2019 GMC Sierra revealed with CarbonPro bed and new diesel engine

It's only March, and it's already been one hell of a year for trucks. January's Detroit Auto Show saw the reveals of the 2019 Ram 1500, 2019 Ford Ranger and the 2019 Chevy Silverado. The Chicago Auto Show brought new versions of the Toyota Tacoma and Toyota Tundra TRD Pro. Today, we finally got our first look at the Silverado's twin, the 2019 GMC Sierra. The truck features new styling, a new diesel engine and — on the Sierra Denali — a carbon fiber bed. As with every new full-size truck, the Sierra is larger than the outgoing model in almost every dimension, though exact dimensions haven't been revealed. For reference, though, the Chevy Silverado's bed is 7-inches wider than before. The new Sierra grille is more upright than before and features new C-shaped lighting. The Denali gets LED headlights, tail lights and fog lights. Both SLT and Denali trims get unique 22-inch wheels. As we saw in spy photos, the Sierra's interior is mostly just a copy of the Silverado's with some chrome accents sprinkled throughout. If you like the current truck interiors, you'll be pleased with the new model. Those hoping for a wholesale change will be left wanting. The big improvements inside include a full-color heads-up display, trailer hitch assist apps and cameras, and the rear-camera mirror found in models like the Chevy Traverse and Cadillac CT6. Safety and convenience features include a surround-view camera, blind-spot monitoring, pedestrian detection and low-speed automatic braking. Like the Silverado, there's been a significant effort to cut weight in the new Sierra. The 2019 model loses as much as 360 pounds compared to the current truck. It uses aluminum for the doors, hood and tailgate. Steel is still used for the fenders, roof and standard cargo box. The Denali, however, gets the real surprise here. Available only on the top-tier trim, the bed box will be constructed of carbon fiber rather than steel, saving 62 pounds. Carbon fiber only replaces the steel inner panels and floor. GMC says the carbon fiber will also help scratch and corrosion resistance. SLT and Denali models also get a new MultiPro tailgate. This is unique to the Sierra and separate from the Silverado's power assist unit. A new feature that helps one get into and out of the bed using an assist handle. The tailgate step has a maximum weight capacity of 375 pounds. There multiple positions that allow customers to extend the bed, or drop the center vertically to gain easier access to the back.

2025 GMC Terrain fully revealed in spy photos

A couple of months ago, GMC teased the 2025 Terrain compact SUV and said there'd be a reveal sometime this year. We're still waiting on the official reveal, but in the meantime, a spy photographer caught the GMC out and about without any coverings. So this is an early look at the Terrain, both in AT4 and Denali trim levels. Being a mechanical twin to the recently revised 2025 Chevy Equinox, there are some similarities in the roofline, the prominent C-pillar and the window lines, but beyond that the Terrain continues to be solidly distinguished from the Chevy. The front has GMC's more vertical headlights and tall grille, with the latter getting a unique black surround. The fender flares are given more prominence, particularly from the signature amber marker lights over each wheel, and there are subtle taillight and bumper changes. There are design differences between the AT4 and Denali, too. The AT4 has black contrasting flares and bumpers, whereas the Denali has body color pieces. And the AT4 has tow hooks and smaller wheels with all-terrain tires. The Terrain really differentiates itself from the Equinox inside, though. It trades the more organic, trapezoidal Chevy design for the crisp, rectangular looks of larger GMC models. Complementing the look is the touchscreen in portrait layout compared to the Chevy's landscape unit. We don't know for sure whether this screen will be standard across the lineup (the photo is of a Denali), but considering GM's willingness to include big screens in all its models, we wouldn't be surprised if this is included even on base Terrains.  Underpinning the Terrain will be the same new platform as Equinox, and almost certainly the same turbocharged 1.5-liter four-cylinder with 175 horsepower. Front-wheel drive and all-wheel drive should be on offer, with the former getting a CVT and the latter an eight-speed automatic. The AT4 model clearly has reworked bumpers for better approach and departure angle than the standard Terrain, and probably has some additional light protection. We'll be curious if GMC offers a twin-clutch rear differential for some locking and torque-vectoring functionality to help it stand out and potentially compete with the likes of high-end Bronco Sport. But that's more in the realm of speculation. We should have confirmation of many of these details and much more soon when GMC officially reveals the Terrain itself.

GM ending stop-sale order on heavy-duty trucks

General Motors responded to an inquiry from Autoblog regarding a stop-sale order on its full-size heavy-duty pickup trucks. Here's GM's official statement. GM is committed to building the highest quality products possible. We paused delivery on a small number of HD pickups with the 6.6 liter Duramax engine last week to finalize an investigation into a potential quality issue. The investigation has been completed and the stop sale will be lifted for the small number of vehicles at dealerships.Customers can be assured GM’s heavy duty pickups are covered by a 5 year/100,000 mile powertrain warranty. The original article continues below. General Motors has reportedly sent its Chevrolet and GMC dealers a stop-sale order that applies to some examples of the 2022 Silverado HD, the 2022 Silverado MD, and the 2022 Sierra HD. The units affected by the stop-sale order may develop an engine-related problem. Citing anonymous sources, website GM Authority wrote that the Duramax 6.6-liter turbodiesel V8 in the affected trucks can hydrolock, which means liquid could enter the cylinders and cause a substantial amount of damage. The report does not specify where the liquid would come from; hydrolocking can happen by driving through a deep puddle of water, for example, but a large amount of coolant can cause it as well. The publication adds that the stop-sale order was assigned internal reference number N222362910. It also notes that the trucks included in it can't be sold, delivered to buyers, traded with another dealer, sent to auction, or even used for demonstration purposes until further notice. Earlier in April 2022, GM Authority reported that General Motors planned to buy back an unspecified number of Silverado HD and Sierra HD trucks due to quality-related issues with the 6.6-liter V8. Details about the problems experienced by customers haven't been released; all we know is that each truck will be replaced, though the replacement may not have the same equipment due to the ongoing chip shortage.
