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.

GM issues stop-delivery for 2015 Chevrolet Colorado and GMC Canyon

General Motors is issuing a stop-delivery order for its latest midsize pickups, the 2015 Chevrolet Colorado and GMC Canyon, because the driver's side airbag might not be wired correctly. The total number of vehicles affected is still being determined.
According to the statement from GM, the problem, "affects the vehicles' two-stage airbag system by reversing the deployment sequence and disrupting the deployment timing of the driver airbag stages." That means in an accident the bag may not work correctly.
Most of the affected trucks are still on the assembly line, in transit or unsold at dealers, says GM. Until a way to repair the problem is found, customer deliveries are stopped. However, "a small number" of them are in the possession of buyers. GM is contacting these people by phone and by FedEx letter to have the vehicles returned to dealers. In the meantime, they'll be given a loaner to drive.

2017 GMC Acadia coming to Detroit Auto Show

Well, it's about time. If there's one group of vehicles that are in serious need of an update, it's the GM Lambda crossovers. You know, the Chevy Traverse, GMC Acadia, and Buick Enclave. They're super old. Good thing, then, that the brand-new Acadia is coming to the Detroit Auto Show next week, as evidenced by this teaser image found on the company's Facebook page. There's not much to see here, except for an LED taillamp signature on what appears to be a much cleaner rear end. We expect the three-row CUV to feature all of the latest GM tech, including a robust infotainment system with Android Auto and Apple CarPlay. V6 power and optional all-wheel drive makes sense here, too, though we won't rule out some kind of four-cylinder option. When GM launched the Lambda crossovers, the Acadia arrived first in late 2006, alongside the now-discontinued (but still very much present in the current Acadia) Saturn Outlook. The Buick Enclave came next, and the Chevy Traverse arrived after that. It's unclear if GM will stick with this rollout plan, of course, but one thing's for sure: all-new versions of these CUVs cannot come soon enough. Related Video:
