Jerez, Spain:
Vettel, in the new Red Bull RB9 car, was just ahead of Mexico's Esteban Gutierrez in a Sauber.
Gutierrez will make his Formula One debut at the Australian Grand Prix in Melbourne on March 17.
Lewis Hamilton was third-quickest in his Mercedes, while Spain's Pedro De La Rosa made an inauspicious first appearance in a Ferrari.
He was forced to call a halt to his morning's testing on just his second lap because of a gearbox problem.
