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 4.3L V6 to offer segment-best 305 LB-FT

General Motors has released more information on the 4.3-liter V6 available in the 2014 GMC Sierra. The engine will serve up 285 horsepower and 305 pound-feet of torque, with a six-speed automatic transmission, and giving the V6 Sierra a maximum tow rating of 7,200 pounds in regular cab, short bed four-wheel drive configuration. GM claims that figure is 500 pounds more than the equivalent Ford F-150 equipped with a 3.7-liter V6, and 700 pounds more than the Ram 1500 with its 3.6-liter V6. Buyers can expect to see the 2014 GMC Sierra with the 4.3-liter engine start at $25,085 including destination.
While the engine does deliver more torque than either of its main competitors, it falls short on the horsepower front. The 3.7-liter V6 in the F-150 develops 302 hp while the 3.6-liter V6 in the Ram 1500 yields 305 hp. GM says fuel economy estimates for its newest entry will land later this year.

GM updating fullsize pickups for 2015

As Ford prepares to hit the market with its x-factor, aluminum-intensive F-150 and Ram sales stand tall enough to meet General Motors truck sales eye-to-eye, GM is putting the word out that it's going to add more features to its trucks and do so more regularly. An executive engineer for pickups told reporters that "a whole array" of changes are on the way as soon as the 2015 model year and then would likely come "the year after that, the year after that, the year after that."
Only GM knows the way it plans to go with its fullsize trucks, with almost everyone else - including its dealers - griping about market share at the same time as they applaud profits and hope for clarity and growth. GM raised prices on the Chevrolet Silverado and GMC Sierra not long after launch even as it was losing market share and getting called "the least successful large pickup launch over the last 15 years," further upsetting dealers, then Ram outsold the Silverado in March of this year and led GM to increase incentives. But transaction prices rose with the premium; in the first quarter of this year more than 37 percent of the trucks costing more than $40,000 were the Silverado and Sierra, leading one dealer to say of the Sierra, "You can't sell a cheap one," and the analyst who made that "least successful launch" comment to opine, "GM may have made the right call to go for price over share."
We won't know for a few months what any of these updates will be, but the rumored changes for the Silverado and Sierra appear to cover all the bases, including appearance, capability and fuel economy. Rumors run to higher gear counts, stop-start technology and diesel engines before brand-new pickups come for the 2019 model year, those next-generation models supposedly to be engineered with a lot more aluminum.
