Danny Sullivan

In 1980-81, he drove for Garvin Brown Racing in the SCCA Can-Am Series, scoring one victory in 1981 at the season-ending Caesar's Palace Grand Prix.

In 1982, he made his début in the PPG Indycar series, and was recruited by the Tyrrell Formula One team for the 1983 season at the request of primary sponsor Benetton, who wanted an American driver. Sullivan competed in the fifteen races of the 1983 season, scoring two points with a fifth place at the Monaco Grand Prix and finishing seventeenth in the World Drivers' Championship. He also performed strongly in the non-championship Race of Champions held at the Brands Hatch circuit in April, seeing off an early race challenge from 1980 World Champion Alan Jones, before finishing second behind reigning World Champion Keke Rosberg, finishing only half-a-second behind the Williams after 40 laps of racing.

For 1984, Sullivan returned to North America, where he competed in the CART PPG Indy Car series. He first landed at Shierson Racing, winning three races including the Pocono 500, placing 4th in points. In 1985, he moved to Penske Racing, winning the 1985 Indianapolis 500. His victory at Indy, known in auto racing lore as the "spin and win" is one of the most legendary moments in Indy 500 history.

In 1986, Sullivan was a guest star on the television show Miami Vice ("Florence Italy") playing a race car driver accused of murdering a prostitute. The episode featured some short outdoor scenes in the pit lanes of the Miami Grand Prix. Sullivan had limited dialogue in the episode; his longest piece of dialogue was in a police station interrogation scene.

Sullivan would set the pace at Indy again in 1988, qualifying second and leading 91 of the first 101 laps. Sullivan was part of the all-Penske front row with teammates Rick Mears and Al Unser Sr. A wing adjuster broke on Sullivan's car just after the halfway mark, and his car hit outside wall in turn one, ending his day. Nevertheless, he rebounded, posting finishes of 4th or better over the next six races, winning at Portland and the Michigan 500. The win at Michigan completed a career Indy car Triple Crown (Indianapolis, Michigan, Pocono). He finished the season with five top-5 finishes over the final five races, including two wins. At the second-to-last race of the season at Laguna Seca, Sullivan won the pole position, led the most laps, and won the race. With still one race remaining, Sullivan clinched the 1988 CART championship, holding an insurmountable 35-point lead. It was Sullivan's first championship title and Penske's first since 1985.

In 1989, Sullivan suffered a broken arm in a crash during practice for the Indy 500, and would miss two races. He rebounded to win the Pocono 500 in August - his second win in that event - and one other race to place a respectable 7th in points. Sullivan's last season with Penske Racing was 1990. He won two races in 1990, including the season finale at Laguna Seca. He won the pole and led wire-to-wire in his final start for Roger Penske.

In 1991, Sullivan switched to the Patrick Racing Alfa Romeo team. After going winless in 1991 in a very uncompetitive machine, he parted ways with Patrick. Sullivan won two more CART races between 1992 and 1993, driving for Galles-Kraco Racing. He scored the first win for the Galmer chassis at Long Beach. It came after he bumped teammate and race leader Al Unser Jr. on the backstretch with less than four laps to go. The incident sparked friction within the team. His later years were plagued with inconsistency, leading to a semi-retirement in 1994. His brief tenure at Galles was described as particularly toxic.

Also in 1991, the Leland Corporation released the arcade game Danny Sullivan's Indy Heat, featuring his likeness.

In 1994, Sullivan took a sabbatical from Indy car racing. After being released from Galles Racing very late after the 1993 season, Sullivan was unable to find a new ride as most seats at that point had already been filled. He joined ABC/ESPN as a color commentator. He also attempted to run selected events in the NASCAR Winston Cup Series that season. However, he failed to qualify for several events; he qualified for only one race (the 1994 Brickyard 400), and finished 33rd for a very underfunded team. In 1994, he had some guest starts for Alfa Romeo in the DTM and together with Thierry Boutsen and Hans-Joachim Stuck he was third overall with the Dauer 962 LM at the 24 Hours of Le Mans.

He returned to CART racing for one final year in 1995. His season ended early after a serious crash at Michigan International Speedway. While recovering from a broken pelvis and other injuries, he announced his retirement from open-wheel competition. He returned to ABC-TV for 1996–1998.

Sullivan was also instrumental in the Red Bull Driver Search program to find an American driver to compete in Formula One. The program successfully promoted American Scott Speed from California, who drove for the Scuderia Toro Rosso team in 2006 and 2007.

Sullivan and Michael Andretti were inducted into the Motorsports Walk of Fame on April 5, 2010, along the route of the Toyota Grand Prix of Long Beach, which both men have won.

He was inducted into the Motorsports Hall of Fame of America in 2012.
