The American Indycar Series (AIS) was an American open wheel racing series founded in 1988 by racing driver, owner, and businessperson Bill Tempero. The series utilized year-old (and older) chassis and engines from the CART series and later the Indy Racing League. CART and IRL drivers including Buddy Lazier, Jaques Lazier, Robby Unser, and Johnny Unser found early career success in the AIS.

In the mid-1980s, the once-popular Can-Am series was withering, and most teams had already defected to CART or IMSA. The last holdouts formed "CAT" (Can-Am Teams) in 1986 to take over sanctioning of the series as part of the SCCA. Two plans emerged, one keeping the Formula 5000-based cars, and others, led by Bill Tempero who favored using old CART Indy car machines. During 1986 and 1987, the CAT races were run essentially as two-class races, with the familiar full-bodied Formula 5000 cars racing alongside ex-CART Indy cars. ^{[1] [2]} CAT folded after the 1987 season.

Tempero then broke off and started his Indy car-based series in 1988. With an emphasis on cost savings, ex-CART Indy car chassis were powered by 5.9 L (360 in³) normally aspirated, stock block Chevrolet V-8 engines. Buddy Lazier was the first season champion. Tempero himself won one race that year, and placed third in the final season points standings.

As the series slowly began to gain competitors, the teams were allowed to run a choice of two powerplants. The aforementioned stock block Chevy, or the Buick V-6 in turbocharged or normally aspirated configuration. An equivalency formula was determined to provide for competitive balance among the different engine combinations. The chassis utilized were the March, Lola, Reynard, Eagle, and Penske from CART competition. In later years, G-Force and Dallara chassis from IRL competition saw use as well. Over the years, the AIS series had a predominantly western-based schedule, but did also have races in New York, the South, Canada, and Mexico. AIS raced on mostly short ovals and road courses, occasionally splitting a bill with Weekly racing series, Late models, and other short track series. A few street circuits and "roval" races were also held.

The original American Indycar Series ceased at the end of the 2000 season. The AIS was sold to a group led by Barry Brooke and Bobby Brooks. However, the series subsequently folded permanently after only two race meets had been held in 2002. A new management team formed the United States Speedway Series (USSS), which started racing in 2001. The USSS ran for five years under mostly the same format, featuring older chassis from CART and the first generation of IRL (G-Force and Dallara); with a variety of normally aspirated and turbocharged engines. The final season of the USSS was in 2005.

1988 American Indycar Series season

The 1988 Valvoline-Machinists Union American Indycar Series ^[3] was the inaugural season of the American Indycar Series. After running mixed-class races with ex-Indy car chassis alongside the full-bodied Formula 5000-based machines in the Can-Am series in 1986–1987, this represented the first full season for Bill Tempero's Indy car series. The cars were powered by stock block Chevrolet engines, ranging from 275 to 400 cubic inch displacement. ^[3] The chassis were mostly used Marches and Lolas from CART competition in 1985–1986.

The season consisted of eight races beginning at Willow Springs in California. Three of the events were to be hosted as twin-race weekends, with the season finale consisting of twin races at Willow Springs. Three of the races were held on 1⁄2 mile ovals, and rest were held on road courses. Buddy Lazier won the first season championship, with six wins out of the eight contested races. Kevin Whitesides placed second in points, posting three runner-up finishes, and was declared the rookie of the year.

Race summaries

• Round 1: The first race of the season was held at Willow Springs. Buddy Lazier started on the pole position after winning a 5-lap qualifying heat over Bob Schader. ^[12] Lazier won the 40-lap race in dominating fashion, finishing 29.16 seconds ahead of second place Kevin Whitesides. The race was run in two 20-lap heats, with a one-hour halfway intermission for teams to make adjustments to their cars. ^[13]

• Round 2: The Illinois Grand Prix was held at the old road course at Gateway International Raceway. ^[3] Buddy Lazier won the pole position with a lap of 98.4 mph. ^[14] The race was run in two 27-lap legs, with a two-hour halfway break for teams to make adjustments to their machines. On a hot afternoon, a crowd of 6,000 were in attendance. Buddy Lazier led the most laps and won the race, despite experiencing bad tire wear over the final 15 laps. Bill Tempero, who battled with Lazier in the early going, finished second, 41.08 seconds behind. Kevin Whitesides blew an engine on Friday, then suffered a fire during the warmup lap, but he recovered to finish 4th. ^[15]

• Round 3: The Grand Prix of Colorado was held at the Mountain View Motor Sports Park road course on July 4th weekend. Robby Unser won the pole position and led-wire to wire for his first victory in the series. Buddy Lazier finish second, 4.5 seconds behind. ^[16]

• Round 4: The first oval event for the AIS was held at Shangri-La Speedway in New York. Twin 100-lap races were scheduled, but the second feature race was rained out. Only eight cars showed up, in front of a paltry crowd of roughly 2,500 spectators. Bill Tempero won the pole position, but elected to start the race at the back of the field. Buddy Lazier suffered an oil leak after practice in his March 86C, so the car was parked. His switched cars with his father and teammate Bob, who was driving an ex-Bobby Rahal March 85C. Lazier led all 100 laps en route to his third victory of the season. Only four cars were running at the finish. ^{[17] [18] [19]}

• Round 5: The AIS held its first race outside of the United States, with twin 125-lap races at Race City in Calgary. ^[20] A pit stop demonstration was held Friday at Stephen Avenue mall to promote the event. ^[21] The first race was held Saturday night. During practice on Friday, Buddy Lazier suffered a shattered brake disc on his March 85C, so he once again switched cars with his father Bob and drove the team's 86C. At that point, Bob elected to retire from driving in AIS. Lazier beat Kevin Whitesides to the finish line by 0.3 seconds. Bill Tempero finished third. ^[8]

• Round 6: The second race of the twin races at Race City in Calgary was held Sunday afternoon. Robby Unser set a new track record of 15.273 seconds to win the pole position. Bill Tempero won the race, with Unser second. Kevin Whitesides finished third, and Buddy Lazier fourth. ^[9]

• Rounds 7 and 8: The Bud Light 100 was the final event of the season. It was held as twin races at Willow Springs. Buddy Lazier won the pole position with a lap of 120.656 mph, and Robby Unser qualified second. ^[22] During the first race, Robby Unser grabbed the lead at the start, and led the first 11 laps. Buddy Lazier took the lead in turn one lap 12, and led to the checkered flag. Lazier beat Unser to the finish line by 3.04 seconds, and with the victory, mathematically clinched the 1988 AIS championship. ^[23] In the second race, Lazier started from the pole, and once again drove to victory, his sixth win of the season. Kevin Whitesides ran out of fuel during both races, but still scored enough points to place second in the final points standings. ^[24]

Race summaries

• Rounds 1 & 2: The first two races of the season were held at the 1⁄2 mile oval at Hawkeye Downs Speedway in Cedar Rapids, Iowa. ^{[43] [44]} Robby Unser won both of the 100-lap races, leading a total of 197 of the 200 possible laps. Bill Scott, driving an ethanol-powered machine, finished a close second in both races. The margin of victory was 3.75 seconds for the first race, and 1.47 seconds for the second race. Unser and Scott were the only drivers to complete all 200 laps. Bill Tempero qualified for the pole position for both races, but spun in an oil slick during the first race, then later burned a piston. ^{[45] [46]} Unser drove the weekend with a leg brace, after undergoing surgery for a broken leg he suffered in 1987. ^[47] Kenji Momota made his AIS debut, finishing third in the second race.

• Rounds 3 & 4: The second race meet was held at the 1⁄2 mile oval at I-70 Speedway. Both Buddy Lazier (the 1988 AIS champion) and Kevin Whitesides (1989 AIS rookie of the year) returned to the series after they missed the first meet. Both were attempting to qualify (unsuccessfully) for the Indy 500. ^[48] In the first race, Robby Unser started on the pole position and led the first 29 laps. Buddy Lazier took the lead on lap 30, and the two drivers raced-nose-to-tail most of the way. Unser got by Lazier for the lead on lap 87, and held him off on the last by 0.3 seconds. Meanwhile, Whitesides suffered a fuel pressure problem, and was not able to race. Bill Tempero also dropped out with engine problems on lap 81. In the second race, Robby Unser again started on the pole. On lap 10, Buddy Lazier bumped wheels with Michael Leary, and crashed into the wall in turn one. Unser pulled away and was leading when the race was stopped on lap 64 due to rain. Unser was declared the winner, with Bill Scott second. ^{[49] [50]}

• Rounds 5 & 6: The Mid-South Indy 200 was held at Memphis Motorsports Park. The event was scheduled as twin 100-kilometer races on the 1.8-mile road course. ^[51] Bill Tempero started on the pole for the first race, and Robby Unser was the winner. ^[52] In the second race, Buddy Lazier started on the pole, but dropped out on lap 4 with mechanical problems. Unser won by 3.85 seconds over Tempero, making it six consecutive victories to start the season. ^[53]

• Rounds 7 & 8: The fourth race meet was held on the 3⁄8 mile oval at Colorado National Speedway. Twin 100-lap races were held on Tuesday July 4. Due to oppressive heat, and 165° track temperature, the races were delayed for two hours. Bill Tempero won the pole for the first race. Robby Unser took the checkered flag, his seventh consecutive victory to start the season. Unser won by 2 seconds over Tempero, and Buddy Lazier finished third. ^[54] In the second race, Buddy Lazier finally snapped Unser's win streak. Lazier took the checkered flag for his first win of the season. Unser finished a close second, with polesitter Tempero third. ^[55] After eight races, the halfway point of the season, Robby Unser (196) led the points standings, with Bill Scott (127) ranked second. ^[56]

• Rounds 9 & 10: The AIS traveled to Canada for the second time, holding twin 125-lap races at Race City. On Friday, Bob Tankersley won the second annual pit stop contest at Stephen Avenue mall. Kenji Momota withdrew due to a family illness, and he was replaced by Buzz Tapley. ^[57] The first race was scheduled for Saturday August 19, but due to heavy rain, it was postponed to Sunday afternoon. Robby Unser won the pole with a track record of 14.9 seconds, and led from start to finish. Buddy Lazier finished second, but not without incident. Bill Tempero broke an oil pump in his primary car on lap 22. He parked his car in the pits, then he took over the team's back-up car (started by Arlon Koops). As Tempro was exiting the pits, he nearly tangled with Lazier, sending Lazier's car into a spin. Lazier was able to recover, and worked his way back up to second place by lap 89. Bill Scott came home third. In the second race, Greg Gorden won the pole with a new track record of 14.77 seconds. Gorden led until lap 56, when Robby Unser took over the lead. On lap 98, however, Unser suffered a broken rear end. Gorden veered to avoid contact, but spun and seized the engine. Both the first place and second place cars were out, putting Buddy Lazier into the lead. Lazier cruised to the finish, nursing a damaged gearbox. Bill Tempero finished second, driving the team's back-up car once again. ^{[58] [59]} After ten rounds, Robby Unser held a commanding points lead (254 points) over Bill Scott (137) and Buddy Lazier (143). Richard Griffin (133) was the leading rookie, and Bill Tempero (128) rounded out the top five. ^[60]

• Rounds 11 & 12: Robby Unser swept both races over Labor Day weekend at Colorado National Speedway. Unser (294 points ^[61] ) extended his championship points lead to almost 100 points over his nearest competitor Bill Scott. ^{[62] [63]}

• Rounds 13 & 14: After being rained out in August, the race meet at Shangri-La was rescheduled for the last weekend of September. On a cold, damp night, with temperatures in the 40s, Robby Unser won the first race in dominating fashion, his 11th victory of the season. ^[64] Richard Griffin finished second. During the second race, Unser dropped out on lap 87 with a failed right-front wheel bearing, his first DNF of the season. Griffin won the second race, his first AIS victory. ^[65] Johnny Unser made his AIS debut, ^[66] with a pair of 6th place finishes, driving as a teammate to his cousin Robby. Despite dropping out of the second race, Robby Unser left the weekend with enough points to mathematically clinch the 1989 AIS championship. ^[67]

• Rounds 15 & 16: The season finale was held at Willow Springs. ^[68] Bill Tempero won the pole for both races. Buddy Lazier won the first race, with Robby Unser finishing second. In the second race, Lazier dropped out with a broken motor mount. Robby Unser won the second race, his 12th victory of the season, and 13th career AIS victory overall.
