GM to invest $150 million in Flint to boost heavy-duty pickup production

FLINT, Mich. — General Motors President Mark Reuss said on Wednesday that the automaker is investing about $150 million at its Flint Assembly plant in Michigan to boost production of heavy duty trucks by another 40,000 vehicles a year. Reuss announced the investment at the Flint truck assembly plant wearing a United Auto Workers pin. The Detroit automaker had announced back in February it was adding 1,000 jobs in Flint to build a new generation of heavy-duty pickup trucks. GM did not say that the latest investment would add more jobs at the plant, but Reuss said there could be opportunities to add workers as the launch of the automaker's new trucks progresses. GM has been under pressure from President Donald Trump and lawmakers of both parties to add jobs in the United States after it said last November it would idle the Chevy Cruze assembly plant in Lordstown, Ohio, and likewise had no new products for three other U.S. manufacturing plants. The Flint investment will include upgrades to the plant's conveyors and other new tooling, and will be completed in the first half of 2020. GM has invested more than $1.6 billion in the plant since 2013. Last month, GM said it would invest $24 million to increase truck production at its assembly plant in Fort Wayne, Indiana, which makes Chevrolet Silverado and GMC Sierra models. Sales of heavy-duty pickups in the United States have grown to more than 600,000 vehicles a year, up more than 20 percent since 2013, according to industry data. Prices for luxury models can easily top $70,000. GM's Chevrolet and GMC brands have long trailed Ford's F-series heavy duty trucks in the lucrative segment. The new Chevrolet and GMC heavy duty trucks have been re-engineered to tow heavier trailers, and keep pace in what has become an arms race among the Detroit Three automakers to claim superior torque and towing capability.

GMC Canyon AT4X rumored to get more extreme AEV Edition

When GMC debuted the new 2023 Canyon pickup in August, the midsize lineup gained the hardcore AT4X off-road trim the brand has been spreading throughout its wares. The new top-of-the-line model is GMC's version of the Chevrolet Colorado ZR2 and features the same off-road goodies, like the Multimatic DSSV suspension, unique front fascia, more skid plates, front and rear locking differentials, and a Baja drive mode turning the 33-inch tires. The Edition 1 launch model adds to the production goods by bolting on a front safari bar with a 30-inch light bar, a Comeup winch, an upgraded front skid plate, reconfigurable bed rails, front and rear underbody cameras, and special badging. The Canyon AT4X Edition 1 was gone almost immediately, because of course. However, Muscle Cars & Trucks reports that something just as special could be coming for buyers in the form of a Canyon AT4X AEV Edition. American Expeditionary Vehicles already breathed all over the last-gen Chevrolet Colorado and the current Chevy Silverado, looks like GM not only intends to keep the relationship going but expand it. MCT credits a source for news that the AEV-worked Canyon will get a snorkel and 35-inch tires. Chevrolet offered a snorkel as an aftermarket piece for the Colorado ZR2 Bison, and AEV sold a ZR2 Bison version with a snorkel attached. The new report claims GMC will make the elephant trunk a factory option, fitted to the driver's side this time instead of the passenger's side because of the new engine. The 35-inch tires would be a huge add-on, giving the Canyon the same kind of footprint as the Jeep Wrangler Rubicon Xtreme Recon and a couple of Ford Bronco trims. The additional two inches over the 33-inch tires on the AT4X make a big difference when the trail gets dicey. MCT says the AEV will get the same bumper as the Edition 1, which means a reduced approach angle in return for an integrated winch. The standard AT4X bumper permits a 36.9-degree approach angle, the winch-equipped Edition 1 drops that to 32.8 degrees. It's not clear which winch would hide behind that bumper, though. GMC factory fit is the Comeup Seal Slim 9.5rs rated at 9,500 pounds. AEV offers a Warn 9.5 XP-S with the same weight rating for its Colorado ZR2 Bison.  Speaking of which, since the Colorado arguably started all this, Chevy fans can expect their midsizer to acquire the same bundle as the Canyon AT4X AEV.

'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).
