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

2015 Chevrolet Corvette Z06 [w/videos]

I think I was supposed to be back hours ago. Driving northwest on State Road 190 with a final destination deep in the heart of the Death Valley National Park, it occurs to me that I might have agreed to return after an hour or so, instead of the four I'll end up stealing, solo, in the new Z06. Somewhere in the combination of mountain vistas, arching, speed-hungry desert roads, and the sound of this titanic engine on a constant run up the rev ladder, I forgot everything I'd promised back at home base. The generous, civilized part of me worries for a moment that absconding with the new-best Corvette might have left one of my fellow journalists without a car. But the selfish part of me – the part largely in control of the rocket-launcher of a throttle under my right foot ­– says "screw it." I spent two days with the 2015 Chevy Corvette Z06, a monster of a sports car that will soon be dominating track days everywhere, and I never once was inclined to share it. Hurtling through the shattered stillness of the desert and pulling big Gs at Spring Mountain circuit, I never felt overly disposed to give up my seat. This Corvette, more than any I've yet driven, was deep enough to hold my attention; for two days, for two years, probably. With this Z06, the Corvette steps over the amazing-for-the-price category, and solidly into the best-cars-in-the-world zone. There are peripheral elements that remind me of its blue collar, Bowtie heritage, sure, but there's more that simply begs me to carry on driving... faster. Most casual car observers will be able to pick the 2015 Z06 out from its less aggressive Stingray brothers. Subtler hints include a new, more open grille, larger extractor on the taller hood and rather discreet badges on the flanks of the car. More outrageous is the finned spoiler on the rear trunk lid, and the widebody look offered from flared fenders – an extra 1.57 inches (40 millimeters) at their beefiest point. Even driving around performance-car-laden Pahrump, NV – loaded thanks to the very active community at the Spring Mountain racing resort – members of the local populace were turning heads, waving and generally noting the Z06 with approval when I drove through town. In Torch Red over black painted aluminum wheels, staggered at 19-inches in front and 20 at the back, the amped-up Z06 hits a new level of road presence for the C7.

Impala SS vs. Marauder: Recalling Detroit’s muscle sedans 

Impala SS vs. Marauder — it was comparo that only really happened in theory. ChevyÂ’s muscle sedan ran from 1994-96, while MercuryÂ’s answer arrived in 2003 and only lasted until 2004. TheyÂ’re linked inextricably, as there were few options for powerful American sedans during that milquetoast period for enthusiasts. The debate was reignited recently among Autoblog editors when a pristine 1996 Chevy Impala SS with just 2,173 miles on the odometer hit the market on Bring a Trailer. Most of the staff favored the Impala for its sinister looks and said that it lived up to its billing as a legit muscle car. Nearly two-thirds of you agree. We ran an unscientific Twitter poll that generated 851 votes, 63.9 percent of which backed the Impala. Muscle sedans, take your pick: — Greg Migliore (@GregMigliore) April 14, 2020 Then and now enthusiasts felt the Impala was a more complete execution with guts. The Marauder, despite coming along later, felt more hacked together, according to prevailing sentiments. Why? On purpose and on paper theyÂ’re similar. The ImpalaÂ’s 5.7-liter LT1 V8 making 260 horsepower and 330 pound-feet of torque was impressive for a two-ton sedan in the mid-Â’90s. The Marauder was actually more powerful — its 4.6-liter V8 was rated at 302 hp and 318 lb-ft. The ImpalaÂ’s engine was also used in the C4 Corvette. The MarauderÂ’s mill was shared with the Mustang Mach 1. You can see why they resonated so deeply with Boomers longing for a bygone era and also captured the attention of coming-of-age Gen Xers. Car and DriverÂ’s staff gave the Marauder a lukewarm review back in ‘03, citing its solid handling and features, yet knocking the sedan for being slow off the line. In a Hemmings article appropriately called “Autopsy” from 2004, the ImpalaÂ’s stronger low-end torque and smooth shifting transmission earned praise, separating it from the more sluggish Mercury. All of this was captured in the carsÂ’ acceleration times, highlighting metrically the differences in their character. The Impala hit 60 miles per hour in 6.5 seconds, while the Marauder was a half-second slower, according to C/D testing. Other sites have them closer together, which reinforces the premise it really was the little things that separated these muscle cars. Both made the most of their genetics, riding on ancient platforms (FordÂ’s Panther and General MotorsÂ’ B-body) that preceded these cars by decades. Both had iconic names.
