First-cousins-once-removed (Al Unser Jr.'s cousins) Robby and Johnny also drove in the Indianapolis 500. Often considered the third generation of the famous Unser racing family, Al Richard Unser is technically the fourth generation of racers to come out of the family. His great-grandfather Jerry Sr., and Jerry's brother Louis, also were racers, but neither drove in the Indianapolis 500.
During his young childhood years, he was often nicknamed "Mini Al" by the media and fans,[1][2] all with the expectation that he might follow in his family's footsteps to race professionally. However, as a child, Unser had reservations about becoming a race car driver.[3][4] For superstitious reasons, his father (Al Unser Jr.) insisted he not be named with the suffix "III".[1][2] By that time both Al Sr. and Al Jr. were stars on the Indy car circuit. Al Sr. was becoming known by the nickname "Big Al." Al Jr. for a time was known as "Little Al," thus Al Richard Unser became known for a time as "Mini Al."
As he got older and reached his teenage years, he decided to eschew the "Mini" nickname, and became known as "Just Al." When starting his professional career, he abandoned any sort of nickname, and has insisted on being referred to as Just Al (i.e., Al Unser), or by his full name, Al Richard Unser.
Unser posted three top-ten finishes in the first four races of the Infinity Pro Series season, including a 4th place at the Freedom 100 at Indianapolis. He then returned to the Toyota Atlantics, finishing the season 7th in points. He ran ten of twelve events with a best finish of 4th.
At the Indy Lights races at St. Petersburg and Indianapolis Unser competed against fellow third-generation driver Marco Andretti of the famous rival Andretti family. It was the only two times that Al and Marco raced together.
2006
In 2006, Unser drove in two Atlantics series events, but lost his ride to funding issues with his team.
2007
Unser was signed to drive for Playa Del Racing in the Freedom 100 for 2007. He drove in three other oval races, posting three top-tens in the four events.
2008
For 2008, Unser was announced as the full-time driver in the #12 car for Playa Del Racing in Indy Lights. After five races, controlling interest in the team was sold to former Las Vegas restaurateur Eric Zimmerman, who renamed it American Dream Motorsports. After finishing 11th position at Indianapolis, Unser was reportedly released by the new owner and replaced by Tony Turco, who brought sponsorship to the program. The team posted an entry for the Milwaukee 100 on May 31, but the car never took to the track.
Unser's father (Al Jr.) drove during several seasons for Galles Racing, and Al Richard once worked for Rick Galles' Chevrolet dealership.
