2017 GMC Acadia comes into focus

The future slate of crossovers from General Motors reportedly ride on the company's new, scalable Chi platform. With short- or long-wheelbase configurations possible, the chassis conceivably allows the automaker to be more adaptable in the configuration of its CUVs. Cadillac already appears to be testing Chi for the luxury brand's future SRX/XT5, and here it is again under heavy camouflage underpinning the next GMC Acadia. Unfortunately, the Acadia is so well concealed here that it's extremely difficult to pick out any of the styling changes, though the squared-off fenders and faint GMC logo peaking through the tape on the front wheels reveal what this vehicle is. Up front, the grille appears to sit somewhat lower than the current model, and the vertical LED running lights are easy to pick out. The orientation of the taillights through the camo suggests wraparound units not too dissimilar from the current Acadia (or is that Saturn Outlook?). The next-gen Acadia is expected to debut in 2016 as a 2017 model year vehicle. The powertrain options may include the current 3.6-liter V6, a four-cylinder and possibly even a turbo V6, and GM's new nine-speed automatic might also be for offer. With a year before the reveal, take a look at these photos for a first look.

2014 Chevrolet Silverado and GMC Sierra debut all-new designs, three new engines

General Motors has finally dropped the curtain on the 2014 Chevrolet Silverado and 2014 GMC Sierra. Both trucks have undergone substantial revisions with updated versions of the company's 4.3-liter V6, 5.3-liter V8 and 6.2-liter V8 engines. In a shot across the bows of both Ford and Chrysler, GM says it won't use a V6 engine adapted from passenger car applications. Instead, it developed the 4.3-liter engine based on its proven truck-duty architecture.
All three mills will boast direct injection fuel systems as well as a new cylinder head design. Combined with a revised piston, the new engines feature a smaller combustion chamber with a compression ratio of 11:1 or higher depending on the application. Cylinder deactivation and continuously variable valve timing are all part of the recipe, and each engine is paired with a six-speed automatic transmission with auto grade breaking. So far, no fuel economy or horsepower figures have been released, though GM says the new engines will best their predecessors in both areas.
Outside, the trucks feature a number of enhancements to reduce drag and wind noise, and GM claims both the Silverado and Sierra will offer buyers some of the quietest cabins in the class. Extended cab models now feature front-hinged rear doors to allow easier access to the back passenger area, and Crew Cab buyers can now select between a five-foot, eight-inch bed or a six-foot, six-inch bed. Buyers with a mind toward going off road will also rejoice in the return of the Z71 package, complete with Rancho shocks, front tow hooks and additional under-body protection.

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.
