2019 GMC Sierra Denali Drivers' Notes Review | Half measures

Associate Editor Reese Counts: This truck feels a full generation behind the competition. It's a half measure that feels more like a mid-cycle refresh than a whole new truck. There are a few high points: the 6.2-liter V8 is great (if thirsty) and the bed is wider than anything else in the class. The tailgate, too, is nifty, though some might write it off as a novelty. I also dig the tech, particularly the infotainment system and heads-up display. Ram might brag about its giant touchscreen, but I think I actually prefer the GMC's user interface. The rest can be summed up with a series of shoulder shrugs. The Sierra finally looks different than a Silverado, but I wouldn't call it handsome. The interior is spacious, but I'd knock the design and materials in a $45,000 truck, much less one approaching $70,000. It's not Toyota Tundra levels of terrible, it's just plain, cheap, and not nearly as space efficient as the Ram. It feels like GM's not even trying to move the needle with this truck. The more time I spend behind the wheel, the less I like it. Assistant Editor Zac Palmer: I got to spend a lot of seat time in this 2019 GMC Sierra Denali, and I came away generally unenthused by GM's most luxurious truck. We harp a lot about how expensive pickup trucks are these days, and this one's near $70,000 price tag is just the same. When you step inside a similarly-specced Ram, it feels like it's worth its price. When I step out of a Silverado and into a more expensive Sierra, I want to feel like it's money well spent. This Sierra Denali does not. Beyond the leather seats and a few small pieces of wood trim, it's hard, black plastic galore. What makes it all the more frustrating is that GM has most of the tech and features it needs (solid infotainment, 360-degree camera, wireless phone charging and the rear camera mirror is genuinely awesome). The presentation just comes off as dated from the start. It's a shame, because I have a strange affinity for how this truck looks from the curb. The sharp angles, brash styling and "tough truck" attitude is appealing to me. I like stomping on the gas and letting the 6.2-liter torque monster under the hood loose. But man do you pay the price for using that engine. Over a few hundred miles of driving I ended at a dismal 15 mpg reading on the trip computer — the saddest part of this was knowing these were mostly highway miles.

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.

GM reportedly recalling select 2014 Silverado, Sierra pickups over airbag issue

General Motors is recalling 843 2014 Chevrolet Silverado and GMC Sierra Crew Cab pickups, due to a fault with the vehicle's airbags. According to GM, the airbags may not inflate properly in the event of a crash. There haven't been any crashes or injuries associated with this recall, which is always good. Naturally, repairs will be free of charge, and GM will begin contacting affected owners soon.
GM has a lot hanging on the 2014 Chevrolet Silverado and GMC Sierra. Not only is it banking over $12,000 per vehicle on these trucks, as reported by Automotive News, but GM is counting on the Sierra and Silverado to take the fight to cross-town rivals Ford and Ram. The F-150 and Ram 1500 have been on a tear over the past few years, with fresh updates, advanced powertrains, and plenty of solid press while the GM trucks have been waiting for the 2014-model-year upgrades.
It's still entirely too early to judge the Sierra and Silverado, particularly as those 843 recalled trucks make up barely two percent of the over 40,000 units moved so far. But, as AN rightly states, these trucks are the most important vehicles to come out of GM since bankruptcy, with about 60 percent of global profits relating to pickups and SUVs. Starting an introduction of such a big product with a recall, however small, is not the preferred way to do things.
