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 ad showing Facebook updates while driving criticized by Senate committee [w/video]

Senate Commerce Committee Chairman Jay Rockefeller, D-WV, held an all-day summit on Thursday to discuss the dangers of using modern technology while driving, during which an ad that Mazda aired during the Super Bowl was used as an example of the worrisome future towards which we're headed. While seemingly innocuous at first glance, the ad, which can be seen below, shows a brief glimpse of a driver using the Mazda Connect infotainment system in a Mazda3 to check/update his Facebook page while driving down the road.
Officials from major communications companies like Samsung, Google and Apple attended the summit, as well as representatives from automakers including General Motors and Toyota. A representative from Mazda was not present despite the company's own currently available technology being used as the poster child for the issues being discussed.
According to Automotive News, Senator Rockefeller warned the automaker and communication execs on hand that he will propose legislation to regulate the use of technology while driving if they don't work together to implement their own standards more quickly. Michael Robinson, GM's vice president of sustainability and global regulatory affairs, argued that his company has had distracted driving guidelines in place for 15 years since the advent of its OnStar system, noting that the technology in question has also helped the automaker save lives through automatic crash detection and calls to 911.

Mazda's Tokyo concepts have us wishing for more Mazdaspeed

It's been a while since we've seen any new Mazdaspeed machinery, and we're sorry to report that today isn't the day the wait ends. But if you want to see what they might look like based on Mazda's latest models, the Tokyo Auto Salon will be the place to be in a couple of weeks. Turns out the Zoom-Zoom brand has a whole raft of performance models in store for the aftermarket expo. Most intriguing to our eyes is the trio of Racing concepts – one based on the MX-5 Miata roadster, one on the CX-3 crossover, and one on the Mazda6 sedan. Each is done up in black with full aero kit, new rolling stock, and Alcantara interior. An adjustable suspension is the big change to the MX-5 – known simply as the Mazda Roadster in Japan – which also features red trim. As does the CX-3, while the Atenza (which we know as the Mazda6) goes for a more monochromatic, murdered-out appearance. The rally-prepped Mazda2 (known domestically as the Demio) focuses on a stripped-out interior with bucket seats, racing harnesses and a roll cage. There's a spec racing MX-5 in white livery with roll cage and tow hooks as well to join the Global Cup roadster we've already seen. That also goes for the RX-Vision and LM55 Vision Grand Turismo concepts which have already made the rounds but will be on display at the Tokyo salon as well. But it's those three Racing concepts that leave us salivating for production performance models to come – and hopefully come to North America in the process. Related Video:
