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.

GMC Canyon Denali Interior Review: THE luxury midsize truck

Over the past couple of years, GMC has been getting serious about being more than just a rebrand of Chevy trucks and SUVs. The same goes for the luxury Denali line. Among the beneficiaries of this push for differentiation is the latest Canyon. On top of only being available with the wide-track layout and the most powerful engines, it gets a Denali trim that is unequivocally the most luxurious midsize truck in the segment. The GMC Canyon Denali could even be described as a luxury midsize truck, of which there are no others. And it all comes down to what GMC has done with the interior. Open the door, and the upgrades are immediately obvious. There's leather everywhere. It's on the dash, the door panels, center console and doors. And it has nice details with the perforation and quilted stitching. The seatbacks get embroidered Denali logos and contrasting leather panels, too. The feel is more rugged than supple, but it is a truck after all, and the materials feel like they'll wear nicely.  Then you notice the wood trim. The real wood trim. It's subtle, just adorning a strip along the top of the dash and the front door panels, but the light brown color stands out against the black leather and plastic elsewhere. It's got a natural, open-pore finish that highlights the material, and the strip in the dash gets extra laser-cut details. The branding consisting of DENALI, some stylish strakes and the coordinates of Denali, the mountain, are crisp and clear. Throw in plenty of shiny chrome, and the same quality-feeling buttons and knobs (the knurling details on the knobs are particularly nice), and just on trimmings alone, it's obvious the Denali is the most plush little truck. The seats themselves are solid, though not particularly exceptional. The front seats are a bit flat, but they're also very roomy. On the Denali, the driver's seat has eight-way power adjustability with memory, and the passenger has six-way power adjustability. Heating and ventilation are included, too. Leg, head and shoulder room are also all excellent up front. The rear seat, like the rest of the segment, has enough room for adults, though legroom is a tad tight, with knees likely brushing the front seat backs. The seat bases in the rear are split with storage underneath, although it's not particularly useful. Besides its meager volume and awkward shape, much of it is taken up with the jack.

GM will recall 3.5 million pickups and SUVs to fix brake issue

WASHINGTON — General Motors Co is recalling 3.46 million U.S. pickup trucks and SUVs to address a vacuum pump issue that could make braking more difficult and increase the risk of a crash. The recall, which covers 2014-2018 model year vehicles, including some Cadillac Escalade, Chevrolet Silverado, Chevrolet Tahoe, GMC Sierra, Chevrolet Suburban and GMC Yukon vehicles, was triggered because the amount of vacuum created by the vacuum pump may decrease over time, GM told the National Highway Traffic Safety Administration (NHTSA) in documents posted Wednesday. NHTSA opened a preliminary investigation into the issue in November 2018, and said it had reports of 9 crashes and two injuries related to the issue. It provided GM in July with additional field reports that prompted the automaker to open an investigation. The company did not immediately say on Wednesday how many injuries or crashes are linked to the issue but said it could impact braking in "rare circumstances." GM said dealers will reprogram the Electronic Brake Control Module with a new calibration that will improve how the system utilizes the hydraulic brake boost assist function when vacuum assist is depleted. GM said the vacuum assist pump, which is lubricated with engine oil that flows into the pump through a filter screen, can in some cases lose effectiveness over time, as debris such as oil sludge can accumulate on the filter screen. GM told NHTSA that prior model years used a different brake assist system design, and vehicles manufactured after 2018 were not equipped with the affected pump design. Recalls Chevrolet GM GMC
