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

The Mansory Speranza proves that money can buy taste and good sense...

...Just kidding.
No one in their right mind has ever accused German tuners Mansory of being subtle. So, when our Geneva team wandered across the Mansory Speranza - A Mercedes-Benz Gelandewagen that has been denuded of its roof and spackled inside with quilted leather and red carbon fiber ­- they didn't ask a lot of existential questions. Why does the Speranza exist? Because Germans are weird sometimes, that's why.
Forget for a moment that you'll have to pay Mansory hundreds of thousands of euros (we're guessing, no pricing information has been revealed) for the privilege of converting your G-Class into something that looks like a Suzuki Samurai, and prepare to be impressed by the details. The tuning house has increased the output of the Mercedes V8 to a healthy 700 horsepower and 668 pound-feet of torque. The wheels are 24-inches, and wear almost unbelievable 305-section ultra-high performance Vresdestein tires. Carbon fiber can be found nearly everywhere one looks, including making up the housing for the spare tire. Oh, and there are leather pillows for the backseats... no word on whether they're standard or optional, but we're looking in to it.

Mercedes updates G-Class including new 4.0-liter twin-turbo V8 [UPDATE]

UPDATE: Information on US availability (including corrected output figures) added to the revised text below. Mercedes has been building (or having Magna Steyr build) the G-Class for an unfathomable 36 years now. Needless to say, the legendary off-roader wouldn't still be around if not for the occasional update here and there, and that's just what the German automaker announced today. The list of enhancements to the iconic Gelandewagen is almost as long as its lifespan, but the most salient point here is the introduction of a new engine. The revised G550 introduces a new 4.0-liter twin-turbo V8, based on the high-performance engine in the Mercedes-AMG GT and C63, but retuned: in this application, it produces 416 horsepower and 450 pound-feet of torque (compared to 453 hp and 440 lb-ft in the GT or 503 and 480 in the GT S). We'd expect that engine to gradually make its way into other models as well. Though the G500 is the only one with a completely new unit, the other engines in the lineup have also been updated. The G350d bumps from 211 hp and 398 lb-ft to 245 hp and 442 lb-ft, the AMG G63 jumps from 536 hp to 563 (torque remains constant at 560 lb-ft), and the top-of-the-line, twelve-cylinder G65 (which we'll be getting Stateside for the first time) now produces 621 hp and a massive 738 lb-ft. Those figures result in a 0-62 time of 8.9 seconds for the diesel, 5.9 for the G500, 5.4 for the G63 and 5.3 for the G65 – which are altogether might impressive for a vehicle as big and boxy as the G-Wagen. All but the G65 now feature stop/start systems to help reduce fuel consumption too. Benz also revised the suspension tuning (while offering optional active dampers) and reprogrammed the ESP, ASR and ABS systems. Inside there's a new instrument cluster, the non-AMG models get new bumpers and flared wheel arches, and there's a bright new array of colors available for the AMG models, which can also be ordered in a new special Edition 463 featuring unique trim inside and out. The revised models will be arriving at US dealers in November, however the diesel model will not be making the transatlantic journey to our shores. The data in the press release below (as well as the images in the gallery above) pertain to the European models, with the correct output figures for the US models amended in the text above.
