Doc Hudson, a beloved character from the “Cars” franchise, experienced a significant narrative arc across the series, deeply influencing the protagonist, Lightning McQueen. In “Cars,” Doc Hudson, a once-famous race car who retired into small-town obscurity after a crash, becomes a pivotal mentor to Lightning McQueen. He teaches McQueen valuable lessons and ultimately becomes his crew chief, aiding in his journey to success.

However, between the events of “Cars” and “Cars 2,” the character of Doc Hudson passes away. This development in the storyline was influenced by the unfortunate passing of Paul Newman, the actor who voiced Doc Hudson, in 2008. As a tribute to both the character and Newman’s portrayal, the Piston Cup Championship in “Cars 2” was renamed the Hudson Hornet Memorial Piston Cup, and Doc’s clinic in Radiator Springs was converted into a museum showcasing his racing career.

In “Cars 3,” Doc Hudson’s presence is felt through flashbacks and memories, as the film delves deeper into McQueen’s relationship with his late mentor. These flashbacks are central to the plot, helping McQueen to refocus and regain his confidence in racing. The film utilizes unused recordings of Paul Newman to bring Doc’s character to life in these flashbacks, ensuring his continued influence on McQueen’s journey.

The character of Doc Hudson was inspired by real-life racing legend Herb Thomas, a successful NASCAR driver in the early 1950s. This connection to a real-world figure added depth and authenticity to Doc’s character in the films.

Doc Hudson’s story within the “Cars” franchise is a blend of mentorship, legacy, and the impact of a guiding figure on one’s life and career, mirrored in the relationship between McQueen and Doc. Despite his physical absence in “Cars 3,” his teachings and influence remain a significant part of the storyline, highlighting the enduring impact a mentor can have.
