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.

Watch GM's new pickup crash its way to five-star NHTSA ratings

General Motors has just scored a big win with its Chevrolet Silverado and GMC Sierra pickup trucks, acing the National Highway Traffic Safety Administration New Car Assessment Program. The two full-size trucks had already netted a five-star Overall Vehicle Score in their crew-cab variants, but the new testing certifies them as five-star trucks in both regular and double-cab bodystyles, so GM's trucks offer top ratings across the board.
"Our incredibly capable trucks have been engineered to be some of the safest," Gay Kent, GM's general director of Vehicle Safety and Crashworthiness said. "We've designed the vehicle structure, strategically placed high-strength steel and developed the occupant restraint system to achieve high levels of safety performance."
The scores mark the Silverado and Sierra as the first pickups to net five-star scores since NHTSA beefed up their testing regime in 2011, a nice feather in GM's cap as it continues to slug out the pickup truck wars with crosstown rivals Ford and Ram.

Junkyard Gem: 1985 GMC Suburban K1500

General Motors has been selling Suburbans since 1935, outlasting the DeSoto Suburban, the Nash Ambassador Suburban and the Plymouth Fury Suburban. These days, the US-market GMC-branded twin to the Chevrolet Suburban wears Yukon XL badging, but GMC Suburbans were sold here from 1937 through 1999. Today's Junkyard Gem is a four-wheel-drive example of the very successful 1973-1991 Suburban generation, found in a car graveyard just outside of Reno, Nevada. The Service Parts Identification sticker on the glovebox lid tells us that this truck was part of a fleet order with some interesting RPO codes, including one for "Retail Amenity Delete." Yes, the cigarette lighter was an extra-cost option. The original engine was a good old carbureted Chevrolet 350-cubic-inch (5.7-liter) small-block V8, and this small-block may even be the one that was installed on the line in Flint, Michigan. The power rating was 165 horsepower and 275 pound-feet, not a lot of power (by our current standards) for a truck that scaled in at nearly two-and-a-half tons, but it was enough for the era. The transmission is the optional 700R4 four-speed automatic. The seat is a bench, as is proper. This is a half-ton with four-wheel-drive and the base Sierra trim level. The High Sierra and Sierra Classic packages (corresponding to Chevrolet's Scottsdale and Silverado names at the time) got you nicer-looking decorations plus some convenience features. The 1985 GMC and Chevrolet Suburbans had identical price tags, which started at $11,650 for the K1500 with 350 engine (about $24,682 in 2024 dollars). The eighth-generation Suburban showed up as a 1992 model, and it received the luxurious independent front suspension that had lived beneath C/K-series GM pickups since the 1988 model year. At some point, the tailgate from a Chevrolet Suburban was installed. Rust works slowly in Nevada, though we don't know where this truck resided before it came to the Silver State. An owner of this truck was a proud member of the International Union of Operating Engineers Local 12, which covers California and Nevada. What broke and sent this truck here? We can't know.
