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.

A few pre-race notes and a lot of photos from the 24 Hours of Le Mans

The 82nd running of the 24 Hours of Le Mans is on.
Audi has won 12 of the last 15 events, the scion of Auto Union is trying to make it 13 this year. To do so, it will have to overcome a situation faced only three other times during its dominance of La Sarthe: underdog status. Toyota has won the first two races of the year and claimed pole for this race, the rumor being that this year it's Toyota's race to lose.
And then there's Porsche. It's been 16 years since the Stuttgart brand raced on the top rung at Le Mans, three years years since it announced its return, just a year since it acquired Mark Webber in a signing that wasn't subtle and a few months since we got eyes on the 919 Hybrid.

What to do if the infotainment in your Lexus isn't working

According to Toyota, "errant data from our traffic and weather data service provider" caused the infotainment systems in 2014-2016 Lexus vehicles and the 2016 Toyota Land Cruiser to go into some sort of endless reboot loop. The video above shows what that looks like, in case you're interested. Obviously, it's not good – the malfunction means the audio systems, navigation and climate control systems aren't working properly, and that the hands-free mobile phone function won't work. Apparently, some owners were able to manually fix their cars by disconnecting the battery cables for 10 minutes, which forces the car's computer systems to restart. But Toyota isn't officially suggesting that people take that action. Instead, "Toyota and Lexus owners experiencing these issues should visit their dealer for a complimentary system reset and a confirmation of the system," the automaker said in a statement. It's worth noting that issues with the usability of modern infotainment systems have caused customer satisfaction scores to drop. Lexus, though, has been mostly immune to such complaints, having come in first place in J.D. Power's most recent Vehicle Dependability study. Not that you should automatically trust those findings, anyway... Related Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.
