In 1983, Mario Andretti signed as the primary driver, an arrangement that would carry him through the remainder of his career, until his retirement in 1994.

After the 2011 season, Carl Haas announced that the team would not run in the IndyCar Series in 2012 due to the economic climate.

At its inception, the team was a single-car outfit with championship veteran Mario Andretti, the 1978 Formula One World Champion, hired as lead driver.

In 1984, Andretti won six races, nine poles and scored a total of 10 top-ten finishes to win Newman/Haas's first CART season championship.

He became mired in a mid-season slump and later suffered a broken collarbone, dropping him to fifth in points at the end of the season.

While Andretti recovered from injury, 1980 F1 World Champion Alan Jones (who would be the lead driver for the Carl Haas owned Haas Lola Formula One team starting later in 1985) drove one race in substitution finishing 3rd at Road America in what would be his only CART start.

Andretti's second place at the 1985 Indianapolis 500 would tie for the team's best result in that event but was widely overshadowed as a highly disappointing defeat.

Andretti won the season opener at Long Beach, the powerplant's first Indy car victory.

The father and son duo of Mario and Michael Andretti excelled as one of the top teams on the Indy car circuit over the next few years.

Despite consistent success on the CART circuit, both Mario and Michael still failed to achieve victory for Newman/Haas at the Indy 500.

Michael Andretti left the team to drive for McLaren in Formula One for 1993 and was replaced by English driver Nigel Mansell who arrived on the CART circuit with much fanfare.

Mario dropped out and finished 32nd in his final Indy 500 after only 23 laps due to a fuel system failure.

At the end of the season, the burgeoning open-wheel "split" saw Newman/Haas firmly taking the side of the CART contingent.

Tracy departed to go back to Penske Michael Andretti and Christian Fittipaldi represented the team together for five seasons with Roberto Moreno driving as an occasional substitute.

Andretti won ten races during this period, finishing second in points in 1996 and continued to remain a top driver on the circuit.

Cristiano da Matta was brought over from PPI Motorsports to take over for Andretti and in his very first race for the team, he recorded a victory at Monterrey.

Fittipaldi became a full-time NASCAR driver following the season while da Matta was offered a lucrative contract to drive one of two cars for Toyota's factory-backed effort in Formula 1.

Not only was there a significant amount of team turnover but both Honda and Toyota also departed for the IRL leaving Ford as the only manufacturer.

He also was given a chance to run for Newman/Haas at Indianapolis in the team's return to the 500; Junqueira went on to finish fifth and lead 16 laps in the rain-shortened event.

He won all of the first four races, then added victories at San Jose, Montreal and Mexico City on his way to a third consecutive series championship.

Before the season ended, Scuderia Toro Rosso of Formula 1 announced that Bourdais had signed to drive as teammate to Sebastian Vettel for the team beginning in 2008.

While maintaining a full-time effort in Champ Car, the team entered singly at Indy with driver Bruno Junqueira.

Like many of the transitional teams, Newman/Haas experienced mixed results getting up to speed compared to some of the established IndyCar counterparts but did achieve two victories during the course of the season.

Late in the season, Wilson won the race at Detroit, just weeks before the death of team co-owner Paul Newman.

Graham Rahal returned but Justin Wilson was replaced by former Champ Car driver Robert Doornbos.

Doornbos left the team in early August and Oriol Servià finished out the season in the car.

Prior to the second race of the season, James Hinchcliffe was added as a second driver for selected events, including Indianapolis.

After briefly entertaining a one-off entry for Jean Alesi at Indianapolis, they withdrew and sold off their cars to Fan Force United.
