GMC has been building trucks since before roads existed to drive them on. In this video, we trace the full story from the primitive 1902 Rapid that proved motor trucks could replace horses, through the military contracts that shaped a generation, the shock of a pickup that outran a Ferrari, all the way to a thousand-horsepower electric supertruck that can walk sideways. Every vehicle tells you something about the era it came from, and every era tells you something about where trucks are headed next.
