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

How real is the Chevy Bolt EV and will it really cost $30,000?

"This is us bragging that we can do this kind of car." That's how Michael Simcoe, GM's executive director for NA exteriors, described the Chevy Bolt EV concept, which made a surprise appearance at the Detroit Auto Show today. While there was talk of a 2017 production debut, this is for sure a concept vehicle. But that means the ideas behind the vehicle are perhaps more important than the details. For example, no one is talking about what size battery might appear in a production Bolt, but Simcoe would talk about how rapid progress in battery improvements made it possible for GM to make the bold Bolt declaration that promises 200 miles and a price tag of around $30,000 (after incentives). But if the Bolt makes it to market, it won't be until 2017 (as rumored) or later, is it really fair to promote the car as being available with a federal tax credit? For one thing, credits for plug-in vehicles may change in the next few years, but if the laws stay the same, each manufacturer is limited to 200,000 vehicles before the credits start to decline. GM is justifiably proud that it's sold over 70,000 Volts thus far, but with a new model coming out later this year and a few years to go until the Bolt potentially arrives, GM could be pushing right up against that 200,000 limit when the Bolt goes on sale. But Volt executive chief engineer Pam Fletcher told AutoblogGreen that, "We're just trying to take some of the confusion out." "Think about talking to the average consumer," she said. "First, going through the explanation of how the federal tax credit was set up, how it's being used and so on. [In the industry, we] have the luxury of understanding the nuances of that regulation, but right now people who aren't in the marketplace, they don't have the luxury of all that. It's already hard to communicate the details so we gave them data in a way that is what they're used to seeing." There was one question that drove the two-year Bolt gestation and design period, Simcoe said: What does a better battery offer a vehicle designer? "We've got a number of spaces we play in for powertrain technology and obviously electrification is one of them," he said. "With Volt 1 and then the Spark EV, with that development and batteries getting better for us, we started doing some practical packaging to deliver a vehicle which was not the traditional aero form which you see around electric vehicles.

Basic configurator for 2021 Chevy Colorado and GMC Canyon slips online

TFLnow discovered basic configurators for the 2021 Chevrolet Colorado and GMC Canyon are already online at GM's site for employee discounts. These aren't the fully-featured whiz-bang configurators that will show on the retail websites soon, but they include a bunch of the relevant info a shopper would be looking for. After trim changes detailed earlier this year, the 2021 Colorado offers the most choice, even with the two-door base model gone. Cutting the entry-level Colorado also means the entry-level price has gone up by $3,900; the 2020 Colorado could be had for $22,495, but the 2021 model starts at $26,395 after the $1,195 destination charge. That gets you the extended cab with a standard bed in two-wheel drive. The 2WD crew cab with a short bed starts at $28,295, and the 2WD crew cab with a standard bed starts at $30,595. At the top end, the ZR2 model runs $44,395, which is $200 more than the 2020 version. The color palette isn't complete, but the options page shows a number of choices for packages. The Redline Special Edition Package goes up $10 to $2,690, the Tonneau and Step Package increase $100 to $1,195, a new Chrome Package puts shiny stuff in places like the door handles and steps for $300, while the Black Bowtie Emblem Package drops $80 to $140. The one-inch front leveling kit, which was thought to cost $150 based on early order information GM Authority had seen, is here listed for $450 and available on the Colorado but not the Canyon.  The Canyon makes matters a tad simpler by having many options locked in depending on which one starts with — 2WD Elevation Standard starting at $27,595, 2WD Elevation for $31,195, 4WD AT4 with a cloth interior for $39,395 or AT4 with leather for $41,195, the least expensive Denali starting at $42,095 for a crew cab short box with 2WD. The Elevation includes items like the Convenience Package that are options on the base model, and also offers a $1,400 High Elevation Package conferring heated and power black leather seats, plus a heated steering wheel, that can't be optioned on the Elevation Standard. The pinnacle is the crew cab with a standard bed in Denali 4WD trim for $45,895. Colors and many of the final options and accessories, such as the AT4 Off-Road Performance Edition Package we've heard about, are also missing here, but there's heaps to play around with to get an idea of what you'll be in for if you're considering a 2021 Canyon.
