach to the next generation of its SkyActiv engine architecture. Mazda's exhaust patent seems to describe a scalable — perhaps even modular — setup intended to be used with inline and potentially even V-engines.  "Provided is an engine exhaust structure capable of securing exhaust efficiency while reducing the size of the engine by changing the structure of an exhaust port," a translation of the patent application's introduction says. "[T]here has been proposed a technique for collecting exhaust gas discharged from each cylinder inside a cylinder head without using a separate exhaust manifold with the aim of downsizing the engine." In other words, Mazda is looking for ways to make its future engines more compact, and the strategy detailed here is the use of an integrated exhaust manifold, similar to what other automakers (such as Honda and Ford) have utilized on their smaller-displacement turbocharged engines. The sketch above of an inline-six engine with just two exhaust ports illustrates this concept.  The eight-speed transmission, while noteworthy in its own right as Mazda currently relies on aging six-speeds, doesn't seem to offer us anything particularly game-changing.  Related Video:

Mazda recalls 2019-2020 Mazda3 for errant activation of emergency braking system

The newly redesigned Mazda3 has been subject to numerous recalls since it went on sale for the 2019 model year. Today brings news of another such occurrence, as Mazda recalls 35,390 2019-2020 Mazda3s (sedans and hatchbacks). This recall is related to the automatic emergency braking system equipped to certain models. According to Mazda, affected vehicles may “unexpectedly stop while driving due to inadvertent activation of the Smart Braking System automatic emergency braking system.” The programming of the systemÂ’s software could cause the Mazda3 to “falsely detect an obstacle in front of the vehicle while driving.” In response to that detection, the software may automatically apply the brakes despite no collision being imminent. We donÂ’t have to explain how dangerous that could end up being for the driver and those around them. Your car slamming on the brakes for no reason could easily be the cause of an accident. As of now, Mazda says no injuries or deaths have been reported as a result of the defect. In case you havenÂ’t experienced the system in your Mazda3 yet, there is something to look out for. Mazda says a warning alarm will sound and a warning message will appear in the instrument cluster and head-up display when the car is about to perform an emergency stop. Mazda said that itÂ’s reported the defect to the NHTSA, but it hasnÂ’t been posted on the website yet. The fix is easy for some, but more difficult for others. Vehicles with early build dates will need the whole instrument cluster replaced or reprogrammed, as these cars have a different procedure for "temporary manual deactivation of the Smart Braking System." These early build cars will also receive a new owner's manual to reflect the revised procedure of temporary manual deactivation of the system. Later cars will only need the Smart Braking System software reprogrammed with an improved version. Mailings to owners for notification purposes should be completed on or before February 17 next year.

Mazda2 production fires up in Mexico

Mazda has officially kicked off production of the next-generation Mazda2 at the company's new factory in Salamanca, Mexico. Alongside the auto assembly plant, operations have also commenced at the facility's engine machining factory.
"With the start of production of the all-new Mazda2, operations underway at the engine machining plant, and an increase in our annual production capacity, we now have an even stronger production framework capable of supplying global markets with Skyactiv products of the same high quality level as those made in Japan," Mazda de Mexico Vehicle Operation's President Keishi Egawa said in a statement. "At the same time, we are pleased to be able to make a contribution to Mexico's further economic growth."
MMVO joins Mazda's Hofu Plant in Japan and the Auto Alliance factory in Thailand, which commenced Mazda2 production in July and September, respectively.
