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.

The electric Hummer gets a new logo

GM submitted three trademark applications to government offices here and in Canada, as discovered by GM Authority. Two applications went to the U.S. Patent and Trademark Office and the Canadian Intellectual Property Office on February 4 this year, seeking to reserve the new Hummer logo, at the top in the image above. Note, the two logos aren't to scale; they're about the same size all things being equal, but we shrunk the old mark. GM sent a second application to the USPTO on February 7 requesting the brand name "Hummer" for application to "motor land vehicles, namely, automobiles, trucks and sport utility vehicles; bicycles." True, we've seen the new Hummer script stretched across the front of the coming electric pickup in a teaser clip, but the paperwork continues the process of getting the entire continent ready for the alternate universe resurrection of one of America's most notorious brands.     In 2010, gas prices were in orbit, GM committed to closing the Hummer brand, vandals were setting fire to the scattered Hummers left on dealer lots, the Chevrolet Corvette ZR1 made 638 horsepower, the eco-minded revered the Toyota Prius and the Tesla Model S was still two years away. In that year, it would have been hard to say something more bonkers than, "Hummer's coming back in ten years as an electric pickup, its top trim making 1,000 horsepower and 11,500 pound-feet of torque." But here we are. The new logo's squareness connects it to the resolute bluntness of the old mark, yet the thinner font and chopped corners both modernize the old logo and lessen its truculence. The brand appears headed the same way, with lurid specs and square-jawed looks just like old times, but having in LeBron James a more modern take on the hardcore male vibe than it once got from (unpaid) association with guys like Arnold Schwarzenegger. To be fair, old Hummer commercials always featured women in the driver's seat, or men and young boys dreaming of big adventures, or Regis Philbin chatting up models, but the marketing department couldn't — or didn't want to — outrun the lineup's reputation on the street. We'll see how the electric version and its “incredible on- and off-road capability" fare. According to the teaser site, the new Hummer's debut is still on track for May 20. If the brand manages to recreate the old H3T pickup but with an electric powertrain, it's got one buyer right here lined up already. Related Video:

GM tells NHTSA pickup truck electronic glitch is 'inconsequential'

General Motors has been enduring some serious problems with recalls recently, and it is hoping to avoid launching another major safety campaign. 200,921 2014 Chevrolet Silverado and GMC Sierra pickups are under the microscope due to a rare problem with their instruments, an issue GM calls calls "inconsequential to motor vehicle safety." The Detroit-based automaker believes that the glitch is so minor that it has filed a petition with the National Highway Traffic Safety Administration asking the government safety watchdog for permission to pass on recalling the vehicles.
The fault at issue can occasionally cause the instrument cluster to reset when drivers use the steering wheel controls to browse songs from an external media device connected to the truck's USB ports. If a song's title information exceeds 2,000 bytes, according to The Detroit News, then the instrument panel can reset, which in turn causes the gauges, shift position indicator and cruise control telltale to turn off briefly. When rebooting, other instrument panel lights may briefly illuminate without their functions actually being activated. GM claims that if this does happen, the instrument display lights go out for about 1.5 seconds and the bulb check lasts a further five seconds. However, this snafu has no actual affect on the truck's operation. The glitch is present in trucks built between January 29, 2013, and October 28, 2013.
