The PC-22 debuted at 1993 Australian FAI IndyCar Grand Prix, noted for the sensational debut win of Nigel Mansell, qualifying 2nd with Fittipaldi and 3rd with Tracy. In the race, Fittipaldi scored a 2nd place finish, while Tracy retired for electrical problems. At Phoenix, the first oval race of the season, both Penskes went off, while in Long Beach Tracy scored the first win for the PC-22. In Indianapolis, Fittipaldi qualified 9th (220.150 mph), and won the event exploiting Mansell's inexperience on oval racing and Andretti's handling problems, after their dominating runs. After two races, Milwaukee and Detroit, with only one podium finish, the Penske come back to victory in Portland, with Fittipaldi 1st and Tracy 3rd. Two 1-2 wins followed, in Cleveland and Toronto, with Tracy 1st and Fittipaldi 2nd in both occasions. Nigel Mansell scored two wins at Michigan and New Hampshire as a major push for his championship bid, while Fittipaldi and Tracy at New Hampshire scored a 2nd and 3rd place respectively. Tracy won at Road America
