GM readying aluminum-body fullsize pickups

Ford's extensive use of aluminum in its 2015 F-150 is a big deal. A really big deal. Big enough, in fact, that General Motors is reportedly changing its fullsize pickup strategy. According to The Wall Street Journal, The General has locked in partnerships with Alcoa Inc. and Novelis Inc. - companies that will supply aluminum for the next-generation Chevrolet Silverado and GMC Sierra trucks.
"Ford's introduction of the 2015 F-150 pickup truck was a game changer, and it's the first, not the last, conversion of this type," Novelis spokesperson Charles Belbin told the Journal. The switch to aluminum has allowed Ford to shave roughly 700 pounds off its fullsize truck's curb weight. And while official mileage ratings have not been announced, the weight loss should go a long way for improving efficiency, especially when combined other efficiency-minded improvements including better aerodynamics and new, turbocharged V6 engines.
Of course, aluminum-bodied cars are nothing new. But extensive use of aluminum in a major, best-selling product like the Ford F-150 is expected to kick off widespread use of this weight-saving material as availability rises and cost decreases. The WSJ reports that GM had originally explored the idea of moving to aluminum pickups back in 2008, but abandoned the idea due to cost concerns amid economic woes.

GMC Sierra Elevation Edition is a dark take on a tough truck

GMC proved that it knew how to make a mean-looking pickup with the 2015 Sierra Elevation Edition. For the 2016 model year, the company is applying that aggressiveness to the refreshed Sierra that already looks tougher than the predecessor. The result is a seriously brawny truck that hits the market in the first quarter of 2016. Still based on the Sierra Double Cab, this latest take on the Elevation Edition starts with all of the styling tweaks for the standard 2016 truck, including a reshaped grille and headlights. From there, the pickup gets monochromatic with body-color parts for the door handles, mirror caps, grille surround, and bumpers. Black, 20-inch wheels finish the aggressive aesthetic. Drivers get an interior packed with tech, complete with a six-speaker stereo and seven-inch infotainment system that supports Apple CarPlay and Android Auto. All the occupants can also stay connected anywhere with OnStar 4G LTE and a WiFi hotspot. Under the hood, the Elevation Edition comes standard with a 4.3-liter V6 making 285 horsepower and 305 pound-feet of torque. A 5.3-liter V8 with 355 horsepower is also optional. Regardless of the powerplant, both come with a locking rear differential and the choice of two- or four-wheel drive. Check out the video below for a closer look at last year's truck, then scroll just a little bit further for the complete press release from GMC.

The Elevation Edition – available on Sierra double cab – has a street-smart stance, thanks to body-color moldings, door handles, mirror caps and a body-color grille surround, as well as body-color bumpers. It also rolls on 20-inch black-painted aluminum wheels and is further enhanced with new Elevation Edition badging. "The Sierra Elevation Edition offers a boldly styled pickup for customers who want a truck that looks as good as it performs," said Duncan Aldred, U.S. vice president, Buick and GMC.

GM SUV window switch recall urges owners to park vehicles outside

It's not unusual for there to be a lag between an automaker announcing a recall and the official documentation showing up on the National Highway Traffic Safety Administration website. So it's no surprise that a recent GM campaign took about a month to appear in its official capacity. However, there appears to be some big differences between the two reports with potential safety implications.
In late June, GM announced that it needed to recall 181,984 examples of the Chevrolet Trailblazer, Buick Rainier, GMC Envoy, Isuzu Ascender and Saab 9-7x from the 2005-2007 model years, plus the 2006 Chevy Trailblazer EXT and 2006 GMC Envoy XL. The new documents paint a slightly different picture with 184,611 needing repaired and different model years listed.
The reason for the fix is still the same, though. It's possible for fluid to contact the master power window switch module in the driver's door, which can corrode the part. Eventually this could cause a short circuit, leaving the buttons inoperable and potentially leading to a fire. But the new NHTSA documents add an important note: "A fire could occur even while the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been made."
