Race summaries
1987
The inaugural Marlboro Challenge was held at Tamiami Park, and featured a field of race winners, pole position winners, and top drivers in the points standings from the 1987 season. Drivers were required to make at least one pit stop (changing at least two tires and adding at least 5 gallons of fuel) during the 42-lap race. Raul Boesel started from the pole, but Bobby Rahal jumped into the lead at the start. Rahal gave up the lead when he pitted on lap 18, handing the lead to Emerson Fittipaldi. Fittipaldi pulled out to a 20-second lead, but he had to make his pit stop on lap 32. Meanwhile, after pitting early, Rahal was charging through the field and re-assumed the lead during Fittipaldi's stop. Fittipaldi charged to catch Rahal, but ran out of fuel on the final lap as Rahal drove to victory.[7]
1988
Heavy rain delayed the start of the race by over an hour, and the race started with a damp track at Tamiami Park. Al Unser Jr. took the early lead, but Michael Andretti who started sixth charged through the field in the early going. On lap 20, Unser and Andretti became locked in a fierce battle all the way to the finish. With the track beginning to dry, Andretti switched to slicks during his pit stop on lap 30, as did Unser. On lap 33. Andretti emerged as the leader, but the two cars were nose-to-tail. With two laps to go, the leaders were dicing through traffic, and Unser attempted to pass for the lead going into turn 9. Unser hit a deep puddle of standing water which caused the car to bobble, spin, and crash into the outside wall. Michael Andretti avoided contact, and drove to victory.[8]
1989
The race turned into a battle of fuel mileage calculations. Al Unser Jr. stretched his fuel to the finish, and captured the Marlboro Challenge in its first running at Laguna Seca. Unser ran out of fuel pulling into victory lane, after holding off second place Danny Sullivan by 4 seconds at the finish line. Sullivan grabbed second when Emerson Fittipaldi ran out of fuel on the final lap. Bobby Rahal came home third, throwing an aggressive block on Teo Fabi down the homestretch.[9]
1990
The race moved to Nazareth, the first time being held on an oval. Rick Mears started 3rd, but slipped to 4th position after the start. He worked his way to the front of the field by lap 66 (of 100). After a pit stop on lap 72, Mears made the handling adjustments he needed to pull out to a 9-second lead. However, over the final handful of laps, Mears was stuck behind the lapped car of Mario Andretti, which slowed his pace. Second place Emerson Fittipaldi closed the gap; but Fittipaldi had trouble himself getting around Arie Luyendyk. Mears finally cleared the traffic, and held on for a 4.2 second victory over Fittipaldi.[10]
1991
The event was back at Laguna Seca for 1991. Rick Mears led 42 of the 45 laps, and was leading second place Michael Andretti on the final lap. Mears was poised to win a total of $425,000 which included a $125,000 bonus for winning two of the three legs of the Marlboro Million. On the final corner of the final lap, Mears suddenly slowed. A fuel pickup problem caused the car to sputter, and Michael Andretti pounced, darting by and taking the lead in the final few hundred yards. Andretti won, becoming the first two-time winner of the Marlboro Challenge.[11]
1992
The final edition of the Marlboro Challenge was held at Nazareth, the second time at that track. Bobby Rahal and Michael Andretti dominated much of the race, leading the first 62 laps between themselves, but controversy erupted after a caution came out on lap 54. On lap 56, Rahal, Andretti, and Emerson Fittipaldi all ducked into the pits for their mandatory pit stop. Exiting the pits, CART officials ruled that both Rahal and Andretti passed the pace car before crossing the blend line, and issued both drivers a stop-and-go penalty. Rahal was later issued a second black flag penalty for an alleged fuel leak, which dropped him to 6th. The competition went from a three-car battle to just Fittipaldi, who cruised unchallenged the remainder of the race to victory.[12]
