GM to unveil new SUVs at the State Fair of Texas?

With General Motors just having rolled out its new fullsize truck twins - the Chevrolet Silverado and GMC Sierra - for 2014, now it seems to be time to focus on its big SUVs. The Truth About Cars is reporting that the 2015 Chevy Tahoe/Suburban and 2015 GMC Yukon lineup will be making their debuts later next month at the State Fair of Texas, which kicks off on September 27.
To date, we've only seen spy shots of the new Chevy and GMC SUVs (shown above in Yukon XL guise). Based on those spies both trucks seem to be taking a different styling direction than their pickup truck counterparts - just check out the Ford-looking headlight design on the next-gen Chevys.
We reached out to GM for comment and heard back simply that there is no official announcement about the new Tahoe, Suburban and Yukon. Still, the report definitely makes a solid leap of logic, as Texas is a top market for GM's fullsize SUV lineup. It also appears that GM is still planning a separate launch for the next-gen Cadillac Escalade.

New Chevrolet Silverado to be revealed on Facebook on Thursday

There's not much to see here, but if you're one of those waiting for the reveal of the 2014 Chevrolet Silverado 1500, above is the teaser image that Chevrolet posted on its Facebook page. We've seen the truck in form-fitting camo before, and even less can be made out here beyond those seriously punchy Silverado-esque fenders and the knowledge that the projector-beam headlamps teased previously do indeed work. We'll have to wait until Thursday for a full perusal of the "bold exterior design" and "careful attention given to every detail" we've been promised.
Gathering intel and rumors, magnesium and aluminum contribute to the Silverado's weight loss plan, the purported "High Country" top-tier trim will contribute to luxury pickup truck competition and profit margins and the next-generation small-block V8 will contribute to improved fuel economy. On the engine note, there have been rumors of available V6 engines, and when Facebook user John Jones asked "Where's your answer to that EcoBoost Chevy?", the Bowtie replied "stay tuned on the 13th. We think you'll be pleased...".
Along with the "Raise the Bar" tag, Chevrolet says of the Silverado, "You asked, we delivered." You can watch the reveal live on Chevrolet's Facebook page at 9:30 am EST, this Thursday, December 13. The GMC Sierra 1500 will also be there, and we'll see both in person at the Detroit Auto Show in January.

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.
