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

11 vehicles from Barrett-Jackson Las Vegas worth watching

This weekend will see the world's collector car crowds descend on Las Vegas, NV for one of the biggest shows on Barrett-Jackson's popular auction circuit. There are hundreds of vehicles up for bidding, ranging from a brand-new Lamborghini Aventador to a spattering of Art Deco classics and a huge swath of classic muscle cars.
While it's virtually impossible to assemble an inarguable list of the best cars coming during the three-day, 700-plus vehicle auction, we've sifted through the listings for this year's show - it was a tough assignment, we promise - and assembled a list of what we think will be some of the most interesting lots. We'll admit, it's a bit heavy on American iron, but if you browse BJ's listings, you'll come to a similar conclusion. Still, scroll down for our list of what we think will be the most interesting vehicles at the upcoming auction.

Peugeot's American future looks dead, but Stellantis intends to keep all brands alive

The years-old promise of a Peugeot return in the U.S. is looking bleaker by the second. Peugeot said the French brand would come back to sell cars in the U.S. five years ago, but now that FCA and PSA have transitioned to one Stellantis, that promise is looking a lot shakier. This news comes via a report from Car and Driver. When queried about Peugeot, Carlos Tavares, Stellantic CEO, offered this in response: “For the time being, I don't think that is part of the things that we want to prioritize for the next time window," Tavares said. "I think it's better that we funnel the talent, the capital, and the engineering capability of our Stellantis company to the existing brands to improve what needs to be improved and to accelerate where we need to accelerate, because we already have a very strong presence in this market." Tavares hasnÂ’t ruled it out entirely, but any kind of a Peugeot American renaissance is being pushed onto the backburner.  In good news for American brands, though, Tavares expressed great interest in keeping them all. Chrysler was the most worrisome of the bunch, as it only sells the aging 300 sedan and Pacifica minivan variants. Nevertheless, Tavares sees Chrysler as one of the “three historical pillars of Stellantis” and is eager “to give this brand a future.” Specifically, Tavares sees a high-tech future for the once-great American car company. Motor Trend reported on what Tavares spoke about in a call with the media. "It needs to rebound,” Tavares said. “We could think about what could be the next technologies in the automotive industry.” The obvious hint here is electrification and greater autonomy. Chrysler could theoretically become StellantisÂ’ electric showcase brand. ItÂ’s partway there with the Pacifica Hybrid PHEV minivan, but thereÂ’s still a long way to go for it to become the conglomerate's tech pillar. And then thereÂ’s Dodge and its powerful but emissions-heavy lineup. "We have the technology to deliver the torque, dynamics, and acceleration feeling, while also dramatically reducing the emissions," Tavares said. The Hellcat canÂ’t have a window-shattering 6.2-liter supercharged V8 forever, but it looks like Stellantis is at least committed to keeping the performance of DodgeÂ’s current lineup. Related video:
