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:

Race-inspired Mazda 3, CX-5, and Miata look great with white letter tires

At the 2020 Tokyo Auto Salon, a customization show that is kind of like SEMA but definitely not the same, manufacturers promote what is available and explore what's possible. Mazda brought a variety of vehicles to the show, but none more intriguing than the Mazda Motorsports Miata, Mazda3, and CX-5 concepts. The trio has race-inspired graphics, as well as a slew of visual and mechanical changes. The three vehicles have a core pack of changes, then each one has its own signature pieces to create some differentiation. The roadster, hatchback, and crossover have height-adjustable suspensions, upgraded brakes, MazdaSpeed tow hooks, circular number body decals, new wheel nuts, Alcantara steering wheels and shift knobs, special heel plates, MazdaSpeed six-point harnesses, and MazdaSpeed sport seats. The Miata and 3 have Fujitsubo stainless mufflers, while the CX-5 has a slightly different exhaust. The Roadster appropriately has the most involved individual upgrades. It has a body kit with front, side, and rear alterations, and it sits on RAYS ZE40 17x7.5J wheels wrapped in Potenza RE-71R 215 / 45R17 rubber with beautiful white lettering. It also has a Cusco roll bar, a MazdaSpeed rear spoiler, a MazdaSpeed strut bar, and a MazdaSpeed lower arm bar. Inside, the door trim, decoration panel, shift boot, center console lid, and parking brake boot are draped in Alcantara. An aluminum pedal set is adds a final touch of polish. On the Mazda 3 hatchback, the aero kit is specifically noted to be "Signature Style." Mazda also upgraded the strut bar and lower arm bar, and threw on Rays ZE40 18x7.5J wheels in Potenza RE-71R 215 / 45R18 tires, also with white lettering. Black mirror caps, a scuff plate, and a sports pedal set complete the concept. On the CX-5, Mazda made it sportier but also added some crossover-focused features, too.. It has Mazda-styled aero, an Auto Exe sports muffler Rays G25EDGE F1 20x8.5J wheels, Bridgestone ALENZA001 255 / 45R20 tires with white lettering, and a new wheel nut set. It also has a scuff plate, premium floor mats, a premium luggage mat, and sports pedals. For now, these are only concepts, with no word as to whether anything similar could hit Japanese markets, let alone U.S. shores. A Mazda engineer previously said a MazdaSpeed3 wouldn't happen, but the company is reportedly considering a 3 with a 250-horsepower 2.5-liter four-cylinder engine.  Related Video: This content is hosted by a third party.
