Ford pulled off a bit of coup at the Detroit Auto Show last month with the introduction of the 2015 F-150 which features an all-aluminum body to help meet the upcoming fuel efficiency standards. Now, another truck maker looks to be following in the footsteps of the blue oval.
The Wall Street Journal has learned from sources familiar with the matter that General Motors is working on making the next-generation Chevrolet Silverado and GMC Sierra have aluminum bodies. The company has secured contracts with with Alcoa and Novelis Inc. to supply aluminum for the next-generation trucks, due out in late 2018.
GM's global product development chief, Mark Reuss hinted at the company possibly going towards aluminum with their trucks last month.
"We need to see how much aluminum is in it, not what they say is in it but what is actually in it. We are going to look at what they advertise as the weight savings from it and then we are going to go back and do some math.…We can play this game real easily."
Sources tell WSJ that GM will use a patented method of where multi-ringed electrodes are used to weld the aluminum panels. This eliminates a number of rivets used in the assembly of the trucks and allows the company to build a lighter and stronger truck.
