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

2020 Cadillac XT4 Sport Drivers' Notes | Worth a look, or two

The 2020 Cadillac XT4 is Cadillac’s smallest crossover in its burgeoning lineup of SUVs. Most of the attention is on the new Escalade these days, but the XT4 is where someone with a lighter budget might enter the Cadillac brand. Our tester happens to be the Sport model, giving it a distinctive appearance, separate from the Luxury and Premium Luxury trims. This one has a gloss black mesh grille, black trim throughout the exterior and Sport-specific wheels — the others rely much more heavily on chrome. Cadillac stepped it up in the design studio for the XT4, as one of its best qualities is the exterior design. It compares well to other small crossovers and doesn't look like your typical cookie-cutter crossover on the road. ThereÂ’s only one engine available, and itÂ’s a 2.0-liter turbocharged four-cylinder that makes 237 horsepower and 258 pound-feet of torque. When the XT4 came out for the 2019 model year, this engine was brand new. Today, Cadillac is passing it around the lineup to vehicles like the CT5 and CT4. A nine-speed automatic transmission is the only transmission option, as well. Our tester has all-wheel drive, but front-wheel drive is standard on lesser XT4s. There isnÂ’t a whole lot changed for the 2020 model year, but Cadillac did add an “Off Road” mode and made a bunch of safety equipment standard. With our test car being a Sport trim with all-wheel drive equipped, the base price is $42,295, a fair bit greater than the $36,690 standard car. After options, our XT4 totaled $48,310. The most expensive extra is a $1,500 Bose Centerpoint audio system, combined with navigation. An $1,100 Driver Assistance package brought adaptive cruise control, enhanced automatic emergency braking and reverse automatic emergency braking. A Cold Weather package added heated seats all around and a heated steering wheel for $850. Finally, the $470 Driver Awareness package brought automatic high beams and lane-keep assist. Senior Editor, Green John Beltz Snyder: This one grew on me the more I drove it. I was unconvinced for the first part of my drive, but then things started to feel more well-though-out as I used them. For instance, the line of buttons across the center stack looks daunting, until you turn the car on and their labels are illuminated. Then everything is easy to find thanks to the lighting, symmetry and the fact that you only have to look down a single line of buttons rather than hunt around a grid pattern.
