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.

2013 GMC Acadia priced from $34,875*

For those who are interested in the reworked 2013 GMC Acadia, we now know how much you can look forward to forking over. Base MSRP for the 2013 version of the full-size, three-row crossover has been set at $34,875 (*not including a $825 destination charge). If you are interested in the range-topping Denali trim, be prepared to pay $46,770.
The 2013 Acadia will come standard with a backup camera, leather-wrapped steering wheel, USB port and recycled visuals from the now-dead Saturn Outlook.
Upping to the Denali trim gets you a head-up display, blind spot monitoring system and GMC's new Rear Cross Traffic Alert system. According to GMC, most trims will also receive IntelliLink connectivity as standard equipment. The Acadia will also get the industry's first front-center airbag, an innovation it shares with other Lambda-based crossovers like the refreshed 2013 Buick Enclave. The idea behind the new tube-shaped airbag is that it can provide a buffer between driver and front seat passenger in the event of an impact, or better hold the driver in place if he or she is alone.

GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.
