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.

2021 GMC Canyon gets AT4 trim and a 'more upmarket' Denali

The AT4 train continues at GMC, with the 2021 Canyon AT4 climbing to altitude in Vail, Colorado, to announce its arrival. The off-road package, teased during the Sierra HD launch last year and already rolled out on the Sierra and Acadia, replaces the Canyon All Terrain trim. The rectangular grille goes away, the new rig picking up a larger, Sierra-like grille with a dark chrome surround and vertically-oriented fog lights. And because nothing says off-road badass like red recovery hooks, of course there's a pair peeking out from under the tweaked lower bumper. Otherwise, all the All Terrain kit carries over, like the tuned suspension with Advanced Hill Descent Control, transfer case skid plate, automatic locking rear differential, and 31-inch Goodyear Wrangler DuraTrac® tires on 17-inch aluminum wheels. Inside, the headrests are embroidered with AT4 logos, and Kalahari stitching is exclusive to this trim. GMC also announced a more polished Denali trim, without providing any photos. The coming pickup adopts a grille with a "more sculpted and layered pattern," plus five-inch chrome assist steps, and 20-inch Diamond Cut aluminum wheels that we'll assume come in a different pattern than the current 20-inch Diamond Cut aluminum wheels. The cabin goes upscale with open-pore ash wood trim and aluminum trim, a new Cocoa/Dark Atmosphere color theme, and unique stitching. Both the AT4 and Denali offer the same two engine choices. There's either the 3.6-liter V6 throwing out 308 horsepower and 275 pound-feet of torque, shifting through an eight-speed automatic, or the 2.8-liter Duramax diesel producing 181 hp and 369 lb-ft, shifting through a six-speed auto. The 2021 trucks will be available later this year, pricing to be announced closer to the on-sale date. The 2020 Canyon All Terrain starts at $37,695, the 2020 Canyon Denali starts at $41,595.
