Due for 2018 GM has just announced plans to build the next gen Silverado and Sierra with aluminium body's. The key difference between GM's strategy and Fords aluminium strategy is that GM plans to weld panels together opposed to Fords rivet and bonded construction. GM thinks this should help shave even more weight off.
The contracts have already been secured with Alcoa and Novelis. Alcoa is the sole supplier for Ford.
Product Chief Mark Reuss:
“We need to see how much aluminum is in it, not what they say is in it but what is actually in it,” Mr. Reuss said the night before Ford introduced its truck. “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.”
It seems that GM is finally admitting what many of us knew all along, not even the recently debuted Sierra and Silverado are competitive enough for this constantly evolving marketplace. Case and point, 1/2 ton inventories for GM trucks are sitting at 151 days of supply. 2018 is a long way away for GM to compete with an un-competitive truck. This is the franchise after all...
So far aluminum seems worthy of being used in any application. Im sure they've designed it properly to take on a lot of stress and tension like what it would go through with a truck.
We just need to see more info.
