GM planning to put its fullsize pickups on a big diet, too

General Motors is just coming off a complete redesign of the Chevrolet Silverado and GMC Sierra for 2014, but in the US fullsize truck market, there is no rest for the weary. According to Reuters, plans are already unfurling for both trucks to drop pounds from their curb weight over the next few years, but this will unlikely be able to keep pace with the 700-pound diet targeted for the next-generation Ford F-150, a truck expected to debut late next year.
The biggest weight reduction for these trucks might not be available until the next full redesign, which will likely happen around 2019, but the article says that smaller updates could shave pounds in the meantime. Two examples given include an "aluminum-intensive" version of the Silverado that could shed 250 pounds and debut around the same time as the lighter-weight, aluminum-bodied 2015 Ford, and there is also talk of reducing weight for driveline components such as axles and driveshafts. These changes are all part of an attempt to meet strict new fuel economy standards coming in 2017, targets which will get even tougher in 2025.

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 Canada recalls 159,240 GMC and Chevy trucks for faulty defroster circuit

General Motors is recalling more than 159,000 2014-2019 Chevrolet Silverado and GMC Sierra pickup trucks in Canada due to a potential fire risk. GM says the rear defroster circuit could overheat on trucks optioned with the power-sliding rear window. Thus far, there is no word on the recall's relation to U.S. vehicles. The recall, found by Automotive News, was posted to Transport Canada on June 28, 2019 with manufacturer recall No. N192220470. Included in the 159,240 vehicles are the 2014-2018 Silverado 1500, the 2015-2019 Silverado HD, the 2014-2018 Silverado LD, the 2014-2018 Sierra 1500, the 2015-2019 Sierra HD, and the 2014-2018 Sierra LD. The notice says the rear defroster circuit, specifically on trucks with the power-sliding rear window, could overheat. Because of its placement, this excess heat could cause melting, smoking, or possibly fire, in the worst case scenario. As of now, there is no official word when GM will initiate the recall and there is no official fix detailed just yet. GM suggests that owners, who will be notified by mail if their vehicles are affected, take their trucks to a dealer to remove the rear window defroster fuse as a stop-gap.  Automotive News contacted GM to find out if the problem is also found in trucks sold in the United States, but no definitive statement was made, as the investigation is reportedly ongoing. We will update this space if American vehicles are found to be included in the problem.
