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

Chevy working on production Impala Midnight Edition

To put together the Impala Blackout concept for SEMA, Chevrolet didn't need to go much further than its accessories catalog. The in-house connection is what could make it possible for Chevy to get a production version of the Blackout into dealers this model year, with its few bits of chrome trim and dark detailing on the 19-inch aluminum wheels set into an abyss of gloss black paint, black Bowtie, grille surround, rear spoiler and mirror caps. The interior is black leather, with stainless steel for the sill plates and pedals, and an 11-speaker Bose audio system, and it gets the optional 305-horsepower, 3.6-liter V6. The brand's marketing director for cars and crossovers, Steve Majoros, told Edmunds that it could come in late spring, and that it will be called "Midnight Edition." Majoros didn't give any indication of pricing or if the production car will be spec'd out like the concept. If you simply don't want to wait for late spring, you could work your DIY mojo by putting one together the same way Chevrolet did: give the accessories catalog a workout. Related Video:

Junkyard Gem: 2005 Chevrolet Aveo LS Sedan

The story of Daewoo in North America took some interesting plot turns over the decades. First we had the 1988-1993 Pontiac LeMans, a rebadged Daewoo LeMans. A bit later, Daewoo began selling cars under its own nameplate here, with the Lanos, Nubira, and Leganza available for the 1999-2002 model years. Then Daewoo fled the continent and left warranty service of those cars in the hands of Manny, Moe, and Jack. With GM taking over Daewoo Motors after Daewoo's bankruptcy, we got some Daewoos with Suzuki badges here— the Verona and the Reno— while Chevrolet began selling the South Korean-built Daewoo Kalos as the Aveo for the 2004 model year. This car may not be a gem in the sense that you would want to own one, but it's a gem of automotive history and thus deserves its place in this series (especially because it's one of the rare 5-speed cars sold here). Many (maybe even most) of these cars ended up in the hands of rental-car companies and other fleet users, but we can tell from the three-pedal setup that this car went to a non-fleet buyer. We've had a couple of these cars compete in the 24 Hours of Lemons, where I work as a dignified and respected race official, and they've been amazingly quick on a road course in the hands of good drivers. Power came from this 103-horsepower Opel-designed four displacing 1.6 liters. The Nubira and Lanos got versions of this engine on these shores, too. The LS was the top trim level for the Aveo in 2004, so this car got air conditioning and a halfway decent audio system (by 2004 standards). The seat fabric is industrial-grade stuff, which would have held up well under the steady drip and/or torrents of bodily fluids coating the interiors of rental cars. The 2004 Aveo LS started at $12,045, which comes to about $16,675 in 2020 dollars, so it was a lot of commuter-appliance for the price. The following generation of this car became the Chevrolet Sonic, beginning with the 2012 model year. You can still buy a new Sonic, and the inflation-adjusted price is nearly identical to that of the original AveoÂ… though you might want to move fast if you really want one, because Daewoo stopped selling the Kalos in South Korea not long ago. If you want the rarest member of the Aveo family available in North America, find yourself a hen's-teeth Pontiac G3, the short-lived Pontiac-badged version. Speaking of the G3, here's the way it broke the hearts of gas pumps around the world.
