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. Rank Make & Model Powertrain Green Score MSRP Estimated Annual Fuel Cost* 1 Mercedes-Benz AMG G63 Gas 20 $184,000 $4,242 2 Ram 1500 TRX 4x4 Gas 22 $98,335 $3,819 3 Ford F150 Raptor R Gas 24 $79,975 $3,777 4 Cadillac Escalade V Gas 26 $152,295 $3,388 5 Dodge Durango SRT Gas 26 $74,995 $3,332 6 Jeep Wrangler 4dr 4X4 Gas 27 $35,895 $3,260 7 Jeep Grand Wagoneer 4x4 Gas 28 $91,945 $3,058 8 Mercedes-Benz G550 Gas 28 $143,000 $3,186 9 GMC Hummer EV SUV EV 29 $98,845 $1,746 10 GMC Sierra Gas 29 $37,700 $3,069 11 Chevrolet Corvette Z06 Gas 30 $114,395 $3,169 12 Mercedes-Benz Maybach S680 Gas 30 $234,300 $3,031 *ACEEE analysis using EIA data of the annual cost of driving 15,000 miles In terms of numbers, the dirty dozen of the meanest includes seven SUVs and three trucks. 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

GM's fullsize SUVs boost highway mileage by nearly 10 percent

We met the redesigned 2015 versions of the Chevrolet Suburban and Tahoe, and the GMC Yukon and Yukon XL at the 2013 LA Auto Show. Improved gas mileage numbers have been announced to go along with the improved exteriors and interiors, with city mileage improving by seven percent and highway mileage going up by nearly ten percent; you'll now get 16 miles per gallon in the city and 23 on the highway.
The only applies to models with the 5.3-liter engine, though, not the premium Yukon Denali and Yukon XL Denali SUVs with the 6.2-liter motor. Still, the 5.3 gets you more power than previously, with 355 horsepower and 383 pound-feet of torque underfoot, on top of the improved fuel economy numbers. The 6.2-liter sticks with official mpg ratings of 15 highway, 21 city. There's a brief press release below with words straight from the horse's mouth.

Costco Auto Program adds the Chevy Silverado and GMC Sierra through July

Costco members lean to the Bowtie when it comes to pickups. The big box store wrote that the Chevrolet Silverado "is currently the most requested Chevrolet and pickup truck through Costco Auto Program and has been for the past 11 years. In the 14 years Costco has partnered with Chevrolet for member-only incentives, the Silverado (when included), has been the top selling vehicle every time." Members can rejoice, because just for the months of June and July, the Costco Auto Program has added the Silverado and the GMC Sierra to its Costco Auto Savings Event. Until July 31, 2024, card-carrying shoppers can get an additional $1,000 discount on top of any manufacturer incentives they qualify for when leasing or purchasing new examples of either. The Auto Savings event includes other vehicles as well, the $1,000 incentive applicable to certain other models from Chevy and GMC, as as well Volvo and Cadillac. Tire kickers considering the Polestar 2 can get $2,000 off.  You can check out our write-up on the Costco Auto Program for all the details and the frequently asked questions. The summary is that the store works with "selected" dealers to refer customers to, about 3,000 storefronts across most automotive brands. The program comes with no-haggle pricing for any straight-up purchase. Costco offers customers a research tool to check out vehicles by type and compare specs and features. After a customer zeroes in on a car, it's time to visit the dealership for a chat with an "Authorized Dealer Contact" to examine the vehicle and go over the fine print. Haggling would only arise if the customer has a trade-in; that valuation is between the customer and the dealer. The customer can check out the Costco Member-Only Price Sheet, which "displays your prearranged pricing. The savings can be displayed in one of two ways: One version lists pricing for all models available at the participating dealership; the other will show a VIN-specific price based on the vehicle you select, including any applicable manufacturer incentives or rebates." And for those looking on the battery-powered shelves, the program offers the same $1,000 off the Chevy Blazer EV and Equinox EV.
