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

Ford builds USAF Thunderbirds Edition Mustang for charity

Each year since 2008, Ford has created a one-off Mustang to celebrate military aviation, and the cars have been auctioned off at the Experimental Aircraft Association (EAA) Gathering of Eagles charity event to raise money to inspire the next generation of aviators. This year's charity car is the 2014 Ford Mustang GT US Air Force Thunderbirds Edition, which also helps celebrate 60 years of Thunderbirds air show excellence.
Of all the EAA charity cars, this Thunderbirds Edition is the most in depth. Painted to match the F-16 Tomcat fighter jets used by Thunderbirds, this Mustang also gets a widebody kit and 22-inch Forgiato wheels to go with the cockpit's Recaro bucket seats, rear-seat delete and modified navigation screen and gauge cluster. Even the Mustang's projector puddle lights have been changed to show an aircraft silhouette - rather than the Mustang's galloping horse logo - when the doors are open.
Themes for previous EAA charity cars include the Blue Angels, SR-71 Blackbird and the Red Tails as well as the F-22 Raptor-inspired AV8R and AV-X10 "Dearborn Doll" models. Scroll down for the press release for the 2014 Ford Mustang GT US Air Force Thunderbirds Edition, and be sure to check out our galleries for all six aviation-themed Mustangs.

Next Ford Mustang to drop 400 pounds

The Ford Mustang is already the lightest of the current crop of muscle cars, at around 3,600 pounds for a GT coupe with the six-speed manual transmission. That's almost 260 pounds less than a Chevrolet Camaro SS and about 450 pounds less than a Dodge Challenger R/T, which means the Mustang has a pretty big advantage when it comes to handling, braking, accelerating and economy. More good news: The next Mustang will be even lighter.
According to a report from Edmunds, the sixth-generation Mustang, which is set to debut at the 2014 North American International Auto Show, will shed an additional 400 pounds of body fat. That 11-percent weight reduction will be thanks to lightweight materials, with a particular focus on using stronger, but less material in construction. Aluminum will feature heavily, but Edmunds' inside source warns that there is "nothing terribly exotic" coming to the original pony car.
The other big news is that the new Mustang will be smaller overall. It's going to be 15-inches shorter than the 188.5-inch Mustang on sale today, while it'll also be 6.5 inches narrower. Shorter overhangs, both in the front and rear, are also good signs for those that want an agile Mustang.
