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.

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

Sunday Drive: Spying an automotive future of performance

I spy, with my little eye ... the future of the automotive world here in the United States. That pretty much sums up this week's Sunday Drive, in which we pull out the most popular stories on Autoblog of the previous week and try to draw some sort of conclusion as to what binds them all together. This week, it's spy shots, starting with one of the biggest and baddest muscle cars the world has ever seen: the Dodge Challenger Hellcat. The Hellish coupe gets a new hood for 2019 with dual scoops, but that's about the only meaningful change for the new model year. No matter. As long as it's packing 700-plus horsepower under those two hood scoops, all will be right with the world. Moving on, we take keep the performance angle but move it from the street to the dirt with a new version of the Chevy Colorado ZR2 that we think is probably called the Bison. We think it'll keep the high-tech suspension bits of the regular ZR2, but add expedition gear that may include a snorkel and a winch. Which, if true, is pretty dang cool. Keeping the truck theme is the 2019 GMC Sierra. There's nothing particularly noteworthy about the trim level in which the truck was spied, and that's what makes this specific example interesting. Base-model trucks almost never get much attention, but they sell in droves to workers who need an honest-to-goodness truck for work or play and don't care about bells, whistles, or massive chrome badges. And finally we have the 2018 Jeep Wrangler, which is on fire on the sales floor right now. But those are all V6-powered Wranglers flying off the showroom floor. Soon, a turbocharged four-cylinder engine option will become available, and now we know that it will return up to 23 miles per gallon in the city and 25 on the highway. That makes it the most fuel efficient Wrangler that Jeep has ever sold. As always, stay tuned to Autoblog this week for all the automotive news that's fit to publish. 2019 Dodge Challenger Hellcat with twin-scoop hood spied with no camouflage Chevy Colorado ZR2 Bison caught testing 2019 GMC Sierra 1500 spied in base trim level 2018 Jeep Wrangler four-cylinder fuel economy revealed Spy Photos Chevrolet Dodge GMC Jeep Truck Coupe SUV Off-Road Vehicles Performance dodge challenger srt hellcat sunday drive

Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.
