Mazda concept probably previews the next Mazda3 at the Tokyo show

This year's Tokyo Motor Show is shaping up to be an interesting one, with a Nismo Leaf, Mitsubishi e-Evolution concept, and a pair of interesting Toyota concepts already lined up. Now Mazda is joining with its own big reveal of two concepts. One is a design concept that will give us an idea of where the company is heading, and another is all but guaranteed to be our first look at the new Mazda3. There are a few reasons we say that one of these concepts has to be the next Mazda3. One is the fact that Mazda says it's a concept planned for production. The company also describes it as "a compact hatchback that fuses next-generation technology and design," and it uses the new Skyactiv-X spark-controlled compression ignition engine and "Skyactiv-Vehicle Architecture." Plus, just looking at the teasers, the design is a clear evolution of the current Mazda3 hatchback. It looks as though the hood and roofline curve a bit more, and some of the sharp creases of the current car have been smoothed out. The other concept Mazda is bringing to the Tokyo Motor Show seems to be just that, a concept. Mazda says it's just a design concept meant to exhibit how other Mazdas will look. Apparently it's a continuation of the company's current "Kodo" design language. Based on the teaser image, the car appears to be a sedan and consists mainly of clean, elegant curves, with hardly a crease anywhere except the edge of the trunk. The elegant lines are reminiscent of the RX-Vision concept, just with a couple extra doors and a different color. Mazda will have a couple of other new vehicles on display in Tokyo as well. The company will show the Japan-only CX-8 three-row crossover and a special-edition Roadster (Miata) Red Top edition. We presume it's a Miata with a red soft top. Stay tuned for more details from the full reveal. Related Video:

Mazdaspeed2 supermini hot hatch under consideration

Though the Ford Fiesta ST and Fiat 500 Abarth (and arguably the Mini Cooper S) may stand pretty much alone in the North American market, in overseas markets, supermini hot hatches are a big deal. Unfortunately, challengers like the Volkswagen Polo GTI, Seat Ibiza Cupra and Renault Clio RS 200 Turbo never make it to our showrooms, but word has it that there's soon to be a new entry on the market.
That would be the Mazdaspeed2, which would be badged in certain markets as the Mazda2 MPS. Speaking with Australian site CarAdvice.com.au at the launch of the Mazda2 on which it would be based, the Japanese automaker's global sales chief and the hatchback's deputy product manager hinted that such a product is definitely being discussed, even if it hasn't yet been approved.
This wouldn't be the first time such a notion were entertained, as Mazda has shown numerous performance concepts based on the previous Mazda2/Demio over the years, but none have come to fruition.

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.
