Between 1970 and 2007, Michigan International Speedway (MIS) hosted at least one open-wheel race in every season, hosting 55 open-wheel races over 38 years. In July 2007, MIS announced that it would not hold an open-wheel auto race after the Indy Racing League was unable to provide a suitable date, and was not willing to return to the twin race format.
USAC Indy Car YearsEdit
In 1968, American open wheel racing debuted at the circuit with a Template:Convert/mi USAC Champ Car event. In 1970, USAC returned with what would become a traditional July race date. In 1973, a second USAC race was added to the Champ Car schedule, a fall race usually held in September.
CART Champ Car yearsEdit
In 1980, Ontario Motor Speedway closed, and thus Indycar racing's quadruple crown lost one of its Template:Convert/mi races. In 1981, the summer race at Michigan was expanded to a Template:Convert/mi event, replacing Ontario. NBC agreed to broadcast the race live, making it the first Template:Convert/mi Indy race to be broadcast live. Michigan joined Indianapolis and Pocono for the new Triple Crown of Template:Convert/mi races. Following the 1986 CART season, the fall race was dropped from the schedule, leaving the Michigan 500 the track's lone Indycar event.
In 1987, the Template:Convert/mi race began to sponsored by Marlboro. On network television, however, due to tobacco regulations, the race was still advertised as the "Michigan 500." From 1988-1991 the race was part of the Marlboro Million, a cash prize awarded to any driver who won the Marlboro Grand Prix, the Marlboro 500, and the Marlboro Challenge All-Star event in the same year. The prize was never won.
In 1996, the CART series held a second Template:Convert/mi race, the U.S. 500, the same day as the Indianapolis 500. The race featured a capacity crowd of around 80,000, albeit aided greatly by corporate sponsors who encouraged—and allegedly, in some cases, ordered—their employees to attend.Template:Citation needed This race was dropped immediately after its only running, partially due to a hope of running the Indy 500 in 1997.
After debris from a crash on the track killed 3 spectators in 1998, corporate sponsorship dropped off drastically, and attendance started to wane. Worse yet, MIS started a massive grandstand expansion program to accommodate the NASCAR crowds, and the smaller crowd looked even smaller in the larger grandstands.Template:Citation needed In addition, Roger Penske sold the track to ISC in 1999, and ISC lacked the emotional and economic ties to CART.
In spite of a very memorable race—one of a long string of very memorable races—the 2001 CART race was the last sanctioned by that organization at MIS.
During the CART era, safety was always a major concern due to the high speeds of the CART cars.Template:Citation needed In fact, much of the discussion by the CART Board of Directors centered on safety issues when they approved increasing the race to Template:Convert/mi in 1981. Crashes at MIS ended the careers of Chip Ganassi, Emerson Fittipaldi, Hector Rebaque and Danny Sullivan, and crashes injured Derek Daly, A.J. Foyt, Al Unser, Jr., Gordon Johncock, Mario Andretti and Bobby Rahal among others. Most crashes resulted in a total write-off of the vehicle, and high speeds resulted in many mechanical failures.
While no drivers have been killed at a MIS open-wheel event, many drivers expressed grave reservations about racing at such speeds during the CART years, and it is fair to say that few drivers looked forward to racing at MIS.Template:Citation needed Michael Andretti and Nigel Mansell both complained publicly about the high speeds; ironically, both won in the years that they complained the loudest.
In 1987, a dogleg was hastily built on the backstrech, but was never used, partially due to fear of gearbox failure, but mostly due to concern over fan reaction. No effort was ever made by CART to reduce horsepower and thus slow the cars, an approach NASCAR tackled in 1987 following a bad crash at Talladega Superspeedway that injured several spectators.
Al Unser, Jr. averaged Template:Convert/mi/h in the 1990 Marlboro 500, which is still the fastest 500 race ever run at MIS. In 1996, Paul Tracy was clocked at Template:Convert/mi/h during a practice session.||}} In 1997, Richie Hearn was clocked at 249.018. Paul Tracy set the track record for qualifying at 234.949 in 2000, which is still a track record.
In 1998, the Hanford Device was introduced. It was a spoiler attached across the back of the rear wing to greatly increase of drag. The result was a massive increase in the slipstream, and suddenly became a powerful force in Indycars. It provided wheel-to-wheel competition as well as multiple lead changes per lap. In 1998, CART counted 62 official lead changes, but since lead changes were only counted at the start-finish line, the number was much higher.
Also in 1998, three spectators were killed, and six others injured, when debris from a single-car crash flew over the Template:Convert/ft fence into the grandstands. All of the injured and dead were local residents from Michigan. In spite of the improvements to the fence, subsequent attendance in races declined greatly over previous totals.Template:Citation needed
By 2001, it was clear that change was needed. CART drivers and teams still complained about the high speeds, with the corresponding safety and cost concerns that it generated. The Hanford Device cost $50,000, and was blamed by someTemplate:Who? for the death of Greg Moore in 1999 at Fontana. In 2001, an early attempt at a "soft wall" was tried, using tires to line the exit to turn 2, but it was ineffective, as the lone crash into the tires resulted in a total loss to the car and a trip to the hospital for the driver. The popularity of the series was also in freefall with declining attendance.Template:Citation needed
In the final CART race at Michigan the lead changed 63 times.
Attrition during the CART eraEdit
Attrition has always been a factor in the 500-mile CART Michigan races.
In 1981 (the inaugural 500-mile race), only 10 cars out of 37 cars (still to this day the highest number of cars to start the Michigan 500) finished the race. The theme of the day was mechanical failures (engine, suspension, etc.), which claimed 21 cars. Crashes claimed four cars. Johnny Rutherford had a strange end to his day when he cut a tire and spun out; he did not finish. A pit fire claimed the entrant of Herm Johnson and stopped the race for over an hour.Template:Citation needed
1983 saw a spectacular finish and a bad wreck on the final lap; Rick Mears was lapping Chris Kneifel on the final lap when John Paul, Jr. drafted past entering Three; Mears spun out and was T-boned by Kniefel.Template:Citation needed
1984 was among the most brutal races of all.Template:Citation needed Phil Krueger's car was bent almost into itself in an early wreck, then Gary Bettenhausen was hit by Howdy Holmes and one car spun atop the other's rollbar. Chip Ganassi spun into Al Unser, Jr. and both tumbled into the backstretch guardrail, then on the final lap Pancho Carter tried to pass Rick Mears but shot head first into the backstretch armco, slicing off several foot-thick metal posts at their base as the car disintegrated and the cockpit tub tumbled to Turn Three.Template:Citation needed
In 1985 only 10 of 30 cars finished the race. It was an even mixture of problems as ten cars suffered mechanical failures (engine, suspension, etc.) while the other ten cars crashed. The most severe crash came when Danny Ongais tumbled down the backstretch like a stock car. Mario Andretti was forced out of a subsequent race following injury in a Turn Four crash.Template:Citation needed
In 1986 only 7 of 28 cars finished the race. That is still the Michigan 500 record for fewest cars to ever finish the race. Seven cars crashed out. The theme of the day was again mechanical failures, which took out 14 cars. Johnny Rutherford took his final Indycar win.Template:Citation needed
In 1988, 9 of 28 cars finished the race. Mechanical failures 16 cars. There was only 1 car taken out by a crash (Derek Daly). Howdy Holmes was too fatigued too continue. Johnny Rutherford's car was engulfed in flames and could not continue.
In 1994, 8 of 28 starters finished the race. Mechanical failures (engine, suspension, etc.) claimed 16 cars, crashes claimed 3 more cars and a severe pit fire (eerily similar to a severe pit fire during the inaugural Michigan 500 that stopped the race for over an hour) claimed the entrant of Adrian Fernandez. Also, at the same time this was happening Michael Andretti crashed in turn 2 (one of the 3 cars eliminated in a crashes) bringing out the yellow flag allowing the CART officials to stop the fire.Template:Citation needed
Indy Racing League yearsEdit
Starting for the 2002 season, the race became an Indy Racing League Indycar series event. In addition, the race distance was changed from Template:Convert/mi to Template:Convert/mi. In a very memorable race, Tomas Scheckter overcame bickering with team owner Eddie Cheever to beat team mate Buddy Rice. The race featured wheel-to-wheel racing, albeit at much slower speeds than the CART-sanctioned events. In addition, Sarah Fisher became the first female driver to pass for the lead under green flag conditions in an Indy-style race. Template:Citation needed
The IRL was unable to rebuild the event's attendance in spite of heavy support from the Jackson, Michigan community leadership. In many cases, the attendance for supporting stock car events was as great, if not greater, than the IRL race itself.Template:Citation needed
For 2007, the race had to move dates. The Allstate 400 at the Brickyard was moved by ESPN up one week, and created a conflict. Originally the race at Michigan was to move to July 22, but after the Indy Racing League added a new event at Mid-Ohio for that date, the race was moved to the first weekend in August. The IRL was faced with the task of selling tickets for 3 events (Mid Ohio, Michigan, and Detroit) within 6 weeks of each other, at venues that are within easy driving distance of one other.
In July, 2007, ISC announced that they would not be hosting an IRL race in 2008. The track management was not offered their traditional date for 2008 due to the same constraints that led to the 2007 date. In addition, track management wanted to return to the twin Template:Convert/mi race format in order to gain publicity, and the IRL refused to meet that request. Faced with very low attendance, as well as the task of a race only 2 weeks before a major NASCAR race, ISC terminated negotiations and announced that there would be no race in 2008.
