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.

GMC moved the headlights down on the 2024 Sierra EV to prevent glare

There are a lot of things that are different between the 2024 GMC Sierra EV’s design and the gasoline Sierra pickup, but one we noticed right away was the headlight placement. On GMÂ’s full-size gasoline trucks, the headlights are about as far up the front fascia as they can be. In the Sierra EV, theyÂ’re positioned significantly further down and into the lower bumper below the grille. Why are we highlighting this particular aspect of the design? Well, unless you only ever drive massive, high-riding trucks, youÂ’re probably very accustomed to being frequently blinded by them on the road these days. In describing the Sierra EVÂ’s headlight placement, designers told us they intentionally put the lights further down to improve matters. We pulled Phil Kucera, a GMC design manager, aside to ask him about the change. “It tends to be a better spot where itÂ’s not glaring in other peopleÂ’s eyes, right, the lower you get,” Kucera says. Beyond blinding others, putting the headlights lower on the face of the truck improves headlight performance for the driver, too. “Typically the lower the better, because thatÂ’s where theyÂ’re going to be on the road, so thereÂ’s less to reflect off of in fog or rain,” Kucera explained. “If you get them up at a certain height, theyÂ’re going to be reflecting certain things like snow, rain or things like that in your eyes.” 2024 GMC Sierra EV Denali Edition 1 View 13 Photos Of course, youÂ’ll notice on the Sierra EV that the daytime running lights (DRLs) are still big and bold in the upper part of the front end. These lights are around for decor, though, and act as pieces of design rather than a functional way to see at night. In other words, theyÂ’re lights, but theyÂ’re not going to dazzle oncoming traffic or cause glare for the driver like a headlight pointed down the road will.  Moving those lights further down in the front should hopefully be a net positive for other drivers coming across the Sierra EV and for drivers of the truck themselves. How the lights are aimed plays just as much a role in how other drivers perceive oncoming lights, though, so weÂ’ll have to wait and see the real-world performance on this one.  WeÂ’ll also note that moving the actual headlights further down the front end doesnÂ’t take anything away from the design of the Sierra EV. It still features a strong, upright stance that the world is accustomed to seeing from new trucks these days. ItÂ’s no surprise, but GM agrees.

2020 Harley-Davidson GMC Sierra brings the iconic brand to a new truck

The Harley-Davidson Ford F-150 rides alone no longer. Thanks to the Tuscany Motor Company, it now has a fellow truck associate to cruise with side-by-side on the open roads. Introducing the 2020 Harley-Davidson GMC Sierra, which will make its official debut at the 2020 Barrett-Jackson Scottsdale auction. For years, a Harley-Davidson special edition package has been associated with the Ford F-150 nameplate. Although Ford does not offer a direct option from the factory, Tuscany Motor Company answered the demand and now builds truck packages that carry the famous American motorcycle name. With the direction of Harley-Davidson, Tuscany creates interior and exterior customizations that reflect notable and iconic features of the bikes. This year is the first time Tuscany has ever offered a Harley-Davidson package on a GMC Sierra, and as expected, it's pretty similar to the one offered on the F-150. The package includes at least 60 exclusive parts, and the Sierra is available in Onxy Black, Summit White, or Satin Steel Metallic.  Setting the tone are Fatboy-inspired 22-inch milled aluminum wheels wrapped in chunky 35-inch all-terrain tires. As Tuscany is a division of Fox performance parts, the truck rides on a specially designed BDS suspension with tuned Fox shocks and lateral stability bars. The truck also has a redesigned front bumper and grille with an integrated LED light bar for off-roading, power running boards with rock guard trim and entry lights, color-matched Harley-Davidson-designed fender flares, custom front fender vents with the Harley logo, an induction-style hood, a redesigned rear bumper, and a tuned exhaust with billet tips. More badging, tailgate cladding, a windshield header, orange tow hooks, and a bed rug add extra pizzazz. Finally, for all the planes, drones, and aliens who are eyeing pickups from the sky, the tonneau cover is debossed with the Harley-Davidson logo.  Inside, the fan pack includes leather seating with orange diamond stitching, and piano black door panels, console, and trim. Harley-Davidson badging and branding is on the seats, on the center console, on the floor mats, the door sill inserts, the instrument gauges, and even the pedals.  If this is up your alley, and you're interested in buying, the Sierras, no matter the color, start at $94,995 before taxes and fees.
