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.

Toyota's fuel pump recall now covers nearly 6 million vehicles globally

Toyota expanded a worldwide fuel pump recall to a total of 5.84 million vehicles for a defect that could cause the part to fail. In the United States, the total number of vehicles involved in this safety recall is now approximately 3.34 million vehicles. On January 13, 2020, Toyota announced a safety recall for 695,541 Lexus and Toyota models. In March of 2020, the Japanese automaker added an additional 1.1 million vehicles to the previous recall. Now, the largest Japanese automaker adds another 1.52 million U.S. vehicles to the recall that was first announced in January and covers numerous models built between July 2017 through September. Here is a full list of vehicles that are now included in the expanded recall: 2013-2015 Model Year Lexus LS 460; 2013-2015 Model Year Lexus GS 350; 2014 Model Year Toyota FJ Cruiser, Lexus IS-F; 2014-2015 Model Year Toyota 4Runner, Land Cruiser; Lexus GX 460, IS 350, LX 570; 2015 Model Year Lexus NX 200t, RC 350; 2017 Model Year Lexus IS 200t, RC 200t GS 200t; 2017-2019 Model Year Toyota Highlander; Lexus GS 350; 2017-2020 Model Year Toyota Sienna and Lexus RX 350 2018-2019 Model Year Toyota 4Runner, Land Cruiser; Lexus GS 300, GX 460, IS 300, IS 350, LS 500h, LX 570, NX 300, RC 300, RC 350; 2018-2020 Toyota Avalon, Camry, Corolla, Sequoia, Tacoma, Tundra; Lexus ES 350, LC 500, LC 500h, LS 500, RX 350L 2019 Model Year Toyota Corolla Hatchback and Lexus UX 200 2019-2020 Model Year Toyota RAV4 Toyota said the vehicles that have a fuel pump that may stop operating and could result in a vehicle stall, and the vehicle may be unable to be restarted. Dealers will replace the fuel pump with an improved version. Toyota's customer support is available to owners with affected vehicles by calling the Toyota Brand Experience Center at 1 800 331-4331.

Cleanliness of Toyota Mirai fuel cell exhaust depends on air quality

Is the water vapor coming out of Toyota's first production fuel-cell vehicle drinkable? If you're driving through the Sierra Nevadas? Probably. Cruising through Beijing? Not so much. Toyota executive Seiji Mizuno discussed whether the water vapor emitted from the Toyota Mirai is safe enough to drink and, according to Automotive News, the short answer is "yes," since the slightly-acidic vapor has "fewer organic impurities" than milk. The catch, though, is that the vapor immediately gets mixed with the surrounding air. That means that there's always the chance that something funky gets mixed in with the air intake, especially if the Mirai's driving through a smog-infested city. That makes the idea of swigging off the tailpipe a slightly riskier venture, so it's best to keep that reusable bottle full of tap water handy. Toyota, which recently showed the Mirai off at the Los Angeles Auto Show, confirmed earlier this month that the Mirai would start sales in California in 2015 with lease rates starting at $499 a month. While the model's MSRP will be $57,500, federal and state incentives could bring that number to less than $45,000. Fewer than 200 Mirai vehicles will be available in the US by the end of next year.
