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.

Chevy, GMC and Ram dealers are worried they'll run out of new pickups

One of the unexpected side effects of the ongoing coronavirus pandemic is a shortage of pickups at Chevrolet, GMC and Ram dealers. Supplies are running out, and the factories that build these trucks remain closed. Stores across the nation began increasing incentives in March, when the first stay-at-home orders were issued, in a bid to continue luring buyers into showrooms. They also launched online sales channels, or expanded their existing digital business. Sales nonetheless plummeted in April 2020, but in-demand vehicles, like the Ram 1500 and the Chevrolet Silverado, are still selling relatively well thanks in part to the aforementioned incentives. Pickups outsold sedans for the first time in April 2020, according to The Detroit News, by 17,000 units. The problem is that General Motors, Fiat Chrysler Automobiles (FCA), and Ford temporarily closed their factories in March. "The pipeline is very dry," said Mike Maroone, the CEO of a large dealership group named Maroone USA, in an interview with Automotive News. He told the publication his Chevrolet stores are sitting on a 30-day supply of the Silverado, which is one of America's best-selling vehicles. "That is a problem for us," he concluded. Coronavirus-related lockdowns and factory closures compound problems already faced by dealerships who represent General Motors-owned brands. They entered 2020 with a thinner inventory than a year earlier due to the 40-day United Auto Workers (UAW) strike that paralyzed the company late in 2019, and the 0%, 84-month offers announced in March have sapped supply. Ram wasn't affected by a strike, but it has relied heavily on generous incentives to move trucks off lots. Ford, on the other hand, limited incentives to 2019 models. Inventory levels differ greatly from region to region. The national average for the Silverado stood at an 82-day supply in March 2020, down from 120 in March 2019. Ram stores had a 114-day supply of the 1500 (compared to 134 a year earlier), while Ford bucked that trend with a 111-day supply versus 84 in 2019. Don't panic if you're in the market for a truck; we're not facing a complete drought. Automotive News added that America's light-duty pickup inventory could fall to 400,000 units by the end of May, and drop further to 260,000 units in June. For context, there were about 700,000 light-duty trucks in stock in May and June of 2019. That's unquestionably a sharp drop, but there will still be over a quarter of a million trucks to choose from.
