2016 Mazda CX-9 caught on video

We already know from earlier spy shots that the second-generation Mazda CX-9 is advancing in development, but here's an opportunity to actually see the crossover on the road. The video shows the CX-9's rear, but wait 50 seconds for a good look at it in profile and from the front. The CX-9 is no longer wearing the same camouflage from the last spy photos, but this time it has more cladding to hide the lines. Even with the obfuscation, you can still get a sense of the general shape. The CUV largely looks like a stretched version of the CX-5, which is a great place to start. Rumors suggest the new CX-9 will debut in November at the 2015 Los Angeles Auto Show and to launch in 2016 for the 2017 model year. Power is tipped to come from a turbocharged, 2.5-liter Skyactiv four-cylinder, and all-wheel drive is expected to be available. Related Video:

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.

2014 Mazda6: Winter's End Update

The Winter Without End is seemingly dead. Outside my office windows, my brown and yellow lawn is fully exposed to the increasingly powerful sunshine, the morning birdsong is louder than anything until the garbage trucks start rolling, and I'm seriously considering having the summer tires put back on my personal fleet. That last one is a little scary, as I'm a firm believer in the April Snow Jinx, but you get the idea.
The long-term Mazda6 has also long since left my driveway. Looking back on my notes from the time it was in my charge, however, I see all remarks are dominated by one highlighted section at the top: "worst winter drive of all time." I hardly need the reminder, to be honest. Here's what happened.
When the Mazda showed up at my door, we'd already fitted the thing with its new winter rubber: Bridgestone Blizzaks. Plunking down for dedicated snow tires was a near necessity this year - as it almost always is in Michigan. We didn't see much reprieve from snow-choked, iced over roads here in Ann Arbor, and the knobbier rubber proved invaluable in getting me out of my house time and again.
