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

Next-gen Chevy Volt will get 1.5-liter, four-cylinder engine

As General Motors gets ready to unveil the new Chevy Volt at the Detroit Auto Show in January, it's starting to reveal a few more details about the updated plug-in hybrid. Today should be fruitful on that front, thanks to an event GM is hosting today that focuses on the new Volt, and we've just had the first bit of new: a bigger engine is coming. Since the beginning, the Volt has used a 1.4-liter, four-cylinder engine as a range extender when the battery runs dry. The second-generation model will instead get a slightly larger 1.5-liter, four-cylinder engine that will be built in Flint, MI. That's a step up from the various engines that have been a part of the 2016 Volt's rumored mills, everything from a 1.0-liter or 1.2-liter three-cylinder to a 2.0-liter turbo. The confirmation about the new 1.5-liter powerplant was found in Automotive News, where we also heard again that GM is going to start building the new Volt's electric drive unit in Detroit, moving production up from Mexico. We will have more information on the 2016 Chevy Volt later today.

2016 Chevy Volt ads strike frustrating, yet familiar, chord

Sometimes, it's hard to let go. In the six years that GM has been advertising and selling the Chevy Volt, one dominant message is that the car is an EV without any range anxiety. On the one hand, this is a positive thing: our car does something that other electric vehicles don't. Of course, there's another, more reasonable take on the message that EVs only equal limited range: don't promote this viewpoint if you ever plan on selling a pure EV. But, of course, this is exactly what GM is doing with a new ad for the 2016 Chevy Volt. Called Elevator, the spot (watch it above) compares driving an all-electric car with riding in an elevator getting stuck. Your Nissan Leaf might run out of electricity, the ad says, and that would be as uncomfortable as being trapped between floors. The main problem, of course, is that Chevy also offers the Spark EV and is getting ready to sell the Bolt EV. Does the company think that everyone will forget these anti-EV commercials when it come time to shop for a Bolt? Even worse, does GM think we've forgotten the Anthem ad for the Volt back in 2010? Apparently, so. Elevator isn't the only ad for the 2016 Volt that GM debuted today. The other, called Time Capsule (below), takes a swipe at the Toyota Prius. Trouble is, there are two easy ways to dismiss this ad as well. First, and most obviously, if GM is against using old technology, then why does it continue to shove a 100-year-old fossil fuel engine into almost every car it builds? Second, attacking the Prius for using 15-year-old tech – when said tech is still able to mop the floor with any hybrid from GM in the fuel economy race - is more like an admission of defeat than anything to be proud of. "Hey look, the Prius uses technology from the '90s," GM says. To which the observant viewer will ask, "Well, then why can't you build a 50-mile-per-gallon hybrid, GM?" It's also worth noting that Chevy has been on a misguided advertising streak as of late. We bashed their ads that suggested its Silverado is better than the F-150 because it uses steel instead of aluminum, too, especially since those commercials used shark cages and stupid superhero costumes in an attempt to make a point. Chevy, stop assuming we're all idiots. Please. Now, the 2016 Volt is a great car and I know that GM can make a darn good Volt ad (like this one), so seeing the company shoot solid fuel-efficient technologies in the back (again and again) is just frustrating.
