2023 Chevrolet Silverado HD reportedly getting mammoth torque

Chevrolet just gave the light-duty Silverado a significant round of updates. It hasn't detailed the changes it has in store for the heavy-duty model yet, but a recent report claims the truck will arrive with significant engine upgrades. Without citing sources, website TFL Truck reported that the current pickup's 6.6-liter Duramax turbodiesel V8 will return in the updated model. Its displacement won't increase, but its output will reportedly grow to 505 horsepower and a mammoth 1,085 pound-feet of torque. To put those figures into perspective, the 6.6-liter makes 445 horsepower and 910 pound-feet of twist in the 2022 Silverado HD; GMC's Sierra HD is available with it as well. Bumping the Duramax's output is a way to keep up with the competition. Arch nemesis Ford offers buyers who have extremely heavy things to tow 475 horsepower and 1,050 pound-feet of torque from a 6.7-liter turbodiesel V8. Over at Ram, the most powerful engine available in a heavy-duty truck posts numbers of 420 and 1,075, respectively. If the report is accurate, Chevrolet will enviably take the horsepower and the torque crowns in the segment. What remains to be seen is what effect the increases will have on the Silverado's towing capacity. As of writing, it's capable of towing up to 36,000 pounds (approximately 15 times the weight of a 2021 Mazda MX-5 Miata). Moving out of the engine bay, the 2023 Silverado HD will receive an updated exterior design that will again help differentiate it from the smaller, light-duty model. We're expecting the next round of updates will also bring new tech features, and it's reasonable to assume that the trim structure will evolve; Chevrolet might notably shift the HD in a more outdoorsy direction to satisfy a growing demand for off-road-focused trucks in the United States. None of this is official; Chevrolet is keeping its lips sealed about the updated Silverado HD. Full details will likely emerge in the coming months, and sales are tentatively scheduled to start in time for the 2023 model year.

Fullsize GM SUVs have a problem that's making owners sick

Some fullsize SUV owners are getting sick, thanks to a buffeting and vibration problem in 2015 model year examples of the Chevy Tahoe and Suburban, Cadillac Escalade, and GMC Yukon. According to owners' complaints to the National Highway Traffic Safety Administration, the issue can vary from an annoying vibration inside the cabin to an experience so severe that it leads to dizziness and headaches. General Motors is aware of the complaints, but the fix isn't so simple. According to spokesperson Tom Wilkinson to Autoblog, the company "has been tracking this issue for a while." The problem has a fairly low incidence rate, but when it does occur the issue can be "uncomfortable and annoying for owners." There's no precise cause for the issue, Wilkinson claims, and in some cases, simply balancing the tires or changing the door seals can make it go away. However, not all of the fixes are so simple. AutoGuide dug deep into the problem and discovered a GM preliminary information bulletin that advised dealers to remove the headliner and to check the roof's bonds to the bows that go across the vehicle. However, that document included a note that the solution might not entirely eliminate things. According to AutoGuide, adding Dynamat insulation to the roof sometimes helped the problem. A GM spokesperson also told AutoGuide the company fixed the problem at the end of the 2015 model year, and didn't go into any more detail. This roof issue seems linked to some of the worst droning in these SUVs. According to one complaint from a 2015 Suburban owner to NHTSA: "Roof will not remain attached to the roof bows. This causes the buffeting similar to a window being down when all are up. The results span from annoying to painful." A 2015 Yukon owner claims to have another alleged cause for the problem in a NHTSA complaint from February 2015. This person brought their SUV to the dealer seven times over the course of four weeks for vibrations. The dealer replaced the driveshaft, suspension components, and more, but nothing worked. According to an engineer to the service adviser: "In an effort to prevent roll overs, they designed the frame and body mounts too stiff. There are 40 engineers working on issues, they have no solutions that work across the board." Wilkinson told Autoblog that GM is working with customers on an individual basis to rectify things. Since these are newer vehicles, dealers should also fix the problem under warranty.

Which of these high-powered pickup classics would you choose?

High-performance pickups would appear to be having a moment on the auction site Bring a Trailer, with two tempting examples up for auction right now: a 1971 Ford Ranchero GT and a 1991 GMC Syclone. These trucks are a generation apart, but they each represent the peak muscle truck of their time. The Ranchero, of course, was Ford's car-based pickup, and Ford took advantage of its Torino roots by offering the same ultra-high-performance 429 Cobra Jet V8 in the Ranchero as it did in the Torino-branded coupes and convertibles. The 429 V8 in this truck is said to be numbers-matching, and it looks the business topped with an air scoop poking through the hood. It's paired with a three-speed automatic and a limited slip differential, reportedly one of only 82 1971-model Rancheros with this powertrain combo. As a Ranchero GT, this example sports hidden headlights, and the dual sport mirrors and vinyl top further establish its kinship with its passenger-car siblings. A set of factory Magnum 500 wheels and a respray in the original red add to the muscle-truck vibe. Two decades later, car-based pickups were dead, so when GMC decided to revive the muscle-truck genre it did so with the mid-size Sonoma. The resulting Syclone put a more modern spin on the fast-pickup idea (and on the spelling of "cyclone"). This hi-po hauler uses a 4.3-liter V6 topped with a Mitsubishi turbocharger that helped it make 280 horsepower. It's mated to a floor-shifted four-speed automatic and a Borg-Warner all-wheel-drive system with a 35/65 torque split. The Syclone was a one-year-only model, of which just under 3,000 were built. All were black with matching cloth seats with red accents. The only other '71 Ranchero to appear on BaT was a non-original GT with a 351ci V8 that was a no-sale at $7,900. This Ranchero is already nearly double that figure. Of the four previously Syclones that have crossed BaT's virtual auction block, two have sold, for $36,000 and $50,000, but both had lower miles than this truck. At this writing, these two trucks are neck-and-neck, both in the mid teens with both auctions set to end April 23. Which powerhouse pickup makes you want to put your money down?
