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

Mercedes raises the roof on new CLA Shooting Brake [UPDATE]

UPDATE: As we feared, the CLA Shooting Brake is not currently slated for US availability. The text below has been adjusted accordingly. Of all the variants in Mercedes' smallest line, only one doesn't have a liftgate, and that's the CLA-Class. But don't worry, the German automaker is out to fix that too with the reveal of the new CLA Shooting Brake you see here. Based on the same platform that underpins the CLA four-door coupe, the A-Class hatchback, B-Class minivan and GLA crossover, the new Shooting Brake applies a similar formula we've already seen on the bigger CLS Shooting Brake but in a much smaller form – which is to say, it's a wagon, but a shapely one. The revised roofline means more headroom in the back seat and significantly more cargo capacity than the four-door's trunk. Mercedes will offer the CLA with a variety of engine choices, including a 2.1-liter turbodiesel with either 136 or 177 horsepower, a 1.6-liter four with 122, 156 or 211 horsepower. That last model will even be available with 4Matic all-wheel drive for those not enamored by the idea of a front-drive Benz, but the top of the range, of course, is the CLA45 AMG Shooting Brake that carries the same 2.0-liter turbo four – all 360 horsepower of it – as the four-door CLA45 as well as the A45 and GLA45. Driving once again to all four wheels, Daimler says it'll reach 62 in 4.7 seconds (even quicker than the crossover) and top out at the usual 155 miles per hour. Of course those options only apply to markets where the new Shooting Brake will be offered. And unfortunately, Mercedes-Benz USA confirmed to Autoblog that (like the CLS wagon) the CLA Shooting Brake won't be making the transatlantic voyage to US showrooms (where the E-Class is the only low-slung Benz wagon on offer). That leaves the four-door CLA and the GLA crossover still holding down the pint-sized fort for Mercedes. THE NEW MERCEDES-BENZ CLA SHOOTING BRAKE: SPACE FOR SOMETHING NEW Stuttgart. Breathtakingly sporty proportions and a powerfully dynamic design idiom with sensuously shaped surfaces already made the CLA unmistakable in its four-door Coupe guise. It is now followed by a further design icon, the CLA Shooting Brake, with a unique look all of its own. The lower overall height and the elongated coupe-style roof contour line, the low greenhouse and the sweep of the high beltline are the key design features of its distinctive profile.

Mercedes-AMG considering turbo fours, hybrid sixes for future performance sedans

Think of the letters AMG and you'll probably end up picturing a performance sedan with a big V8. Such has become, after all, the Mercedes turning division's calling card. But with the introduction of its 2.0-liter turbo four, AMG is working at turning that notion on its head.
The highly potent engine produces 355 horsepower and is presently installed in the A45 AMG hatchback, CLA45 AMG sedan and GLA45 AMG crossover, giving Benz's smallest family a full range of performance models. But that might not be the full extent of the high-strung four-pot's use.
Speaking with AMG boss Tobias Moers, Britain's What Car? magazine reports that Affalterbach is considering slotting the same engine into larger models, particularly performance sedans like the C-Class. As we recently reported, Mercedes is already preparing to up the power from the turbo V6 in the C400 to slot a C450 Sport in below the C63 AMG. The C450 is expected to offer around 367 horsepower where the CLA45 AMG et al pack 355, but the lighter weight of the four-cylinder engine would likely offset the truancy of those extra dozen horses. Of course such a prospect would be much further down the pipeline than the C450 Sport which is expected to arrive much sooner.
