A frustrating day for the New Zealand motor racing driver Scott Dixon in the latest round of IndyCars in Detroit.
Dixon, a four time series champion, was in contention and led for a lap late in the race, but an electrial problem forced him out with 14 laps remaining.
Sebastien Bourdais won the race from Conor Daly and Juan Pablo Montoya.
Dixon officially finished 19th.
Afterwards Dixon said it wasn't a great day for his team.
"We had a new left front tire on at the start and it was a Firestone red, and I just got really loose at the start and lost positions because it had way more grip than the other three tires," Dixon said.
"Then we came in on the next stop and the Target car was super-fast. We had a fueling issue and went to the back and raced our way back to the front. The car was still really fast and we were fast with clear track in front of us. We left after our last stop and had a gearbox issue I think which led to not being able to use the clutch or shift at the end of the race."
Dixon is third in the overall standings, behind Simon Pagenaud and Helio Castroneves.
Round nine is in Texas next week.
