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.

GM follows Ford and Honda in skipping SEMA

The list of automakers skipping SEMA has become longer. First reported by Muscle Cars and Trucks, and confirmed to us by a company representative, General Motors will not have an official presence at the aftermarket show. It joins Ford and Honda in leaving the show. It will be a large hole in the show, with the GM brands typically filling a significant swath of available show space in one of the main halls. GM hasn't provided much explanation for the move, either. The GM representative provided Autoblog with the same statement that Muscle Cars and Trucks got: "GM has made the decision not to participate in the 2022 SEMA Show. The SEMA show has always inspired us, and accessories and performance parts remain an important part of our business." We also asked if we would see any sort of announcements around the time of the show — Ford said it has plans to share some things around that time — however, the GM representative said that the company has no immediate plans for announcements. Certainly things could change between now and the November show, though. SEMA had previously noted that other exhibitors would help fill in some of the space vacated by these major OEMs. Another OEM, Volkswagen, is returning to the show after an absence, which will also help with the display deficit.

2020 GMC Sierra Review & Buying Guide | The same but different

For the most part, the 2020 GMC Sierra 1500 and the Chevy Silverado are very close siblings. And with the more modestly equipped Sierra SLE and SLT models, choosing between the equivalent Chevy and GMC largely comes down to styling preference and whether you got a better deal at the GMC dealer. They’re almost identical twins. Almost. Because despite the shared DNA, there are differences in terms of model choice. There's no GMC equivalent to the cheaper Custom Trail Boss, for instance, but there is the high-dollar off-road-oriented AT4 that goes beyond the Chevy LT Trail Boss with more equipment and the availability of GMC's unique MultiPro tailgate and CarbonPro carbon fiber bed. Those are also available on the GMC Sierra Denali, which further differs with an adaptive suspension not offered by Chevrolet that seriously improves the ride comfort and handling composure of GM's full-size trucks. GMC therefore makes a compelling case for itself if you're willing to spend more for your truck, but having said that, the range-topping Sierras also don't go above-and-beyond in the same ways as the ritzy Ram 1500 and Ford F-150 trim levels do to provide a proper luxury truck experience. The new Duramax diesel engine at least stands out, but otherwise the Sierra doesn't offer a lot that others can't match or better (even within the GM family). What's new for 2020? CarbonPro Editions debut for the AT4 and Denali trim levels. These include the CarbonPro composite bed and a Kicker audio system in the MultiPro tailgate. The AT4 versions also gets some unique exterior trim. Mechanically, a 10-speed automatic is now paired with the drivetrain combo of 5.3-liter V8, Dynamic Fuel Management and four-wheel drive. Aiding visibility are newly available trailer tow mirrors, a bed-view camera, and a high-def 360-degree camera system with trailering elements.  What's the interior and in-car technology like? Like its Silverado sibling, the Sierra's cabin is its least compelling and competitive attribute, falling far behind the Ram 1500 and Ford F-150 in terms of quality and design. The dash is drab and frankly ugly in every trim level, but the cabin is particularly damning in the Sierra Denali. Its black vinyl "stitched" onto the black dash and some token strips of wood trim slapped onto the center console and doors just aren't enough to create the sort of high-dollar ambience truck buyers can find elsewhere.
