2022 GMC Sierra Super Cruise First Drive | Now with trailering and automatic lane-changing

Although the updated late-model year 2022 GMC Sierra is still a little ways off (In fact, it hasn't even been revealed), we've had an opportunity to try one of its headlining features: Super Cruise. But it's not quite the Super Cruise you know from the current Cadillac line. The new Sierra will be getting a newer version with two features: the ability to execute lane changes and passes automatically, and the ability to operate with a trailer. We tried the system at GM's proving grounds in Milford, Mich., and our test vehicles were 2022 Sierra prototypes. Though the trucks themselves are early examples with features not finalized, GMC representatives said the Super Cruise system is pretty much finished. The system uses close and long-range radar sensors at the front and a new set of radar sensors at the back, plus the truck's various cameras. It also utilizes the mapping data that GM has accumulated for the system to ensure it operates on approved roads and has detailed information about where the car is. Now, the first new feature enabled by the updated Super Cruise is the automatic lane-change system. The current system can change lanes on its own, but it must be prompted by a press of the turn signal. That feature remains intact, but now, if you approach a slower vehicle on a multi-lane highway, Super Cruise can check the lane next to you to see if it's safe to merge, change lanes, and then return to the original lane once the slow-moving vehicle has been passed. This is where those rear radar sensors come in. We tried it three times on GM's big banked oval course, and it did it impressively smoothly. It was able to make the decision proactively, too, making the decision to change a good distance before we were on top of the slow moving car. Oh, and of course, because this is Super Cruise, it all happened without us having to touch the wheel. Our automatic lane change test was followed by trying Super Cruise with a trailer. Now, it's important to note that the automatic lane-changing functionality won't work with a trailer. This is because that function depends on a set of radar systems at the back of the truck that are blocked by a trailer. Apart from that, the rest of Super Cruise's functions still work just fine. To make this possible (and safe), the system is able to estimate the weight of the trailer and adjust following distance accordingly, allowing it to safely slow down as needed.

GM exploring ways to raise half-ton Duramax diesel tow rating

Lots of truck owners cheered when GM announced fuel economy numbers for the 2020 Chevrolet Silverado with the 3.0-liter Duramax diesel inline-six. Even after Ram let loose its EPA mileage ratings for the 2020 Ram 1500 EcoDiesel, the Chevy oil-burner still took the trophy. The victory was years in the making, GM engineers spending an entire four-year development cycle refining the LM2 Duramax to increase mileage. The tradeoff, as well all know by now, is towing; the Duramax in half-ton duty pulls a maximum 9,300 pounds in the Silverado. Rivals across town can do more, the Ford F-150 PowerStroke rated at 11,500, the Ram 1500 EcoDiesel game to pull 12,560. GM engineer John Barta told Muscle Cars & Trucks that more hauling chops could be on the way, explaining, "We’re actually looking at upgrading some of the materials around (the engine bay) to see if we can maybe raise our tow rating." Engine bay materials are at issue due to thermal complexities underhood. John Barta, GM's assistant chief engineer of diesel engine controls, said the Duramax's inline-six configuration allowed engineers to get emissions hardware like the combined selective catalytic reduction, diesel oxidation catalysts, and diesel particulate filter unit closer to the engine, where it heats up quicker, getting emissions down quicker. But that filter puts another heat source in those confines, enforcing a cap on the tow rating to keep the engine and other systems from overheating. "If you look under the hood," he said, "youÂ’ll see a significant amount of silver ‘moon tapeÂ’ around to make sure things arenÂ’t getting overheatedÂ… if we were to go up in higher towing, which we can, we start impacting the possibility of deteriorating some of the components.” There isn't much space for more grille, so swapping for a better grade of "moon tape" or a different kind of material could reduce engine bay heat, extracting a higher tow rating in the process.  It's important to note a point Barta's been making for months about the Duramax figures, though. "Even though itÂ’s nice to brag about big numbers, in reality, light duty customers are not towing that large with their trucks," and, "We do know that (95 percent) of our light duty customers donÂ’t tow over 9,000 pounds." On our First Drive of the 2020 Silverado diesel we called out the tow rating, but emphasized that the Chevy and GMC have more important challenges to overcome.

2017 GMC Canyon Denali brings the bling

Denali is an incredibly important part of GMC's product strategy. It takes very little effort to create a Denali variant, and these models retail for big premiums over the models on which they're based. So if you're GMC, it makes sense that you'd want to create a Denali version of every product in your range. That in mind, enter the 2017 Canyon Denali. GMC's midsize pickup gets all of the usual Denali trimmings, including a new grille, chrome trim, 20-inch wheels, and the necessary badging. Inside, there's a unique instrument panel, Jet Black leather, heated and cooled seats, and again, Denali badges abound. GMC says the Canyon Denali will be offered exclusively in the crew cab body style, with either the 3.6-liter gasoline V6 or 2.8-liter diesel engine. Have a look at the fancy truck in our gallery above, and scroll down for GM's official press blast. GMC Introduces 2017 Canyon Denali Exclusive design cues, content elevate industry's first premium midsize truck DETROIT, Tuesday, Nov. 17, 2015 – Denali is the ultimate expression of GMC's professional grade style, luxury and capability – and it is coming to the Canyon midsize truck. The 2017 Canyon Denali is being introduced today, ahead of its public debut at the Los Angeles Auto Show. It goes on sale in late 2016. "Canyon is the segment's first and only premium midsize truck, offering unparalleled capability and efficiency matched with maneuverability and refinement," said Duncan Aldred, vice president of GMC Sales and Marketing. "The all-new Canyon Denali builds on that award-winning combination with the distinctive styling, luxurious interior and elevated content that has defined the Denali nameplate since its introduction nearly 17 years ago." Like all Denali models, the new Canyon Denali is distinguished with a unique chrome grille and unique wheels – 20-inch ultra-bright-machined aluminum wheels with painted accents. Exterior cues include chrome fog lamp bezels, five-inch-diameter rectangular chrome assist steps, a polished exhaust tip and a standard spray-in bed liner. The Canyon Denali will be offered in six exterior colors. Inside, a Jet Black interior features Mulan leather-appointed seats with perforated, heated-and-ventilated front seats – exclusive content in the Canyon lineup – along with unique instrument panel and console trim; and Denali-logo sill plates and floor mats. Standard technologies include Forward Collision Alert and Lane Departure Warning.
