https://www.carscoops.com - The Chevrolet Silverado and GMC Sierra are peas in a big, working-grade pod if we’ve ever seen them. But General Motors is out to put a little daylight between them in their latest iterations. That could be why it opted to keep the new Sierra away from the Detroit Auto Show last month, where it unveiled the new Silverado. But that won’t matter much once GMC takes to the stage in three days. That’s when it’ll finally take the wraps off the all-new Sierra, previewed in this here teaser image.
