The smurfmobile concept in "The Surfbox Derby" was reused in the 2001 Playstation videogame "Smurf Racer" by Infogrames, where each Smurf has his own unique racing vehicle, such as Papa Smurf with his "spell book" racer.
The smurfmobile in "The Smurfbox Derby" was one of the inventions Dreamy had seen in a dream in the episode "Gargamel's Miss-Fortune".
