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."

2021 GMC Canyon AT4 Road Test | The everyday tool

Bold take: The GMC Canyon is the most well-rounded midsize truck. Admittedly, “well-rounded” is a lukewarm compliment, but the Canyon does nearly everything well. It is not the flashiest, which is undeniably the Jeep Gladiator. Or the most comfortable, which is the Honda Ridgeline. But for those seeking a midsize truck that looks like a truck, drives like a truck and has a solid interior, the Canyon is the right formula. We would test the 2021 GMC Canyon AT4 for a week and find that itÂ’s pleasant, capable and sturdy off-road. We would haul a bookshelf in the bed, get dirty during a woodsy soft-road jaunt and pile up the miles running around town. In short, itÂ’s exactly what most need in a midsize truck.  The AT4 model is new for 2021, and it replaces the All-Terrain model, a move GMC is rolling out across its lineup. The AT4 adds an off-road-tuned suspension with hill-descent control, beefy 31-inch Goodyear Wrangler DuraTrac tires wrapped around 17-inch aluminum wheels, standard four-wheel drive with locking rear differential and a transfer case skid plate. The AT4 punches up the CanyonÂ’s appearance with red tow hooks, dark chrome elements and a bigger grille thatÂ’s similar to the SierraÂ’s. The Canyon Denali, which was also refreshed for ‘21, is showier, but the AT4 trim feels cooler with its understated off-road vibes. Considering this, we head out for an afternoon drive along a familiar route through DetroitÂ’s northern suburbs. The Canyon is a solid daily driver. The 3.6-liter V6 rated at 308 horsepower and 275 pound-feet of torque is widely used in General Motors vehicles. ItÂ’s powerful and actually sounds pretty good — even throaty — in GMCÂ’s midsize truck. Our passengers are surprised to be pulled back in their seats during hard acceleration, and the eight-speed automatic transmission is well-calibrated for the many jobs the Canyon is called upon to perform. This powertrain, standard in the AT4 and Denali trims, is a step up from the 2.5-liter inline-four and six-speed auto offered on the lower models. ItÂ’s worth it. The 2.8-liter Duramax diesel is an option on higher-spec Canyons, and its 369 lb-ft of torque is tantalizing. For everyday use, take the V6. Our tester with the gasoline V6 and four-wheel drive can tow as much as 7,000 pounds, has a maximum payload of 1,609 pounds and has respectable fuel economy of 17 mpg in the city and 24 mpg on the highway.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).
