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.

2020 Mazda3 hatchback starts at $24,620, a $100 increase

Car and Driver got the scoop on some 2020 Mazda3 pricing, and anyone waiting for the new model year had better bring more money. The Mazda3 sedan goes up by $500 to $21,500. After the $920 destination charge, that's a total of $22,420. On the sedan, however, the extra dosh pays for extra equipment. Every sedan trim gets Mazda's i-Activsense driver assistance tech, meaning adaptive cruise control, automatic emergency braking, blind-spot monitoring, lane-keep assist, and lane-departure warning. The i-Activsense suite had been an option the sedan's entry-level trims. The Mazda3 sedan in Select guise, one step above the entry-level model, increases $100 to $23,620. Starting price for the front-wheel drive 2020-model-year hatchback comes in at $24,620 after destination. C/D says that's a $1,020 bump, but we believe that figure is an error. Based on the fact that Mazda's U.S. pricing rounds off to the nearest hundred and destination is $920, it seems more likely the $24,620 price includes destination. In that case, the 2020 Mazda3 hatch only goes up by $100. The five-door models don't get any more equipment, but Mazda say's there's a new finish for the wheels on the top-tier Premium trim. All other trims hold steady. The 2.5-liter four-cylinder with a square 186 horsepower and 186 pound-feet of torque remains the sole engine option, a six-speed automatic is the standard transmission on all trims, the hatchback in Premium form offering a six-speed manual option. Buyers of the entry-level sedan are stuck with front-wheel drive, while every other trim offers all-wheel drive for $1,400. The sedans should hit dealerships this month, and the hatchbacks will roll in come September.
