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 doubles miles open to its Super Cruise technology

DETROIT — General Motors said on Wednesday owners of certain vehicles equipped with its Super Cruise assisted driving system will now be able to use it on 400,000 miles (643,740 km) of North American roads, doubling the current operating area as Tesla and other automakers race to deploy hands-free cruising technology. GM's Super Cruise system, like Tesla's Autopilot system, is a driver assistance system, and does not enable true autonomous driving. Spurred by Tesla's aggressive deployment of Autopilot, and Tesla Chief Executive Elon Musk's promises of a more advanced "Full Self Driving" system, GM, Ford, Volkswagen and Mercedes-Benz are racing to deploy competing partial automation technology in major markets. At the same time, safety regulators are showing concern that drivers do not understand that Autopilot and similar systems are not designed to take over driving in every circumstance. The GM system's sensors and software allow a motorist to cruise with hands off the wheel on highways that have been mapped in detail. But the driver is expected to stay alert and ready to take over the car. GM uses technology to monitor the driver, and Super Cruise will sound alarms or slow the car to a stop if it detects that a driver is not responding. Starting later this year, GM plans to enable vehicles equipped with Super Cruise and the company's latest vehicle electronic system to operate hands-free on major, undivided highways in the United States and Canada, as well as additional miles of divided, interstate highways. Currently, Super Cruise operates only on interstate, divided highways. The expansion, enabled by wider digital mapping, will allow owners of properly equipped GM vehicles to cruise hands-free on stretches of Route 66 and the Pacific Coast Highway in the U.S. West or the Trans-Canada highway in Western Canada, GM said. Many of the new roads GM has mapped are in rural, heartland states where GM pickup trucks are popular. GM plans to offer Super Cruise as an option on its Chevrolet Silverado and GMC Sierra large pickups later this year. GM has said previously it intends to offer Super Cruise as an option on 22 models by the end of 2023. Depending on the model, Super Cruise costs $2,200 to $2,500 to add as an option.

GM recalling another 2.7 million vehicles in five separate campaigns

The recalls keep rolling in from General Motors, evidently keen to avoid repeating the mistakes of the ignition-switch debacle and clean house. This time they're all coming at once, with five separate recalls announced together covering approximately 2.7 million vehicles.
The largest of the five actions involves over 2.4 million units of the previous-generation Chevrolet Malibu and Malibu Maxx, Pontiac G6 and Saturn Aura in order to fix brake light wiring harness, which have been found to be susceptible to corrosion. The recall is separate from the 56k Aura sedans which GM recently recalled over faulty shift cables, not to mention the previous massive recall of 1.3 million vehicles - some of them the same models - but appears to have resulted from the National Highway Traffic Safety Administration investigation that started with the G6 almost a year ago.
The second-largest campaign involves the 2014 Chevy Malibu, specifically those fitted with GM's 2.5-liter engine and stop/start system, approximately 140,000 examples of which has been found to have problematic brakes. The issue does not appear to be connected to the recall of 8k Malibu and Buick LaCrosse sedans (also involving brake woes) which we reported upon last week. Four crashes have been reported in such models, but GM admits it's not yet clear if the problem was a contributing factor in the accidents.
