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.

2022 Rivian R1T vs. 2022 Ford F-150 Lightning vs. GMC Hummer EV Pickup | How they compare on paper

The 2022 Rivian R1T has arrived, ushering in the era of the production electric pickup truck. The Rivian reviews are in, and spoiler alert: They're pretty good. Curious how the new battery-powered truck stacks up to its forthcoming competitors? Well, you've come to the right place. Rivian beat all of Detroit's big automakers to market in the half-ton segment, but probably not by the margin the startup would have liked. Ford's answer is the F-150 Lightning, which is due to enter production early next year, coming hot on the heels of GM's first entry into the space – the GMC Hummer EV pickup – which is scheduled to come off the line late this fall. While all three are pickups, they're aimed at distinctly different buyers, as a perusal of their specifications will reveal. Let's have a look, shall we?   Disclaimer: Before we dive in on this one, we'd like to note that while we've made our best effort to verify the specs provided, the Rivian is brand-new and the others are still in the prototype phase. Some of these figures may be inaccurate or may simply change before production. This is all hypothetical until you can actually cross-shop them anyway, right? Cool. End disclaimer. Let's start with the powertrains. They're all battery-electric trucks engineered on a modular rear-wheel-drive configuration engineered to accommodate (theoretically, anyway) up to four electric drive units. Rivian actually makes the most use of this with a quad-motor setup producing 835 horsepower and 908 pound-feet of torque with its high-output initial model. GMC's three-motor Hummer has the R1T beat with its estimated 1,000-horsepower output, while Ford's (also three-motor) comes in with a far more modest 563 horses. This is an excellent illustration of our above point that these are not all engineered for the same crowd. Ford's F-150, which comes in at a lower price point, is meant to be far more mainstream, as its power output suggests.  This theme continues when we look at the dimensions. Despite the image "Hummer" may conjure, GMC's entry actually needs the shallowest parking space. The Rivian is right behind it, with the work-truck-spec Ford extending more than a foot longer than either. What the Hummer lacks in length, it makes up for in girth. It's the widest by a good 5 inches. The Rivian is only slightly pudgier than the F-150, but it's much closer at that end of the scale.

Big And Boxy Might Be Best
As immense fans of the Back to the Future trilogy, we sometimes like to envision an alternate timeline in which General Motors had killed off GMC and kept Pontiac instead. The G8 GXP would still be on the road handily beating German sport sedans costing twice as much, while the lowly G3 would morph into a true subcompact-killer based on what is now the Chevrolet Sonic RS. While we're at it, let's go ahead and imagine the G6 has become the best-selling car in the US and the Torrent crossover is selling 20,000+ units per month. Far-fetched, we know.
The thing is, these fanciful statements would have to be true to make the case against keeping GMC. Pontiac may have offered more excitement than GMC, but money talks, and a full line of trucks, crossovers and SUVs have made a lot more money for GM than the arrowhead brand ever did. How much? As we learned last month, about two-thirds of GM's global profits came from its fullsize trucks, and GMC's trucks typically have thicker margins than their Chevrolet counterparts.
