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 recalls 638,000 U.S. SUVs, trucks for unintended braking

WASHINGTON — General Motors is recalling 638,000 U.S. sport utility vehicles and pickup trucks because a wheel-speed sensor could fail and cause unintended braking, it said Thursday. The recall covers 2015-2020 Chevrolet Suburban, Tahoe, and Yukon and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. The sensor failure could result in unintended activation of the driveline protection system, and cause unintended braking of the wheel on the opposite side of the failed sensor. That could cause the vehicle to pull to one side unexpectedly, increasing the risk of a crash, the Detroit automaker said. GM said it was not aware of any crashes relating to the issue but found 150 field claims alleging the condition caused unintended braking or lateral vehicle motion. A GM dealer in May submitted a warranty report relating to the issue in a 2018 GMC Yukon, and two days later, a GM brand quality manager submitted the report to GMÂ’s Speak Up For Safety program that tracks potential safety issues, which prompted a GM investigation and testing.

GM to build outgoing Silverado and Sierra until late 2019

As it has done with previous generations, General Motors is keeping the outgoing versions of its 1500 pickups in production despite the arrival of the all-new 2019 Chevrolet Silverado and 2019 GMC Sierra. The production of the previous, K2 generation models will begin to be wound down gradually, according to Automotive News, starting with crew cabs "early next year," and double and regular cab models following during "the early second half of next year." The old model trucks will continue to be built into "late 2019" based on market demand, GM's spokesperson Kim Carpenter said. The Chevrolet will go by the name Silverado LD, with the GMC Sierra designation still to be announced. Some of the outgoing models are built by sharing the assembly work between two GM plants. Partially finished Silverado and Sierra double cab bodies are shipped from Fort Wayne, Ind., to Oshawa, Ont., where the trucks are completed, including receiving paint. This eases the workload in Fort Wayne, where production of the new T1 generation trucks started in July 2018. In January, the Silao plant in Mexico will take on the duties of building new generation regular cab and crew cab trucks. Carpenter also said that the "Oshawa shuttle," as the shared production is called, has been very successful. As a result, 60,000 more trucks will be built than what the original production forecast initially called for. GM's latest quarterly profits, disclosed last week to be $1 billion, have been far higher than expected and will result in full-year profits far higher than what had been predicted in light of steel tariffs. GM isn't the only truck maker taking a similar multi-generation approach for 2019. Both the outgoing and redesigned Ram 1500 are in production, with the previous generation being dubbed Ram 1500 Classic. Related Video:
