Detroit race officials have pledged that there will be no repeat of the problems with the track surface that caused a two-hour stoppage during Sunday's IndyCar race on the Belle Isle street circuit.
The race was red-flagged when large sections of filler began to lift from the track surface, eventually causing Andretti Autosport's James Hinchcliffe to crash into a tire barrier just before the scheduled halfway mark.
Detroit GP chairman Bud Denker said that the track problems were the only blight on an otherwise successful revival of the Detroit event, and promised that there will be no repeat next year.
"I wanted a perfect event, and it wasn't perfect," said Denker. "It was pretty good, but it wasn't perfect. And we need to be perfect. So next year we'll make improvements."
Race winner Scott Dixon said that he was confident that the organizers would learn from the problem.
"We have to focus on the positives," said the New Zealander. "That's just out of anybody's control, and I can guarantee you, it won't happen again next year. Big credit to everybody that organized the event. It's been great to be back here, and would like to come back here next year."
Dixon's views were backed up by Target Chip Ganassi Racing teammate Dario Franchitti.
"That was a minor problem," he said. "It was fixed very quickly, and it will not happen again, I can guarantee you that. The guys running that are just too smart and too organized. We'll come back next year and go at it again."
