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

Cadillac plans new branding campaign to go with new products

Cadillac's new leader says the GM luxury brand now has "thousands of people" working on its behalf back at its soon-to-be new headquarters in the Detroit suburb of Warren, with a new branding campaign under development and plans to fix longstanding quality issues. Cadillac President Steve Carlisle granted an interview with the Detroit Free Press in which he said he'll unveil a new strategy to redefine the luxury brand, which he's calling a "master brand," in the first quarter of 2019. "Cadillac has its own values — boldness, optimism, innovation, sophistication — that will reflect in the master brand," Carlisle told the outlet. The challenge is "how to bring those to life." He added that Caddy won't be defining itself simply as a viable option to gold-standard Germany luxury cars. "We're targeting customers versus competitors. Cadillac has to have its own persona and not be defined by where other brands are and are not. It has to have its own definition and that's what we're reflecting in our master brand." Carlisle, who was promoted to lead Cadillac in April, put his first stamp on Cadillac last month when the brand announced it will move its headquarters back to Warren, Mich., across the street from GM's massive Tech Center, after more than three years in Manhattan's SoHo neighborhood. He said its Cadillac House showroom, a ground-floor space used to display models and stage events with partners, will remain open "for the time being" and that the brand will use what it learned well outside of its Detroit auto-industry bubble to move the brand forward. He'll have his work cut out for him. Cadillac plans to launch a new or redesigned vehicle every six months for the next three years, and Carlisle said he wants the brand to be GM's technology leader, the first to deploy self-driving and electric-vehicle technology of GM's stable of brands. Yet the brand just ranked second-from-last in Consumer Reports' new reliability survey for 2018. Jon Linkov, deputy auto editor for CR, said the brand suffered for widespread complaints about its Cadillac User Experience infotainment system, with owners reporting frequent crashes, frozen screens and problems with voice control. "Most of (the complaints) really ran through the CUE system being a major culprit for Cadillacs," Linkov said. Through September, Cadillac's year-to-date sales had dipped a half a percentage point from the first nine months of 2017 to 113,240 units.

GM faces possible class action lawsuit over 8-speed transmission

General Motors has been hit with a class-action lawsuit from owners who allege the eight-speed automatic transmission found in several rear-wheel-drive Chevrolet, Cadillac and GMC models between the 2015 and 2019 model years has a defect that causes the vehicles to hesitate and jerk when accelerating or slowing down. The lawsuit was posted to ClassAction.org and spotted by GM Authority. Problems with GM's Hydra-Matic 8L90 and 8L45 transmissions have been well-documented on Internet forums and via complaints filed with the National Highway Traffic Safety Administration, with many reporting damage to their vehicles. The lawsuit was first filed in December in U.S. District Court for the Southern District of Florida but appears to have been transferred recently to New York. Autoblog sought comment from Theodore Leopold, the lead attorney for the plaintiffs. "These transmissions have a common defect," the complaint reads. "Drivers attempting to accelerate or decelerate their cars feel a hesitation, followed by a significant shake, shudder, jerk, clunk, or 'hard shift' when the vehicle's automatic transmission changes gears." The problem also occurs when the vehicles accelerate in a single gear, without shifting, the plaintiffs allege. "Drivers have reported that the shift is sometimes so violent, they feel as though they have been hit by another vehicle." The problem is believed to center on the transmission, torque converter or both. The complaint says it causes undue friction, causing hydraulic systems and gears to function improperly and sometimes leaves metal shavings throughout the transmission, leading to costly repairs and replacement of parts or the entire transmission. It says GM has known about the problems since shortly after it introduced the transmissions, and has issued 13 technical service bulletins, none of which have resolved the problem. GM declined to comment on the lawsuit. The plaintiffs say GM should have warned consumers about the issues and covered repairs under each vehicle's three-year/36,000-mile bumper-to-bumper warranty. They're seeking statewide classes in at least six states: California, Florida, Illinois, New York, Oklahoma and Texas.
