Many real cars were adapted from automobile designs from the series. Cars bearing the logo Vaillante ran in Le Mans in 1997 and 2003: A Courage in 1997, while in 2003, Vaillante cars have been designed to be used in the Luc Besson's movie. Some fans have built a real Vaillante Grand Defi, a model which appeared several times in the comics series. The car has participated in real races, under the brand Vaillante. A model was marketed in Belgium, the Honda Civic Vaillante, of which 50 models have been produced. Automobile designer Luc Donckerwolke (current designer of Lamborghini, previously of SEAT) has drawn his inspiration from cars drawn by Jean Graton to design some real car models. He also designed the SEAT Ibiza Vaillante, exhibited at the Geneva Motor Show in 2006. It was also Luc Donckerwolke who transformed a Lola B98/10–Judd into a Vaillante and a Panoz LMP-1 Roadster-S into a Leader car in 2003 for the Besson movie. Donckerwolke also collaborated with Studio Graton on the latest titles of the series, drawing some cars featured in the albums.
