According to a recent report, General Motors is developing aluminum-bodied pickups.

Citing unnamed insiders, the Wall Street Journal is reporting General Motors has signed agreements with Alcoa and Novelis to supply aluminum for the next-generation Chevrolet Silverado and GMC Sierra. The two companies are now reportedly looking to increase their production capacity to meet the demand.

While it sounds odd that General Motors would be signing contracts for models that aren't slated to arrive until late 2018, the Wall Street Journal says aluminum sheet for automotive bodies is in such high demand that companies need to lock in orders years ahead of time.

There's no word on how much weight the Silverado and Sierra will lose by switching to aluminum but the 2015 Ford F-150 weighs up to 700 lbs (317 kg) less than its predecessor thanks to the lightweight material.
