GM's fullsize SUVs boost highway mileage by nearly 10 percent

We met the redesigned 2015 versions of the Chevrolet Suburban and Tahoe, and the GMC Yukon and Yukon XL at the 2013 LA Auto Show. Improved gas mileage numbers have been announced to go along with the improved exteriors and interiors, with city mileage improving by seven percent and highway mileage going up by nearly ten percent; you'll now get 16 miles per gallon in the city and 23 on the highway.
The only applies to models with the 5.3-liter engine, though, not the premium Yukon Denali and Yukon XL Denali SUVs with the 6.2-liter motor. Still, the 5.3 gets you more power than previously, with 355 horsepower and 383 pound-feet of torque underfoot, on top of the improved fuel economy numbers. The 6.2-liter sticks with official mpg ratings of 15 highway, 21 city. There's a brief press release below with words straight from the horse's mouth.

2014 GMC Sierra

Is the Best GMC Truck Ever Made Good Enough?
We've got a bright aluminum Airstream camper hitched to our rear bumper as we head up Southern California's coast because GMC says that 60 percent of all full-size pickup owners will use their trucks for towing.
Rather than forcing us to absorb its capabilities in a long-winded PowerPoint presentation, the automaker brought us to Los Angeles and handed us the keys to its all-new 2014 GMC Sierra 1500. After jumping behind the wheel of a 5.3-liter V8 model, we drove up the foggy Malibu coast (locals call the soggy early-summer weather "June Gloom") and made our way to the Camarillo Airport for a towing refresher. Once completed, a brand-new 23-foot Airstream was hitched to our aft end and we were pointed towards a campground just west of Santa Barbara.

GM renders new Chevy Colorado, GMC Canyon pickups

At a series of industry seminars in Traverse City, MI today, General Motors executive vice president Dan Ammann gifted us with our first glimpse of the upcoming midsize pickup range from Chevrolet and GMC.
Just two slivers of nose are all we can see of the soon-to-be announced Chevy Colorado and GMC Canyon, though the teaser image does make plain that the pair will follow the styling cues (at least up front) found on big brothers Silverado and Sierra.
GM hasn't given us much in the way of detail in its ultra-brief press release that accompanied the teaser image, which is to be expected. We're told only that the pair of trucks are designed to be "capable, versatile and fuel-efficient alternatives to full-size pickups" and that production will start sometime in 2014, at the Wentzville, MO assembly center.
