but during the race, the engine broke. CART Andretti made his CART debut in 1983, racing for the Kraco Enterprises team. He re-signed for Kraco for the 1984 season, where he managed five third-place finishes and ended his rookie season in seventh overall. In the Indianapolis 500, he finished fifth and shared the Rookie of the Year award with Roberto Guerrero. He went on to win his first IndyCar race in 1986 in the Toyota Grand Prix of Long Beach. The season became a two-man battle for the championship title, between Michael and Bobby Rahal. Andretti would take the points lead with his victory on the Milwaukee Mile. A week later, on Father's Day, Michael was leading on the final lap at Portland, when his March-Cosworth 86C ran out of fuel, allowing his father, Mario, to beat him by just 0.07 seconds. It was one of the most shocking finishes in the history of IndyCar, and the closest finish until 1997. With Rahal continuing to win races, Andretti's consistent finishing only allowed Rahal a nine-point lead in the standing with two races remaining. Andretti won a key victory in at Phoenix. Going into the season finale at Tamiami Park, Andretti was just three points behind Rahal, but neither driver were a factor in the race, with Andretti retiring with a broken halfshaft. In a one-off race with Alfa Corse, he took part in the inaugural World Touring Car race, 500 km di Monza. Paired with Alessandro Nannini, they finished 16th overall, second in class. Back in CART, he continued with Kraco in 1987, and like 1986, the championship was between Andretti and Rahal. Michael would win the Michigan 500, drawing within nine points of Rahal. With him winning in dominating fashion at Nazareth Speedway, his championship hopes remained alive, although Rahal clinched the championship at the next race. Andretti would also win the season finale, Tamiami Park. He would finish runner-up for the second season in a row. Back in June 1987, Michael joined Hendrick Motorsport to race a Chevrolet Corvette GTP in the Mid-Ohio 500 km, this time joined by his cousin, John Andretti, where they finished 11th. Following Porsche's defeat in the 1988 Daytona 24 Hours, Porsche entered a 962C at Le Mans for Mario, Michael and John. They were tremendously competitive in the first half of the race, until the Andretti family's car needed minor repairs before
