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

A Chevy Camaro hybrid? That's what EcoCAR3 could bring

Figuring out a way for a hybrid powertrain to co-exist with the performance expectations of a classic American muscle car is a challenge that could vex that most experienced of automotive engineers. It's a challenge, in fact, being handed to a bunch of college students. Over the next four years, students from 16 North American colleges and universities will attempt to wring fuel efficiency from a 2016 Chevy Camaro as part of EcoCAR3, an advanced-vehicle technology competition sponsored by the Department of Energy, General Motors and others. They'll be attempting to use hybrid or plug-in hybrid technology while not sacrificing the performance of the Camaro, which was selected in part because the current model achieves just 17 miles per gallon in city driving and 28 MPGs on the highway, per EPA numbers. Students will get the latest version of the vehicle to work on, one that is expected to be unveiled next month on Belle Isle in Detroit. "If we still want to produce V8 Camaros, we're going to have to look at alternative methods of propulsion," said Al Oppenheiser, the chief engineer on the Camaro. "So the ideas that these college teams come up with could very easily be adapted to a car like the Camaro." Unlike similar competitions that reward fuel efficiency in vehicles, EcoCAR seeks those gains while emphasizing cost and consumer acceptance of these vehicles. The cars shouldn't look like experiments; they should look like everyday vehicles on the road. Previous competitions have allowed the teams to use whatever powertrain they desired. This time, EcoCAR officials designed the competition to concentrate on hybrid, hybrid-electric and diesel options. Competitors won't have the option of using hydrogen fuel cells as they have in the past. Last year, a team from Colorado State built a vehicle that contained both hydrogen and electric power sources. This year's limit is a curious choice, as some automakers such as Toyota have placed heavy bets on fuel cells in recent years. General Motors also runs a fuel-cell program. With the focus on cost and practicality, however, the program officials wanted to narrow the framework of the contest. "We always have some good decisions on what to make within the scope or out of scope," said Jim Kolhoff, global director of software engineering for General Motors.

2016 Chevy Volt will start at $33,995*

One of the biggest mysteries regarding the 2016 Chevy Volt has been revealed. Chevy announced today that the next-gen plug-in hybrid will have an MSRP of $33,995, which includes GM's $825 destination fee. That's a few hundred dollars less than the current Volt, which has an MSRP of $34,170. The second-gen Volt is about more than a price cut, though. The car has an increased all-electric range (50 miles vs. 38 in the current model) and better fuel economy. Once the battery power runs out – which it doesn't do, in most situations, since 90 percent of all trips are electric-only – the no-longer-premium-only gas engine offers 41 miles per gallon, up from 37 mpg. We know most buyers are price-conscious, and with the still-available federal tax incentive of up to $7,500, the new Volt can be had for $26,495. That should put a spring back into sluggish Volt sales, which are down 46 percent year-over-year so far in 2015. Through the end of April, GM has sold a cumulative 76,136 first-gen Volts since introducing the car in 2010. Chevrolet Announces 2016 Volt Pricing Next Gen delivers more technology at new price as low as $26,495 DETROIT – The Chevrolet Volt is poised to continue to bring new owners to the electric plug-in family. Pricing will be as low as $26,495 after the full federal tax credit of $7,500. (Federal tax credit can range from $0 up to $7,500.) In California, the vehicle's largest market, residents of the state will be able to purchase the all-new Volt for as low as $24,995 after state and Federal incentives. The 2016 model will start at $33,995 MSRP, including an $825 destination fee (excluding tax, title, license and dealer fees). This is almost $1,200 less than the current generation Volt. "The next generation Chevrolet Volt delivers more technology, the ability to drive further between gas fill ups and now with even more value to our customers. It's what our loyal Volt owners told us they wanted," said Steve Majoros, Director, Chevrolet Marketing. "We are confident we will continue to attract new customers to Volt with the vehicle's product improvements and attractive price." The Volt continues to be a success with the brand with nearly 70 percent of Volt owners trading in a non-GM product or adding to their household fleet in 2014, the highest of any Chevy nameplate. The number one trade-in for the Volt is the Toyota Prius. To date more than 75,000 first generation Volt owners have driven hundreds of millions of EV miles.
