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

Brabus 800 Roadster is a power-mad aristocrat

If we're being completely honest, we haven't exactly been in love with the aesthetics of the sixth-generation Mercedes-Benz SL-Class. It's mostly a front-end issue, with its glowering eagle-eye headlamps and upright, dinner-plate-sized Three-Pointed Star coming across to us as overwrought. That's particularly troublesome for a roadster whose history has of the most elegant designs of all time in its back catalog. Somehow, the new R231 generation's brash visuals seem more at home on this Brabus 800 Roadster to us.
That's probably because the high-dollar German tuner has turned up the wick on the SL's visuals even further, with carbon fiber bodywork, a more aggressive aero kit, matte hood scoop and complex two-finish wheels. It's all-the-way committed to its brashness, in other words - and justifiably so. Anything with 800 horsepower and 1,047 pound-feet of torque has earned the right to look however it wants, right?
Brabus started with the SL65 and its not-exactly-underpowered 6.0-liter twin-turbo V12, and went to town, fitting their own turbocharger and intercooler system, along with a less-restrictive exhaust system with driver-selectable sound levels and new engine electronics. The result is a 3.7-second 0-62 mph time, an electronically limited top whack of 217 mph... and one seriously compromised toupée.

8 cars we're most looking forward to driving in 2015

Now that 2014 is officially in the books, it's time to look ahead. And following our list of the cars we liked best last year, we're now setting our sights at the hot new metal that's coming our way in 2015. Some of these, we've already seen. And some are still set to debut during the 2015 auto show season. But these are the machines that keep us going – the things on the horizon that we're particularly stoked to drive, and drive hard. Jeep Renegade Not the Chevrolet Corvette Z06. Not the Ford Mustang GT350. Not the new John Cooper Works Mini. Nope, I'm looking forward to the adorable, trail-rated Jeep Renegade. And that's because I really, really, really like our long-term Jeep Cherokee Trailhawk. I do not, however, care too much for the Cherokee's looks, and I really don't like its $38,059 price tag. The Renegade Trailhawk, meanwhile, promises much of the same rough-and-tumble character as its big brother, but at what we expect will be a more reasonable price (I'm personally wagering on the baby Jeep's off-road model starting at no more than $23,000). With a 2.4-liter four-cylinder and a nine-speed automatic, it should also be a bit easier to fill than the V6-powered Cherokee. Also, I can't help but love the way the Renegade looks. It's like someone took a Wrangler, squished it by 50 percent and then handed it off to George Clinton for a healthy dose of funk. The interior, with its bright, expressive trims and color schemes should also be a really nice place to spend some time. I'll be attending the Renegade's launch later this month, so I'll have a much shorter wait than my colleagues. Here's hoping the baby Jeep lives up to my expectations. – Brandon Turkus Associate Editor Mazda MX-5 Miata Here's an uncomfortable truth: I'd rather spend a day driving a properly sorted Mazda MX-5 Miata of any generation on a winding road than I would nearly any other vehicle, regardless of power, price or prestige. It's not just that I prize top-down driving and enjoy the Miata's small size because it gives me more road to play with. I just find there's more motoring joy to be had with high-fidelity handling and an uncorrupted car-to-driver communication loop than I do with face-distorting power or grip – let alone valet-stand gravitas. But perhaps most of all, I love Miatas because they can deliver that level of feedback and driver reward at modest speeds that won't put the locals on edge or endanger lives – you can use more of the car more of the time.
