Herta enjoyed considerable success in the lower formulae, winning the Barber Formula Ford and Barber Saab Pro Series, and dominating the 1993 Indy Lights championship with Tasman Motorsports, race engineered by Gerald Tyler.
He graduated to IndyCar racing in 1994 with team owner A. J. Foyt, where he had several promising races before suffering a season-ending injury at Toronto.
In 1995, Herta was hired to drive for Chip Ganassi Racing. Despite a pole at Phoenix, the association was unsuccessful, with Herta managing only a 20th place in the series standings while his teammate Jimmy Vasser finished 8th. Even so, Herta landed a top ride with Team Rahal for the 1996 season.
During the next few years, Herta developed a reputation for his prowess on road courses, especially at Laguna Seca Raceway. In 1996, he was the leader until the last lap, when Alex Zanardi made a pass through the "Corkscrew" chicane and took the victory. Herta, who rarely qualified below the first row at Laguna Seca, won two events at the circuit in 1998 and 1999. At the height of Herta's career, fan interest in the Shell-sponsored driver was dubbed "Hertamania" by team owner David Letterman.
In the opening laps of the 1998 event at Elkhart Lake, Wisconsin's Road America circuit, Herta was involved in a major accident. In the 4-mile (6.4 km) road course's fifth turn, Herta got too close to the back of the car of co-owner Rahal, and spun out into a paved runoff area, facing oncoming traffic. A few seconds later, Alex Barron slid into the front of Herta's car and rode up on top of it. Both drivers were uninjured; Herta reported that Barron's car had actually hit his hands, only inches from his face.
From 2000 to 2003, Herta drove for a variety of Champ Car teams including Forsythe Championship Racing, Mo Nunn Racing, and PK Racing, but never quite regained his form from the late 1990s. In 2002 Herta drove an F1 car for the first time, piloting a Minardi at the "Thunder in the Park" event held at Donington Park. This led to speculation that he would test and even race for Minardi in F1.[citation needed]
IRL IndyCar Series
After dabbling in sports cars, he revitalized his open-wheel racing career by substituting for an injured Dario Franchitti halfway through the 2003 IRL season.
In just his third IRL start, Herta picked up his first IndyCar Series win at Kansas Speedway for Andretti Green Racing. He was retained in an expanded four-car squad in 2004, usually running development engines. On July 31, 2005, Herta took his second IndyCar Series win, defeating AGR teammate Dan Wheldon in a close finish in the Firestone Indy 400 at the Michigan International Speedway.
As of 2006, Herta has started in the Indianapolis 500 five times (1994–1995, 2004–2006) with three top ten finishes, including a best of 3rd in 2005. Bryan has his helmets painted by AliveDesignCo.com
Sports cars
On October 31, 2006, Herta was confirmed as a driver for Andretti Green Racing's new AcuraLe Mans prototype program for the 2007 American Le Mans Series season. He shared the car with Marino Franchitti, brother of his former teammate Dario Franchitti. On January 3, 2007, it was announced that Dario would also drive a limited ALMS programme with both Marino and Herta. Herta finished the season 7th in driver points with 1 class win. He also drove for A1 Team USA. At the event in Australia, Herta scored a 10th-place finish.
For the 2012 IZOD IndyCar Series season, Alex Tagliani ran the 500. The team switched to a Honda powered DW12 in May 2012 for the remainder of the season.
