Mazda Miata could get retractable hardtop in New York

The upcoming New York Auto Show just got a little more exciting because Mazda could debut the latest MX-5 Miata with a power retractable hardtop there. The best evidence comes from Autocar, which has an image of Mazda's invitation. The message promises a "world premiere" in the Big Apple and further teases, "Help us blow the lid off the New York Auto Show." The last Miata PRHT made up 52 percent of the roadster's sales mix in the US, so creating another one is an easy decision for the company. According to Autocar, expect the new roof mechanism to be lighter and more compact than the previous design. It would still add some weight compared to the cloth top, but customers would get the added insulation and security from the hardtop. With the NC PRHT as a guide, don't expect many changes for the new other than the roof. The 2.0-liter four-cylinder with 155 horsepower and 148 pound-feet of torque with either the six-speed manual or automatic should still make for an exciting drive. The hardtop just makes life a little more comfortable if you have to deal with rain or snow for part of the year. We can't wait to see it. Related Video:

The Mazda MX-5 Miata is truly a four-season sports car

For all intents and purposes, the Mazda MX-5 Miata is a product of California. I know it says Hiroshima on the shipping container, but the car belongs to the Golden State as it was dreamt up in Irvine and honed its driving skills on the roads near Santa Barbara. And logic would dictate the Miata would be useless in any situation other than direct sunlight. That's what drivers from other states would think, anyway. It's the time of year when those of us from the west coast fly out to places where it's snowy and icy and everyone laughs at us because the cold and white stuff essentially shuts us down. Make fun of Californians driving in the rain or freaking out when the outside temperature dips below 55 degrees. What can we say, we're just out of our element. Perhaps, then, it's surprising the Miata handles snow a lot better than I do. I found this out when Mazda sent me to Crested Butte, CO, for a little fun on a frozen track. Yes, there was a lot of sideways action, but it had more to do with the two California residents inside than with the car. The company really invited journalists to Colorado to get an idea of how its all-wheel-drive crossovers perform when things get snowy and icy. But the real show was watching how we navigated the autocross course they set up for the rear-drive Miatas that Mazda brought along. The Miata had a good heater, but it was my laughter caused by immense admiration that kept me from freezing my fingers off. Armed with a set of Bridgestone Blizzak winter tires, the Miata performs just about how you'd expect it to – if you're light on the gas and quick with the steering and have a good amount of patience in you. It all works well if you're a pro driver, less so if you're not a frequent track visitor, regardless of the weather. But fortunately we were using the fourth-generation Miata, which has to be the most forgiving sports car ever. On pavement, it behaves like a compact hatchback. Put it in sixth and it's relaxed and compliant, with a ride that doesn't beat you up and an engine that knows when you just want to get where you need to go. Provoke it, however, and it rewards you with predictable responses from the controls. It does the same thing on ice, if you have a firm grasp on how a car responds to the frozen stuff. Starts are tricky, even in second gear, if you underestimate the power from the 2.0-liter four.

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.
