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 reveals 25th anniversary edition MX-5 Miata alongside next-gen chassis

Ford may be celebrating the 50th anniversary of the Mustang this week, but it's not the only automaker with a sports car icon to fete at this year's New York Auto Show. Mazda is also celebrating the 25th anniversary of the MX-5 Miata with an array of 15 classic models. It's also showing off the chassis for the next MX-5, and unveiling a special 25th Anniversary Edition.
The special edition is based on the retractable hardtop model with either manual or automatic transmission, Bilstein shocks, a metallic red paint job with contrasting black roof and an off-white leather interior. Naturally, special badging can be found inside and out to set it apart from the record 940,000 other MX-5s sold to date, and just 100 examples will find their way to US buyers.
Along with the two-tone special, Mazda is also showing off the new Skyactiv chassis and engine that'll underpin and power the upcoming next-generation MX-5 (as well as an as-yet-to-be-determined Fiat Group roadster if the two parties can work out their differences). With a lower center of gravity that's also closer to the middle of the car, the new chassis promises even better balance and a good couple hundred pounds of weight savings over the outgoing model. Check it all out in the press releases below.

Flyin' Miata's 525-hp V8-powered ND finally hits the streets

Flyin' Miata, in its valiant quest to turn Mazda's roadsters into small, Japanese Corvettes, has finally finished its first V8-powered ND Miata. The company has been slowly teasing us with images and videos for months, but it wasn't until this week that the car finally made it to the streets. As soon as the current ND generation Miata was released, Flyin' Miata started the work to shoehorn a GM LS3 under the hood. The company has a history of building brutish, V8-powered Miatas. It sells everything from minor parts to full V8 conversion kits. For those with the cash that prefer to avoid the hassle, Flyin' Miata will sell you a complete, turn-key car. The price hasn't been finalized, but customers should expect to pay about $50,000 plus the cost of the MX-5. The new car has a worked-over LS3 that sends 525 horsepower to the rear wheels through a Tremec T56 transmission. Flyin' Miata says the rear differential comes from a V8 Camaro. Other new bits include exhaust, suspension, brakes, and a roll cage. Flyin' Miata tells us that the V8-swapped ND will weigh 2,592 lbs, a little more than 200 lbs more than the porkiest stock Miata. Despite twice as many cylinders and more than three times the displacement of the stock four banger, the LS3 V8 is a relatively small and lightweight engine. The finished car has a 53:47 front to rear weight distribution. Final touches are being finished, but cars and kits should be available soon. This article has been updated with some info straight from Flyin' Miata. Thanks, Keith! Related Video: News Source: Road & Track, Flyin' Miata Mazda Convertible Performance flyin miata
