Status: Partially Found

The 1971 USAC Championship Car Season was the 14th season of USAC's top-level open-wheel championship. The season saw Joe Leonard claim his first of two consecutive USAC Championships. Of the races televised that year, at least seven are deemed to be missing.

1971 Jimmy Bryan 150

The 1971 Jimmy Bryan 150 was the inaugural race of the 1971 USAC Championship Car Season. Occurring on 27th March at the Phoenix International Raceway, the race would ultimately be won by Al Unser in a Colt-Ford, following a duel with his brother and Eagle-Offenhauser driver Bobby Unser.

It was the eighth running of the event, with the annual race lasting 150 miles.[1] It was one of two 1971 USAC Championship Car Season races to commence at Phoenix International Raceway, the other being the 1971 Bobby Ball 150,[2] which shall be discussed later in this article. The race, named in honour of 1958 Indianapolis 500 winner Jimmy Bryan,[3] would have ties with Phoenix events like the Desert Diamond West Valley Phoenix Grand Prix, before Phoenix races were dropped from the IndyCar schedule after 2018 following low attendance.[4]

Prior to the race, qualifying commenced with Bobby Unser winning the pole position with a record speed for Phoenix.[5] Racing-Reference claims that Unser's pole speed was 132.304 mph, while The New York Times states it was 132.218 mph.[1][5] Directly behind him was fellow Eagle-Offenhauser driver Johnny Rutherford, with previous year's winner Al Unser lining up third out of 24 competitors.[1]

The Race

With the starting order decided, the 1971 Jimmy Bryan 150 commenced on 27th March.[1] Bobby Unser maintained his lead at the start, holding it for the first 47 lap before being overtaken by Foyt on lap 48.[1] A lap later, Gary Bettenhausen made a pitstop when suddenly his Gerhardt-Offenhauser caught fire while it was being refuelled.[5][1] While Bettenhausen escaped injury, his chief mechanic Phil Casey suffered burns.[5] He was taken to the Good Samaritan Hospital, where he was deemed to be in satisfactory condition.[5] Foyt meanwhile led 26 laps before Al Unser moved into the first position on lap 74.[1] He only maintained the lead for 10 laps when his brother retook first on lap 84.[5][1]

During Bobby Unser's latest run in the first position, Foyt was forced to retire after 93 laps as his car overheated.[1] While Bobby led for the longest consecutive duration of 56 laps, he was ultimately unable to defend the first position from Al, the latter achieving an overtake on lap 140.[5][1] From there, Al controlled proceedings, claiming victory and $11,242 in prize money.[5][1] Bobby held on to finish second, the second consecutive time the Unsers achieved a 1-2 at the Jimmy Bryan 150.[1] It was also Al's third win in four Phoenix events.[5] Swede Savage, who won the 1970 Bobby Ball 150, came home third in an Eagle-Offenhauser.[5][1]

1971 Trentonian 200

The 1971 Trentonian 200 (also known as the 1971 Trenton 200) was the fourth race of the 1971 USAC Championship Car Season. Occurring on 25th April at the Trenton Speedway, the race would ultimately be won by Mike Mosley in a Watson-Ford, marking his first USAC Championship victory.

It was the tenth running of the event, with the annual race lasting just over 200 miles.[6] It was one of two 1971 USAC Championship Car Season races to occur at Trenton Speedway, the other being the 1971 Marlboro 300,[2] which shall be discussed later in this article. Trenton would continue hosting IndyCar races until 1979 before it was dropped from the schedule, with the circuit being demolished in 1980.[7]

Prior to the race, qualifying commenced with Bobby Unser winning the pole position with a speed of 155.579 mph.[6] Directly behind him was his brother and Colt-Ford driver Al Unser, with McNamara-Ford's Mario Andretti lining up third, and Mike Mosley qualifying fourth.[6] Additionally, prominent NASCAR drivers LeeRoy Yarbrough and Cale Yarborough entered the event, the former driving an Eagle-Offenhauser owned by Dan Gurney, while the latter entered a Gene White Mongoose-Ford.[8] They qualified 15th and 21st respectively out of 26 competitors.[6]

The Race

With the starting order decided, the 1971 Trentonian 200 commenced on 25th April.[6] Bobby Unser led the first lap, but dropped the first position to Al Unser on the second circuit.[6] Al held the lead for the next seven laps, before being overtaken by Andretti.[6] Unser remained in contention however, until he was forced to retire after 32 laps due to a piston failure.[9][6] Three laps later, Andretti was also out because of a broken turbocharger.[9][6] Mosley moved into the first position, where he proceeded to dominate the majority of the event.[9][6]

Aside from Mongoose-Ford's Lloyd Ruby leading from laps 78 to 80, Mosley remained in the lead, holding it for 97 laps overall.[6] However, he almost lost the race with 17 laps to go, when he spun following the end of a caution period, also being hit from behind by the Brawner-Ford of second place Steve Krisiloff.[9] Post-race, Mosley believed he hit "something, slick", presumably an oil spot.[9] He continued following a pitstop, while Krisiloff retired after hitting the wall.[9][6] Aside from this incident, Mosley comfortably claimed his first USAC Championship victory and $13,850 in prize money.[9][6] Kuzma-Offenhauser driver Wally Dallenbach finished three laps down in second, with Yarbrough taking third after Unser retired due to a broken turbocharger, a further lap down from Mosley.[9][6]

1971 Rex Mays Classic

The 1971 Rex Mays Classic (also known as the 1971 Milwaukee 150) was the sixth race of the 1971 USAC Championship Car Season. Occurring on 6th June at the Milwaukee Mile, the race would ultimately be won by Al Unser, after edging out fellow Colt-Ford driver and teammate Joe Leonard.

It was the 22nd running of the race, the annual event being held in honour of Rex Mays, a two-time AAA champion who saved fellow racer Duke Dinsmore's life during the 1948 Milwaukee 100.[10] It was one of two 1971 USAC Championship Car Season races to be held at Milwaukee Mile,[2] the other being the 1971 Tony Bettenhausen 200, which occurred on 15 August and was won by Bobby Unser in an Eagle-Offenhauser.[11] Lasting 150 miles,[12] the Rex May Classic would commence on an annual basis until it was renamed from 1988 onwards.[13]

Prior to the race, qualifying commenced with Bobby Unser winning the pole position with a speed of 118.894 mph.[14][15] Directly behind him was previous year's winner Joe Leonard, with A.J. Foyt lining up third in a Coyote-Ford.[14][15] Al Unser qualified ninth out of 24 competitors, his slow speed of 116.686 mph blamed on poor handling.[14][15] He nevertheless was looking to build on his Indianapolis 500 victory that occurred a week prior.[14][15] Meanwhile, prominent NASCAR driver Cale Yarborough was among eight competitors that ultimately failed to qualify for the race.[14]

The Race

With the starting order decided, the 1971 Rex Mays Classic commenced on 6th June.[12] Leonard shot into the lead from the first turn, holding onto it for the first 69 laps.[15][12] Meanwhile, Al Unser also made a strong start, passing four competitors on lap 2 alone.[15] By lap 7, he overtook his brother Bobby for second, and began to pursue Parnelli Jones‐Vel Miletich teammate Leonard.[15] Indeed, they ultimately were the only contenders for the first position, with Foyt retiring after a magneto failure, while Bobby Unser dropped out after 104 laps from an ignition problem that started from lap 90.[15][12]

On lap 65, Scorpion-Ford's Jimmy Caruthers spun, resulting in a caution.[15] When the race resumed on lap 70, Unser took advantage of Leonard being slowed by a backmarker to move into the first position.[15][12] Leonard attempted a comeback, but ultimately was unable to retake the lead because of handling problems caused by a lightened fuel load, with his car's right rear wheel "chattering" for the remainder of the race.[15] Thus, Unser remained in front to claim victory and $17,485 in prize money.[15][12] His average speed of 114.858 mph also set a track record.[15] Leonard finished second, while Brabham-Offenhauser driver Billy Vukovich took third, more than two laps down from Unser.[15][12]

1971 Schaefer 500

The 1971 Schaefer 500 (also known as the 1971 Pocono 500) was the first IndyCar race to be held at the Pocono International Raceway. Occurring on 3rd July as race seven of the 1971 USAC Championship Car Season, the event would ultimately be won by polesitter Mark Donohue in a McLaren-Offenhauser, his first USAC victory, after narrowly edging out Colt-Ford's Joe Leonard in the process.

Even prior to the race being held, the Schaefer 500 was considered part of USAC's Triple Crown of 500-mile races that lasted between 1971-1980, also consisting of the Indianapolis 500 and California 500.[16][17][18][19] A few days before practice began on 19th June, a ribbon-cutting ceremony commenced, which also revealed that many of the track's facilities were still being installed.[17] Despite some being sceptical about the track achieving the objective of being "the Indy of the East", many USAC, CART, and other IndyCar races would be held at Pocono to significant success.[17] It would, however, be dropped from the IndyCar schedule in 2020.[20]

Prior to the race, qualifying commenced with Mark Donohue winning the pole position with a speed of 172.393 mph.[17][19] His McLaren was built just three days beforehand as the previous car was written-off in a crash at the Indianapolis 500.[18] Directly behind him was Eagle-Offenhauser's Bobby Unser, with Colt-Ford driver Al Unser lining up third.[19] Mario Andretti meanwhile experienced multiple technical issues with his McNamara-Ford, including being forced to change his engine and turbocharger.[17] The last driver to compete in qualifying, he posted a time worthy for fifth in the field, out of 33 competitors.[17][19]

The Race

With the starting order decided, the 1971 Schaefer 500 commenced on 3rd July.[19] Donohue maintained his lead from the start, holding it for 32 laps before dropping it to Joe Leonard.[19] Leonard would lead 12 laps, with Bobby Unser achieving an overtake on lap 45, holding the first position for another 20 before Donohue regained it.[19] Throughout the 200 laps, there were four main contenders for the lead, with the first position being assumed by Donohue, Leonard, Unser, and briefly by Coyote-Ford's A.J. Foyt from laps 92-95 and 140-144.[19] Eight caution periods lasting a combined 55 laps contributed towards the 16 lead changes, as unlike at Indianapolis, where the cars maintained the distance between themselves prior to the yellow flags, Pocono forced the entire field to bunch up together, nullifying the lead margin.[17][18] Donohue was critical of the new procedure, stating "It's very heartbreaking. In my own mind, I knew I was going to lose my lead under yellow. When you get so far ahead you can't see the guy [behind you] anymore, there's little incentive to build any more of a lead."[17]

Nevertheless, Dononhue remained strong in-front, including leading from laps 157 to 190.[19] Meanwhile, a pit stop for Leonard almost ended in disaster as he pulled out of his pit prematurely due to a miscommunication, ripping a fuel hose and causing a spring-loaded clamp to remain attached to the car, forcing Leonard to pit again to remove it.[18] However, when another caution period occurred, Leonard capitalised on Donohue's briefly unresponsive engine to claim the lead on lap 191.[17][18][19] Being four car lengths behind, Donohue closed the gap from laps 192-194, before passing Leonard on his left side on the long main straight.[18][17][19] Despite Leonard providing significant pressure, Donohue was able to maintain a 1-2 second gap for the remaining seven laps to claim his first USAC victory and around $100,000 in prize money.[18][17][19] The win also marked the first victory for car owner Roger Penske.[21] Leonard finished second, with Foyt taking third, being the only other drivers on the lead lap.[18][17][19]

1971 Michigan 200

The 1971 Michigan 200 (also known as the 1971 Michigan Twin 200's) was the eighth race of the 1971 USAC Championship Car Season. Occurring on 18th July at the Michigan International Speedway, the race would ultimately be won by Mark Donohue in a McLaren-Offenhauser, achieving a double victory after winning a Trans-American race at the circuit the previous day.

It was the third running of the event, the annual race lasting 200 miles.[22] The only 1971 USAC Championship Car Season race to occur at Michigan International Speedway,[2] the track would continue hosting IndyCar races until being dropped from the schedule from 2007 onwards after failing to reach a deal with IndyCar's organisers.[23]

Prior to the race, qualifying commenced with Bobby Unser winning the pole position in an Eagle-Offenhauser with a record speed of 193.444 mph.[22] Directly behind him was Mark Donohue, who was seeking to achieve a Michigan double having won a Trans-American race the day prior.[24][25][22] Lining up third out of 26 competitors was the McNamara-Ford of Mario Andretti.[22]

The Race

With the starting order decided, the 1971 Michigan 200 commenced on 18th July.[22] Unser maintained his lead from the opening lap, holding onto it for the first 15.[25][22] However, Donohue moved into the first position on lap 16, maintaining it for 27 consecutive laps.[25][22] Unser would never regain the lead as after 35 laps, his Eagle's Offenhauser engine blew.[25][22] Donohue then made a pit stop on lap 43 that enabled Coyote-Ford's A.J. Foyt to take first place.[22] However, on lap 51, Foyt retired from the lead because of a broken turbocharger, allowing Brabham-Offenhauser driver Billy Vukovich Jr. to take over.[22]

He did not maintain the lead for long, however, as Donohue regained it on lap 53.[22] He successfully protected the first position for the remaining 48 laps, crossing the line with a lead margin of over 20 seconds to claim the Michigan double and $16,025 in prize money.[22][25] Vukovich Jr. finished second, with Roger McCluskey taking third in a Kuzma-Ford.[22][25]

1971 Marlboro 300

The 1971 Marlboro 300 (also known as the 1971 Trenton 300) was the 11th race of the 1971 USAC Championship Car Season. Occurring on 3rd October at the Trenton Speedway, the race would ultimately be won by Bobby Unser in an Eagle-Offenhauser, after having led 190 of the 200 laps. Joe Leonard also became the 1971 USAC Champion after finishing third in a Colt-Ford.

It was the third running of the event, with the annual race lasting 300 miles.[26] It was one of two 1971 USAC Championship Car Season races to commence at Trenton Speedway, the other being the aforementioned Trentonian 200.[2]

Initially, qualifying commenced for a race start on 26th September.[27] It was here that Bobby Unser broke the qualifying record at Trenton, posting a speed of 161.420 mph.[27] While this ultimately was allowed to stand, Unser and the other drivers were forced to re-qualify as the race was postponed a week because of rain.[27] When qualifying resumed, Unser again won the pole position, this time with a speed of 158.781 mph.[28][26] Directly behind him was McLaren-Offenhauser's Mark Donohue, with Colt-Offenhauser driver Al Unser lining up third out of 28 competitors.[26]

The Race

With the starting order decided, the 1971 Marlboro 300 commenced on 3rd October.[26] Unser maintained his lead from the start, ultimately proceeding to dominate the majority of the race.[28][26] The only instance where he dropped the first position was between laps 71-80, where he was forced to pit, enabling his brother Al to assume the lead.[28][26] Bobby quickly passed Al for the lead on lap 81, with the latter retiring after 134 laps because of a broken radiator.[26]

Unser led the remaining 120 laps, and was two laps ahead of McNamara-Ford's Mario Andretti when a crash involving King-Offenhauser's Steve Krisiloff necessitated a caution period.[28][26] Unser therefore claimed victory and $16,911 in prize money.[26][28] His average speed of 140.771 mph broke the 300-mile Trenton average speed record of 134.381 mph set by Andretti in 1969.[28][26] Andretti finished second, while Joe Leonard finished three laps down in third, his result being enough for him to claim the 1971 USAC Championship Car title.[29][28][26]

1971 Bobby Ball 150

The 1971 Bobby Ball 150 was the final race of the 1971 USAC Championship Car Season. Occurring on 23rd October at the Phoenix International Raceway, the race would ultimately be won by A.J. Foyt in a Coyote-Ford, his first victory in two years.

It was the 22nd running of the event, with the annual race lasting 150 miles.[30] It was one of two 1971 USAC Championship Car Season races to occur at Phoenix International Raceway, the other being the aforementioned Jimmy Bryan 150.[2] The race was named in memory of AAA driver Bobby Ball.[31]

Prior to the race, qualifying commenced with Bobby Unser winning the pole position with a speed of 134.932 mph.[30] Directly behind him was McLaren-Offenhauser's Mark Donohue, with A.J. Foyt lining up third out of 24 competitors.[30] Foyt was seeking is first USAC win in two years, as well as to climb to second in the Championship standings, with Colt-Ford's Joe Leonard having claimed the title a month prior.[32][29]

The Race

With the starting order decided, the 1971 Bobby Ball 150 commenced on 23rd October.[30] Unser maintained his lead from the start, defending it for the first 26 laps.[32][30] Nevertheless, Foyt, having passed Donohue on the opening lap, nearly made it through on lap 26 before ultimately seizing the first position a lap later.[32][30] From there, he generally controlled proceedings.[32] After having led 64 laps, he made a pitstop, enabling Kuzma-Offenhauser's Roger McCluskey to take the lead.[32][30] McCluskey would lose the lead six laps later to Brabham-Offenhauser's Billy Vukovich, Jr., the latter then dropping it to Mario Andretti in a McNamara-Ford on lap 100.[30][32]

Ultimately, none could withstand the pressure from Foyt, with him passing Andretti for the lead on 108 laps, in what turned out to be the final lead change of the event.[32][30] He therefore led the remaining 43 laps to claim victory and $9,748 in prize money.[32][30] It was Foyt's first USAC Championship win since 1969, and his first on a paved track since 1968.[32] It also confirmed he would finish runners-up for that year's Championship.[32][29] McCluskey took second, with Vukovich, Jr finishing third, a lap down from Foyt.[30]
