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.

Chrysler, Nissan looking into claim that their cars are industry's most hackable

A pair of cyber security experts have awarded the ignominious title of most hackable vehicles on American roads to the 2014 Jeep Cherokee, 2014 Infiniti Q50 and 2015 Cadillac Escalade.
Charlie Miller and Chris Valasek are set to release a report at the Black Hat hacking conference in Las Vegas, Automotive News reports. The two men found the Jeep, Caddy and Q50 were easiest to hack based not on actual tests with the vehicles, but a detailed analysis of systems like Bluetooth and wireless internet access - basically, anything that'd allow a hacker to remotely gain access to the vehicle's systems.
Considering this lack of hands-on testing, the pair acknowledge that "most hackable" could be a relative term - they point out that the vehicles may actually be quite secure.

Nissan NV400 becomes Japan's first electric ambulance

Consumer passenger cars aren't the only vehicles undergoing electric transformations. We've seen the introduction of early electric fire trucks, and now Japan is getting its first electric ambulance. It's a Nissan NV400, and it will be used by the Tokyo Fire Department at the Ikebukuro station. Though badged as a Nissan, the NV400 is at its heart a Renault Master Z.E. electric van. The powertrain is the same as the French van with a 33-kilowatt-hour battery (7 kWhs less than the base Nissan Leaf) and a 55-kW motor driving the front wheels. That translates to 74 horsepower and 162 pound-feet of torque. That doesn't sound like much, but in as dense a city as Tokyo, it's not likely the NV400 will be able to reach high speeds at all, even if it had a Hellcat engine. There are a couple of unique additions to the van to enhance its ambulance capability. One is the inclusion of a separate 8-kWh lithium-ion battery that can operate all the equipment on board for long periods of time without eating into the ambulance's range. It can even be used like a generator to provide power to external emergency equipment. Then there's the stretcher, which Nissan vaguely says is electrified to make it easier to use by the medical personnel. We presume the stretcher has an electric motor to make it easier to push around. Since neither the NV400 nor its Renault counterpart is sold here, we're not expecting to see one of these ambulances in the U.S. any time soon. But electric versions of local emergency vehicles seem like a good idea, since range wouldn't be an issue, and the torque would be useful in large vehicles. Ford is readying an electric full-size Transit, which is offered in America in gas versions. Perhaps we could see some electric Ford ambulances in the near future. Related Video:
