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.

GM thinks Colorado and Canyon midsize trucks will lure crossover buyers

The invitation to come out and sample product at the General Motors Proving Grounds in Milford, MI is rarely dull, and after spending this morning driving preproduction versions of the Chevrolet Colorado and GMC Canyon all we can say is... under strict embargo. Sorry, America, we were as excited as many of you are to learn more about GM's new midsize truck range and take note of how they go down the road, but it's going to be September before we're allowed to share that with all of you. Here's to sweet suspense.
While we might not be able to talk about refinement or handling yet, we did find some of the product positioning and marketing statements from GMC and Chevy officials on hand at the program to be pretty interesting.
Of course, we all know that the literal competitive set for Canyon and Colorado is comprised of two comparatively ancient Japanese midsize trucks: the Toyota Tacoma (which currently owns this segment) and the Nissan Frontier. The Frontier's bones are as old as the 2005 model year, with 2009 marking the last time the truck was updated. The Taco was also launched in 2005, though it did see a freshening for 2012. The point remains that, in every facet from powertrain to dash plastics, the GM midsize truck twins are going to look positively space age by comparison when they hit the market for MY 2015.

GMC to get own model not shared with Chevy?

For years, GMC has existed as a brand without a single unique product, reconstituting Chevrolet trucks, SUVs and crossovers with more frosting in exchange for a few extra dollars. The Sierra is a Silverado, the Acadia a Traverse, and the Terrain an Equinox, although admittedly the latter pair are visually differentiated to a significant degree.
GMC could be set to expand beyond its Chevy-based roots, though. During last week's Detroit Auto Show press days, GM's product boss Mark Reuss was asked whether there'd ever be a GMC that wasn't taken from Chevy. "Oh, yes, you will," Reuss told the media. "The health of GMC is astonishingly good from a consideration standpoint." Reuss wouldn't elaborate on what the model could be, although we're quite happy to make some guesses. GMC has its bases fairly well covered, with a mid-size and full-size crossover, as well as a mid-size, full-size and HD pickup. We doubt GMC will be building a family sedan, sports car, or hatchback, so really, the only place we can see the brand going is into a smaller crossover.
Automotive News points out that the most recent small GMC showcar, the 2010 Granite concept (shown above), won't see production according to General Motors. That vehicle likely would have rode on GM's compact vehicle architecture, known internally as Gamma II, which underpins the Chevy Spark and Sonic, as well as the Buick Encore (and its overseas Opel/Vauxhall/Chevy counterparts).
