Twenty-four hours after surpassing the great Annemarie Moser-Proell's record for most downhill wins with her 37th victory in that discipline, the peerless American surged to the top of the overall World Cup standings with another decisive triumph at the Italian resort.
The 19th starter on the Olympia delle Tofane course in the Dolomites, Vonn was left facing a real challenge after Liechtenstein's Tina Weirather, wearing the 18 bib, had set a leading time of one minute 27.24 seconds.
Yet Vonn, in majestic form, made light of the task, setting out quickest of all and almost hitting a speed of 90kph as she beat Weirather's time by more than half a second in 1:26.55.
Third-placed Viktoria Rebensburg, of Germany, finished 1.15 seconds behind Vonn.

It gave the 31-year-old American her fourth win since the turn of the year following her similar weekend downhill/super-G double at Altenmarkt-Zauchensee as she continued her relentless pursuit of Ingemar Stenmark's 86 wins, the all-time World Cup landmark.
Vonn also leapfrogged Switzerland's World Cup leader Lara Gut, who finished fifth, in the race to be crowned the season's best as she homed in on a potential fifth overall title, her first since 2012.
Vonn also leads the standings in the race for the World Cup downhill and super-G titles and is second in the Super Combined.
