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

Stellantis will give its brands 10 years to prove they deserve to live

Formed by the merger of PSA Peugeot-Citroen and Fiat-Chrysler Automobiles, Stellantis has 14 brands under its roof, a number that makes it one of the largest groups in the industry. Rumors claimed not every brand would survive, with Chrysler often earmarked to get axed, but the firm said it will give them all a chance to shine. "We're giving each (brand) a chance, giving each a time window of 10 years and giving funding for 10 years to do a core model strategy. The CEOs need to be clear in brand promise, customers, targets, and brand communications," announced Stellantis boss Carlos Tavares during the Financial Times' Future of the Car event. His comments confirm Chrysler fans and dealers don't need to worry about the future — at least not yet. And, against all odds, Lancia enthusiasts can breathe a sigh of relief, too. Former FCA head Sergio Marchionne warned of the brand's demise on several occasions. Alfa Romeo is safe for now, too, as is Vauxhall, which are basically just Opels sold in the United Kingdom with a different badge. The engagement made by Tavares also means Stellantis won't divest any of its brands to raise capital until at least 2031. It's now up to each executive team to make a case for the brand they run, an unusual survival-of-the-fittest strategy in an era when cutting costs is more common than spending cash. Diving into the vast Stellantis parts bin should help even the most troubled brands turn their fortunes around on a relatively tight budget. It seems likely that survive Chrysler will need to look beyond the 300 and the Pacifica/Voyager, the only models in its range, and completely reinvent its image, which is currently nebulous at best. Lancia, once the champion of luxury, performance, and innovation, faces the same challenge. It's not starting quite from scratch, it's relatively popular in its home country of Italy, but it will need to think globally and expand outside of the city car segment to survive.

MotorWeek remembers a better time for Mitsubishi performance

Dodge still knows how to create an capable performance car – look at the Hellcats, for example – but the same isn't true for Mitsubishi. With the Lancer Evo's demise, we don't expect driving enthusiasts to clamor for any of the Japanese automaker's other products. Things used to be different, though. As MotorWeek found in its new Retro Review, the 1991 Mitsubishi 3000GT VR4 and its sibling, the Dodge Stealth R/T Turbo, were impressive sports coupes in their day. Dodge and Mitsubishi packed a bevy of cutting-edge tech into the coupes. In these trims, both sported all-wheel drive, four-wheel steering, an adjustable suspension, active exhaust, and automatic climate control. The 3000GT VR4 upped the ante even more with active aero parts at the front and rear. Their 3.0-liter twin-turbo V6 was good for 300 horsepower and 307 pound-feet, which were good numbers at the time. This pair put all their gizmos to good use, too. MotorWeek compares the all-wheel-drive system's grip levels to a Porsche 911 Carrera 4. When was the last time you heard any favorable similarity between a Mitsubishi and a Porsche? The Stealth R/T Turbo and 3000GT VR4 came from a special time for Japanese sports coupes, when every brand had a halo model. Whether you were looking at Nissan 300ZX, Mazda RX-7, Toyota Supra, or even the Acura NSX, there was a lot to like on the market. MotorWeek's latest Retro Review offers a great reminder of that period.
