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.

Meet Alex Archer, the engineer behind GM's power-sliding center console

In 2009, a GM manager complained to a 59-year-old GM technician about the hassle of retrieving items from a pickup truck bed after driving shifted the cargo. In two days, the tech had come up with the ideas that, ten years later, would debut as the MultiPro tailgate. The engineering teams kept the tailgate secret in part by hiding mock-ups in a locked storage closet in GM's Vehicle Engineering Center in Warren Michigan for two years. A piece in the Detroit Free Press reveals that another storage closet in Warren would play the same role in a different cloak-and-dagger operation, this time for the power-sliding center console in GM's new full-sized SUVs. During a meeting in early 2017, bosses gave the job of the console's creation to 24-year-old design release engineer Alex Archer, just two years out of Stanford University with a degree in engineering and product design.  This time, the catalyst for the feature was an internal GM think tank called co:lab, where employees suggest ideas. Execs gave Archer the task because "They needed someone willing to ask a lot of questions," her 36-month mandate to produce a six-way console that could be a standard cubby or a gaping maw able to swallow four gallon jugs or hide a secret compartment. Clearly, she succeeded. It took Archer and the team nine months to devise a prototype, another six months to get the green light for production. As with the tailgate, the team working on the console grew to include designers, production engineers, and suppliers. Archer, now 26, shepherded the process, and her name is on the patent. "It took a ton of people, I'm just somebody who stuck with it the whole time," she said. GM like her work well enough to produce the "Day in the Life" segment above, five months before the world would hear about the console. Archer's path to engineering was as unlikely as getting the job for the console. She had entered Stanford with plans to be a doctor. But an innovation class during her freshman year, and a sophomore summer spent helping her grandfather rebuild a 1937 MG engine recharted her course. Her grandfather told her, "You know, you could be an engineer for a car company." Consumer reaction to Archer's work won't be far off, the SUVs slated to hit dealerships soon. Meanwhile, she's busy on something that could be just as intense as the console: Restoring a 1955 Packard Clipper in her garage. Head to Freep to check out the story of Archer and the console.

Chevy Colorado configurator goes live as GM touts fuel efficiency

While the news of today is destined to be dominated by a certain plucky Japanese roadster, props to Chevrolet and GMC for announcing its own significant bit of news about their newest pickup twins, the midsize Colorado and Canyon. The two GM-owned brands announced that the twins' 3.6-liter V6 will return up to 26 miles per gallon on the freeway.
To get such efficiency from the 305-horsepower mill, you'll need to live without four-wheel drive and be okay with a max city fuel economy of 18 mpg. The combined rating for the 2WD model sits at 21 mpg. Adding four-wheel drive drops the city and combined ratings by one mpg, while the highway rating dips from 26 to 24 mpg.
As for the twins' eagerly anticipated 2.8-liter diesel engine, it's destined for model year 2016, meaning we've got a ways to go before its efficiency and output are certified.
