Mazda's awesome Hiroshima museum now navigable by Google Maps

Visiting an auto museum is one of the best ways we know to connect with car culture and to commune with the past and bone up on one's knowledge. Most of us have a decent museum within a few hours drive of where we live, but that doesn't mean it's easy to see the world's great collections - factors like cost, time and mobility can get in the way. Videos are great, but they don't allow us to browse at our own pace or choose what we'd like to focus on. The folks behind Google Maps have a solution - the virtual museum tour, as seen here at Mazda's fantastic museum in Hiroshima, Japan.
The Google Maps tour allows viewers to take a walk through the main exhibition area of the museum, and you can focus on specific classic cars from Mazda, or check out displays featuring new technologies like Skyactiv. To take a quick spin through the museum - or a leisurely stroll at your own pace - scroll down to start your own virtual tour.

Mazda6 diesel delayed until April

Diesel enthusiasts waiting on the new Skyactiv-D-powered Mazda6 will have to wait a bit longer. The shapely fuel-efficient four-door has just had its North American launch pushed back to April, due to delays in emissions testing. Mazda had originally planned to launch the Mazda6 diesel before the end of this year, making the four- to five-month delay a rather serious one.
Mazda's senior vice president of US operations, Robert Davis, told Mazda employees in a letter obtained by Automotive News that, "final certification testing - the results of which are looking encouraging - is taking longer than we had initially expected." Following this letter, Mazda made an official announcement:
"The on-sale date for Mazda6 SKYACTIV-D clean-diesel has been moved to late-Spring 2014, to accommodate final emissions testing and certification. We are pleased with the ongoing development and are excited to launch this much-anticipated vehicle in North America. 2014 Mazda6 sales continue to exceed both our expectations and our production abilities, and supplies of the car are short at dealers across the U.S. More information on the SKYACTIV-D clean diesel Mazda6 will be available closer to the on-sale date."

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:
