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

Leaked GM document shows GMC Sierra I6 diesel is more powerful than F-150's

GM told us earlier this year that the 2019 GMC Sierra would be getting a 3.0-liter I6 diesel option, but it never mentioned power or fuel economy figures. Hold the phone though, because a leaked GM Canada document just showed up online that lists out the details we've been waiting for. Originally published by TFL Truck, the 3.0-liter oil-burner supposedly makes 282 horsepower and 450 pound-feet of torque. For those who are counting, that's more than the Ford F-150's 250 horsepower and 440 pound-feet from its 3.0-liter diesel. It soundly bests the 240 horsepower and 420 pound-feet of torque from Ram's 3.0-liter diesel as well. Fuel economy is another story, though. The promotional material states that it will get 28 mpg on the highway, which is 2 mpg short of the F-150's 30 mpg — mind you, it's only capable of that magical 30 mpg figure in rear-wheel drive form. There's another caveat here, too; these are numbers for Canada, so they're not exactly finalized EPA figures. However, we wouldn't expect drastic differences between the two when the American numbers come out. The leaked documents also state the diesel Sierra will be capable of towing 7,800 pounds. That number seems remarkably low when compared to the F-150, which can tow up to 11,400 pounds with its diesel. Extra power and torque would have us assume that GM could get even better numbers than Ford, so we're going to hold our final judgment for official word. A 10-speed automatic will do the shifting on the diesel, just like on the 6.2-liter V8. Since the Chevy Silverado is also expected to get this engine, we can assume the figures would be almost, if not identical, to those we see here. We recently drove the 2019 Sierra and Silverado without the diesel engines, so go check those reviews out if you'd like to know more of our thoughts on the redesigned GM trucks. Related video:

Meet Alex Archer, the engineer behind GM's power-sliding center console

In 2009, a GM manager complained to a 59-year-old GM technician about the hassle of retrieving items from a pickup truck bed after driving shifted the cargo. In two days, the tech had come up with the ideas that, ten years later, would debut as the MultiPro tailgate. The engineering teams kept the tailgate secret in part by hiding mock-ups in a locked storage closet in GM's Vehicle Engineering Center in Warren Michigan for two years. A piece in the Detroit Free Press reveals that another storage closet in Warren would play the same role in a different cloak-and-dagger operation, this time for the power-sliding center console in GM's new full-sized SUVs. During a meeting in early 2017, bosses gave the job of the console's creation to 24-year-old design release engineer Alex Archer, just two years out of Stanford University with a degree in engineering and product design.  This time, the catalyst for the feature was an internal GM think tank called co:lab, where employees suggest ideas. Execs gave Archer the task because "They needed someone willing to ask a lot of questions," her 36-month mandate to produce a six-way console that could be a standard cubby or a gaping maw able to swallow four gallon jugs or hide a secret compartment. Clearly, she succeeded. It took Archer and the team nine months to devise a prototype, another six months to get the green light for production. As with the tailgate, the team working on the console grew to include designers, production engineers, and suppliers. Archer, now 26, shepherded the process, and her name is on the patent. "It took a ton of people, I'm just somebody who stuck with it the whole time," she said. GM like her work well enough to produce the "Day in the Life" segment above, five months before the world would hear about the console. Archer's path to engineering was as unlikely as getting the job for the console. She had entered Stanford with plans to be a doctor. But an innovation class during her freshman year, and a sophomore summer spent helping her grandfather rebuild a 1937 MG engine recharted her course. Her grandfather told her, "You know, you could be an engineer for a car company." Consumer reaction to Archer's work won't be far off, the SUVs slated to hit dealerships soon. Meanwhile, she's busy on something that could be just as intense as the console: Restoring a 1955 Packard Clipper in her garage. Head to Freep to check out the story of Archer and the console.
