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.

Crossovers help Mazda post its best January sales in 24 years

Mazda's 2017 ended on a bit of a flat note. It wrapped up the year with 2.8 percent fewer U.S. sales than 2016, and 8 of the 12 months lower month-over-month. But 2018 is off to a much brighter start with the company having its best January sales month since 1994, with just under 25,000 cars sold. Besides that headline statistic, the higher sales also mean this January exceeded 2017's sales by 15 percent or about 3,300 cars and put it ahead of January in that healthy 2016 year. Compared with this past December, though, sales are down about 2,000 cars. The gains are entirely due to the success of Mazda's crossover SUVs. The CX-5 was the best of the best with a month-over-month gain of over 66 percent. In actual numbers it sold about 13,500 copies compared with about 8,000 last January. The big three-row CX-9 had a big jump going from 1,600 units sold last January to about 2,300 for a gain of almost 47 percent. Even the little CX-3 saw a small gain between the two Januarys, going from about 1,200 to 1,350 sales. View 14 Photos Mazda's January would've been even better if its conventional cars hadn't dropped so much. Both Mazda Miata and Mazda6 sales dropped by just over half. The Mazda dropped from 3,300 sales to just under 1,600, and the Miata dropped from a little over 900 to a little over 400. Mazda3 held on a little better with just a 12 percent drop from last January going from about 6,600 to 5,800 sales. The lopsidedness of these sales isn't all that surprising. Crossovers have been a boon to loads of manufacturers. For example, Mitsubishi had an 2017 full of sales improvements, with the company finally breaking 100,000 units for the first time in years, and it was all because of improving crossover sales. January's sales also continue an unfortunate downward trend for Mazda's cars, with both the Mazda6 and Mazda3 having month-over-month declines every single month since February. It will be interesting to see if the new turbocharged engine option on the Mazda6 will improve sales of the sedan later this year. Related Video: This content is hosted by a third party.

Mazda Skyactiv-X Review | The revolution begins with a squeeze-bang

The matte black Skyactiv-X prototype looks like a rough Mazda3, perhaps reconstructed after a bad wreck by an over-enthusiastic owner of a spot welder and lots of gaffers' tape. Ribbed ducts poke out of the dash sending two breaths of conditioned air to no one in particular. Even its revolutionary engine, the thing we're here to experience, is entombed in a massive, nondescript cover to mask its unseemly noises. It's a wild, strange way to meet a very unconventional vehicle that promises diesel-like fuel economy, a wide torque band, and an exotic method for burning less gas than ever before. It takes a few hours for Mazda's engineers to explain the fundamental principles of operation. For more detail, read our Skyactiv-X Spark Controlled Compression Ignition explainer, but here's a very brief overview. Skyactiv-X marries some traditional gasoline engine characteristics with a novel form of compression ignition called SPCCI. The key for Skyactiv-X is to use very high compression in the cylinder and an extremely lean fuel-air mixture. Squeezed right to the cusp of getting hot enough to blow up all on its own (which is very hard to predict), a squirt of extra gas and a spark interject to cross that compression-ignition threshold in a controlled and predictable manner. See the animation below: That takes a few essential components to get just right. One is a massive amount of computer processing power and some pressure sensors in the individual cylinders, because the ambient conditions change how and when these things happen. Skyactiv-X uses a clutched supercharger to pump in additional air when needed to nail the mixture precisely, and high-pressure injectors to get the low ratios of fuel to disperse properly in the chamber. And since it operates like a conventional gasoline engine sometimes, it uses valve timing to lower the very high compression ratio so it doesn't reach combustion ignition in that mode. In practice, the Skyactiv-X runs in compression ignition mode most of the time. In practical terms, that means it drives like a torquey gasoline Skyactiv engine. The torque curve is broad and flat — diesel-like in that respect. That also means it can get away with using a six-speed transmission and a lower final drive for better response. There's enough grunt and economy together that Mazda can let the engine spin faster — at 60 mph, it's running at roughly 1,000 more RPM than a similar gas engine, with greater efficiency.
