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.

2021 GMC Canyon trims overhauled, SL and SLT disappear

Until this year, the GMC Canyon has offered six trims in two drivetrains: SL, a base model simply called Canyon, SLE, All Terrain, SLT, and Denali, with all but the SL available in either 2WD or 4WD. GM Authority credits "dealer sources" for news that the 2021 Canyon has had its trim steps overhauled. According to the chart in the report, the SL and SLT are no more, the base Canyon gets replaced by a trim called Elevation Standard, and SLE turns into Elevation. We already know that All Terrain has given way to AT4, while Denali remains in the top spot. Trim content doesn't change with the names, but there's no equivalent for the SLT trim in terms of spec. The GMC site lists the 2020 SLE and SLT on the same page, and a shopper must burrow into the spec comparison page to figure out the differences. The SLT only comes with the 3.6-liter V6 and eight-speed transmission, and makes features like remote start, climate control, heated mirrors, heated seats, hitch guidance, and a spare tire standard equipment. It also chromes the exterior door handles, and offers a Cocoa/Dune leather interior that can't be had on the SLE. It's possible the SLT's $4,700 premium over the SLE led more buyers to start with the SLE and add the engine and options they wanted.   We have a number of questions that we'll need to wait for GMC's official announcement to answer. The 2020 Canyon offers an Elevation Edition package for $650 that adds a black grille with body-colored surround, and 18-inch Satin Graphite wheels in all-terrain rubber. There's also a California Elevation Special Edition for $1,195 with all-weather floor liners, assist steps, and mud flaps. They could be optioned on the SLE but not the SLT. With the addition of two Elevation trims, we'll find out if the packages get renamed or go away. Separately, CarBuzz spotted a 2021 GM Fleet Order Guide that mentions a leveling kit option, LPO Code SQS, for the Canyon and the Chevrolet Colorado. We noted the inclusion of a leveling kit in the coming Canyon AT4 Off-Road Performance Package. According to the order guide, the option can be ordered only for the Canyon AT4 trim, but it's not clear if that's an a la carte choice or if buyers must order the Off-Road Performance Package. On the Chevy, the rake-removal equipment can be had with the Colorado 4x2 Z71 or the 4x4 Work Truck, LT, and Z71. Related Video:

The biggest gas-guzzlers of 2024: 'The Meanest List' is the opposite of greenest cars

In some circles — especially some automotive circles — bigger is better. This explains the Hummer, for example. In its so-called “Meanest List” of a dozen models, the American Council for an Energy-Efficient Economy (ACEEE) makes no apologies for berating “the worst-performing mass market automobiles” sold in 2024 in the U.S. The most diminutive car on the list is a Chevy Corvette Z06. At the top of this particular heap is the Mercedes-Benz AMG G63, a gas-powered SUV that the environmental agency says was “the worst-performing vehicle of the more than 1,200 models assessed by Greener Cars and has an annual fuel cost over $4,000.” Not to mention its MSRP of around $184,000. Rank Make & Model Powertrain Green Score MSRP Estimated Annual Fuel Cost* 1 Mercedes-Benz AMG G63 Gas 20 $184,000 $4,242 2 Ram 1500 TRX 4x4 Gas 22 $98,335 $3,819 3 Ford F150 Raptor R Gas 24 $79,975 $3,777 4 Cadillac Escalade V Gas 26 $152,295 $3,388 5 Dodge Durango SRT Gas 26 $74,995 $3,332 6 Jeep Wrangler 4dr 4X4 Gas 27 $35,895 $3,260 7 Jeep Grand Wagoneer 4x4 Gas 28 $91,945 $3,058 8 Mercedes-Benz G550 Gas 28 $143,000 $3,186 9 GMC Hummer EV SUV EV 29 $98,845 $1,746 10 GMC Sierra Gas 29 $37,700 $3,069 11 Chevrolet Corvette Z06 Gas 30 $114,395 $3,169 12 Mercedes-Benz Maybach S680 Gas 30 $234,300 $3,031 *ACEEE analysis using EIA data of the annual cost of driving 15,000 miles In terms of numbers, the dirty dozen of the meanest includes seven SUVs and three trucks. Lonely at the middle of the list is the sole electric, the GMC Hummer EV, which weighs in at 9,000 pounds. The council notes that “though EVs have lower emissions than similarly sized gasoline models, the Hummer demonstrates that size and efficiency, not just fuel source, are important factors in a carÂ’s environmental impact.” ItÂ’s also worth reminding prospective buyers that the average fuel cost of a vehicle on the “Greenest List” eats up only a fifth of the fuel cost of a vehicle on the Meanest List, “showing that greener options can also be more affordable.” The ACEEE also put out a "Greener List" of efficient gasoline and hybrid cars that don't require plugging in.  By the Numbers Green Cadillac Chevrolet Dodge Ford GMC Hummer Jeep Maybach Mercedes-Benz RAM Emissions Fuel Efficiency Green Automakers Truck SUV Electric Hybrid
