The NTT INDYCAR SERIES will honor the Unser family at its upcoming open test on February 17-18 at Phoenix Raceway.

The Unser INDYCAR Open Test at Phoenix Raceway will be open to all teams as they prepare for the series' return to the track on March 7 as part of a doubleheader weekend alongside NASCAR's national series. It will be the first NTT INDYCAR SERIES race at the 1.022-mile oval since 2018.

Cars will be on track Tuesday, February 17, and Wednesday, February 18. The Wednesday sessions will be open and free to the public, with an autograph session scheduled for 2:45 p.m. EST/12:45 p.m. MST.

"The name Unser is synonymous with Phoenix Raceway," INDYCAR President J. Douglas Boles said. "We're honored to salute this family's incredible accomplishments at their home track for this important Open Test, which sets the stage for INDYCAR's return to Phoenix in March. As a longtime fan of the sport, I also really appreciate that the logo for this special test features some familiar colors from cars driven by Al and Bobby, which I'm sure will bring back many great memories for our loyal fans."

Al Unser won a track-record six INDYCAR SERIES races at Phoenix since the track first started hosting series events in 1964. He also won six poles at the track as part of a career that included three series championships and four victories in the Indianapolis 500.

Bobby Unser took the checkered flag four times at Phoenix but powered to a track record 11 poles at the desert oval. He also won two series titles and three Indianapolis 500s.

Two-time series champion and two-time Indy 500 winner Al Unser Jr. finished runner-up at Phoenix four times.

"I'll speak for our family and say how pleased we are to be honored in this way by INDYCAR," Al Unser Jr. said. "Dad simply loved racing at Phoenix, and no one took it to the edge in qualifying there quite like Uncle Bobby. It was exciting to see the track added to the schedule this year, and the Open Test will be crucial for drivers and teams as they get ready for the race in March. I can't wait to see the NTT INDYCAR SERIES back at Phoenix."

Live timing and scoring from both days of the Open Test will be provided on INDYCAR.com and the INDYCAR App. Fans unable to attend the test also can follow along on INDYCAR social channels.
