2016 Mazda MX-5 Miata first engine shot revealed

We've dug deep for just about every scrap of 2016 Mazda MX-5 Miata info available out of the car's California reveal celebration, but powertrain particulars have been especially hard to come by. While we still don't have engine specifications, the folks over at Autoweek have scored a nice scoop - the first underhood photos of one of the display cars.
In the image above, the ND-generation Miata is clearly shown to be powered by a Skyactiv inline four-cylinder, as expected, but its displacement remains unclear. The engine is most likely either the 2.0-liter Skyactiv-G engine offered in low-end Mazda3 and CX-5 models or the 2.5-liter Skyactiv-G found in those same vehicles' upper trims. In those iterations, the 2.0-liter generates 155 horsepower and 154 pound-feet of torque, while the larger-displacement engine nets out at 184 hp and 185 lb-ft. There is no sign of a turbocharger, a feature rumored to be fitted to at least one test mule. There has also been previous rumors of a 1.5-liter Skyactiv engine, possibly for overseas markets.
The 2.0-liter strikes us as the most likely scenario, particularly as Mazda has worked diligently to save every gram in the new car, dropping a pledged 100 kilograms (220 pounds) over the current model, even while adding content. It's entirely possible that the alleged turbo car was, in fact, a mule for the Miata's Alfa Romeo sister car, which is expected to have a wholly different powertrain. Or it could simply be a second engine option for an eventual Mazdaspeed variant, perhaps.

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.

2019 Mazda CX-5 fuel economy takes a hit with new turbocharged engine

We learned all about the 2019 Mazda CX-5 last week, and now we've discovered fuel economy for its new 2.5-liter turbocharged engine. Unsurprisingly, it gets slightly worse fuel economy than its naturally aspirated counterpart. The 2019 turbo crossover, which only comes in all-wheel drive form, gets 22 mpg city and 27 mpg on the highway. Front-wheel drive CX-5s with the naturally aspirated 2.5 liter net you 25 mpg city and 31 mpg highway — all-wheel drive drops 1 mpg in both categories. For a little comparison, the turbocharged engine makes 250 horsepower and 310 pound-feet of torque on 93 octane gasoline, while the non-boosted engine makes 187 horsepower and 186 pound-feet of torque. You're definitely taking a hit in fuel economy, but the gain in power might be worth it, since the decrease isn't that terrible. Cars in its price and power range with all-wheel drive have comparable fuel economy. The Ford Escape with the 2.0-liter turbo is rated at 20/27; Chevrolet's Equinox with the 2.0-liter turbo is 22/28 and the VW Tiguan gets 21/29. There isn't really a clear winner in fuel economy for this much power when you look around the segment, but Mazda's engine is half a liter larger than everyone else. This translates to better torque than most of its competitors, but Mazda manages similar fuel economy. Also similar to many of these decked-out compact crossovers is the new high price of the Mazda we wrote about before. You won't be getting in to the turbocharged CX-5 for any less than $35,865. If you wanted a bigger Mazda like the CX-9, its fuel economy figures aren't significantly worse than the CX-5. Front-wheel drive versions are rated 22/28, and it drops 2 mpg in each category for all-wheel drive. The updated 2019 CX-5 should be coming to dealers soon.
