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.

2015 Chevrolet Corvette Z06 [w/videos]

I think I was supposed to be back hours ago. Driving northwest on State Road 190 with a final destination deep in the heart of the Death Valley National Park, it occurs to me that I might have agreed to return after an hour or so, instead of the four I'll end up stealing, solo, in the new Z06. Somewhere in the combination of mountain vistas, arching, speed-hungry desert roads, and the sound of this titanic engine on a constant run up the rev ladder, I forgot everything I'd promised back at home base. The generous, civilized part of me worries for a moment that absconding with the new-best Corvette might have left one of my fellow journalists without a car. But the selfish part of me – the part largely in control of the rocket-launcher of a throttle under my right foot ­– says "screw it." I spent two days with the 2015 Chevy Corvette Z06, a monster of a sports car that will soon be dominating track days everywhere, and I never once was inclined to share it. Hurtling through the shattered stillness of the desert and pulling big Gs at Spring Mountain circuit, I never felt overly disposed to give up my seat. This Corvette, more than any I've yet driven, was deep enough to hold my attention; for two days, for two years, probably. With this Z06, the Corvette steps over the amazing-for-the-price category, and solidly into the best-cars-in-the-world zone. There are peripheral elements that remind me of its blue collar, Bowtie heritage, sure, but there's more that simply begs me to carry on driving... faster. Most casual car observers will be able to pick the 2015 Z06 out from its less aggressive Stingray brothers. Subtler hints include a new, more open grille, larger extractor on the taller hood and rather discreet badges on the flanks of the car. More outrageous is the finned spoiler on the rear trunk lid, and the widebody look offered from flared fenders – an extra 1.57 inches (40 millimeters) at their beefiest point. Even driving around performance-car-laden Pahrump, NV – loaded thanks to the very active community at the Spring Mountain racing resort – members of the local populace were turning heads, waving and generally noting the Z06 with approval when I drove through town. In Torch Red over black painted aluminum wheels, staggered at 19-inches in front and 20 at the back, the amped-up Z06 hits a new level of road presence for the C7.

Recharge Wrap-Up: LAPD gets Zero MMX, Chevy's new inverter, Hyundai Tucson's new powertrains

Some police in Los Angeles will be riding Zero MMX electric motorcycles on duty. The LAPD is adding the fully electric police/military all-terrain bikes to its patrol fleet. According to Officer Steve Carbajal of the department's off-road unit, "It costs less than 50 cents to charge compared to using gallons of gas, maintenance is simple, and the community appreciates how quiet they are." The electric bikes, with their lack of noise and a headlight the rider can turn off, also have the benefit of stealth, giving the officers what Carbajal calls "an added tactical advantage." The MMX also has swappable batteries, is designed for quick ignition and has power reserve capabilities so the rider won't be caught with a dead battery while chasing down a perp.

Drivers of classic cars in Detroit were able to fill up their tanks at gas prices corresponding to their model year, thanks to a promotion by Hagerty Insurance for National Collector Car Appreciation Day on July 11. That meant prices from 21 to 90 cents a gallon, as the cars that showed up ranged from the years 1929 to 1989. That's about as affordable as charging your EV. Head over to Autoweek for more details and some photos from the event. The next-generation Chevrolet Volt will likely benefit from a new inverter being developed by General Motors. GM is about two-thirds of the way through the development of the new inverter, which should be ready in January 2016. The inverter, which has a peak output of 55 kilowatts a continuous output of 33 kilowatts, will be adaptable for use in other GM vehicles. Chevrolet is working to reduce the Volt's production costs by $10,000 per vehicle, which should make it more affordable, and the new inverter could help reach that goal should it make its way into the car.

"We are covering the waterfront on all alternative fuel strategies, from standard hybrid, to plug-in, battery-electric, and fuel cell," says Hyundai's US Chief Dave Zuchowski.
