The Shazamobile was built by Captain Marvel, with the help of his fans. Cap's fans provided the parts, and Cap provided the muscle and wisdom to create his marvel-ous motor car. And years before the Prius, the Shazamobile was an electric car - powered by the same magic lightning bolt that transforms Billy Batson into Captain Marvel!
Captain Marvel created the Shazamobile to defeat Mr. Atom in a 10 lap race at the Indianapolis Motor Speedway. At the end of the adventure, Cap returns to thank his fans for helping him make the world's mightiest automobile, and then he places the Shazamobile in their care.
Yes, Batman has his Batmobile, but only Captain Marvel has a unique, one-of-a-kind Shazamobile powered by magic lightning!!
