Canada's Paul Tracy dominated the opening race of the Cart season to take victory in the inaugural Grand Prix of St Petersburg, Florida.
Tracy seized the lead on lap 35 and never relinquished it to record the 20th win of his Cart career.
He paced 71 of the 105 laps and won by a comfortable 12.14 seconds from Mexico's Michel Jourdain in an identical Cosworth-powered Lolas.
A trio of Brazilians completed the top five, with Bruno Junqueira overcoming early problems to finish third, rookie Mario Haberfeld fourth and veteran Roberto Moreno fifth.
Another rookie, Frenchman Sebastien Bourdais, who started on pole, led the early
laps until the first set of pit stops.
Bourdais had to settle for 11th
But he hit the wall three laps later and required extensive repairs to a broken suspension, before eventually finishing 11th.
Britain's Darren Manning also missed out on a top five finish in only his second Cart race after suffering a mechanical problem.
Maybe I could have even got up in the top four
The 27-year-old Yorkshireman had completed 75 of the 105 laps for Walker Racing when his Ford-powered car failed him.
"The first pit stop we had a stall, which might have been the clutch starting to go," said Manning, who made his Cart debut in the British round at Rockingham last season.
"On that last stop we just couldn't get it going again. It was a bit of a shame because we were right up in sixth place.
"I think with the pit-stop strategy we probably would have ended up coming out in fifth, and the car was really good in the first few laps after the second pit stop.
Manning's next opportunity will come in the second round of the 19-race series in Monterrey, Mexico, on 23 March.
