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

Recharge Wrap-up: Custom Nissan Leaf video, Shell's Arctic oil plans

A video shows a customized Nissan Leaf. An owner in Japan slapped a pretty spiffy body kit on his EV, along with some Forgiato custom wheels and brakes. There's no telling what effects these modifications have on the car's aerodynamics or driving range, but it definitely gives the leaf a unique and sporty look. Check it out in the video above, and read more at Ecomento. Shell has big plans to drill for oil in the Arctic Ocean. With 13 percent of the world's undiscovered oil resting beneath those frigid waters, the company sees this new frontier as promising, despite the challenges involved in exploiting it. So far, Shell has spent $7 billion on Arctic operations without having extracted any oil yet. Of course, the idea of Arctic drilling has loads of opposition from concerned individual and organizations concerned with the environmental hazards of extracting oil in the icy north. Read in-depth about Shell's plans at Bloomberg. Ford has won the Altair Enlighten Award for its lightweight technology in the F-150. The award program honors automotive innovations in weight reduction. Ford was recognized for shaving 700 pounds off of the F-150 while improving performance and safety. "It's encouraging to see Ford implementing a holistic lightweighting strategy, which resulted in impressive weight savings that were incredibly significant to the judging panel," says Altair's Vice President of Global Automotive, Dave Mason. General Motors was the runner-up, with its weight savings in the Cadillac ATS and CTS. Read more at PitchEngine. The Diesel Technology Forum has outlined environmental improvements in heavy-duty vehicles at a rulemaking hearing in front of the EPA and NHTSA. Between 2010 and 2014, clean diesel technology reduced carbon emissions equal to that of 2.4 coal-fired power plants, and NOx emissions equal to 158 coal plants. New rules would help further improve the environmental performance of diesel engines. "Advances in diesel engine technology will continue to contribute to the overall efficiency gains of vehicles under this proposed rule," says Diesel Technology Forum Executive Director Allen Schaeffer. "As a result we expect diesel technology to remain the primary power-plant for commercial trucks into the foreseeable future." Read more in the press release below.

2016 Ford Shelby Mustang GT350R First Ride

Ford Performance Chief Engineer Jamal Hameedi was in China when he received an interesting text. Half a world away his team was shaking down the newest Shelby Mustang at Grattan Raceway in rural Michigan. The news was encouraging. The GT350R was keeping pace with a Porsche 911 GT3, even nosing ahead of it during time trials, while the GT350 was running about even with a 911 Carrera S and a Chevy Corvette Stingray. "That was a good text to get," he recounted a week later as we chatted alongside the track at Grattan. On this scorching summer day, there were no Porsches or Stingrays to be found, but we've come to preview the track-focused GT350R. Ford drivers are at the wheel, and we're riding shotgun. After several hot laps, we're left with a predictable observation: The GT350R is wicked fast and quick as hell. Much of this is thanks to the 5.2-liter flat-plane crank V8 that pumps out 526 horsepower and 429 pound-feet of torque. It's the most powerful naturally aspirated road-legal engine in Ford's 112-year history. To help the engineering process, Ford bought a Ferrari 458 Italia and ripped apart its V8. The GT350's engine ended up being 10 pounds lighter. For the coup d'grace, Ford's mill also revs to a Ferrari-like 8,250 rpm. As formidable as all of that looks on paper, it sounds even more imposing in real life (see the related video below). The engine in our GT350R crackles, growls, and opens up to a flat-out roar as we explode onto the track, gripping the door pulls to calm our nerves. Grattan is a challenging, twisty course. The corners are tight, and the elevation changes quickly. At one point, our test driver aggressively tackles a curve and we're briefly airborne. During the first stint, we reach about 140 miles per hour. But the GT350R isn't about straight-line speed or pure power. It's designed to get around a track as rapidly as possible. That means Ford took the 'base' GT350 – which should be more than at home on the track itself – and re-tuned the suspension and aerodynamics. There's a larger front splitter and rear carbon-fiber spoiler. The 19-inch carbon-fiber wheels are stiffer and lighter than comparable aluminum rollers, and they're wrapped in Michelin Pilot Sport Cup 2 high performance rubber. Additionally, Ford ripped out the back seats, air conditioning, trunk floorboard, stereo, backup camera, and anything else that wasn't necessary.
