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.

2019 Chicago Auto Show photo gallery: All of the grilles

Do you like trucks? How about grilles? Like really big, shiny, chromey, in-your-face, could-be-made-by-Broil-King grilles? Well, the Chicago Auto Show is the place to be. Traditionally known as the truck show of the annual auto show circuit (at least those covered by national media), Chicago has what seems like a small national park's worth of acreage devoted to both consumer and commercial trucks. From humble extended cab Ford Rangers to a mammoth F-650 with cherry picker sprouting from its aft quarters, there's bound to be a truck for everything. And they all have grilles. So above is our gallery devoted to them, because hell, why not? Should you want to know about the trucks attached to those grilles, check out our coverage below.

Chevy brings back Midnight Edition Colorado and Silverado for 2016

Chevrolet is capitalizing on the popularity of last year's shadowy Midnight Edition pickups with new versions at the Chicago Auto Show. The package's darker trim allows buyers to make their trucks look a little more menacing straight from the dealer. The 2016 Midnight Editions don't deviate from last year's monochromatic theme. The trucks feature blacked-out trim from the grille, badges, bumpers, and headlight bezels. The obsidian shades also appear on the side moldings and painted wheels. Chevy completes the dark theme with a black spray-in bedliner. Available with the Z71 package, customers can also get off-road equipment like an upgraded suspension, locking rear differential, and hill descent control – depending on the model. Chevy offered the Midnight Edition for the Silverado and Colorado last year, in addition to other models, and customers couldn't get enough of the dark trucks. "The Silverado 1500 Midnight was by far the most popular model in 2015, as demand outstripped supply in a matter of months. It only made sense to expand our special-edition offerings for 2016, including new Midnight editions," Sandor Piszar, Chevy's truck marketing director, said in the models' announcement. Chevy spokesperson Monte Doran told Autoblog the 2016 Midnight Edition pickups will be available this spring, but he wouldn't comment on pricing. You can get a good look at what to expect in the gallery above and expect live photos soon.

They join a growing portfolio of special-edition trucks whose popularity helped Chevrolet truck sales increase 27 percent last year – double the increase for the total truck market. "We introduced several special-edition trucks in 2015 – each combining equipment and appearance packages designed for specific enthusiasts in mind," said Sandor Piszar, Chevrolet truck marketing director. "They clearly resonated with buyers, as the special editions sold in one-third the time, and to younger, more affluent buyers than the industry average. "The Silverado 1500 Midnight was by far the most popular model in 2015," Piszar continued, "as demand outstripped supply in a matter of months.
