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.

Opel Ampera-e brings a Bolt of EV driving to Europe

The Chevrolet Bolt will take a trip across the Atlantic in 2017 to become Europe's Opel Ampera-e. General Motors won't release any specs for the foreign version yet, but these photos suggest very minor styling tweaks to the upper level of the grille and to the hatchback to add the appropriate brand emblems. We would expect the same electric motor with 200 horsepower and 266 pound-feet of torque and 60-kWh battery as the US model, too. However, the 200-mile range number might change, but only because of the differences in European testing. GM CEO Mary Barra announced the Ampera-e at the CAR Symposium in Bochum, Germany. "GM and Opel have always been convinced that electric cars will play a defining role in future mobility. The game-changing technology of the Ampera-e is a significant step toward realizing that vision," she said. The Ampera-e is also proof that General Motors loves confusing naming for its green models. If the Volt and Bolt aren't perplexing enough, the Ampera-e is just one letter off from the Ampera – the previous-gen Volt in Europe. GM no longer sells the range-extended vehicle there, so at least both names can't be in showrooms simultaneously. However, the similar monikers still might confuse some customers who think the new EV hatchback is closely related to the old sedan.

2015 Chevy Silverado, GMC Sierra recalled for steering issues

DETROIT — General Motors Co is recalling more than 1 million pickup trucks and sport utility vehicles in the United States due to issues with a temporary loss of power steering, the National Highway Traffic Safety Administration said. The recall is for 2015 models. They are: the Chevy Silverado 1500, Suburban and Tahoe, GMC Sierra 1500, Yukon and Yukon XL and Cadillac Escalade. The problem may cause difficulty steering the vehicle, especially at low speeds, increasing the risk of a crash, the auto safety regulator said in a document dated Sept. 12. The document did not highlight any reports of accidents and injuries, because of the power steering issue. GM dealers will update the power steering module software, free of charge for owners of the affected vehicles. In 2014, the No.1 U.S. automaker had recalled nearly 800,000 pickup trucks worldwide because of the same problem. GM did not immediately respond to a request for comment.Related Video:
