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.

2014 Chevrolet Silverado tows in new configurator, microsite

Judging by your continued enthusiastic response to configurator notices, dear reader, you enjoy speccing out new cars as much as we do. Better still, there tends to be even more ways to personalize, configure and bloat theoretical MSRPs on full-size trucks as there are with more ordinary passenger cars. In addition to trim level, engine and transmission choices, truck buyers usually have to specify items like cab configuration, bed length, number of driven axles, tow packages, gear ratios and all sorts of bits and bobs.
That's why we're pleased to see the DIY specification utility for the 2014 Chevrolet Silverado come alive so soon after this week's Detroit Auto Show debut. While the configurator lacks pricing (General Motors hasn't announced numbers yet) and full options, you can still spec out your half-ton rig, and even print it out or email it to your friends. Beyond the configurator, the new model-specific site is pretty cool, too, with various videos and closer looks at the truck's new features.
The new Chevrolet pickup range won't be on dealer lots until sometime this summer, so whether you're a building contractor, an avid sportsman or just a guy or gal that loves full-size trucks, you might want to check out the link below to keep your appetite whetted. If you're more of a Sierra fan, well, it looks like you're going to have to wait a while - GMC hasn't updated its site yet.

GM may kill 6 car models as it works with UAW to tackle sales slump

The president of the United Auto Workers union said on Thursday the union is talking with General Motors about the potential threat to plants and jobs from slumping U.S. car sales. GM's response will be more trucks and SUVs, and sources say at least six slow-selling car models may be killed off. "We are talking to (GM) right now about the products that they currently have" at underused car plants such as Hamtramck in Michigan and Lordstown in Ohio, and whether they might be replaced with newer, more popular vehicles such as crossovers, Dennis Williams told reporters. "We are tracking it (and) we are addressing it," Williams added. GM has cut shifts at several U.S. plants this year as inventories of unsold cars have ballooned. Industry analysts said more jobs could be at risk as the automaker wrestles with permanently shrinking production of small and midsized sedans. GM is reviewing whether to cancel at least six passenger cars in the U.S. market after 2020, including the Chevrolet Volt hybrid, which could be replaced in 2022 with a new gasoline-electric crossover model, Reuters has learned from people familiar with the plans. Other GM cars at risk include the Buick LaCrosse, Cadillac CT6, Cadillac XTS, Chevrolet Impala and Chevrolet Sonic, sources said. Some analysts have singled out GM's Hamtramck plant in Detroit as one of the most vulnerable because of plummeting car sales. The plant, which opened in 1985, builds four slow-selling models: Buick LaCrosse, Chevrolet Impala, Cadillac CT6 and Chevrolet Volt. In the first half, it built fewer than 35,000 cars, down 32 percent from the same period in 2016, according to suppliers familiar with GM's U.S. production schedule. The typical GM assembly plant builds 200,000-300,000 vehicles a year.COMING ATTRACTIONS: TRUCKS AND SUVS GM must "create some innovative new products" to replace slow-selling sedans "or start closing plants," said Sam Fiorani, vice president of AutoForecast Solutions. The auto maker already has begun to shift future production plans from cars to trucks, according to Morgan Stanley auto analyst John Murphy. He estimates that fewer than 10 percent of the new vehicle models that GM will introduce over the next four years will be passenger cars, with the rest divided among trucks, SUVs and crossovers. GM plans to add production of the new Cadillac XT4 crossover next year to its Malibu sedan plant in Fairfax, Kansas.
