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

Chevy Colorado configurator goes live as GM touts fuel efficiency

While the news of today is destined to be dominated by a certain plucky Japanese roadster, props to Chevrolet and GMC for announcing its own significant bit of news about their newest pickup twins, the midsize Colorado and Canyon. The two GM-owned brands announced that the twins' 3.6-liter V6 will return up to 26 miles per gallon on the freeway.
To get such efficiency from the 305-horsepower mill, you'll need to live without four-wheel drive and be okay with a max city fuel economy of 18 mpg. The combined rating for the 2WD model sits at 21 mpg. Adding four-wheel drive drops the city and combined ratings by one mpg, while the highway rating dips from 26 to 24 mpg.
As for the twins' eagerly anticipated 2.8-liter diesel engine, it's destined for model year 2016, meaning we've got a ways to go before its efficiency and output are certified.

GMC Hummer pickup and SUV previewed in video, set to be revealed in fall

GMC has just provided us with our first good look at the upcoming Hummer EV pickup and SUV. A video was posted online previewing the two models that also happens to feature LeBron James. From clay sculptures to prototypes in various levels of completeness, GM is allowing the world a sneak preview of what’s to come. A couple of the more revealing images come in silhouette photos of both the truck and SUV at the end of the video. The truck has a big four-door crew cab and an exceptionally small bed behind it. The angle from cab to bed is also notable. ItÂ’s not easy to see exactly whatÂ’s going on since itÂ’s shrouded in darkness, but when we saw the Hummer pickup, it was rocking sail panels that resemble the ones on the truck weÂ’re looking at. The truckÂ’s general shape is off-road oriented with squared-off, sharp lines tracing the entire silhouette. Its big, knobby tires and blocky wheels are clear indicators of what GM was aiming for with this electric pickup. As for the SUV, comparisons to the Ford Bronco four-door will be inevitable. If our eyes are picking up the scale of this photo correctly, though, the Hummer SUV appears to be a slightly larger vehicle than the four-door Bronco is. Although, the wheelbase for the SUV is shorter than that of the Hummer truck. ThatÂ’ll help it off-road. Those small bumpers and short overhangs along with the bumper cutouts should be hugely beneficial to approach and departure angles, as well. Hummer EV prototype View 6 Photos GMCÂ’s shots of the Hummer in the studio are equally as revealing. We can see what looks to be an intense front skid plate and two big tow hooks. In addition to the off-road gear, GMC has allowed a look at the frunk. The front “grille” is one piece with the hood of the truck, so the whole assembly pulls up. That makes for what appears to be a very easy-to-load front trunk compared to other EVs that force you to lift items up and over the front of the car. The whole removable roof assembly is exposed in this video, too. We can see the crossbars that the removable panels attach to and also what the truck looks like with the tops removed. The SUV appeared to have removable roof panels from our short glimpse of it in a studio awhile back. Other new details GM mentioned in the video include Adrenaline Mode, Crab Mode and Next-Gen Super Cruise. We donÂ’t know what Adrenaline Mode or Crab Mode do yet, but theyÂ’re certainly off-road modes that GM has designed specifically for this electric Hummer.
