Sammy (also known as "The Studebaker," or simply "Stu") is Doc Hudson's old rival.
Sammy was The Fabulous Hudson Hornet's old rival. During the final lap of the 1954 Piston Cup championship race, Stu intentionally sideswiped Doc, making him spin out of control and crash. Doc kept a newspaper article on the career-ending crash as a reminder never to return to the life that nearly killed him. Sammy later came to join the Radiator Springs race, little did he know that Doc Hudson was there nor was Doc expecting him.
Sammy is painted light green, with the number 23 on his doors and a chrome grille.
Sammy only appeared in the Boom! Studio comic books.
