(Reuters) -Alex Palou pounced on a late restart when leader Josef Newgarden suffered engine trouble to win the IndyCar Grand Prix Road America on Sunday while former Haas Formula One team mates Kevin Magnussen and Romain Grosjean reunited on the starting grid.
Polesitter Newgarden had looked poised to give Team Penske their first win of the season until his car, with two laps to run, suddenly lost power during a restart following a late caution, allowing Palou to shoot past him into the lead and gifting the young Spaniard and Chip Ganassi Racing the win.
"It always feels awesome even if it's your lucky day or just because you have really good pace," said Palou said. "A win is a win. It's always the best thing."
Colton Herta took second for Andretti Autosport ahead of Penske's Will Power.
Reigning series champion Scott Dixon of New Zealand was fourth while Grosjean continued to shine in his maiden IndyCar season, the Frenchman finishing fifth for his second top-five result in the last four races.
