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:

2018 Mazda MX-5 Miata and MX-5 Miata RF pricing announced

At Chicago, Mazda has announced official 2018 pricing for the MX-5 Miata, both soft-top and RF. The trick-roofed RF version, or Retractable Fastback, has a coupe-like power hardtop that opens up into a targa. It's only natural that there are MX-5 models on display at the Chicago Auto Show, as 29 years earlier the original Miata was unveiled there. All ND generation cars sold in the U.S. have the 155-horsepower Skyactiv-G engine with a choice of six-speed manual or six-speed automatic. While the canvas-topped 2018 MX-5 starts from $25,295 as a manual Sport, the RF bypasses the Sport spec and starts directly from the Club, which for the RF means a $31,910 starting price, or $355 more than for 2017; the soft-top 2018 Club costs $29,555 in comparison, or a measly $120 hike. The manual Club has a limited slip differential, a front strut brace and Bilstein suspension. Similarly to the soft-top car, the RF also gets a Brembo/BBS brake/wheel/appearance package that hikes the price to $35,680 — and that is only available with manual transmission. That package costs $32,925 for the soft-top, which has also a $700 Recaro sport seating option for the aforementioned Brembo/BBS package, but that is unavailable for the RF. Grand Touring comes with automatic climate control, heated leather seats and adaptive lighting, at a price of $30,195 for the soft top and $32,750 for the RF. Add new-for-2018 Nappa leather for the Grand Touring for $300. At launch in the 2017 model year, the RF Grand Touring was priced $3,000 dearer than a comparable soft-top version, but that difference has now shrunk by $500.

The Miata is always the answer, but which one is the answer for you?

If you follow along with our long-term vehicles, you know that we had a 2016 Miata Club in the fleet. It's a Miata that had every sporty bit available installed, but there are other ways to spec out an MX-5. Just recently, we had the chance to sample the other end of the MX-5 spectrum, the Miata RF Grand Touring. While they're cut from the same sheetmetal, they're surprisingly different cars. So we thought we'd put together a little guide to help you figure out what bodystyle and trim level of Miata is right for you. How do you like the wind in your hair? If you're someone who loves soaking up the sun and having the wind blow through your hair, or lack thereof, there's no replacement for the soft-top Miata. The manual folding mechanism will get you out into the fresh air faster than virtually any other convertible, and it will go back up just as easily when the rain comes. Raising and lowering it is quick and easy, and can be done with one hand from the driver's seat. And with the top down, you'll be greeted by breeze from virtually every direction, and an airy, unencumbered feeling that only comes with a full convertible. However, if you prefer to keep your hair in place and just get some sun, the RF is the better choice. The retractable targa top still descends and reemerges quickly, taking just 13 seconds either way. Keeping the windows up with the targa stowed will allow in plenty of sun, but will keep wind to a minimum. But when the windows drop, you'll still get a healthy dose of airflow. It still doesn't feel as open as the soft top, though, since you'll be able to catch the fastback pillar out of the corner of your eye. But if you value protection over airflow, that won't be an issue. View 11 Photos Does your Miata need to be a daily driver and occasional road tripper? While many Miatas will be weekend toys, one of the appealing things about them is that they're reliable enough and have just enough cargo space that they can serve as an everyday vehicle. For people who want to use a Miata as a daily commuter, and even take it on road trips, we would recommend an RF with the Grand Touring trim, as seen above. Although it still isn't a quiet car in the grand scheme of things, the RF's solid top makes it more livable for highway stints both short and long. The Grand Touring trim comes recommended for these purposes for a couple of reasons. Foremost is the more forgiving suspension shared between it and the base-level Sport.
