Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"

GMC Sierra AT4X reportedly on the way, nameplate could be GMC's ZR2

In 2016, GM filed an application with Mexico's Institute of Industrial Property to reserve the name AT4X, and in 2019, the automaker made the same request to the U.S. Patent and Trademark Office. Seeing that GMC's current AT4 trim replaces the former All Terrain trim used on the last-gen Sierra pickup, there have been suspicions ever since those trademark filings that GM would use the AT4X name to replace GMC's former All Terrain X trim. GM Authority reports that this is precisely what's going to happen, citing "sources familiar with the matter." The outlet even gleaned an equipment group number: 4SG for AT4X, whereas AT4 is equipment group 4SB.  The surmise is that GMC is again developing its versions of Chevrolet's dirt-clobbering pickups that wear the ZR2 name. Spy shooters caught the GMC Canyon earlier this month trotting around on Multimatic's DSSV dampers and a set of 33-inch tires like its Colorado ZR2 sibling. The Canyon already offers an AT4 trim, it's thought this beefier setup will roll into the lineup as an AT4X.  Stepping up to the half-ton league, at the end of last month Chevy released a teaser for the Silverado ZR2, which had been caught in prototype guise (pictured at top) around Detroit on at least two occasions. We've mused that the production Silverado ZR2 could take some hardcore off-roader cues from the factory-upgraded Silverado ZR2 race truck like a lifted stance, long-travel front suspension, four-leaf springs instead of three-leaf, electronic locking front and rear differentials, and a wider track. One of the production prototypes was caught on 33-inch tires, but we wouldn't be shocked to see 35-inchers on the spec sheet. That size would match the race truck and the rubber fitted to the cross-town rivals Ford Raptor and Ram 1500 TRX. A GMC Sierra AT4X would be the plusher, pricier, chrome-ier version of the ZR2. The aforementioned Multimatic shocks could also be on the docket. We'd expect the GMC Sierra AT4X to bow with the heavily updated 2022 pickup, whenever that arrives. Events around the world of late delayed the pickup, its launch now thought to happen late next year or in early 2023. Related Video:  

GM now finishing and shipping pickups it had parked for lack of chips

DETROIT — General Motors is more than halfway through shipping newly-assembled pickups that it had parked due to a shortage of semiconductor chips, a top executive at the No. 1 U.S. automaker said on Friday. "We've made great progress," Steve Carlisle, GM's North American chief executive said at the Reuters Events Automotive Summit. "We're a bit better than halfway through that at the moment and our goal would be to clear out our '21 model years by the end of the year. We'll have a bit of a tail of '22 model years into the new year but not for too long." The global chip shortage has forced automakers like GM to idle production or in some cases mostly build vehicles and then park them until the necessary chips can be installed, allowing those vehicles to be then shipped to dealers. Last month, GM Chief Financial Officer Paul Jacobson cautioned that GM's third-quarter wholesale deliveries could be down by 200,000 vehicles because of chip shortages. He did not break out what share of that was trucks. To expedite transportation of newly-built vehicles to dealers, Carlisle said GM bought a number of car haulers to deliver them from factories or distribution centers. The Detroit automaker has also allowed dealers to pick the vehicles up themselves in some locations. Carlisle said new vehicle inventories have shrunk to below 20 days in the United States due to the supply chain disruptions, but the company wants to get that back up to 30 to 45 days with some getting to 60 days depending on the product line. GM sees sales of gasoline-powered vehicles being steady over the decade and real growth opportunity in electric vehicles and software, with one not undermining the other, he said.
