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.

Mazda MX-5 Miata goes Head 2 Head with Subaru BRZ

It's a battle that's been in the making for some time now: the Subaru BRZ versus the Mazda MX-5 Miata. And now that the new Miata has arrived – and in Club spec to boot – that's exactly what Motor Trend has lined up for its latest episode of Head 2 Head. Now before you go screaming that one's a coupe and the other a convertible, take a few commonalities into account. Roofs aside, both feature a 2.0-liter four mounted up front, driving the rear wheels through a six-speed manual transmission. Both are made by Japanese automakers and cost around $25-30k, give or take. Both produce around the same amount of torque, and while the Subaru may be more powerful, the Mazda's considerably lighter. To create a more even contest, then, you'd have to line a BRZ up against a Scion FR-S, or the MX-5 against the upcoming Fiat version of the same. Of course, being that close on paper doesn't mean that it's a draw. One has to come out on top. And after taking both along country roads and the Streets of Willow racing circuit, our friends at MT have picked one over the other. You'll want to watch the 22-minute video above (or at least skip ahead to the end) to see which came out on top, but if you're as enthused by a purist driver's car as we are, you'll enjoy every minute of it.

This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.
