2020 GMC Sierra HD offers loads of tech

The 2020 GMC Sierra HD has finally been revealed, and it's a heck of a lot more subtle than the Silverado HD. Whereas the Chevy went with a wildly exaggerated version of the split grille and headlights the truck is known for, the Sierra simply builds on the 1500 model's design with an expanded grille that doesn't appear to be as tall or wide as the Chevy's. That's not to say it looks unimpressive, though. It's still got a massive fascia, it's just not as extreme as the one with a bowtie on it. With the Sierra's unveiling, we get more details about the powertrains available on the heavy duty GM trucks. The 6.6-liter turbocharged Duramax V8 makes 445 horsepower and 910 pound-feet of torque. That's the exact same output as the engine in the old models. But this time, the engine will be mated to an Allison-branded heavy duty version of the GM 10-speed transmission. A gas engine will also be available, but GMC hasn't revealed details on it yet. The new Sierra boasts a range of new features, some that are unique to it, and some shared with the Silverado. A shared feature is the new steps in the bed sides that are standard on all Sierra HD models. Unique to the brand is the MultiPro tailgate with fancy drop-out step. This tailgate will be available on all trims, and it's standard starting with the mid-level SLT. There are some useful visibility features being shown on the new Sierra, too, such as an available trailer camera system with 15 possible viewpoints, and it can virtually show the rear view on the screen as if there wasn't a trailer in the way. GM's rear-view mirror screen also makes an appearance. An AT4 off-road trim will be available on the new Sierra HD. It has slightly different styling with dark grilles and trim. Off-road upgrades include reworked springs and shocks, skid plates, standard all-terrain tires and a locking rear differential. Pricing has not yet been announced, but the truck goes on sale this summer. Details on prices as well as further specifications will likely be announced near the on-sale date.

GM reportedly developing 2.5-liter turbo four-cylinder

General Motors is allocating a massive amount of resources to developing electric technology, but it's not forgetting about the gasoline-powered cars that make up the bulk of its sales. It's reportedly designing a new 2.5-liter turbocharged four-cylinder engine based on its 2.7. Citing "sources familiar with the matter," enthusiast website GM Authority wrote that the 2.5-liter four is "in [the] final stages of development," meaning it should be announced sooner rather than later (assuming the report is accurate). Technical details are few and far between as of writing. The publication learned that the 2.5 will be part of the Cylinder Set Strategy (CSS) family of engines and that it will be mechanically related to the 2.7-liter currently found in the Chevrolet Silverado 1500, among several other models. It will feature dual overhead camshafts. It's too early to tell which models the 2.5-liter four-cylinder will end up in, or how much power it will generate. The output will likely depend on the application. For context, the 2.7 delivers 310 horsepower at 5,600 rpm and 348 pound-feet of torque between 1,500 and 4,000 rpm in the Silverado. In the smaller Colorado, it provides anywhere between 237 and 310 horsepower depending on the trim level selected. While this is pure speculation, our crystal ball tells us the engine will end up powering crossovers. It's an easy deduction to make. We can't imagine it will be offered in the Silverado, and seeing it in the Colorado is unlikely because its entry-level engine develops 237 horsepower; there's likely not much of a market for a midsize truck with 200 or so horsepower. Putting it in the Corvette wouldn't make sense and the Camaro has nearly reached the end of its life cycle without a successor planned. This leaves us with Chevrolet's range of crossovers, like the Equinox, as well as their GMC-, Buick-, and Cadillac-branded counterparts. We're not discounting the possibility that the cars set to receive the 2.5 haven't been unveiled, but those are likely crossovers, too; the odds of seeing another big Chevy sedan are very, very low. General Motors hasn't commented on the report, and it hasn't publicly announced plans to expand its CSS family of engines. If the report is accurate, we should learn more about the new turbocharged, 2.5-liter four-cylinder engine in the not-too-distant future.

2018 GMC Sierra Denali 1500 Drivers' Notes | Chrome cowboy

No matter how much automakers want to charge for trucks, it seems there will be a market. Ford, Ram and GM all have trucks that can push well over $60,000, something that would sound unbelievable even 10 years ago. That brings us to the 2018 GMC Sierra Denali, GM's top dog in the pseudo-lux truck segment. It's packed with tons of goodies and features, but it's starting to feel a little long in the tooth. Still, GM trucks are some of the best selling vehicles in America, so it seems customers don't mind the age. Associate Editor Reese Counts: I've said it before, but I'm not a big truck guy. Give me a Colorado or Tacoma over any of the full-sized behemoths rolling off assembly lines today. Still, I do enjoy taking one home on occasion, especially one as comfortable and well appointed as this Sierra Denali. There's leather and wood and contrasted stitching throughout. The problem is that it's all a veneer over what's becoming an extremely dated truck, though a new one is on the horizon. There's one big thing that truly bothers me about this truck: no keyless entry or ignition. Don't get me wrong, I have no problem doing things the old-fashioned way, but when literally every other competitor at this price has keyless as standard equipment, the fact that GMC (and Chevy for that matter) still require you to pull out a fob and stick a key into an ignition is really glaring. It has to have something to do with the platform, as GM makes plenty of vehicles that don't require a key. One thing that doesn't feel dated is the ride and performance. This truck is equipped with GM's Magnetic Ride Control, and it works wonders for the Sierra's comfort. It would be even better if it wasn't wearing some gaudy 22-inch wheels, but it's still better than a lot of trucks out there. The powertrain, too, is a nice bright spot. The eight-speed automatic is smooth and never feels lost in the hunt for better fuel economy. The 6.2-liter V8 feels strong, and power comes on smooth and easy. Ford's EcoBoosts may win on fuel economy, but there's nothing like a big, burly V8. Senior Editor, Green, John Beltz Snyder: Despite the massive amounts of guilt I feel every time I put my foot to the accelerator, big trucks — something of which I used to steer well clear — are beginning to warm up on me. That being said, others have made more of an impression on me than this Sierra.
