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

AEV Jeep Wrangler Unlimited Rubicon

After their rented 2007 Hummer H3 failed them during the brutal Rallye Aicha des Gazelles in Morocco, Amy Lerner and her sister Tricia Reina were on a quest to find the most capable production off-roader for their next competition - they chose a 2012 Jeep Wrangler Unlimited Rubicon. Their next mission was to find a company with the competence to configure it to win. After poring over Internet forums and perusing countless magazines for an outfitter who could meet their demanding requirements, they sent their bright orange JK ("Crush" is the official color) to American Expedition Vehicles (AEV) for some modifications.
The Michigan-based team at AEV kept the Jeep's 3.6-liter V6 and automatic transmission stock, but replaced the hood with a tall AEV Heat Reduction Hood and added an AEV Snorkel Kit for water crossings (it serves double-duty as its raised height helps to keep the air intake out of the kicked-up dust on the trail). Front and rear off-road bumpers were bolted in place, and AEV skid plates were added to provide additional undercarriage protection. A pair of IPF-900 off-road lights improve visibility, while a 10.2-gallon AEV Fuel Caddy (located behind the exterior spare) added some range. The suspension was upgraded with a 3.5-inch lift kit with Bilstein remote reservoir shocks, and 35-inch Falken Wildpeak A/T tires (LT285/70R17) were mounted at all four corners on AEV's beadlock wheels.

Jeep Cherokee won't get diesel until sales of oil-burning Grand Cherokee improve

Okay Jeep fans, you want more diesel options? Time to step up and prove it. The only way Jeep will offer a diesel powerplant in the Cherokee, according to brand head Mike Manley, is if sales of the Grand Cherokee EcoDiesel nearly double.
Currently, about eight percent of the Grand Cherokees sold feature the 3.0-liter, EcoDiesel V6. That's simply not enough to warrant the bringing an oil-burning Cherokee to the US market, despite the vehicle's presence in Europe, where it's sold with a 2.8-liter diesel V6.
"Cherokee is slightly different because of its weight and size. When I think about bringing Cherokee diesel here, I would like to see Grand Cherokee diesel get much higher than eight percent," Manley told Automotive News. "It would have to be in mid-double digits."
