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.

Regular-cab, short-bed Chevy Silverado Trail Boss pickup looks great

For all the wild popularity of full-size pickups, there's one configuration that U.S. buyers are no longer offered: the regular-cab, short-bed truck. Interestingly, however, GM still does make this configuration, and both the Chevrolet Silverado and the GMC Sierra are offered with it — in the Mexican market. That body style, however, is available solely in ultra-basic work-truck form. But a custom wheel shop, JC Wheels in the Mexican city of Culiacan, has converted one of these Silverados to Trail Boss trim, and we're digging the result. The sporty shorty Silverado Trail Boss comes to our attention via GM Authority, after the shop posted it on their Instagram feed. The shop added a 3-inch lift, assist steps, Chevy alloy wheels, a Trail Boss front fascia including red tow hooks, and Trail Boss badging. They also added dark window tint, which seems like a good idea in sunny Mexico. In the U.S., the Silverado Trail Boss isn't offered at all in regular-cab form; it only can be had as a double cab or a crew cab, the latter with a choice of a short bed or standard bed. But size is often a hindrance for trucks that actually get driven on trails, where this regular-cab, short-bed variant's smaller wheelbase would be an advantage. Beyond that, the Trail Boss upgrades keep this configuration from looking like a basic-spec machine. That's even more true of the same outfit's previous efforts: the conversion of the GMC Sierra regular-cab, short-bed pickup into a Denali. With so many buyers choosing pickups as personal-use vehicles, it's not hard to think that this configuration could find an audience here. But the key would be to do as this Mexican firm has done and offer it in the desirable off-road and luxury trims, rather than as a basic work truck. Would you buy one? Sound off in the comments below. The next step would be to use this configuration as the basis of a full-size, two-door SUV, in the mold of the classic Chevy K5 Blazer and GMC Jimmy.
