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

Mercedes-AMG previews new C63 Coupe ahead of August 19 reveal

Mercedes has been spending the month of July preparing us all of the debut of the new AMG-fettled C-Class coupe. It dropped an enigmatic teaser video on us at the beginning of the month, followed by a handful of teaser images, and another video after that. Now it's released another batch of images to give us a taste of what to expect. These prototype pictured is still heavily camouflaged, so there's little more to tell from them than we already saw from the spy shots we brought you back in April. We can see the front end a bit better, bearing what looks like the same lower air dam as the C63 sedan, but everything save for the front part of the greenhouse is covered up in the swirly stuff. While the photos posted on the Mercedes-Benz Facebook page refer to this as the C63 Coupe, the AMG post references the Mercedes-AMG C-Class Coupe. Either way, we're expecting it to pack the same 4.0-liter twin-turbo V8 as the sedan (as well as the AMG GT), likely to be made available once again in 469- and 503-horsepower states of tune. Affalterbach has also posted a countdown timer on its website, with 23 days left to go until the new muscle coupe makes its debut. So mark your calendars for August 19, and watch this space for more as the German automaker is sure to keep trickling out more photos, videos, and information between now and then. Related Video:

Mercedes goes boating again with G63 AMG-inspired Cigarette

Cigarette Racing has another Mercedes-Benz AMG-themed boat headed out to sea. After The SLS AMG-inspired 46-foot Rough Rider in 2010 and the C63 AMG Black Series-inspired 50-foot Marauder in 2012, this year's Miami Boat Show will introduce the 42-foot Huntress, theme provided by the G63 AMG.
The latest Cigarette homage is less overly racy than the ones before, befitting a watercraft modeled off a performance SUV, but don't let the looks fool: there are five Mercury Racing Verado 350SCi outboard engines, each one of them packing a supercharged inline six-cylinder with, natch, 350 horsepower. Those 1,750 horses will be good for 78 miles per hour when you've got some saltwater underneath you.
If you're in South Florida this week, Booth B-23 at the Miami Convention Center could be your best place to see it. Otherwise, like the 536-hp G63 AMG, it could be hard to catch. There's a press release with more information below.
