On 8 April 2007, Power won his first Champ Car race at the inaugural Vegas Grand Prix, held on the streets of Las Vegas, Nevada, United States. He qualified on the pole position and led most laps, becoming the first Australian driver to win in the series. On 8 July, at the Steelback Grand Prix of Toronto, with rain pouring down and visibility near zero when he got behind other cars, Power decided it was time to get aggressive. Power drove from fourth to first in 14 laps, finally splashing past rookie Ryan Dalziel to take the lead with 23 minutes to go, and went on to an easy victory.
