Next Mazdaspeed3 could go naturally aspirated?

The new Mazda3 is a stunner, both aesthetically and from a driving perspective. As with all good things, though, there's always room for improvement. That's where the wizards from Mazdaspeed come in. Mazda's in-house tuner has been tweaking and turbocharging the five-door Mazda3 since 2007, with impressive results.
We've shown you renderings of what the third-generation Mazdaspeed3 could look like, and for the most part your response was quite positive. Now, AutoExpress has come out with details of just what might be under that long hood. According to our friends across the pond, the new Mazda3 MPS (that's what the Speed3 is called in Her Majesty's auto industry) will be arriving with a new, high-revving, naturally aspirated engine. Wait, what?
Yes, if the rumors are to be believed, the next Mazdaspeed3 will ditch its turbocharger. According to an anonymous engineer, the new MS3 will arrive in December (this is for the UK market, mind you) with a 200-horsepower, naturally aspirated engine. The 2.0-liter mill is based on the Skyactiv engine in the new 3, and should be capable of a sub-seven-second run to 62 miles per hour.

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.

Living Life Large: Driving $2 million worth of cars in one week

Monterey Car Week has quickly become one of my favorite events of the year. There's something for everyone – classic car shows, modern concepts and new vehicle debuts, auctions, racing, and so much more. From a media perspective, there's also a chance to drive a ton of cars. Many automakers bring their latest wares out to Monterey for us to test during our limited free time, and it's a great opportunity to experience fantastic metal against a gorgeous backdrop. That's exactly what I did this year. Instead of flying into Monterey and being driven around, my journey started in Los Angeles and ended in Napa, and I managed to get behind the wheel of some $2 million worth of new cars. Some were old favorites, and many were new experiences. But looking back, this was one of the best weeks of driving I've had in years. Rather than try to come up with some common arc to tie these cars together, here are my notes on all the cars I tested in California earlier this month, presented in the order in which they were driven. 2016 Mazda CX-3 The CX-3 pictured here isn't the exact one I drove in California, but it's close. The only difference was color – my delivered-to-LAX tester wore Mazda's awesome new Ceramic hue (pictured below on the MX-5 Miata). I used the CX-3 to slum through crummy Los Angeles traffic for two hours on the way out to Santa Barbara, with a quick stop at In-N-Out Burger on the way for good measure. A lot nicer inside than I remember. Everyone praises Mazda for its excellence in engineering and design, but there's a lot to be said for the improvements in overall interior refinement. Quiet, comfortable, and well-equipped; the CX-3 made sitting on the 405 freeway a lot more pleasant. Not all that functional. I had a hard time fitting a week's worth of luggage for two people inside. The cargo area and rear passenger compartment were filled, with only enough room on top to see out the back window. A Honda HR-V would've swallowed all that luggage with plenty of room for more. So good to drive. Not surprising, since this wasn't my first time in the CX-3. I knew this CUV would be good on twisty roads, but on the highway it's really exceptional. Road and wind noise are minimal and the overall ride quality is a comfortable sort of sporty. This is definitely something I could drive every day – it's enjoyable during commuting and entertaining on more interesting roads.
