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.

GMC's Denali offerings are going great guns

The Denali trim that GMC uses to denote its top-of-the-line vehicles was introduced back in 1999, partly as a way to challenge the recently introduced Lincoln Navigator. Fifteen years later, and with GMC the tenth-largest US automotive brand by itself Denali has become a sub-brand that keeps the cash registers ringing at the Renaissance Center HQ. While GMC increased sales by 9 percent in 2013, TheDetroitBureau.com reports that that Denali sales rose by 20 percent.
There are currently five Denali models in the GMC line, with the Denali trim available on all but its commercial vans. In 2010, when the now-discontinued Yukon XL Hybrid was also on sale, GMC sold 32,886 units of its top trim. Last year, that number had increased to 75,558, with almost no help from traditional marketing spends. Go to YouTube and search for "GMC Denali commercials" - the few actual commercial results are from years ago. GMC marketing director Roger McCormack tells TheDetroitBureau.com, "It's largely all been organic."
As sales have grown, so has the tide of money GMC rakes in from the additional luxury features on Denali models. The 2015 Chevrolet Tahoe starts at $44,600, yet its 2014 Yukon Denali doppelganger starts at $58,320, pricing that includes additional features like the larger 6.2-liter V8, nicer interior, head-up display and magnetic ride control suspension. The Yukon XL Denali starts at $60,965, but the article says the "average customer" likely to spend "up and above $70,000" to take one home. How does that happen? On a top-trim Tahoe LTZ, the top-tier wheel option is a set of 20-inch chrome wheels for $400; on the 'base' Yukon Denali you can swap for a set of 22-inch chrome alloys for $2,995. Add it up, and an analyst at AutoTrends Consulting said that kind of margin "epitomizes the concept of obscene profitability." We say when it comes to Denali, GMC appears to stand for "Grabbing More Cash."

2014 Chevrolet Silverado and GMC Sierra show all their sides in Detroit

There could hardly be more riding on the next-generation General Motors full-size pickup trucks, so the automaker has wisely made sure to have a selection of different models on hand at the Detroit Auto Show to show off. The 2014 Chevrolet Silverado and 2014 GMC Sierra were both officially introduced last month at a stand-alone reveal, and now they'll be on display for the public to see in various body configurations and trim levels.
The Silverado LTZ Crew Cab and Sierra SLE Extended Cab are aimed at providing more of a high-end pickup experience, while the Silverado LT Z71 Extended Cab and Sierra SLT Z71 Crew Cab should have off-road fans scouting out their favorite trails. The crew cab trucks won't go into production until sometime during the second quarter of this year - with other bodystyles coming later in the year - but we have plenty of live images from Detroit for you to enjoy.
