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 Regular Cab revealed

Despite initially launching in just the Crew Cab configuration, the lineup of 2014 GMC Sierra and 2014 Chevrolet Silverado trucks will eventually grow to include three cab sizes and three bed lengths. Oddly enough, our first look at the Regular Cab bodystyle has arrived in a General Motors press release discussing the aerodynamics of the new truck, with an image showing a Sierra Regular Cab testing in the wind tunnel. GMC's website says that Regular Cab and Double Cab models will be available by summer.
While it really didn't take too much imagination to figure out what the two-door version would look like, this Regular Cab Z71 looks pretty sharp with its standard-length (6.5-feet) bed - a longer bed will also be offered. In regards to the aero tuning of the 2014 Sierra, these images show just how far GM has gone in maximizing the truck's fuel efficiency and reducing its noise, vibration and harshness (NVH) levels. Interestingly, the press release shows visual evidence that keeping the tailgate up is best for aero - there's always been some Mythbusters-level contention about such things -but GM also says that adding tonneau covers (preferably soft) and running boards can also help improve the overall aerodynamics. Scroll down for all of this aero info in the official press release.

GMC Sierra Elevation Edition is a dark take on a tough truck

GMC proved that it knew how to make a mean-looking pickup with the 2015 Sierra Elevation Edition. For the 2016 model year, the company is applying that aggressiveness to the refreshed Sierra that already looks tougher than the predecessor. The result is a seriously brawny truck that hits the market in the first quarter of 2016. Still based on the Sierra Double Cab, this latest take on the Elevation Edition starts with all of the styling tweaks for the standard 2016 truck, including a reshaped grille and headlights. From there, the pickup gets monochromatic with body-color parts for the door handles, mirror caps, grille surround, and bumpers. Black, 20-inch wheels finish the aggressive aesthetic. Drivers get an interior packed with tech, complete with a six-speaker stereo and seven-inch infotainment system that supports Apple CarPlay and Android Auto. All the occupants can also stay connected anywhere with OnStar 4G LTE and a WiFi hotspot. Under the hood, the Elevation Edition comes standard with a 4.3-liter V6 making 285 horsepower and 305 pound-feet of torque. A 5.3-liter V8 with 355 horsepower is also optional. Regardless of the powerplant, both come with a locking rear differential and the choice of two- or four-wheel drive.
