Vonn clocked 1 minute, 26.16 seconds down the Olympia delle Tofane course Sunday. Maria Hoefl-Riesch of Germany finished second, 0.61 seconds behind, and Tina Maze of Slovenia placed third.
The win is Vonn's 47th career victory and moves her ahead of retired Austrian great Renate Goetschl with 46. Only Austria's Annemarie Moser-Proell (62) and Switzerland's Vreni Schneider (55) have more.
Lower-ranked skiers were still coming down the course.
The women will travel next weekend to Kranjska Gora, Slovenia, for slalom and giant slalom races.
