Chevrolet Silverado, GMC Sierra could get independent rear suspension

The Chevrolet Silverado and the GMC Sierra could reportedly receive a variant of the four-link independent rear suspension found under the new Tahoe and Suburban. While that's not a surprise, a recent report suggests electrification, not comfort, convinced General Motors to make the change. Replacing the time-tested solid rear axle with an independent suspension will improve comfort, handling and off-road prowess, while adding weight, and likely making the trucks a little bit more expensive. It's a fair trade-off, but GM Authority learned the real reason for the swap is that at least one of the pickups will spawn an electric model, and it's more difficult to package a bulky battery pack around a solid rear axle. The independent rear suspension takes up far less space, even if it has more moving parts. General Motors will build its first regular-production electric pickup on an evolution of the Silverado's T1 platform named BT1, according to the same source. The b stands for -- you guessed it -- batteries. The firm reportedly doesn't want to make two suspensions for cost reasons, so the independent setup will come standard regardless of whether the truck runs on gasoline, diesel, or electricity. As a bonus, Chevrolet and GMC could choose to offer their T1-based trucks with Magnetic Ride Control or an air suspension, options available on the 2021 Suburban and Tahoe. The independent rear suspension will also find its way to the next-generation GMC Yukon due to be revealed January 14, and to the 2021 Cadillac Escalade scheduled to make its debut February 4. The long-rumored, born-again Hummer will get it, too, because it will arrive as an electric model built on the BT1 platform. It's worth noting none of this is official, and General Motors has remained quiet about what's next for its new suspension design, and what will be under its electric truck's sheet metal. If the GM Authority report is accurate, the Silverado (pictured) and the Sierra could ditch their solid rear axle for the 2021 model year. The change will likely be accompanied by other tweaks inside and out. Featured Gallery 2019 Chevrolet Silverado 1500 View 16 Photos Chevrolet GMC Truck

REWIND: Watch the GMC Hummer EV live reveal right here

It has been a long wait to see the GMC Hummer electric pickup truck, which was teased way back at the Super Bowl in February of this year. And that wait ends tonight at 8 p.m. eastern time when GM pulls the covers off the truck. You can see the whole reveal right here, or during the World Series on Fox or "The Voice" on NBC. For everything we know about the truck, go to our reveal post here. The truck should be impressive. GMC has previously announced it will have up to 1,000 horsepower, and it will have a variety of fun features such as removable roof panels and four-wheel steering that can move the truck sort of sideways with "Crab Mode." The GMC Hummer will also be available in pickup and SUV forms. So be sure to tune in tonight for one of the biggest (figuratively and literally) vehicle reveals of the year. And keep an eye on Autoblog for all the latest on the Hummer and other vehicles.

2020 GMC Acadia AT4 Review | A soft-roader in steel-toed boots

For carmakers today, the perfect lineup would be focused almost entirely on trucks and crossovers, favoring profitability at the expense of diversity. Just look at FCA’s Ram and Jeep showrooms. In the General Motors portfolio, that brand is GMC, with not a car to be found in its lineup and several body-on-frame offerings meant to take a serious beating. It should be a license to print money. But a lineup of trucks and SUVs isnÂ’t enough. Some folks want the rough-and-tumble edge of an off-road vehicle, albeit one that can still credibly serve duty in the school pickup line. Enter the AT4 trim level, an off-road package that spans the gap between the GMC's upscale professional image and the off-road oriented buyer. The 2020 GMC Acadia AT4 is the latest member of the family AT4 slots in between the mid-grade SLT and the range-topping Denali, but simply saying itÂ’s the second-most expensive Acadia variant isnÂ’t really doing it justice. If the SLT trim is understated, and the Denali trim opulent, the AT4 trim promises ruggedness and adventure – even if it canÂ’t deliver it.  The Acadia is definitely a soft-roader and AT4 doesnÂ’t do much to change that – itÂ’s effectively an appearance package. It adds a unique grille, 17-inch wheels and AT4 badges — all blacked out — plus a set of Continental TerrainContact A/T tires engineered to offer a comfortable ride while still enabling some off-pavement excursions. There are several unique interior treatments as well, including “AT4” embroidery on the seats, regardless of whether you go with the base upholstery or the upgraded perforated leather ($1,000) that was added to our test vehicle. Note that we didnÂ’t mention anything beyond the small wheels and meaty tires that would actually make the AT4 any better off pavement. ThereÂ’s no extra ground clearance (it remains a meager 7.2 inches), low range 4x4 system or suspension enhancement to be found here. This would be a departure from other GMC AT4 models, including the Sierra 1500 and upcoming 2021 Yukon, which get extra ground clearance, underbody protection and a rugged suspension, but it won't be an outlier. The similarly soft-roading Terrain AT4 has already been announced.  Yet, off-road models tend to get hammered with on-road handling and ride quality criticism and here's where the Acadia AT4 being more of an appearance package pays off.
