2015 Nissan Micra

Several years ago, poutine started showing up on the menus of a number of Detroit-area restaurants. For those unfamiliar with the Canadian specialty, it involves serving up french fries, gravy and cheese curds all in one artery-clogging heap. It's not really my thing, but the comfort-food dish has caught hold here in The D, and many absolutely swear by it. In a country where we happily serve Double Down sandwiches, and where competitive eating qualifies as sport, it's hard to believe le poutine isn't spreading like wildfire.
Given Detroit's proximity to Canada, it's not surprising that this culinary creation has managed to find its way across the border. The same thing goes for cars - we Detroiters are routinely privy to lots of Great White North imports. No, we can't buy not-for-US vehicles like the Nissan X-Trail, Mercedes-Benz B-Class (at least, the gasoline version), or now-discontinued products like the Honda Civic-based Acura CSX or EL before it. But Ontario-plated examples of these cars can be seen all the time here in southeast Michigan - it's a far more common occurrence than you might think.
These days, it's rare that an automaker will introduce a model to Canada without offering it up in the United States - especially a car that stands to do big things for a company's presence in North America. But with this 2015 Nissan Micra, that's exactly what's happened; Nissan's US arm has repeatedly stated that there are no plans to offer the car in Yankeeland. Why is the Micra so important? This five-door hatchback enters Canada with the coveted title of being the most affordable new car in the country: just $9,998 Canadian (CAD) to start. In fact, the Micra launches to our north just as the larger, four-door Versa Sedan is phased out in Canada - a vehicle that holds the lowest-cost title here in the US, at $11,990 USD.

Watch Nissan's autonomous Leaf in action

Getting its semi-autonomous Leaf legalized in Japan was just the first step. Now, Nissan is giving demonstrations of what its fully autonomous car is capable of at this year's Combined Exhibition of Advanced Technologies (CEATEC) show - Japan's equivalent to America's Consumer Electronics Show. To show off the possibilities of its technologies, Nissan had an oval track set up at the show giving rides in an autonomous Leaf to the media. Even Nissan CEO Carlos Ghosn and Toyota CEO Akio Toyodo caught a ride.
Nissan has since released a couple videos of its CEATEC demos, with one designed to look like a news report. In this video, you can watch the car go around the track and navigate intersections and road hazards. The second video shows Ghosn riding in the car, and he hints that Nissan's goal of having an autonomous vehicle in production by 2020 might be more of a worst-case scenario. Watch both videos and read through Nissan's official press release below.

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.
