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 will debut in Detroit

With the debut of the Chevrolet Colorado at November's Los Angeles Auto Show, perhaps it was only a matter of time before we saw the small truck's GMC counterpart. That time will be January, as we've received official confirmation that the GMC Canyon will be revived at next month's North American International Auto Show in Detroit.
The news came in the latest issue of the Detroit Auto Show's newsletter, NAIAS Connect. The article hasn't been posted online quite yet, but it details the Canyon as one of the world production debuts slated for the show.
While we've heard rumors that the Canyon would arrive in Detroit, this is our first concrete bit of evidence. As we've detailed before, we expect the Canyon to be stylistically quite different than the Colorado, though the underpinnings will be shared. The teaser image we have above is currently our only look at the new truck. We'll hopefully have more details in the next few weeks as the GMC Canyon draws closer to its official debut.

2015 Chevy Colorado and GMC Canyon order guides reveal added power

General Motors' Fleet Order Guide system is often the canary in the coal mine for interesting changes on new models. The recent guide for the 2015 Corvette unveiled all sorts of changes that weren't yet known about the sports car. Now, it's time for the 2015 Chevrolet Colorado and GMC Canyon to take their bow in the spotlight, and they look worth the wait. The new midsize trucks are getting a touch more power than first thought, as well as some very nice features.
Extended Cab models of both trucks come standard with a 2.5-liter, direct-injected four-cylinder rated at 200 horsepower at 6,300 rpm and 191 pound-feet of torque at 4,400 rpm. That's a bit more than the 193 hp and 184 lb-ft originally reported for the duo. The standard transmission for the extended trucks is a six-speed manual, but the Work Truck trim is also available with an optional six-speed automatic. Towing for the four-cylinder is rated at 3,500 pounds.
Crew Cab models come standard with a 3.6-liter V6 with 305 hp at 6,800 rpm and 269 lb-ft of torque at 4,300 rpm, with a six-speed automatic. That's also somewhat different than the originally reported rating of 302 hp and 270 lb-ft. Towing for the V6 is rated at 7,000 pounds.
