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.

Black Friday could power record November sales

Black Friday allows some shoppers to line up in the wee hours for doorbuster deals on laptops and TVs, but the day after Thanksgiving could mean huge profits for automakers this year, too. Multiple industry analysts predict record growth for the industry for November, and the upcoming incentives could help those numbers. TrueCar predicts that Black Friday incentives could provide a major boost, and it estimates a November sales jump of 3.9 percent from last year to a record for the month at over 1.35 million vehicles. As examples of potential deals, Chevrolet, Buick, and GMC plan to offer up to 20 percent off some models, and FCA US has no-interest financing for up to 75 months from its brands. "Consumers are excited about Black Friday promotions and these month-long events appear to be resonating with car buyers." Eric Lyman, TrueCar's vice president of industry insights, said in the report. Black Friday only recently became a big day for auto sales, according to an analysis from Edmunds. Last year, Thanksgiving weekend posted double the sales as any other weekend in the month. The company predicts a sales volume of over 1.33 million vehicles for November. If that happens, it would be the beat the previous record of 1.32 million sales for the same month in 2001. Some forecasts temper the gains for November but only slightly. Kelley Blue Book predicts flat year-over-year sales at 1.3 million vehicles, but that's largely because there are two fewer sales days in 2015 versus in 2014. "Black Friday deals on vehicles have grown in popularity in recent years, and should be a big contributor to this month's sales results," said analyst Tim Fleming in the study. The combined research from J.D. Power and LMC Automotive have the lowest November prediction among this group at just over 1.279 million sales for the month versus 1.299 million in 2014. However, once the researchers adjust the figures for the two fewer selling days, 2015 could actually be seven percent higher than last year. TrueCar Finds New Auto Sales in November to Reach Monthly Record Black Friday promotions bolster sales gains; industrywide incentives up 6% from last year November 24, 2015 12:11 PM Eastern Standard Time SANTA MONICA, Calif.--(BUSINESS WIRE)--TrueCar, Inc. (NASDAQ: TRUE) projects total new vehicle sales, including fleet deliveries, will reach 1,352,500 units in November, a 3.9 percent increase from a year ago and the highest ever for the month.

2023 GMC Canyon with ZR2-style off-road suspension caught in spy photos

GMC appears to be testing its redesigned 2023 Canyon pickup with an updated suspension lifted from the ZR2 variant of its Colorado twin. This heavily camouflaged prototype packs what look like Multimatic's DSSV dampers disguised with a black vinyl wrap.  Rumors have pointed to a GMC variant of the Colorado ZR2 since the midsize pickup adopted the AT4 branding for its off-road variant. GM appears to be ready to adopt the formula for GMC's more-upscale pickup as it has for the Silverado. The latter, which has now been officially confirmed, has been spied on the road with its own DSSV shocks disguised in the same fashion as those seen here. This prototype is riding high – even for an AT4 – and sports a set of knobby Goodyear Wrangler all-terrain tires. We can tell that this is a Canyon rather than another Colorado thanks to the GMC-style fog lamp design, which differs from the Colorado prototypes we've already seen testing. Like the Colorado, the redesigned Canyon is expected to be offered with just one engine: a 2.7-liter turbocharged four-cylinder lifted from the Silverado and Sierra pickups.  Look for the Canyon to debut alongside its Chevy twin sometime in the next year or two as either a 2023 or 2024 model.  Related video: This content is hosted by a third party.
