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.

Hyundai plots a Nissan Juke fighter

A few years ago, Hyundai Motor America CEO Dave Zuchowski suggested interest in taking on the Nissan Juke with a subcompact crossover. It looks like that project is coming together, as we caught Hyundai testing a small, curiously-styled SUV in Germany recently. The SUV is expected to share a lot of the same chassis components as the i20, a hatchback that's sold in other parts of the world, with the same engine lineup as the new i30, another hatchback that Hyundai doesn't sell in the America. In the United Kingdom, the i30 is available with engines including a 1.4-liter gasoline and a 1.6-liter diesel unit. Front-wheel drive would be standard with all-wheel drive an option. The heavily-camouflaged prototype doesn't give away a lot of the SUV's design. The front of the vehicle is hidden away, but what we can see the grille features hexagonal shapes instead of the horizontal bars that we've become accustomed to seeing in Hyundais. The headlights mimic the Jeep Cherokee's design with thin slits on top and larger, round units toward the bottom. At the back, camouflage hides the majority of the prototype, but the taillights appear to be different than the rest of Hyundai's offerings. The outline of the taillights resembles the same units found on the Intrado Concept, indicating the vehicle will get some design cues from the hydrogen-powered prototype. A single exhaust outlet protrudes underneath the rear end. The overall profile of the SUV appears to be smaller than the Tucson, which is currently Hyundai's smallest crossover in the US.

Recharge Wrap-up: Custom Nissan Leaf video, Shell's Arctic oil plans

A video shows a customized Nissan Leaf. An owner in Japan slapped a pretty spiffy body kit on his EV, along with some Forgiato custom wheels and brakes. There's no telling what effects these modifications have on the car's aerodynamics or driving range, but it definitely gives the leaf a unique and sporty look. Check it out in the video above, and read more at Ecomento. Shell has big plans to drill for oil in the Arctic Ocean. With 13 percent of the world's undiscovered oil resting beneath those frigid waters, the company sees this new frontier as promising, despite the challenges involved in exploiting it. So far, Shell has spent $7 billion on Arctic operations without having extracted any oil yet. Of course, the idea of Arctic drilling has loads of opposition from concerned individual and organizations concerned with the environmental hazards of extracting oil in the icy north. Read in-depth about Shell's plans at Bloomberg. Ford has won the Altair Enlighten Award for its lightweight technology in the F-150. The award program honors automotive innovations in weight reduction. Ford was recognized for shaving 700 pounds off of the F-150 while improving performance and safety. "It's encouraging to see Ford implementing a holistic lightweighting strategy, which resulted in impressive weight savings that were incredibly significant to the judging panel," says Altair's Vice President of Global Automotive, Dave Mason. General Motors was the runner-up, with its weight savings in the Cadillac ATS and CTS. Read more at PitchEngine. The Diesel Technology Forum has outlined environmental improvements in heavy-duty vehicles at a rulemaking hearing in front of the EPA and NHTSA. Between 2010 and 2014, clean diesel technology reduced carbon emissions equal to that of 2.4 coal-fired power plants, and NOx emissions equal to 158 coal plants. New rules would help further improve the environmental performance of diesel engines. "Advances in diesel engine technology will continue to contribute to the overall efficiency gains of vehicles under this proposed rule," says Diesel Technology Forum Executive Director Allen Schaeffer. "As a result we expect diesel technology to remain the primary power-plant for commercial trucks into the foreseeable future." Read more in the press release below.
