GM to idle car production at five factories as Americans continue CUV love affair

In case you needed another reminder that Americans have fallen out of love with sedans, General Motors today announced plans to idle five factories in January in a bid to cut its inventory to 70 days. Detroit-Hamtramck Assembly ( Buick LaCrosse, Cadillac CT6, Chevrolet Volt and Impala) and Fairfax Assembly in Kansas ( Chevy Malibu) will stop production for three weeks. Lansing Grand River ( Cadillac ATS and CTS, and Chevy Camaro) is going down for two weeks, while Lordstown, OH ( Chevy Cruze) and Bowling Green, KY ( Chevy Corvette) will go idle for a week each, Automotive News reports. GM's shutdown reflects a broader problem with the company's supply – at 847,000 vehicles, the company's supply increased unsteadily from a low of 629,000 units in January of 2016. That's more than a 25 percent increase in the past year. Citing information from Autodata, The Detroit News reports that at the end of November, GM had a 168-day supply of LaCrosses, 177 days' worth of Camaro, 170 days of Corvette, 121 days for Cruze, 119 days for ATS, 132 days for CTS, and 110 days of CT6. Meanwhile, inventory of the company's more popular vehicles is actually below the professionally accepted 60- to 70-day supply, The News reports. The Trax, Colorado pickup, and GM's full-size SUVs are sitting below 50 days and experiencing year-over-year sales increases. GM needs a rethink of its inventory levels, which is something that's apparently coming. "We're going to be responsible in managing our inventory levels," GM spokesman Jim Cain told The News. Another unnamed spokesman told Automotive News the company's day-to-day supplies would "fluctuate before moderating at year-end." But at least one analyst thinks this won't be the last time Detroit needs to stop production to level things out. "Incentives are elevated, residuals are declining, and rates are rising," Brian Johnson, an analyst with Barclays, told The News. "And while GM in particular may benefit in the months ahead from new product launches, it's important to recognize that GM's inventory is elevated at the moment, and it wouldn't surprise us if they need to announce another production cut – which could pressure the stock."

Torque time | 2017 GMC Sierra HD First Drive

It's not the truck that counts, it's how you use it. It's the heavy stuff you fit in its bed or the extremely heavy stuff that gets hooked up to the tow hitch. The ATV, the Jet Skis, the trailer with more square footage than a Greenwich Village apartment. Perhaps you need to get Seabiscuit or, uh, Mr. Ed to wherever they need to gallop next. In our case, there's a pair of very serious-looking snowmobiles perched atop the bed of a GMC Sierra. They spread out as wide as the extended tow mirrors, and their back halves are dangling precariously beyond the truck. Sterling Archer would be giddy; I'm a little nervous. But only because canyon roads and wide vehicles with a high center of gravity go together like peas and custard. The added weight is no sweat at all. That's because this is the 2017 GMC Sierra HD Denali, a truck with the sort of enhanced power, torque, suspension, and stopping capability expected of a heavy-duty pickup. And for this year, the power and torque get a serious bump courtesy of a new 6.6-liter Duramax turbodiesel engine reengineered from almost the ground up with 90 percent new parts. It's quieter and more efficient and it emits less, while most importantly producing 445 horsepower and 910 pound-feet of torque. That's up from 397 and 765, respectively. Chevy fans will note that the same engine is also available in the updated 2017 Silverado HD. Now, for those keeping score at home, that horsepower is best-in-class but the torque number still falls short of the new Ford Super Duty and its Power Stroke diesel V8's 925 lb-ft. Aw shucks. For the record, GM's engineers didn't seem too concerned that they weren't able to eke out an extra 16 torques just to say they're No. 1. "We wanted to first meet emissions and then deliver the maximum horsepower and torque we could, and deliver it over the widest usability range possible," said chief engineer Eric Stanczak. And let's be honest here, 910 pound-feet is herculean, and once again, a jump of 145 lb-ft. Or one Subaru Impreza's worth. Or 110 more than the best Ram can do on a 2500, and its Cummins turbodiesel's 800 pound-feet was eye-popping not too long ago. (The Ram 3500 maxes out at 900 lb-ft with the right transmission.) Ah, but here's the rub. That Cummins-equipped Ram 2500 can still tow more weight according to SAE-compliant measurements – 17,510 pounds for a Ram crew cab with a short bed versus 13,000 in the similar Sierra 2500. The Ford F-250 can manage 15,000.

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.
