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.

2023 GMC Canyon with ZR2-style off-road suspension caught in spy photos

GMC appears to be testing its redesigned 2023 Canyon pickup with an updated suspension lifted from the ZR2 variant of its Colorado twin. This heavily camouflaged prototype packs what look like Multimatic's DSSV dampers disguised with a black vinyl wrap.  Rumors have pointed to a GMC variant of the Colorado ZR2 since the midsize pickup adopted the AT4 branding for its off-road variant. GM appears to be ready to adopt the formula for GMC's more-upscale pickup as it has for the Silverado. The latter, which has now been officially confirmed, has been spied on the road with its own DSSV shocks disguised in the same fashion as those seen here. This prototype is riding high – even for an AT4 – and sports a set of knobby Goodyear Wrangler all-terrain tires. We can tell that this is a Canyon rather than another Colorado thanks to the GMC-style fog lamp design, which differs from the Colorado prototypes we've already seen testing. Like the Colorado, the redesigned Canyon is expected to be offered with just one engine: a 2.7-liter turbocharged four-cylinder lifted from the Silverado and Sierra pickups.  Look for the Canyon to debut alongside its Chevy twin sometime in the next year or two as either a 2023 or 2024 model.  Related video: This content is hosted by a third party.

GM recalls 3,300 pickups and SUVs for new ignition-switch issue [UPDATE]

UPDATE: A statement from GM about the recall has been added below. The exact total of vehicles affected is 3,296, including 3,073 of them in the US. General Motors isn't letting an ignition-switch problem grow into a massive scandal again. The automaker is recalling about 3,300 North American trucks and SUVs. They are: the 2014 Chevrolet Silverado and GMC Sierra and the 2015 Chevy Suburban and Chevy Tahoe, as well as 2015 model heavy-duty pickups, the Detroit News reports, citing an Associated Press story. The issue appears to have been caught fairly quickly. In this case, the keys can get stuck in the "start" position and then slip to "accessory" if bumped. This is because the ignition lock gears have an outer diameter that's larger than the specifications allow. When that happens the engine shuts off, and the driver loses assistance to the steering and brakes. The airbags might also be affected. The vehicles get a new ignition-lock housing to fix the problem. According to the Detroit News, an employee who experienced the problem with the switch discovered the issue, and this person then let officials at the automaker know as part of the Speak Up for Safety program. A total of five reports of the fault were discovered. However, there are no cases of injuries or crashes. The claims to the automaker's resolution program eventually tallied that GM's previous ignition switch problem included 124 deaths and 275 injuries. The company also had to recall millions of vehicles and pay significant fines to the US government. GM Statement General Motors is recalling 3,073 full-size trucks from the 2014 and 2015 model years in the U.S. Some of these vehicles may have an ignition lock actuator gear with an outer diameter that exceeds specifications, which may make turning the ignition key difficult. The ignition key could get stuck in the "start" position. This may be more likely at higher interior ambient temperatures. If the vehicle is driven with the key stuck in the "start" position, and the vehicle experiences a significant jarring event or the vehicle's interior temperature cools, the ignition lock cylinder could move out of the "start" position, rotate past the "run" position, and move into the "accessory" position, leading to loss of power steering assist, power brakes and potentially air bag deployment in certain crashes. Dealers will replace the ignition lock housing.
