Scott Dixon was assessed a six-spot starting grid penalty for Sunday's Grand Prix of Toronto after once again exceeding the limit of approved engines for the season.
Dixon's starting spot on the grid will be determined in qualifying on Saturday.
It is Dixon's second starting-grid penalty of the season after a fifth different engine was installed for the June 1 Detroit Grand Prix. Not only did one of his four approved Honda engines fail before the season even started, he burnt up two in May alone.
The New Zealand native's sixth engine of the season was installed following last weekend's pair of races at Iowa. Dixon's car can no longer earn points for Honda toward the manufacturers' championship.
Dixon, 44, is alive and well in the drivers' championship standings, sitting in third place overall with 342 points after 12 starts. He has one race victory and five top-five finishes to trail both Mexico's Pato O'Ward (386) and series leader Alex Palou of Spain (515) in the standings.
Including Sunday's race at Toronto, five more races remain on the 2025 schedule, leading to the season-ending Music City Grand Prix outside of Nashville on Aug 31.
