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

Hotter Cadillac ATS-V+ could use LS7 power

Rumor has it Cadillac is working on an even hotter version of the ATS-V, possibly called ATS-V+. And the latest intel from Motor Trend suggests this new model might have a great, big V8 under the hood. The V8 in question is the high-revving, naturally aspirated 7.0-liter LS7 from the Camaro Z/28. The hand-built engine makes 505 horsepower and 481 pound-feet of torque in the Z/28 – a nice increase over the 464 hp and 445 lb-ft in the standard ATS-V, which uses a twin-turbocharged 3.6-liter V6. Motor Trend says the ATS-V+ will come to market with an eight-speed automatic transmission, as well as the seven-speed manual 'box from the Corvette. A dual-clutch transmission will come to market later. Of course, we'll believe it when we see it. But an LS7-powered ATS-V sure sounds like a great package to us. Here's hoping.

Cadillac to move select offices from Detroit to Manhattan?

Under Johan de Nysschen, Infiniti moved its headquarters from Yokohama, Japan, to Hong Kong. Now at Cadillac, it appears the company's new president could be planning a relocation of at least some of the brand's operations from Detroit to Manhattan, according to a new report from Reuters.
In the case of Infiniti, de Nysschen pushed for the move because moving away from the brand's Nissan overlords would allow it a bit more freedom. It's evidently a similar case for Cadillac, with Reuters speculating that such a move would help distance the brand from the corporate culture in Detroit. A Big Apple move could also attract new talent that may have considered a job with the brand but were put off by the idea of living in Detroit.
It's important to note that if such a move takes place, it likely won't affect the folks actually responsible for developing the brand's vehicles. Instead, administrative functions, including marketing, could be the focus of the relocation.
