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.

Nissan heading to Le Mans with 1,250-hp GT-R LM Nismo [w/videos]

Endurance racing faced a pivotal year in 2012. The FIA and the ACO had just come together to form the new World Endurance Championship when Peugeot announced it was shuttering its team, leaving only one manufacturer to contest the top LMP1 class of the nascent series. Fortunately Toyota was able to advance its program to join Audi in the WEC and at the 24 Hours of Le Mans. Two seasons later Porsche joined the fight, and now Nissan has formally announced its return to Le Mans as well. Revealed in Nissan's With Dad spot during the Super Bowl, the Japanese automaker is set to join the grid with the innovative GT-R LM Nismo you see here. It's a hybrid just like the challengers from Audi, Porsche and Toyota, but instead of a mid-engine/rear-drive setup, Nissan's oddball challenger places its engine in the front, driving the front wheels. The 3.0-liter twin-turbocharged V6 is mated to a five-speed sequential gearbox and produces upwards of 550 horsepower on its own, but is mated to an electric Energy Recovery System that kicks in over 700 additional horses for a combined hybrid output exceeding 1,250 hp. That could make Nissan's the most powerful LMP1 on the grid, while still complying with the fuel flow limits outlined in the rulebook that gives participating constructors the latitude to toy with different configurations. Both powertrain components are mounted under the long nose of the oddly styled prototype, behind the canopy of the rearward cockpit that may give it a similar profile to the DeltaWing prototype and subsequent ZEOD RC. But the unconventional GT-R LM Nismo is also innovative in its own way. The front-drive configuration means that the Nissan prototype actually has wider tires up front than in the back, and also allowed for a drastically different approach to aerodynamics. Instead of testing it out at a handful of events in its first season, with the GT-R LM, Nissan will contest the full 2015 FIA World Endurance Championship, starting with the 6 Hours of Silverstone in April and including the 24 Hours of Le Mans in June.

Recharge Wrap-up: Nikola One to debut in December, UK charging to outnumber gas stations by 2020

Nikola Motor Company plans to unveil its Nikola One electric truck prototype on December 2, 2016. The company, based in Salt Lake City, says it has "engineered the holy grail of the trucking industry," according to founder and CEO Trevor Milton. "We are not aware of any zero emission truck in the world that can haul 80,000 pounds more than 1,000 miles and do it without stopping. The Nikola One requires only 15 minutes of downtime before heading out for the next 1,000 miles." Nikola also has plans to build emissions-free power plants. Read more in the press release from Nikola, or at the company website. Nissan says EV charging stations will outnumber gas stations in the UK by 2020. The UK had just 8,472 gas stations at the end of 2015, down from 37,539 in 1970. Extrapolating that to 2020, the UK is expected to be home to fewer than 7,870 fuel stations. By then, and possibly much sooner, charging stations are expected to surpass 7,900, up from 4,100 in 2016. Growing interest in EVs, infrastructure expansion, and better batteries mean that "the tipping point for mass EV uptake is upon us," according to Nissan EV Manager Edward Jones.

In a partnership with EVgo, BMW i3 and i8 customers will have the option of an annual or pay-as-you-go ChargeNow membership with service in cities around the country, with "introductory pricing" available until July 31, 2017. For those i3 owners in California already enrolled in the DC fast charging program, their free access is expiring.
