2014 Chevrolet Silverado

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.

2014 GMC SierraOutside, 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.

Indoors, both trucks now boast completely new interiors with a focus on soft-touch materials. Drivers are now met with a gauge cluster that features a 4.2-inch color information display, and the new trucks can be had with up to five USB ports, four 12-volt outlets and one SD card slot. The option sheet also features the IntelliLink connectivity system, displayed through a high-definition eight-inch color touchscreen interface.

In addition, the 2014 Chevrolet Silverado and GMC Sierra will be available with safety add-ons like Forward Collision Alert, Lane Departure Warning and the Driver Alert Seat, which we first saw on the Cadillac XTS. Check out the full press releases below for more information.
