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.

2019 Chicago Auto Show Truck Roundup: Toyota, Ford, Chevy and Ram bring it

The 2019 Chicago Auto Show features an array of heavy-duty trucks, smaller trucks, other kinds of trucks, and well, more trucks. That means new versions of the 2020 Chevy Silverado Heavy Duty and 2020 Ford F-150 Super Duty, a refreshed 2020 Toyota Tacoma and a trick tailgate on the 2019 Ram 1500. Sound a little crazy? Morgan Stanley research says 68 percent of passenger vehicles sold in the United States last year were classified as light trucks. So actually, bring on the trucks! Here's some impressions on the Chicago reveals, plus our take on the 2020 Subaru Legacy sedan. — Toyota updated the 2020 Tacoma with some light but useful enhancements. An improved infotainment has new audio features and larger screens. The grilles and wheels are different, but nothing drastic. Toyota still offers nice differentiation across the Tacoma lineup, and the design tweaks are subtle but thoughtful. Toyota tends to stretch out the Tacoma's generations, so it's wise to keep modifying and iterating to keep pace in this competitive segment. — Staying with Toyota, the Land Cruiser Heritage Edition is a legit special model that fans of this historic nameplate will appreciate. An anchor of the Toyota line in the United States since 1958, the Land Cruiser's roots date to Toyota's 1951 BJ Series military vehicle. Two colors, Midnight Black and Blizzard Pearl, are exclusive to this model and look slick against the blacked-trimmed grille and lightly bronzed wheels. Inside, bronze stitching is used on the steering wheel, seats, center console and other parts. The best part? Land Cruiser spelled out in script on the rear pillar. It's a limited model (1,200 units) and pricing isn't out yet, but that badge is probably why you buy this SUV. — The 2020 Chevy Silverado HD gets imposing looks that differentiate it from the light-duty range, an eye-popping max towing capability of 35,500 pounds and some updated powertrain elements. A new gas-fed V8 that serves as the entry point is one of the highlights, and the 6.6-liter mill makes 401 hp and 464 lb-ft, up significantly over the old 6.0-liter. There's also a new Allison 10-speed transmission teaming with the Duramax diesel to achieve that lofty max towing figure. With an updated trailering system and a larger cabin, the Silverado HD range is comprehensively remade to fight Ram and Ford. — The 2020 Ford Super Duty is also redone, and like the Chevy line, it gets a new gas V8 checking in at 7.3 liters.

U.S. and Toyota Reach Settlement Over Safety Problems Disclosure

The U.S. has reached a $1.2 billion settlement with Toyota Motor Corp., concluding a four-year criminal investigation into the Japanese automaker's disclosure of safety problems, according to a person close to the investigation. Attorney General Eric Holder, Transportation Secretary Anthony Foxx and U.S. Attorney for the Southern District of New York, Preet Bharara, were announcing the settlement Wednesday morning, said the official, who spoke on condition of anonymity because the official was not authorized to discuss the settlement on the record before the announcement. TOP 5Most Researched Green Cars On AOL Autos 2013 Honda Fit EV MSRP : $36,625 2014 Chevrolet Spark EV MSRP : $26,685 2012 Mitsubishi i-MiEV MSRP : $29,125 2012 Ford Focus Electric MSRP : $39,200 2012 Toyota Prius Plug-in MSRP : $32,000 In a statement early Wednesday, Toyota said it has "cooperated with the U.S. Attorney's office in this matter for more than four years" and had "made fundamental changes to become a more responsive and customer-focused organization, and we are committed to continued improvements." The criminal investigation focused on whether Toyota was forthright in reporting problems related to unintended acceleration troubles. Starting in 2009, Toyota issued massive recalls, mostly in the U.S., totaling more than 10 million vehicles for various problems including faulty brakes, gas pedals and floor mats. From 2010 through 2012, Toyota Motor Corp. paid fines totaling more than $66 million for delays in reporting unintended acceleration problems. The National Highway Traffic Safety Administration never found defects in electronics or software in Toyota cars, which had been targeted as a possible cause. The settlement continues a string of bad publicity for Toyota, which before the unintended acceleration cases had a bulletproof image of reliability. Since the cases surfaced, the company's brand image has been damaged and it has lost U.S. market share as competition has intensified. Last year, Toyota agreed to pay more than $1 billion to resolve hundreds of lawsuits claiming that owners of its cars suffered economic losses because of the recalls. But that settlement did not include wrongful death and injury lawsuits that have been consolidated in California state and federal courts. In December, Toyota filed court papers after a four-year legal battle saying that it's in settlement talks on nearly 400 U.S. lawsuits, but other cases aren't included in the talks.
