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

Junkyard Gem: 1983 Cadillac Cimarron

Ah, the Cadillac Cimarron. Conceived during a time when oil prices were zooming upward and smallish luxury imports such as the Datsun 810 and BMW 320i were stealing Detroit's customers, the idea of a fuel-efficient compact Cadillac made sense. Unfortunately for GM, the Cimarron was an image-tarnishing disaster. Here's a fairly well-preserved '83 that I spotted in a Phoenix self-service wrecking yard. In the words of Pulitzer-winning Dan Neil in his 50 Worst Cars of All Time: "Everything that was wrong, venal, lazy and mendacious about GM in the 1980s was crystallized in this flagrant insult to the good name and fine customers of Cadillac." The Cimarron was a Chevrolet Cavalier with a bit of added bling and a fatter price tag. The Chevrolet Nova-based Cadillac Seville had sold pretty well during the late 1970s, so there was precedent for a small, Chevy-based Cadillac. The hood latch mechanism was broken (of course), so I couldn't shoot any photos of this car's 2.0-liter pushrod four-cylinder engine, rated at 86 horsepower. Here's a GM-produced documentary touting the futuristic design of the '83 Cimarron. The Cimarron Dream.

Cadillac to expand V-Series but discontinue CTS-V and ATS-V

Cadillac said Tuesday it will expand its V-Series performance sub-brand with the arrival of the CT6-V sedan in 2019 ( formerly known as the CT6 V-Sport), with plans to add high-performance variants across its portfolio. The flipside to that expansion is the sunsetting of its two existing V-Series performance cars, the ATS-V (both coupe and convertible) and CTS-V sedan. Two new unspecified sedans will slot below the CT6 in Cadillac's lineup, a spokesman said. The CT6-V will arrive next spring, roughly a year after it bowed at the New York auto show. It will feature Cadillac's new "Blackwing" V8, a twin-turbo engine that displaces 4.2 liters and produces an estimated 550 horsepower and 627 pound-feet of torque, sending it through GM's new 10-speed automatic transmission to drive all four wheels. A less-aggressive version of the engine will also appear in the CT6 Platinum model, offering 500 horsepower and 553 lb-ft of torque. "Beginning with the debut of the CTS-V Sedan in 2004, the V-Series sub-brand sparked new life into Cadillac," Mark Reuss, executive vice president and president of GM Global Automotive Group and Cadillac, said in a statement. "As a result of the overwhelming response the CT6 V-Sport received when revealed in early 2018, we've decided to formally make it a V-Series, signaling the expansion of V-Series." View 61 Photos A Cadillac spokesman tells Autoblog the 2019 model year will be the last for the ATS-V and CTS-V. The ATS-V is powered by a twin-turbo 3.6-liter V6 that's good for 464 hp and 445 lb-ft of torque, an increase of 262 hp and 173 lb-ft from the base, four-cylinder ATS, which is also set to go to pasture at the end of the 2018 model year. The CTS-V, meanwhile, boasts a 6.2-liter supercharged V8 under its carbon-fiber hood that puts out 640 horsepower and 630 pound-feet of torque, good for a 3.7-second 0-60 mph time and a top speed of 200 mph. In a Quick Spin review last year, Autoblog Editor-in-Chief Greg Migliore called the car "old-school muscle in an Esquire-approved suit. It's 'roids and cufflinks." As for what's next for an expanded V-Series, Cadillac has the new XT4 crossover, and already other companies are banking on performance versions of crossovers. Cadillac's also developing a less expensive luxury sports sedan called the CT5. It's also said to be planning a production version of the Escala concept starting in late 2021, so those could be possibilities.
