2014 GMC Sierra

Is the Best GMC Truck Ever Made Good Enough?
We've got a bright aluminum Airstream camper hitched to our rear bumper as we head up Southern California's coast because GMC says that 60 percent of all full-size pickup owners will use their trucks for towing.
Rather than forcing us to absorb its capabilities in a long-winded PowerPoint presentation, the automaker brought us to Los Angeles and handed us the keys to its all-new 2014 GMC Sierra 1500. After jumping behind the wheel of a 5.3-liter V8 model, we drove up the foggy Malibu coast (locals call the soggy early-summer weather "June Gloom") and made our way to the Camarillo Airport for a towing refresher. Once completed, a brand-new 23-foot Airstream was hitched to our aft end and we were pointed towards a campground just west of Santa Barbara.

Elvis Presley owned this GMC pickup. Now you can, too

Befitting his status as America's first rock star, Elvis Presley lived large. Among his many excesses, Elvis was well known for his prolific new-car purchases. Mostly, it seems the King favored Cadillacs and Lincolns — although, during his Army stint in Europe, he picked up a BMW 507 roadster. Here we have something different from the Elvis Presley canon: a 1967 GMC pickup. And this GMC will be crossing the block at the GAA Classic Cars auction on February 27. This GMC is one of three that Elvis purchased from Guy Caldwell Motors in Senatobia, Mississippi, almost exactly 54 years ago: on February 7, 1967. He bought a red one, a blue one, and this green one for use on his Circle G Ranch in Horn Lake, Mississippi. According to a badge on the glovebox door, this pickup is a GMC Cheyenne Super, which sounds like a fancy-pants trim level, although the truck still looks pretty bare-bones to our eyes. The steel wheels have dog-dish hubcaps, and the grille and bumpers are painted white rather than chrome. It's a standard-bed half-ton pickup and is powered by a six-cylinder engine with a three-on-the-tree column-shift manual transmission. The truck spent just over a year on the ranch before being sold off. It then went through a series of owners and several museum stints. Among the paperwork included with a sale is a letter from Elvis Presley Enterprises confirming that a GMC pickup with this VIN number was bought new by Elvis. It has now been restored, so there shouldn't be a whole lotta shakin' going on. The truck has been repainted green, although the side mirrors are different than what's shown in a vintage photo, and the chrome trim along the sides is missing. More notably, we'd like to see the "Circle G Ranch" logo it once wore on its doors be added. No pre-sale estimate is given. The final hammer price for this GMC will depend on the degree to which bidders are all shook up at the prospect of owning one of the more unusual Elvis Presley vehicles.

2021 Chevy Silverado, GMC Sierra fuel economy to go down due to global chip shortage

Production of the 2021 Chevy Silverado and 2021 GMC Sierra is continuing, but the global semiconductor chip shortage is resulting in a mid-year change. Or rather, an omission.  Basically, the availability of cylinder deactivation for the 5.3-liter V8 will be significantly reduced, resulting in a reduction of 1 mpg combined for affected models. This applies whether that engine has the six- or eight-speed automatic, as well as to both the regular Active Fuel Management and the more advanced Dynamic Fuel Management cylinder deactivation systems. DFM does remain with the pairing of 5.3-liter V8 and 10-speed automatic that comes standard on the LT Trail Boss and High Country. "Due to the micro controller shortage, the components that control AFM/DFM in the engine control module (ECM) have been removed," GM spokesperson Michelle Malcho told Autoblog. She also indicated that the engines will still have the AFM/DFM hardware in place, but that GM will not allow activation of the systems in the future with an ECM change.  Malcho also confirmed to Autoblog that the Silverado and Sierra's other engines will continue to have AFM and DFM, including the 2.7-liter turbo inline-four, 4.3-liter V6 and 6.2-liter V8. In an earlier statement to Reuters, she declined to say the volume of vehicles affected. "By taking this measure, we are better able to meet the strong customer and dealer demand for our full-size trucks as the industry continues to rebound and strengthen," Malcho wrote Reuters in an email. The change runs through the 2021 model year, she said. Malcho told Reuters it would not have a major impact on the Detroit automaker's U.S. corporate average fuel economy (CAFE) numbers. "We routinely monitor our fleet for compliance in the U.S. and Canada, and we balance our portfolio in a way that enables us to manage unforeseeable circumstances like this without compromising our overall (greenhouse gas) and fuel economy compliance," she said. GM's fleetwide fuel economy in the 2018 model year was 22.5 miles per gallon and was projected to rise to 22.8 mpg for 2019, according to a report by the Environmental Protection Agency. To meet federal CAFE requirements, automakers like GM often use credits from either earlier years where they faced less stringent rules and performed better than the requirements or buy credits from other automakers. GM said last month the chip shortage could shave up to $2 billion from this year's earnings.
