GM exploring ways to raise half-ton Duramax diesel tow rating

Lots of truck owners cheered when GM announced fuel economy numbers for the 2020 Chevrolet Silverado with the 3.0-liter Duramax diesel inline-six. Even after Ram let loose its EPA mileage ratings for the 2020 Ram 1500 EcoDiesel, the Chevy oil-burner still took the trophy. The victory was years in the making, GM engineers spending an entire four-year development cycle refining the LM2 Duramax to increase mileage. The tradeoff, as well all know by now, is towing; the Duramax in half-ton duty pulls a maximum 9,300 pounds in the Silverado. Rivals across town can do more, the Ford F-150 PowerStroke rated at 11,500, the Ram 1500 EcoDiesel game to pull 12,560. GM engineer John Barta told Muscle Cars & Trucks that more hauling chops could be on the way, explaining, "We’re actually looking at upgrading some of the materials around (the engine bay) to see if we can maybe raise our tow rating." Engine bay materials are at issue due to thermal complexities underhood. John Barta, GM's assistant chief engineer of diesel engine controls, said the Duramax's inline-six configuration allowed engineers to get emissions hardware like the combined selective catalytic reduction, diesel oxidation catalysts, and diesel particulate filter unit closer to the engine, where it heats up quicker, getting emissions down quicker. But that filter puts another heat source in those confines, enforcing a cap on the tow rating to keep the engine and other systems from overheating. "If you look under the hood," he said, "youÂ’ll see a significant amount of silver ‘moon tapeÂ’ around to make sure things arenÂ’t getting overheatedÂ… if we were to go up in higher towing, which we can, we start impacting the possibility of deteriorating some of the components.” There isn't much space for more grille, so swapping for a better grade of "moon tape" or a different kind of material could reduce engine bay heat, extracting a higher tow rating in the process.  It's important to note a point Barta's been making for months about the Duramax figures, though. "Even though itÂ’s nice to brag about big numbers, in reality, light duty customers are not towing that large with their trucks," and, "We do know that (95 percent) of our light duty customers donÂ’t tow over 9,000 pounds." On our First Drive of the 2020 Silverado diesel we called out the tow rating, but emphasized that the Chevy and GMC have more important challenges to overcome.

Hot air balloons caught in high winds drag fullsize SUV

A sudden storm front whipped up enough wind to send some hot air balloons flying into the air in Wisconsin over the weekend. One ballon proved so energetic that it was able to drag a fullsize SUV across a field and into a stand of tents. The freak accident occurred at Balloonfest in Waterford, Wisconsin. Spectators were horrified as balloons dragged handlers to the ground and launched with terrified pilots clinging to their baskets. Organizers had started packing up the colorful balloons due to ominous storm clouds when the wind kicked up. "Happened just like that; it was crazy," Nathan Fricke, crew member, told Fox 6. Winds were clocked at 40 to 50 miles per hour. A balloon caught in the wind dragged a large SUV (we think a Suburban or Yukon XL) hundreds of feet and into a cluster of tents on the edge of the staging area where balloons were on display for festival goers. Considering that the SUV surely weighs well over 5,000 pounds, it's lucky that no one was injured in the incident. News Source: Fox6Now Weird Car News Chevrolet GM GMC SUV

GM releases full Super Bowl ad with GMC Hummer, Cadillac Lyriq: Take that, Norway!

GM just dropped its big Super Bowl ad, and it’s a good one. Will Ferrell, Kenan Thompson and Awkwafina all star in the 90-second ad titled “No Way, Norway.” The point of the ad is to get Americans hyped up about the upcoming electric vehicle range on its way from GM. Both the Cadillac Lyriq and GMC Hummer EV star throughout, but itÂ’s less about the vehicles, and more about changing attitudes about EVs in general. Ferrell comes after Norway aggressively, but in a playful and competitive way about how many electric cars sell in the Scandinavian country. Over half of all new car sales in Norway are of EVs, whereas GMÂ’s data show that just 4% of new cars sold in the U.S. are electric. Massive financial incentives from the Norwegian government can take much of the credit for why EVs sell at such high rates over there. However, GM thinks it can still rally the U.S. to get more excited about buying EVs once its fleet of cars using the companyÂ’s Ultium battery tech comes online. The ad is done with classic Ferrell comedy, and it sure did elicit some chuckles from us. It also follows the same “Everybody In” philosophy that GM announced back when it changed up the logo a short time ago. GM is inviting folks to strap in for the onslaught of EVs coming their way (for now, you can buy a Bolt). President BidenÂ’s administration has voiced support for a number of policies and actions to take for greater adoption of electric cars in the U.S. — we also know the federal government intends to transition its full fleet of vehicles to EVs. It's still unlikely that we make it to Norway's rate of electric car sales in the immediate future, but the U.S. could certainly begin to close the gap. Related video:
