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

Rest of 2015.5 Dodge Viper lineup available after MSRP drop spurs sales uptick

The Dodge Viper has muscled its way back into buyers' good graces thanks to a $15,000 price drop across-the-board – and we're sure the extra five horsepower didn't hurt, either – posting a 26-percent year-to-date surge after the September realignment. No longer, uh, snakebitten, Dodge is now allowing dealers to place already-sold orders of the TA 2.0 Special Edition and GTS, both of which come with more goodies as standard than on the 2014 models they replace. The $101,995 TA wears a high performance Aero Package consisting of front lower dive planes, front splitter, competition rear spoiler, a dual-mode suspension supporting 18- or 19-inch matte black wheels on Pirelli PZero Corsa tires, two-piece Brembos rotors with black and orange calipers and performance pads, and a five-mode electronic stability control. We'll pretend to ignore features like a "rear carbon fiber applique" on a hardcore V10 sports car. The $107,995 GTS trim throws in Laguna leather seats as standard, an Alcantara headliner and an 18-speaker Harman Kardon system. It will also be the only model that can be had in Ceramic Blue with black stripes, orange brake calipers and GTS gloss black badging. And that rear carbon fiber applique, since it's apparently quite popular. The Connor Avenue plant where workers assemble the Viper by hand will begin production of the TA and GTS in November, the two models will appear in showrooms in Q1 of next year. A press release below has more information. Finally, it appears the only thing Connor Avenue builders looks like it finally has the work to keep everyone at work. {C} New 2015.5 Dodge Viper GTS and TA 2.0 Special Edition Models Now Available for Customer "Sold Orders" With New Pricing and More Content - Dodge Viper sales up 26 percent year-to-date since Dodge repositioned the hand-built exotic in September and reduced the starting price $15,000 - 2015 Dodge Viper's starting U.S. Manufacturer's Suggested Retail Price (MSRP) is $84,995 (all prices exclude gas guzzler tax and destination) - New 2015.5 Viper GTS and TA 2.0 models now available for sold customer orders - Track-ready Viper TA 2.0 Special Edition builds on success of TA model; U.S. MSRP starts at $101,995 and adds high-performance Aero Package, competition rear spoiler and front lower dive planes for increased downforce and improved handling on the track - U.S.

Chrysler almost smothered the Hellcat before it lived

Chrysler's 6.2-liter supercharged Hellcat V8 was an absolute sensation from the very moment it was announced, and honestly, how could it not have been? Packing 707 horsepower and 650 pound-feet of torque, its numbers immediately put every other production muscle car (and many supercars) to shame. Plus, we soon learned that would be wrapped in a package retailing for around $60,000 - a pittance compared to other vehicles offering similar grunt. However, the Hellcat almost never got the chance to rumble under the hood of the Challenger and Charger.
The Hellcat was initially proposed back in 2011, back when Fiat was deciding its future strategy for Chrysler Group, according to Automotive News. At the time, the company was just emerging from its bankruptcy doldrums, and an ultra-high-performance V8 wasn't exactly a must-have item. The program didn't move forward. However, SRT engineers kept fighting, according to AN, and four months later, they received the green light to pull the project off the shelf and continue developing the Hellcat. The muscle car world is certainly better for that decision.
The work of those engineers focused on taking Chrysler's standard 6.2-liter V8 and making it reliably handle all of the extra power from the supercharger. "It came down to micron levels of changes in the crank to be able to withstand the pressures of the engine," said Chris Cowland, director of advanced and SRT powertrain, to Automotive News. The changes amounted to switching out about 91 percent of the parts to make the Hellcat, including some quite minuscule alterations. For example, the washer holding the supercharger pulley is embedded with industrial diamonds to keep it from slipping.
