Darren Leadfoot is an Axxelo Fission that races for the Shiny Wax team in the Piston Cup Racing Series. He is painted lime green, with the number 82 painted on his doors and roof. The Shiny Wax logo is printed on his hood, as well as on his trunk. He also has a two-piece grill that not all racers have.
"Darren Leadfoot is the LAST guy you want drafting you on the final turn. Known for his sudden 11th-hour accelerations, Darren's one car who won't let anything - or anyone - stand between him and the finish line!"[1]
Despite die-cast releases of the Cars 3 Shiny Wax racer coming with the name "Darren Leadfoot", this car has several differences from Darren Leadfoot himself, such as different headlight stickers and a "uni-grill", whereas Darren Leadfoot sports a two-piece grill; this proves that Darren is different.
It is possible that he got a drastically changed body before the events of Cars 3.
