Race 1: Arizona Republic/Jimmy Bryan 150

Bobby Unser won the first pole in the new series history and dominated the race leading the most laps (86). However Unser had tire issues forcing an extra stop and history would show Gordon Johncock as the series first ever winner with Rick Mears second, and Johnny Rutherford in third.

Races 2 and 3: Gould Twin Dixie 125's

Johnny Rutherford would win the pole race 1. Race 1 would see Rutherford and Gordon Johncock dominate with Johncock leading the most laps (32) but would see Rutherford winning after a late race duel with Lee Kumzman who would hold on for second. Tom Sneva would take third while Johncock would take fourth.

Race 2 would see Rutherford again lead the field to the green flag (Race 2 lineup set by Race 1 finishing order). This time Rutherford would lead the most laps (61) and win. Rick Mears took second. Placing third was Al Unser Sr after he ran out of fuel on the final lap.

Also during this race weekend the CART teams that planned on entering the Indianapolis 500 were informed in a telegram from USAC that their board of directors voted unanimously to reject the entries of six key CART teams of Penske, Patrick, McLaren, Fletcher, Chaparral, and Gurney as they stated these six teams (19 cars) were alleged to be "harmful to racing" and "not in good standing with USAC."

Race 4: Indianapolis 500

After the rejected six filed an emergency injunction to be allowed to qualify and compete in the race, the injunction was granted. Race Day came around following the qualifying controversy and Rick Mears won his first of six Indy 500 poles. Both Bobby and Al Unser combined to lead 174 laps. But on lap 103 Al Unsers Day came to an end with a failed transmission. Bobby Unser was then in firm control until lap 181 when he slowed with gearbox troubles. Rick Mears would lead the remainder of the race for his first of four Indy 500 wins. A J. Foyt would finish second after losing his engine on the final lap. Mike Mosely would finish third, Danny Ongais would take fourth, Bobby Unser nursed his car to a fifth place finish with an ailing gearbox.

Races 5 and 6: Trenton Twin Indy

Race 1 would see Gordon Johncock take pole. He would lead the first 44 laps (most laps led) then lose the lead on the next lap as he had to pit, then he would spin 2 laps later losing more spots. That opened the door for Bobby Unser to win with brother Al Unser Sr taking second, and Johncock would recover for third.

Starting order for race 2 was set by race 1 finishing order so Bobby Unser started first and would finish first after leading the most laps (62). Wally Dallenbach would finish second, Johnny Rutherford finished third.

Races 7 and 8: Norton Twin 125s

In the first race, Bobby Unser won the pole, followed by Al Unser, Gordon Johncock, Wally Dallenbach, and Rick Mears.

Lee Kunzman stayed out under the caution and took the lead, while Bobby Unser's engine blew on lap 21. ^[2] Al Unser would pick up the lead after the caution flew for Danny Ongais spinning, but he miscalculated fuel mileage and ran out of fuel with 17 laps to go.^[2] This allowed Gordon Johncock to take the lead and win. Mike Mosley finished second, Johnny Rutherford third, Rick Mears fourth and Wally Dallenbach fifth. 11 laps into the race, Tom Sneva encountered a fire in his pits, but no one was hurt.

Before the second race, Bobby Unser's crew installed a new engine. ^[3] Mike Mosley led the first lap, but he had fuel pump problems the next lap and dropped out. Throughout the next 25 laps, Johnny Rutherford and Rick Mears would trade the lead, before Unser charged to the front on lap 28 and never looked back, winning the race. Rick Mears finished second on track, but he was penalized for passing cars under the yellow, dropping him to fifth. ^[4] Tom Sneva moved to second, Al Unser to third, and Gordon Johncock to fourth. Two cautions flew, the first for John Mahler's stalled car on lap 23 and the second for a crash involving Danny Ongais on lap 40.

Bobby Unser led the first 20 laps, before giving the lead to Mears. Tom Sneva then led at lap 57, followed by Unser regaining the lead on lap 69. Unser made a pit stop with 14 laps to go, giving the lead back to Sneva. ^[6] Rick Mears gambled on pit strategy, ^[7] and passed Tom Sneva with just 3 laps to go to win the final ever IndyCar race at Trenton. Bobby Unser also passed him, taking advantage of Sneva's fading tires to finish second. ^[6] Sneva fell to third, Wally Dallenbach finished fourth after running as high as second before an extended pit stop,^[6] and Johnny Rutherford finished fifth.

Gordon Johncock placed second, despite running out of gas on the final lap, Bobby Unser wound up third, Wally Dallenbach finished fourth, and Al Unser, who had tire problems of his own,^[10] finished fifth. The win was Penske's sixth straight.

Race 14: Miller High Life 150

For the last race of the year, Bobby Unser won another pole, his sixth of the year. Al Unser started second, Wally Dallenbach in third, Rick Mears in fourth, and Tom Sneva in fifth.

In the race, Al Unser jumped out to the lead on the first lap.
