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

Online Find Of The Day: 2008 Cadillac XLR picks up where Excalibur left off

We try very, very hard to keep snark away from creations like the one you see here. After all, someone poured plenty of enthusiasm, time and money into turning a 2008 Cadillac XLR into a modern interpretation of the new-old cars typically done by cottage builders like Excalibur and Clénet. Even so, it's hard not to wince when you set an eye on this machine. With its wheelbase stretched to accommodate the extra bodywork, goofy sidewalls and upkicked nose (examine it in profile, it looks slightly bent in the middle), this "neoclassic" takes whatever was loveable about the Cadillac underneath and buries it in a tacky grave.
Miraculously, the engine bay has been left unmolested, which means the retractable hardtop convertible still features a 4.6-liter Northstar V8 engine good for 320 horsepower. If only that were enough to outrun its shame. If, for some reason, you feel like taking this thing home, Harry Kaufmann Motorcars of Milwaukee says it can be yours for a paltry $74,998. We wish were joking. Check it out here.

Comparing Cadillac's crazy classy coupes

I just returned from the press launch of Cadillac's new ATS-V, a high-performance version of the US luxury marque's entry-level compact car. While ordinary ATVs offer a choice of a 202-horspower, 4-cylinder, a 272-hp turbocharged four or a 321-hp V-6, this one packs a twin-turbo V-6 that pumps out 464 thoroughbred horses and 445 pound-feet of hard-charging torque. Starting at $62,000 for the sedan and $64,000 for the sexy coupe, ATS-Vs are available with a 6-speed manual (with Active Rev Matching and no-lift shift capability) or an 8-speed automatic with steering-wheel shift paddles. They comes with GM's latest 4-mode Magnetic Ride Control, 5-mode Performance Traction Management (with launch control), competition-spec traction and stability controls, an electronic limited-slip differential, specially-tuned electric power steering, huge Brembo brakes, and added air cooling for their engine, transmission, and rear axle lubricants. They roll on 18-inch Michelin Pilot Super Sport tri-compound summer tires on 9-inch-wide front alloy wheels and 9.5-inch-wide rears. And they will rocket from rest to 60 miles per hour in less than four seconds while delivering 16 city EPA miles per gallon and 24 highway with the automatic and 17/23 with the manual transmission. The obvious purpose of all this technology is to effectively endow Cadillac's latest V-Series models with a rarely achieved true dual personality: go, stop, and corner like race cars on a track, then sooth, coddle, and entertain like luxury cars on the way to and from the track, or work. We had ample opportunity to verify both personalities with multiple hot laps of the Circuit of the Americas (COTA) Grand Prix course, followed by a more leisurely drive on public roads near Austin, TX. Even lacking wheel-to-wheel comparisons, we believe these hot new ATS-Vs are fully competitive with their pricier German competitors, and probably superior in some ways. So now, Cadillac will offer not one but two very sharp-looking, upscale, small-volume, 2016 compact coupes, almost the same size and at similar prices, but with totally different missions: this new high-performance ATS-V and the soon-to-be-upgraded ELR extended-range EV. The key question: why? Aside from its cramped back seat and ridiculous $76,000 starting price, I loved the ELR when it was introduced for 2014.
