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.

Recharge Wrap-up: Renovo Coupe at CES, Aussies tour US in Tesla Model S

Australians review the Tesla Model S in a Seattle to LA road trip video. The folks from CarAdvice drive the P85+ along the West Coast of the US, testing out the car, trying the Superchargers, stopping by some notable sites along the way and even making use of roadside assistance. While the video shows what it's like to take the Tesla on a US road trip, it gives viewers Down Under a glimpse of their own future. Tesla just began sales in a country that, while on the other side of the globe, also features long distances between cities and a new Supercharger network. Check out the video below or read more at Inside EVs. A UK taxi company is introducing the Nissan e-NV200 to its fleet. C&C Taxi, which has been using six Nissan Leafs in its Cornwall taxi service since early December, has added the passenger-ready e-NV200 Combi to its stable of cabs. Mark Richards, manager of C&C's fleet, is happy with its performance and money saved after over 1,000 miles of service so far, and plans to replace the rest of the diesel fleet with EVs. The Nissan e-NV200 Combi "does everything the Leaf does but is much bigger and offers more space," says Richards. "We'll definitely be ordering more."

The US Department of Energy has released a new report on EV charging behavior and its impact on the grid. The report, which covers grant projects from six different utilities, includes data from over 270 public chargers and 700 residential charging units. Most at-home charging took place at night during off-peak hours. There were some reports of problems with chargers and smart meters working together. Most public charging took place during peak hours, but was low compared to home charging. This means a longer cost recovery period due to the high cost of installation. See the report at the DOE website or read more at Green Car Congress. The Renovo Coupe will be on display at the NVIDIA booth at the 2015 Consumer Electronics Show (CES) for its first public viewing. Renovo Motors CEO Christopher Heiser says, "These are very exciting times for Renovo and we think our new technology, coupled with NVIDIA's breakthroughs in automotive applications, has the potential to make a tremendous impact across the entire automotive industry." The Shelby Daytona-bodied Renovo offers 500 horsepower and 1,000 pound-feet of torque from two electric motors.

2015 Nissan Juke keeps its funky

The Nissan Juke is one of the most polarizing vehicles on the road today, but that doesn't mean it hasn't been a sales success, especially in Europe. Nissan is giving the the CUV its first styling refresh at the Geneva Motor Show. While the design changes will almost certainly be universal, the mechanical changes are still somewhat of a mystery for the US market. Nissan makes it clear in its press release below that it covers only the European model, and details about the North American model are coming later.
The exterior changes put a focus on making the Juke look a bit more angular and sporty. The lights on the fenders are now formed into a jagged point and somewhat echo the boomerang-shaped taillights. It also features Nissan's new, thicker V-shaped chrome grille. The door mirrors receive LED turn signals, and the lower portion of the rear receives a simulated mesh grille to look more aggressive. Other than some new color schemes, the interior is basically unchanged. However, the luggage area has been reshaped to increase storage capacity by 40 percent to 12.5 cubic feet (354 liters).
European buyers are getting a new 1.2-liter DIG-T turbocharged engine with 113 horsepower (115PS) and 140 pound-feet of torque (190Nm), and the 1.6 DIG-T also gets an increased compression ratio to produce 188 hp and is offered with either a six-speed manual or Nissan's Xtronic CVT. The all-wheel-drive system has also been upgraded with a torque vectoring system.
