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

Ram reveals 2014 truck lineup, EcoDiesel V6 a $2,850 option on 1500 models

The fullsize pickup truck market is as competitive now as it's ever been, and with Ford's F-Series line leading the way in sales, GM's Chevrolet Silverado and GMC Sierra twins boasting brand-new designs, you knew Ram wasn't about to rest on its laurels for the 2014 model year.
And so we present to you the 2014 Ram lineup, with the biggest change being the addition of an optional 3.0-liter EcoDiesel engine for the 1500 model (the same powerplant that's gotten rave reviews in the latest Jeep Grand Cherokee) and the proliferation of the eight-speed TorqueFlite transmission across the entire model range. That engine boasts 420 pound-feet of torque to go along with its 240 horsepower, which means it ought to be able to tow just about anything the 5.7-liter Hemi can, while returning significantly better fuel mileage. Sadly, Ram has not yet released official estimated mpg figures, though it is claiming best-in-class results (though there aren't any other light-duty diesel pickups to compare against).
Standard on Ram 1500 is the Pentastar V6 engine that was introduced for the 2013 model year, pushing 305 horsepower and 269 lb-ft of torque, and the Hemi V8 is optionally available with 395 horsepower and 410 lb-ft of torque. All engines are mated to the eight-speed automatic. The previously available 4.7-liter V8 has been dropped for 2014.

Ram 1500 EcoDiesel HFE ekes out another mpg, creeps toward 30

The idea of a fullsize pickup knocking on 30-miles-per-gallon highway was impressive last year when Ram announced its 28-mpg figure for the Ram 1500 EcoDiesel. For 2015, the company has figured out how to nudge that number up slightly higher for a new HFE version of the diesel model. The mileage tops the segment and beats the nearest competitor by 12 percent, according to the truckmaker. The 1500 EcoDiesel HFE bumps up the standard version's economy numbers by one mpg across the board for an impressive EPA rating of 29 mpg highway, 21 mpg city and 24 mpg combined. The special model is based around the Quad Cab body with rear-wheel drive and a six-foot, four-inch bed and mixes features from the Trademan and Express trims, including optional body-color bumpers. The right combination of 20-inch wheels, side steps and a tri-fold tonneau cover provides the formula to improve the aerodynamics and increase mileage. Mechanically, the truck has been left alone with the 3.0-liter diesel V6 still making 240 horsepower and 420 pound-feet of torque and routing through an eight-speed automatic gearbox. Like gasoline, diesel fuel prices have been on the decline in recent weeks, though the fuel still runs significantly more per gallon than gas. It's intriguing to see Ram going after buyers who hope to eke the best economy from their trucks. The EcoDiesel HFE will go on sale late in the first quarter of 2015, and brand spokesperson Nick Cappa tells Autoblog pricing will be announced soon. Check out a video of Ram CEO Robert Hegbloom unveiling the this fuel-sipping pickup at the 2015 Detroit Auto Show and read the official announcement below. This content is hosted by a third party.
