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

Is your new-car warranty good at the race track?

We've all heard the horror stories. Your buddy knows a girl that was dating a guy whose best friend's brother once broke his brand-new, recently purchased performance car while making runs at a drag strip or laps at a track day, and the manufacturer wouldn't cover the repair under warranty. True story? Urban legend? Complete crap? Yes, no, maybe. One thing's for sure: Automotive warranties have always come with caveats. In 1908, an ad in the Trenton Evening Times clearly stated: "All Ford Cars Guaranteed for One Year." Although it changed over time, by 1925 the Ford New Car Guarantee only covered 90 days on material and 30 days on labor, and it clearly stated that that there was "No guarantee whatever on Fan Belts, Glass, Bulbs, Wiring, Transmission, Bands, Hose Connections, Commutator Shells, Rollers, Spark Plugs or Gaskets." Whether or not Ol' Henry would pay to fix your Model T if you broke it shaving a tenth off your lap time at the local board track seems to be lost to history. We're guessing no. But what about today? Do new-car warranties in 2017 cover cars when they are driven on race tracks? We researched the warranties of 14 auto brands to find out, and the answer is yes, no, maybe, depending on the brand, in some cases the model, and whether or not your car is modified from stock. Acura has been out of the high-performance car game for a number of years, but jumps back into the party in 2017 with its hybrid-powered $173,000 NSX supercar. And Acura's warranty, as well as Honda's, clearly states that it does not cover "the use of the vehicle in competition or racing events." View 33 Photos So we asked Sage Marie, Senior Manager of Public Relations for Honda and Acura. "If the car is stock, the warranty covers it on a track just as it does on the street. No question," he told us. "However, if the car is modified, say with slick tires or other components that would put higher stresses on the vehicle's parts and systems, then we would have to investigate the circumstances further." Marie went on to say the same would be true for any Acura model or Honda vehicle, including the new 2017 Honda Civic Si. This became a common theme. Chevrolet actually started this practice with the fifth-generation Camaro on the high-performance ZL1 and Z/28 models.

Would you pay $17 a month to give your older Ford connectivity?

When it was first introduced in 2007, there was nothing like the original Ford Sync system, since it allowed car owners to connect and use a portable device better than anything that came before it. And because it was a brought-in/tethered and software-based system, Sync leveraged a device's connectivity and was easily updated. It took competitors awhile to catch up: Toyota Entune wasn't available until 2011, and Chevy MyLink didn't roll out until 2012. But now Ford is the one playing catchup since it stuck with the brought-in strategy while most other automakers were quicker to add connectivity via an embedded cellular modem. Ford initially installed 2G/3G modems in its small fleet of electric and plug-in electric vehicles starting in 2012 so that owners could keep tabs on charging. Embedded connectivity came to Lincoln in 2014, and Ford began adding onboard 4G LTE via Sync Connect to select cars starting with the Escape in 2015. To get more cars connected more quickly, last week the automaker rolled out its FordPass SmartLink solution that plugs into the OBD port of 2010 to 2017 model year vehicles. This lets owners retroactively get onboard Wi-Fi, set up a "geo-fence" to keep tabs on a car's location, receive vehicle health reports and allows remote engine starting and door locking/unlocking using a smartphone app, among other features. But to connect older Ford vehicles will cost owners $16.99 a month for two years, not including installation. Ford throws in 1 GB of data or a 30-day trial, whichever comes first, after which owners have to add the vehicle to their Verizon shared data plan, which supplies connectivity for SmartLink, or establish a new account. (Disclosure: Autoblog is owned by Verizon.) By comparison, GM's 4G LTE data plans start at $10 a month for 200 MB and goes up to $30 for 3 GB, and owners can also add a car to an AT&T shared-data plan. But OnStar doesn't have a separate monthly subscription for the embedded modem or an installation charge, and standard features via the RemoteLink Mobile App are free for the first five years of ownership. FCA's Uconnect Access service also uses an embedded modem to provide similar telematics features for $20 per month following a free one-year trial, while a la carte in-car Wi-Fi is offered for $10 per day, $20 per week or $35 per month.
