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

EPA suspected Fiat Chrysler of using 'defeat device' in 2015

U.S. regulators told Fiat Chrysler Automobiles in November 2015 that they suspected some of the automaker's vehicles were equipped with secret software allowing them to violate emission control standards, according to emails disclosed on Friday. The U.S. Environmental Protection Agency and California Air Resources Board accused Fiat Chrysler in January of using the software, known as a "defeat device," to illegally allow excess diesel emissions in 104,000 Jeep Grand Cherokees and Dodge Ram 1500 trucks built between 2014 and 2016. Byron Bunker, director of the EPA's Transportation and Air Quality compliance division, said in a January 2016 email to Fiat Chrysler, obtained by Reuters under the Freedom of Information Act, that he was "very concerned about the unacceptably slow pace" of the automaker's efforts to explain high nitrogen oxide emissions from some of its vehicles. Nitrogen oxide is linked to smog formation and respiratory problems. Bunker's email said the EPA had told Fiat Chrysler officials at a November 2015 meeting that at least one auxiliary emissions control device on the car maker's vehicles appeared to violate the agency's regulations. Mike Dahl, head of vehicle safety and regulatory compliance for Fiat Chrysler's U.S. unit, responded in a separate email that the company was working diligently and understood the EPA's concerns. He added that if the EPA identified Fiat Chrysler vehicles as containing defeat devices it would result in "potentially significant regulatory and commercial consequences." The documents redacted the vehicles named, but two officials briefed on the matter said they referred to diesel models. The EPA's November 2015 meeting with Fiat Chrysler came two months after Volkswagen AG, mired in a major tailpipe emissions scandal, admitted to installing secret defeat device software in hundreds of thousands of U.S. diesel cars to make them appear cleaner than they were on the road.

Stellantis will give its brands 10 years to prove they deserve to live

Formed by the merger of PSA Peugeot-Citroen and Fiat-Chrysler Automobiles, Stellantis has 14 brands under its roof, a number that makes it one of the largest groups in the industry. Rumors claimed not every brand would survive, with Chrysler often earmarked to get axed, but the firm said it will give them all a chance to shine. "We're giving each (brand) a chance, giving each a time window of 10 years and giving funding for 10 years to do a core model strategy. The CEOs need to be clear in brand promise, customers, targets, and brand communications," announced Stellantis boss Carlos Tavares during the Financial Times' Future of the Car event. His comments confirm Chrysler fans and dealers don't need to worry about the future — at least not yet. And, against all odds, Lancia enthusiasts can breathe a sigh of relief, too. Former FCA head Sergio Marchionne warned of the brand's demise on several occasions. Alfa Romeo is safe for now, too, as is Vauxhall, which are basically just Opels sold in the United Kingdom with a different badge. The engagement made by Tavares also means Stellantis won't divest any of its brands to raise capital until at least 2031. It's now up to each executive team to make a case for the brand they run, an unusual survival-of-the-fittest strategy in an era when cutting costs is more common than spending cash. Diving into the vast Stellantis parts bin should help even the most troubled brands turn their fortunes around on a relatively tight budget. It seems likely that survive Chrysler will need to look beyond the 300 and the Pacifica/Voyager, the only models in its range, and completely reinvent its image, which is currently nebulous at best. Lancia, once the champion of luxury, performance, and innovation, faces the same challenge. It's not starting quite from scratch, it's relatively popular in its home country of Italy, but it will need to think globally and expand outside of the city car segment to survive.
