Sebastian Vettel is hoping to ride his 'Hungry Heidi' to his fourth straight title as the reigning Champ revealed the name of his RB9 for this season.
"Hungry Heidi, until now, you only know her by the name RB9," wrote the German on his personal website above a picture of his Red Bull race car.
Heidi is the successor to past Vettel's car names Kate, Kate's Dirty Little Sister, Randy Mandy, Luscious Liz, Kinky Kylie and, most recently, Abbey.
Vettel is chasing his fourth successive Drivers' title this season having beaten Fernando Alonso to the crown last year.
