2021 GMC Sierra 1500 Review | More towing, same truck

The 2021 GMC Sierra 1500 and the Chevrolet Silverado 1500 are close siblings, and they’re getting closer every year. One of the SierraÂ’s previous standout features, the Multi-Pro tailgate, can now be found on the Silverado for 2021, providing even fewer reasons to choose the GMC instead of the Chevy. Really, if youÂ’re looking at the more modest SLE and SLT models, the choice between the two largely depends on styling preference. The Sierra Denali is a slightly different story, as its available adaptive suspension is exclusive to GMC and notably improves both the ride and handling.  Of course, it still can't match the Ram 1500 in either regard, plus the Denali cabin continues to be a rather half-hearted attempt at luxury. Especially considering the genuinely high-lux offerings of Ram and Ford. The gap isn't so huge between the Sierra's lower trim levels and its non-Chevy competitors, but the cabin's design, quality and functionality still leave something to be desired. True, that often isn't a priority for truck buyers, but the Sierra isn't superior in enough other ways to balance it out. It's a capable truck with a compelling variety of powertrains, but it generally just doesn't go that extra mile beyond the competition as well as its Silverado sibling. What's new for 2021? Changes for 2021 are mostly equipment-related, but there were some vital towing and pricing changes made for the new year, too. All 2021 Sierra 1500s come with a suite of new towing tech detailed here. New technologies include a trailer length indicator, jack-knife alert, trailer backup guidelines, and camera enhancements that include a rear side view and cargo bed view. GMC expanded availability of the Multi-Pro tailgate, now allowing folks who opt for the lower SLE and Elevation trims to option it. The AT4 adds new Goodyear Wrangler Territory all-terrain tires and an off-road high-clearance step. Diesel buyers will be delighted to hear that GMC has lowered the price by $1,500 to $995, and raised the trailering capacity by 1,900 pounds to a more competitive 9,300. Maximum towing for the 2.7-liter turbo-four-cylinder is also up by 2,300 pounds to 9,200 pounds. GMC says the increase for the diesel is due to “better-than-expected rear axle durability,” and the four-cylinder is up because GM found the engine possesses “better-than-expected cooling performance.” What's the interior and in-car technology like?

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.

Should heavy-duty pickup trucks have window stickers with fuel mileage estimates?

If you were to stroll into your nearest Chevrolet, Ford, GMC, Nissan, or Ram dealership, you'd find a bunch of pickup trucks. Most of those would have proper window stickers labeled with things like base prices, options prices, location of manufacture, and, crucially, fuel economy estimates. But you'd also run across a number of heavy-duty trucks with no such fuel mileage data from the Environmental Protection Agency. The EPA doesn't require automakers to publish the valuable miles-per-gallon measurement for vehicles with gross weight ratings that exceed 8,500 pounds. That makes it difficult for consumers to compare behemoths powered by turbocharged diesel engines – between one another, and between smaller, gasoline-fueled trucks. Consumer Reports doesn't think it should be this way, and it's spearheading an effort (PDF link) to get the government to require manufacturers to publish fuel economy estimates. In its own testing, CR found that heavy-duty pickups powered by Ford's Power Stroke, GM's Duramax, and FCA's Cummins diesel engines (which doesn't include the Ram's EcoDiesel) get worse fuel mileage than their lighter-duty gas-powered siblings. We're not so sure HD-truck buyers are unaware of this fact – big diesels don't really come into their own until big loads are placed in their beds or attached to their trailer hitches. Under heavy workloads, the diesel trucks will almost certainly return greater efficiency than a similar gas-powered truck. What's more, HD trucks with lumbering diesels in general make the driver feel more confident while towing due to greater torque at low engine RPM than gas trucks. They also offer greater max-weight limits. Still, we agree EPA fuel mileage estimates should be offered for heavy-duty pickups. And we think the comparisons provided by Consumer Reports might be interesting to potential buyers. Click here to see the results of CR's tests, and let us know what you think using the poll below.
