Background[edit]
In May, Rick Mears won the Indianapolis 500 for a record fourth time.
By 1991, the Chevy Indy V-8 engine had won every Indy car race since September 1989. The dominant engine was necessary for teams to compete for wins. Entering the Michigan 500, Ilmor announced they had approved engine leases for 1992 for the Dick Simon-owned car of Hiro Matsushita and deny leases to Patrick Racing and Truesports.[2] Some believed the denials for the teams were political. In 1989, Patrick Racing left Chevrolet for Alfa Romeo and sent a Chevrolet engine to Alfa Romeo to copy for development. Truesports had led the development of the Judd engine. The controversy over who was allowed to lease engines was called "an embarrassment to CART" by journalist Robin Miller.[3]
Practice and Time Trials[edit]
Practice began on Thursday, August 1. Emerson Fittipaldi set the fastest speed at 224.134 mph. Rick Mears was second fastest at 223.678 mph. Mario Andretti was third at 223.653 mph.[4]
Arie Luyendyk was sidelined from practice after Total Petroleum obtained a restraining order to prevent his Vince Granatelli team from racing. Granatelli had partnered to co-own the team with Bob Tezak, a partnership that was dissolved in June. Granatelli pulled Total logos from the car, claiming their deal was with Tezak and not a part of the team going forward. Total demanded the logos remain on the car and went to court over it. Until the dispute was dissolved, Luyendyk and the team were forbidden from competing in IndyCar. Luyendyk was also suing Tezak for missed salary payments.[5]
On Friday afternoon, Rick Mears won the pole at a speed of 225.169 mph, breaking the track record he set in the 1986 Michigan 500. The slowest qualifier was John Jones with a speed of 200.198 mph. Emerson Fittipaldi joined Mears on the front row.[6]
A. J. Foyt suffered a blown engine in practice on Friday morning. His crew rushed to change the engine and was told he would be able to qualify at his drawn position. When the car was presented at the qualifying line, the crew was told they were too late and would have to go to the rear of the qualifying line, plus be penalized one of their two qualifying laps. Foyt called the penalty a "cheap shot" by CART.[7] Foyt withdrew from the race and loaded his equipment back onto the hauler. After meetings with MIS track president Walt Czarnecki and CART President Johnny Capels, Foyt announced he would reconsider his participation in the event. On Saturday morning, Foyt announced he would compete.[8]
A court hearing in a Detroit dissolved the restraining order and denied an injunction against the Granatelli team and allowed Luyendyk to begin activities on Saturday.[9]
On Saturday morning practice, Jon Beekhuis crashed hard in turn three. Beekhuis was briefly knocked unconscious. He was transported to a local hospital where he was diagnosed with a broken right hand, badly bruised right thigh, and was released later that day. Beekhuis had qualified 12th for the race but withdrew from the event.[10]
In the second round of qualifying, Arie Luyendyk and A. J. Foyt qualified for the race. Luyendyk's speed was the seventh fastest of the race. Foyt's was the twelfth fastest speed.[11]
On Saturday, the International Race of Champions competed at Michigan. Rusty Wallace won the 100 mile race. Al Unser Jr. and Scott Pruett were the only two drivers to compete in IROC and the Michigan 500.[12]
On hand for the IROC race, NASCAR driver Bill Elliott tested the backup car Eddie Cheever Jr., owned by Chip Ganassi Racing on Saturday morning. After making adjustments, Elliott ran a lap of 210.760 mph.[13]
Race[edit]
21 cars started the race, the smallest 500 mile Indy car race since the 1916 Indianapolis 500, which also had 21 starters. The race also saw a then-record low attendance of 50,000 spectators.[14] By comparison, the NASCAR Winston Cup race two months earlier attracted 90,000 spectators.[15]
For the first time, the Michigan 500 was started with the cars lined up in rows of two instead of rows of three. Emerson Fittipaldi led the first lap but was overtaken by Mario and Michael Andretti on the backstretch on lap two. After starting 20th, Arie Luyendyk charged to 8th after two laps. Paul Tracy, in his debut race for Team Penske, crashed exiting turn four on lap three. Tracy suffered a broken left leg and underwent surgery to repair it later that night at Methodist Hospital in Indianapolis.[16]
On the restart, Michael Andretti took the lead from his father. Shortly after, the caution came back out when John Andretti slowed on the backstretch. When racing resumed, Rick Mears took the lead.
Emerson Fittipaldi hit the wall in turn three and exited the race on lap 23. On the restart, Al Unser Jr. took the lead and paced the field for 17 laps. Michael Andretti retook the lead and built a sizable advantage. Between lap 53 and 132, Andretti led all but three laps.
The sixth caution came out on lap 125 when Scott Goodyear blew an engine and stopped on track. On the restart, Arie Luyendyk took the lead for the first time. Ten laps later, Michael Andretti blew an engine and fell out of the race. He had led a race high 82 laps. Luyendyk continued to lead with the exception of three laps during green flag pit stops.[17]
On lap 183, Bobby Rahal blew an engine and brought out a caution flag. On the restart, Arie Luyendyk jumped the restart and passed the lapped car of John Andretti before the green flag waved. A trackside caution light was damaged by debris in the Tracy crash and Luyendyk was unable to judge when the green flag was waved. He was given a stop and go penalty. Mears extended his lead over Mario Andretti and Luyendyk.
After Eddie Cheever blew an engine and brought out the final caution flag, there was a 15 lap run to the finish. Mears held his advantage over Luyendyk by several seconds. With five laps remaining, Mario Andretti blew an engine and retired. He finished fourth.
Mears won his first Michigan 500 by 3.143 seconds over Luyendyk. Mears won $173,182, which pushed his career earnings above $10 million, the first IndyCar driver to reach that mark.[18] Mears became the first driver since Gordon Johncock in 1982 to win both the Indianapolis 500 and Michigan 500 in the same year.[19]
Broadcasting[edit]
The Michigan 500 was broadcast live on television by ABC. Paul Page was the lead announcer and was joined by Bobby Unser and Sam Posey as color commentators.[20]
