Role in the series
Francesco is Diana's boyfriend in the series. He snuck into Maline's castle and found a charm and stuck it somewhere underneath of him so he can transform into a Lombax any time. He does transform into a Lombax when he is going on a date with Diana Harp and he transforms back into a car when he is racing or traveling.
Francesco is cocky and self-centered, as proven on numerous occasions with Lightning McQueen. In Cars 2, Francesco serves as the main antagonist on McQueen's part of the film, and has a rather similar persona to Chick Hicks. However, unlike Chick, Francesco seems to have a good side to him somewhere in his transmission; for example, like McQueen, Francesco was horrified to see the huge wreck after the Italy race. Also, unlike Chick, Francesco is not a cheater, just very talented and extremely arrogant.

After the race in Radiator Springs when Sonja and the others left, he droves in front of Diana and asks her to come. Which Diana begs Sonja to let Francesco join the team which she said yes. Through out the series, Francesco has been together with Diana since after Sonja's Adventures of Cars 2.
