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

Ford Shelby GT350 Mustang is a lean, mean, Z/28-fighting machine [w/video]

If there's one thing you can count on, it's that the renewed rivalry between the Ford Mustang and Chevrolet Camaro will never, ever cease. For every version of Ford's pony car, there's an equally potent Chevrolet. And so with the debut of the Camaro Z/28 earlier this year, Ford has responded with a track-focused 'Stang of its own, resurrecting the Shelby GT350 name.
It looks to be a fine piece of work, this Mustang, with power coming from a naturally aspirated 5.2-liter V8 that will produce "more than 500 horsepower" and "above 400" pound-feet of torque. That grunt runs to the rear wheels via a six-speed manual transmission, and a Torsen limited-slip differential keeps everything in line.
But that's hardly the most impressive piece of the GT350 puzzle. Ford has increased the Mustang GT's chassis stiffness for duty here in the Shelby, and the coupe employs MagneRide damping which automatically adjusts based on road conditions and driver inputs. It's a first both for the Blue Oval and for the segment. And speaking of firsts, the GT350 uses a flat-plane crankshaft - something Ford has never included in a production V8 before.

All the details on Plug In 2014 electric vehicle conference you could ever want

One of the best parts of the Plug In 2014 Conference in San Jose, CA last week was getting to listen in on thoughts about the state of the plug-in vehicle industry from people who have been involved with it for ages. They bristle when you call them the "Old Guard" (learned that one the hard way), but these are the people who have been through a number of ups and downs with plug-in vehicles, so they've got what we call perspective. Their knowledge was on full display in the three plenary sessions, which the Plug In Conference organizers have given us permission to share with you. Each is at least 90 minutes long, so make sure to set some time aside to enjoy the discussions after you download them (any help with making them streamable would be appreciated). Follow us below to see what we've got to offer. Opening Plenary (audio link). "The Road Ahead – Delivering on a Vision for Sustainable Transportation." Moderated by Mark Duvall (director of energy utilization at EPRI, the Electric Power Research Institute, and a long-time EV advocate), this panel featured: Jack Broadbent, Executive Officer / APCO, Bay Area Air Quality Management District Pat Romano, President & Chief Executive Officer, ChargePoint, Inc. Aaron Johnson, Senior Director, Customer Programs, Pacific Gas and Electric Company Brendan Jones, Director, EV Sales Operations & Infrastructure Deployment, Nissan North America, Inc. David W. Cash, Commissioner, MassDEP Dan Sperling, Director, Institute of Transportation Studies, University of California, Davis Highlights: Educating drivers to "get over the gas station" is a key strategy, how Level 2 and DC Fast Charging are really "a new paradigm," that there have been well over 214,000 EVs sold in US as of July 2014 and where Nissan sees huge potential for more EV sales (Northeast US and medium-size cities like St. Louis and Pittsburgh). Wednesday Morning Plenary (audio link). "Getting to the Mass Market – A Discussion of Ideas for Widespread PEV Adoption." Moderated by John Gartner, research director for smart transportation at Navigant Research.
