GM confirms 2015 Silverado, Sierra to get 8-speed automatic

When viewed alongside the next Ford F-150 and the Ram 1500, there is one thing that seems to be missing from the Chevrolet Silverado and GMC Sierra. Where the F-150 will rely on turbocharging and aluminum architecture and the Ram sports an eight-speed automatic and an air suspension, the General Motors twins lack a big, calling-card feature. They're very good, very refined trucks, but one could argue that they're not terribly innovative.
And while it might not be as flashy a feature as air suspension or a lightweight skin, the Silverado and Sierra will get their own eight-speed automatic for 2015, a transmission that will be paired with the company's Ecotec3 6.2-liter V8. The new cogswapper will also find its way into the GMC Yukon Denali, but for now, there's no indication why the Cadillac Escalade, Suburban, Tahoe and standard Yukon are being left out.
According to GM, the new gearbox is about the same size and weight as the current Hydra-Matic 6L80 six-speed. By the time the new powertrain combination enters production late this year, the EPA will almost certainly have gotten around to certifying the vehicles' fuel efficiency. Until then, feel free to speculate. The current Silverado with the 6.2 and six-speed auto returns 14 miles per gallon in the city and 20 on the highway. How much do you think the eight-speed will improve those figures? Scroll down for the official press blast from General Motors, and then head into Comments.

2018 GMC Sierra Denali can help you tow without breaking a sweat

Towing a trailer once meant that only those who possessed certain knowledge would be able to go fishing, tow a race car or pull a camper safely. For me, it took four long years of practice working a job behind the wheel of a jacked-up Ford F-250, hauling tons upon tons of mowing equipment for my local parks department, to become proficient. Just how far things have come since then became evident after a recent trip to Utah with GMC, in which we used the half-ton Sierra Denali to tow a set of Polaris side-by-sides through the state. Modern safety technology and a suite of electronic aids make towing simple enough that anyone with a driver's license and something to haul can do it. This revelation came behind the leather-wrapped and heated steering wheel of GMC's outgoing 2018 Sierra Denali. Sitting in the plush, heated and cooled captain's chair, I could barely feel the 6,000 pounds I was towing behind me. Even GMC's smallest full-size truck engine, a 5.3-liter V8 generating 355 horsepower and 383 lb-ft of torque, felt like overkill for what used to amount to a heavy load. With Utah's pristine landscape, the plush confines of the cabin and the uneventful nature of modern towing, mile after mile just streamed by at highway speeds without incident (or excitement). When we finally reached our destination a few hours later, one of GMC's representatives who had chosen to sit in the rear of the cab asked me what I thought about the drive. I pondered for a few minutes and answered with this: "Modern pickup trucks have removed nearly every skill-based variable once associated with towing. I could drive this truck and trailer confidently with just one finger." Consider the near overabundance of towing-assistance systems in the GMC Sierra Denali that I piloted through Utah. Let's start with the most basic of towing skills — something that's now been relegated to the annals of history: reversing a pickup to meet the trailer's hitch. Once upon a time, this required knowing a truck's dimensions and understanding proximity, as well as having a keen eye, a steady foot for both the gas and the brake and the patience to get it right. Now, though, pickups such as the Sierra Denali offer customers a trailer reverse camera system that helps the driver align truck to hitch with pinpoint accuracy.

2019 GMC Sierra 1500 pickup teased on Twitter

GM's half-ton pickup line will be fully rounded up later this week when the new GMC Sierra 1500 is revealed. Though the unveiling is on March 1, GMC has provided a teaser of the new truck ahead of time on Twitter. It shows only the front fascia, but considering the Sierra's history of simply being a badge-engineered Silverado, it's arguably the most important angle of the truck. The teaser confirms a few things we were expecting based on past spy shots. The headlights look much more conventional than the Silverado's rather small units. The Sierra's grille, unlike the Silverado's, will also rise above the tops of the headlights, providing more of a big-rig appearance. We also finally get to see the GMC badge on the front of the Sierra, and it looks like it's an enormous rendition. As for the rest of the truck, previous spy shots have shown the Sierra will have other subtle styling changes from the Silverado. The wheel wells are shaped differently, and the taillights will be unique to the GMC. The interior of the new Sierra will look almost identical to that of the Silverado, with the exception of a few minor trim details. We also expect the Sierra to use the same engine lineup as the Chevy's, which at this point we know will consist of a 3.0-liter turbocharged diesel inline-six, and naturally aspirated 5.3- and 6.2-liter V8s.
