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 issues 4 new recalls for 90k vehicles, Chevy, Buick, GMC affected

One day after releasing an internal report that found a pattern of "incompetence and neglect" within the company, General Motors announced four more recalls that affect 89,126 vehicles. One of the recalls affects 31,520 vehicles that may contain a defect that could prevent airbags from deploying in a car accident. GM said it was aware of at least one crash in which a vehicle occupant sustained an injury because the airbags didn't deploy when they should have. The company said it was aware of other crashes that were similar in nature, but it is not yet known whether they're related to the condition, in which the shorting bar inside the driver's airbag may occasionally contact the airbag terminals. If the car and terminals are touching each other in a crash, the bags will not deploy. Vehicles from the 2012 model year are affected by the problem, and they include the Buick Verano, Chevrolet Camaro, Cruze and Sonic. GM has conducted two previous recalls for this condition involving 7,116 cars. GM is also recalling 57,512 models of the 2014 Chevrolet Silverado 1500, 2014 GMC Sierra 1500 and 2015 Silverado HD, Tahoe and Surburan, as well as the 2015 GMC Sierra HD, Yukon and Yukon XL models because their radio control modules may not work, and thus prevent certain audible safety warnings. Certain models of the 2013-2014 Chevrolet Spark and 2013 Buick Encore are being recalled for a different airbag problem, which could prevent airbags from deploying properly during a crash. And 33 2014 Chevrolet Corvettes are being recalled for yet another airbag problem, in which an internal short circuit could disable the airbags. So far in 2014, General Motors has issued 34 separate recalls that affect approximately 15.9 million vehicles – more than the company has sold in the past five years combined. GM Announces Four Recalls DETROIT – General Motors today announced three safety recalls and one non-compliance recall, all of which were reported to the NHTSA on Thursday, June 5, 2014. In all cases, customers will receive letters from GM letting them know when they can bring their vehicles into a dealership, where all repairs will be performed free of charge and courtesy transportation would be provided as needed.

REWIND: Watch the GMC Hummer EV live reveal right here

It has been a long wait to see the GMC Hummer electric pickup truck, which was teased way back at the Super Bowl in February of this year. And that wait ends tonight at 8 p.m. eastern time when GM pulls the covers off the truck. You can see the whole reveal right here, or during the World Series on Fox or "The Voice" on NBC. For everything we know about the truck, go to our reveal post here. The truck should be impressive. GMC has previously announced it will have up to 1,000 horsepower, and it will have a variety of fun features such as removable roof panels and four-wheel steering that can move the truck sort of sideways with "Crab Mode." The GMC Hummer will also be available in pickup and SUV forms. So be sure to tune in tonight for one of the biggest (figuratively and literally) vehicle reveals of the year. And keep an eye on Autoblog for all the latest on the Hummer and other vehicles.
