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:

Massive Airbag Recall Affects Seven Automakers

The recall of faulty airbag inflators supplied by Takata has exploded today to grow to seven automakers. In most cases, only models in certain high-humidity regions were affected because the National Highway Traffic Safety Administration found in its investigation that moisture played a role in determining whether there would be a problem. However, some companies opted for national campaigns. The exact number of affected models for these campaigns isn't yet known at this time. BMW is recalling an undisclosed number of 325i, 325Xi, 330i and 330Xi models from the 2001 through 2005 model years and the 2001-2006 model year versions of the 325Ci and 330Ci for the driver side and passenger side inflators. Only vehicles currently registered in Florida, Puerto Rico, Hawaii and the US Virgin Islands are covered under this recall. Neither Chrysler's filing with NHTSA nor its press release list the specific models affected, but a company spokesperson told Autoblog that at this time it only covers the driver and passenger side inflators for the 2006 Dodge Charger in Florida, Puerto Rico, Hawaii and the US Virgin Islands In most cases, only models in certain high-humidity regions were affected because the NHTSA found that moisture played a roll in determining if there would be a problem. Ford is recalling an estimated 58,669 cars that include the 2005-2006 model years of the Ford GT for the driver and passenger inflators, the 2007-2007 model years of the Mustang for the driver side and 2004 Ranger for the passenger side. It covers vehicles originally sold or currently registered in, wait for it... Florida, Puerto Rico, Hawaii and the US Virgin Islands. Honda is issuing three separate recalls regarding the problem. First, the company is recalling the 2002-2003 model years Civic, CR-V and Odyssey and the 2003 model year of the Accord, Element, Pilot and Acura MDX to replace the passenger's side inflator. This covers all models nationwide. Second, Honda is repairing the passenger's side airbag inflator in the 2003-2005 Accord, Civic, CR-V, Element, Pilot, the 2003-2004 model year versions of the Odyssey, the 2003-2005 model year Acura MDX and 2005 Acura RL. However, only for vehicles located in Alabama, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico and the US Virgin Islands. Owners will be notified in July. Finally, Honda is separately replacing some models' driver's side inflators.

2019 Mazda CX-5 turbo model seemingly confirmed, doesn't come cheap

We reported last month on some leaked documents that announced the 2019 Mazda CX-5 would get the turbocharged 2.5-liter four-cylinder as an option, and it's looking even more official now that additional documents have appeared on Reddit. The new information comes from a "Product Information Bulletin" that not only confirms the engine's availability but reveals pricing, trims and feature sets for the new model year. As it turns out, the turbo CX-5 won't be cheap. The base price for a CX-5 with that engine will be $35,865 with destination. That's about $5,500 more than the cheapest turbocharged Mazda6. There are a couple of reasons for this. The turbo engine will only be available on two new high-end trims for the CX-5, Grand Touring Reserve and Signature. Both of those trims bring a variety of high-end features and options with them. It can also only be paired with all-wheel drive. The Mazda6 turbo engine is available on the slightly lower Grand Touring trim and is only paired to a front-drive drivetrain. Conspicuously absent from the 2019 documentation though is the elusive Skyactiv-D diesel engine. This is strange, since the engine has been rated by the EPA, so it's presumably ready for introduction to the U.S. market. We'll be curious to learn that engine's fate. We could see the turbo gas engine threatening the diesel's U.S. introduction, since it delivers the same amount of torque as the diesel with more horsepower. Plus the diesel didn't get amazing EPA numbers. But that's just speculation on our part, and it's entirely possible the diesel will still come here. The rest of the CX-5 lineup sees some welcome upgrades, too. The infotainment on CX-5s starting with the second-lowest Touring model will get standard Apple CarPlay and Android Auto compatibility. All models also will receive G-Vectoring Plus. The feature, along with the turbo engine option, was announced for the Japanese CX-5 recently. What this system adds is a little bit of braking force to the outside wheel as the driver winds the wheel back to a straight position when exiting a corner or completing a lane-change. The idea is that it helps make the car more stable when straightening out after a turn. Also, although the turbo CX-5 models will be rather pricey, the other CX-5 models won't change much in price. The base Sport trim starts at $200 more than the 2018, the Touring model increases just $100, and the Grand Touring goes up by $400.
